How to cut slopes for windows. How to install plastic slopes on windows yourself? Frameless finishing method

Production of slopes for plastic windows doing it yourself is not particularly difficult. The work does not require professional tools or special skills. But it must be taken into account that there are various situations that require the right choice finishing material. In addition, there are a sufficient number of options for this type of work. They should be considered in more detail.

When is work on slopes carried out?

There are various reasons that require installing slopes for plastic windows:

1. Cladding after installation of new structures. This is the most common case, which involves fairly large-scale work.
2. Repair work is necessary when various damages occur during operation.
3. Replacement of cladding when it is necessary to update the overall appearance of the interior or the coating has become unusable.
4. The appearance of fungus and mold. This is the most unpleasant situation in which you have to change slopes. The fact is that it is not always possible to clean the old material, which necessitates a complete replacement.

The appearance of fungus is a significant reason to think about replacing slopes

On a note! It is advisable to take into account that before performing any work, you need to decide on the finishing option. After all, it is not always necessary to carry out numerous measures; sometimes simple restoration procedures are enough.

What materials are used for the work?

The finishing of slopes of plastic windows is carried out using various materials. Initially, all types of finishing work were carried out exclusively using plaster mixtures. Although, mainly in wooden houses, there was an option using wooden panels (wide boards). The development of technology has led to the emergence of new types of products that have become widely used for such work.

The following modern types of slopes can be distinguished:

1. GKL slabs. This is an excellent solution, especially when done general work for covering surfaces with plasterboard. In this case, it is possible to create a common frame that allows you to complete the work much faster.
2. Plastic panels for walls. This option is used quite often, because you can install PVC with your own hands quite quickly, without making any noticeable effort.
3. MDF panels. This method is not used so often on window openings. The fact is that this material is not very suitable for slopes on plastic windows. The problem is that it's difficult to get the right combination.
4. Sandwich panels. It is safe to say that this type of product is only gaining popularity. The difficulty lies in the fact that the price of the material is much higher than simple panels.

Options for finishing slopes of plastic windows

It is necessary to take into account that finishing the inside of plastic windows with your own hands can be done by combining various products. For example, an excellent and fairly cheap option is considered to be a method where polystyrene foam and putty (plaster) are used simultaneously.

Possible problems

There are various requirements for how to properly make slopes on plastic windows. It should be borne in mind that all work requires extreme care and the implementation of certain nuances. If you ignore existing technologies, the following problems may arise:

• Violation of heat exchange in the room. The cold will begin to penetrate from the street, and the heat will come out. It will be very uncomfortable to be in the room. This situation occurs for two reasons:
  • The preparatory work was not completed correctly.
  • The installation of thermal insulation was carried out with violations or is simply missing.
• The appearance of fungus and mold. This nuisance especially often manifests itself when using plastic materials. The fact is that these products do not “breathe”. But the reason lies in improper sealing.
• Destruction or peeling of areas. This often happens with plaster coatings. The problem arises due to violation of preparatory work and ignoring the technology for applying the composition.
• Curvature and numerous cracks. This happens due to the fact that measuring work and installation of slopes were carried out incorrectly.

On a note! It is necessary to take into account that it is possible to veneer plastic windows with your own hands only when their installation is carried out correctly.

Different working methods depending on the situation

How to make slopes on plastic windows? It all depends on the specific situation. Various options should be considered.

Cladding after installation of new structures

Interior finishing begins with preparation, which includes the following steps:

1. All damaged areas are removed. If there is a collapse of the plaster, then it is advisable to remove everything to the base. This will avoid unnecessary problems.
2. The foam is cut off. This is done in line with window frame. The spacer wedges are removed and the empty areas are sealed.
3. A layer of primer with antiseptic additives is applied.
4. All defects are covered with the prepared solution. You need to approach deep cracks very carefully.
5. The surface should dry well, after which the last layer of primer is applied, and all joints are sealed.

Stages of preparing slopes before facing

Installation of plastic material

Work on installing slopes for plastic windows can be carried out using different technologies. Sandwich panels and PVC panels for walls can be used for cladding. They install pretty quickly. Fixation can be done in two ways: framed or frameless.

Installed plastic slopes on windows – they require virtually no maintenance, so this is the most preferable option for any situation.

This procedure allows you to perform the work in such a way that an empty space is created, which is used for laying a layer of insulation. This option is especially relevant in the case of a large installation seam.

The following technology is used:

On a note! To get a beautiful coating, it is advisable to cut the timber at an angle using a plane. This will make it possible to set the slopes at the desired angle.

Installation of PVC starting profile

• There is empty space between two bars. It is filled with insulation.
• Everyone is filmed required sizes. A diagram of all the details is drawn up. The obtained parameters are transferred to the material. Parts are cut using an electric jigsaw or hand saw on metal.
• Installation of slopes on windows begins with the fact that each part is inserted into the groove of the starting profile. Along the outer edge, fixation occurs with glue or staples.

Fastening the plastic slope

• Joints appear between the elements, which are sealed with sealant.
• Next comes the finishing of the outer perimeter. For this purpose, overhead plastic corners are used. They are cut to the required size.

Installation of decorative corners

But how to install parts without building a frame? This option is used if the installation seam is thin enough.

The work is carried out according to the following scheme:

• The surface is being prepared.
• All required dimensions are taken. Parts are cut out.
• Polyurethane foam is applied to the underside of the panel. The layer should not be very thick, because it expands quickly.
• The fragments are pressed to the selected area and torn off for a few minutes. This is necessary to allow the adhesive to expand slightly.
• Now every detail is put in its place. Everything is secured with masking tape.
• After drying, the external and internal corners are lined with overhead corners.

Installation of slopes with glue requires high-quality preparation of the base

On a note! If a problem arises: how to make slopes from gypsum board slabs, then its solution will be the same as in the case of plastic panels. That is, the above technologies are completely repeated.

Replacement for interior renovation or renovation

Sooner or later, the need arises to update the overall appearance of the interior. It is then that the slopes on plastic windows are replaced. Also, slopes need to be replaced if cosmetic work has been carried out on the premises, which has led to damage to the coating.

Removing the old layer of plaster and applying a new one

The procedure requires some experience. The fact is that you need to use plaster on such surfaces extremely carefully in order to achieve perfect evenness. Any defects will immediately become visible, because such areas receive a sufficient amount of light.

1. Gets confused old layer. It is advisable to remove all material to create an exposed base.

Removing Old Finish

• Dust is cleared and dirt is removed. This finishing of internal slopes assumes that everything will be impregnated with primer.
• The required amount of solution is prepared. Beacons are immediately displayed. For greater effect and simplification of work, a guide rail is installed.

On a note! Exactly correctly exposed wooden beam– this is the key to success. It is necessary to determine the thickness of the layer and the level of inclination. Therefore, it is placed along the outer edge of the window opening so that it protrudes beyond the edge as much as the composition is supposed to be applied. The rail must be attached around the entire perimeter to obtain a single level.

Plastering a slope

Window slopes made of plastic: self-installation - 2 methods

After installing plastic windows, the window opening does not look the best: foam, pieces of plaster stick out, and the wall material is visible in places. All this “beauty” is closed in various ways, the most practical, fast and inexpensive of which is plastic slopes. It is better to make them from sandwich panels (two layers of plastic with polypropylene foam between them). They are dense, durable, made of good material.

There are two main methods for installing plastic slopes: with and without a starting profile. Both come with step-by-step instructions and photos. Decide for yourself how to attach slopes to plastic windows. Both methods give good results.

Photo report 1: installation of slopes from sandwich panels without starting profiles

This method is suitable when the window is installed so that the distance from the window frame to the opening wall is too small. In this case, installation with a starting profile (see below) is either very difficult or - usually from the hinge side - completely impossible.

After installing the plastic window, the following picture was observed.

The installation of slopes for plastic windows begins with preparing the opening: we cut off the remaining foam with a stationery knife. It is easy to cut, just don’t overdo it, cut it flush and don’t cut it out - the foam both holds and insulates the frame. Pieces of plaster that interfere and protrude are also removed. If they hold up well and do not protrude beyond the plane of the future slope, you can leave them - the foam will slide less.

Then, around the perimeter of the window we nail (we place it on dowels if the wall is concrete) a thin strip - 10*40 mm - with the wide side facing the slope.

Nailed around the perimeter of the rail

Usually they don’t level it, they nail it as is, but if you want, you can make it level by placing pieces of plywood, thin boards, etc. in the right places.

Groove for plastic sandwich panel

Now you need to cut the plastic panels correctly. You can do it in a standard way: using measurements, you can make a stencil. It seems easier with a stencil. Take a sheet of paper larger than your window (I had old wallpaper). Apply to the slope, crimp, bending the excess. Cut along the curved lines, try on, adjust as necessary.

It is more convenient to start from the upper part of the opening. Having made a paper stencil, we outline it on the plastic. Considering that about 1 cm will go into the foam groove, add this centimeter along the edge that will be inserted there. We cut it out with a small margin - it’s easier to cut it off than to cover it up later.

We cut it with a hacksaw and a metal blade, try it on, adjust it so that the plastic stands up straight, without bending. We level it so that the panel is flush with the plaster. The edge turns out to be almost even; where necessary, we trim it with a file.

Inserted plastic slope top

Having removed the tried-on and adjusted strip, along the outer edge that will be nailed to the plank, we drill holes according to the thickness of the nails, retreating about 0.5 cm from the edge. This will make it easier to attach and will not damage the plastic.

We put it in place again, take a balloon with mounting foam and short “sprays” to fill the gap with foam. We try to get as deep as possible, but don’t pour too much: when it swells, it can distort the plastic.

Fill it out like this

There are several points to consider when working with polyurethane foam. If the plastic is smooth, the foam does not have a very good grip on it. To improve it, either treat the surface that faces the wall with sandpaper, and/or prime it with something to improve adhesion. The second nuance: for normal polymerization of the foam, moisture is needed. Therefore, before installing the plastic, the slope is sprayed with water from a spray bottle. Naturally, there should be no dust on the wall - it should be swept away with a brush or removed with a vacuum cleaner. If the plaster or mortar is loose, the opening is pre-treated with a penetrating primer, which will bind the concrete particles together.

Then we lift the panel, pressing down the foam, insert the nails into the holes and fasten the outer edge to the bar. The inner one rests against the window frame.

Fixed top plastic panel on the window slope

Using the same technology - cut out a paper template, try it on, transfer it to plastic - cut out a plastic side. Here you need to be especially precise so that the gap between the slope panel and the window sill (upper slope) is minimal. To do this, the edge will have to be sanded. To make the edge smooth it is easier, it is more convenient to process it with sandpaper attached to a smooth block, a file or a sharpening stone (half a circle, as in the photo).

Processing the edge of a plastic panel

We adjust it until it matches perfectly (as best as possible) at the top and bottom, and install it in place, driving one edge into the groove near the window. When the result is satisfactory, we level the outer vertical edge to the same level as the wall plaster. You can do this with a stationery knife on the spot, or you can draw a line on the panel (with a pencil, a thin marker, scratch it with something sharp) and then modify it with whatever is convenient.

Having removed it, we also drill holes for nails along the outer edge. We install the panel in place, take foam, and fill the gap from bottom to top. Too much foam is not good here either, as it can bend the plastic. Therefore, we fill it in short portions, trying to fill it as deeply as possible.

On the vertical parts of the slopes, you can do it differently: apply foam to the panel ready for installation along the far edge, which goes under the frame, before installation. The strip is made continuous or applied as a small snake. Only you need to do this not from the very edge, but stepping back a little. Then the plastic part is inserted into the cut-out groove, positioned as needed, and the rest of the gap is filled with foam (do not forget to wet the wall before installation). Once filled, press, level, and secure with nails into the bar.

The upper and lower joints are fixed with masking tape until the foam polymerizes.

To prevent the foam from moving the edges of the slope during the polymerization process, tape the joint at the top and bottom with masking tape. No matter how hard you try to adjust the plastic evenly, gaps, albeit small ones, remain. They can be covered with acrylic. It is sold in tubes like polyurethane foam, is placed in the same mounting gun.

Squeeze the strip into the gap, rub it, level it, remove the excess with a damp soft cloth or sponge. This operation must be performed on small areas and wipe it carefully - clean. As long as the acrylic has not hardened, it cleans up well. Then - with great difficulty. It is more convenient to start sealing cracks from the top - right away - horizontal panel slopes, then joints, then move down first along one side, then along the other. The last to be sealed are the joints with the window sill.

After drying - 12-24 hours, depending on the sealant (written on the tube), acrylic may be drawn into the seam - this is if the cracks are large. Go through all these places a second time using the same method. After the second layer has dried, if there are any roughness or unevenness, they can be smoothed out with fine-grain sandpaper, folded in half. In general, it is better to carefully level it while it is still wet, otherwise you may scratch the plastic.

Installed plastic slopes

That's it, the plastic slopes are installed. After the final polymerization of the foam, the bevels must be puttied, leveling with the surface of the walls. After this you can remove the protective blue film. As a result, the window will look something like this.

Window with plastic slopes (sandwich panels)

When installing these plastic slopes, sandwich panels were used. These are two layers of plastic, between which there is a layer of foamed propylene foam. Using the same technology, you can make a window frame from inexpensive plastic window sills or white PVC wall panels. The most unreliable material is panels: even wall panels are pressed through quite easily, to same thing If the front layer of plastic is thin (cheap), then the jumpers are visible in the light. This is not the case with sandwich panels and plastic window sills. And it takes a lot of effort to push through, and there are no jumpers even for clearance.

Photo report 2: installing plastic slopes with a starting profile

The installation of plastic slopes using this technology begins with the preparation of the window opening. We cut off the foam evenly, remove everything that does not adhere well, clean off the dust, and if necessary, go over the opening with a primer that improves adhesion.

Preparing the window opening

A wooden block is attached along the perimeter of the opening, but already near the frame. Choose the thickness depending on the distance: it should almost fit the frame. One side of the block must be worked with a plane, making an inclination. The angle of inclination of this face equal to angle slope installation. You can saw it off, but it’s more difficult to make it straight unless you have a circular saw with an adjustable angle.

We make a slope on one of the faces of the block

We screw the treated block to the walls around the perimeter of the opening. The mounting method depends on the wall material. If the wall is brick, you can try using self-tapping screws; in a concrete wall, you need to install dowels.

You buy a starting profile in the store, install it with the long side to the block, and fasten it. It is more convenient and faster to fix it to the bar with staples from a construction stapler; if you don’t have one, you can use small nails or self-tapping screws with flat heads.

We attach the starting profile

When choosing a starting profile, choose a dense one. It’s more expensive, but you only need three meters per window, maybe a little more. A dense profile will hold the plastic well, a soft one will bend and the appearance will be ugly. One more point - when installing the profile, press it as tightly as possible to the frame so that there are either no gaps at all or they are minimal.

At the top, when joining vertical and horizontal profiles, you need to be especially careful and cut them exactly at an angle of 45°. If there are small gaps, they can be sealed with acrylic.

Installed starting profile

Using this technology, it is more convenient to start installing reservoir slopes from the sidewalls. Insert the panel into the fixed starting profile. It is also better to take them from expensive and dense ones, with a thick layer of plastic. If you install cheap ones (ceiling), then the front wall is thin, and in bright light the jumpers will be visible. In addition, such plastic can be pressed even with your finger.

We insert a plastic panel into the profile

The width of the plastic panel should be larger than the slope. If the width of one is not enough, two are joined. But then at the junction you will need an additional vertical strip to which the first strip will be attached.

The panel inserted into the profile is usually longer than the opening. Holding it with your hand, mark the line of the opening. After removing, cut along the marked line.

Cut to size

We install the panel again, move it a little away from the wall and fill it with foam, trying to fill it without gaps, but without excess. To make this happen, we start from the far bottom corner - draw from bottom to top near the nailed bar. By the time we reached the top, the foam below had expanded a little. Draw a line with foam again, but closer to the edge. The closer to the outer edge, the less foam is required - after all, the panel is installed under a slope, so make the paths thinner. Having reached the middle, make a snake on the rest of the surface and press the panel the way it should stand. Align and check. Secure to the wall with masking tape. The second part and then the upper part are installed in the same way. It can also be cut out using a paper template, and the edges can be adjusted to a perfect (or almost) match using sandpaper.

Installed plastic window slopes

Having installed all parts of the slope and secured with masking tape, leave until complete polymerization. Then, in order not to putty the gaps between the slope and the wall, a white plastic corner is glued onto liquid nails. The main task is to cut exactly in the corners. It is easy to glue: apply a thin strip of glue to both shelves of the corner, press it, moving your hand along it, hold it for a couple of minutes. This is how they are installed around the entire perimeter, then, before the glue dries, they are also glued with masking tape and left.

Installed corners along the perimeter of the slope

After a day, we remove the tape, the plastic slopes are ready.

This is what a window with installed plastic slopes looks like

If there are gaps somewhere, they are sealed with acrylic, as described above. Don't use silicone. In the light it quickly turns yellow. In a year or two your windows will look terrible. Look for white acrylic sealant and mask it with it.

Plastic slopes on windows: do-it-yourself installation, two methods

If you have installed PVC windows, it makes sense to make slopes from plastic. They will have the same performance characteristics, thermal expansion, the appearance will be logical, the quality will be excellent.

Guide to installing plastic window slopes

After the window is installed, all that remains is to finish the slopes of the plastic windows. PVC elements perform not only decorative, but also important protective functions. You can install plastic slopes on windows with your own hands. How to install plastic slopes will be described below.

What are they needed for

The installation of plastic finishing is the most common way to improve the space of a window opening. PVC slopes have a pleasant glossy surface and are combined with the window profile material. Plastic panels protect the installation seam from exposure to sunlight and moisture.

Finishing the slopes after installing the window is done using plastic

The mounting foam, with which the window system is fixed in the opening, is a water-repellent material. But if it is not protected from direct sunlight, it will begin to deteriorate and moisture will freely begin to penetrate into its pores, destroying it from the inside. Therefore, slopes for plastic windows need to be installed as soon as possible after installing the window..

Properties of plastic slopes

Slopes for plastic windows can be made of two types of material - these can be window slopes made of PVC panels or sandwich panels.

The slope serves to protect the polyurethane foam from destruction

For both types plastic panels characterized by general positive qualities:

• long service life;
• plastic slopes for windows have a decorative appearance and are combined with the material from which the window system is made;
• finishing window slopes plastic inside allows you to reliably protect the mounting foam from environmental influences;
• installation of plastic slopes is possible for finishing arched openings, since flexible PVC casing can be used;
• you can install PVC panels with your own hands, without professional skills and special expensive equipment;
• plastic panels for slopes can be cut with a hacksaw for metal, but this must be done carefully, without exerting force, so that the PVC panel does not crack;
• Do-it-yourself installation of plastic windows occurs quickly and without the formation of serious pollution and construction waste;
• PVC panels are easy to care for - just wipe them occasionally with a cloth soaked in a soapy solution;
• they have low thermal conductivity;
• The plastic window element is highly moisture resistant;
• Finishing the slopes of plastic windows will reliably protect them from freezing.

Products made from PVC panels

Before installing plastic slopes with your own hands, you need to familiarize yourself with the qualities of the material used to make them. One of them could be a PVC panel.

Description of material

Another name for this material is ceiling panels. They are made from polyvinyl chloride.

They consist of two plastic plates with stiffening ribs inside. Some models are provided with locking connections at the ends.

Panels may have different sizes, but during installation they will still have to be cut to the required dimensions. Despite the fact that the panels can have a length of 3 and 6 meters, you should purchase 6-meter products. The thickness of the panels varies from 0.5 to 1.2 cm. The type of products can also be different: panels, slats or PVC sheets.

They also purchase components for plastic panels. The kit should include fasteners and plastic elements. Their description is presented in the figure below.

Accessories for plastic panels

One of the advantages of any plastic panels is their wide range of colors. Colored PVC slopes can be matched to any interior.

The color of the finishing plastic can be matched to any interior

The interior decoration will look original when covering the window openings with plastic panels with an image or imitation of any natural or artificial material. When the windows are colored or brown, painted products can be used. It is important that in this case the window fittings are combined with them.

PVC panels can imitate a wooden surface

The panels can be plain, laminated, varnished, or have a printed pattern or image applied using thermal printing on their surface. Installing plastic slopes will give the windows a neat, decorative appearance.

Positive qualities of the material

High-quality finishing of slopes with plastic with your own hands is obtained thanks to the properties of the ceiling panels.

• the material is non-toxic;
• have high moisture resistance;
• they are easy to install and maintain;
• have little weight, so they do not create a load on the base;
• plastic is a non-flammable material, but when melted it emits toxic, acrid smoke;

products are resistant to temperature changes;

• have frost resistance;
• create an ideal, flat, rigidly fixed surface;
• have a modern look and are suitable for any interior;
• the honeycomb structure provides reliable noise insulation;
• do not accumulate static electricity on their surface;
• panels are resistant to household chemicals.

How to install plastic slopes on windows with your own hands step by step is shown below. Before you start finishing the slopes with panels, you need to take measurements. The inner sides are measured twice - at the window and at the wall.

• installation of plastic slopes on windows begins with removing the mounting foam that has gone beyond the perimeter seam window frame. To do this you need to use a sharp construction knife;

Sandwich panel products

Do-it-yourself installation of plastic slopes can be done using multilayer material coated on both sides with decorative plastic. By installing plastic slopes with your own hands using sandwich panels, you don’t have to provide additional thermal insulation.

Sandwich panels have high thermal insulation properties

Installation of PVC slopes when using this material occurs quickly and with a minimum amount of debris. The use of slopes made of PVC panels of this type provides protection for windows from freezing.

Sandwich panels have the following characteristics:

• PVC provides reliable heat and sound insulation;
• finishing window slopes with this material increases the energy efficiency of the window system as a whole;
• if you correctly make slopes from panels with your own hands, then the window opening will acquire a neat appearance;
• finishing windows with plastic with your own hands is done quickly and efficiently;
• Even an untrained person can make slopes from plastic with insulation.

Construction and installation of slopes for plastic windows

What types of slopes are there?

Over the past two decades, the technology for installing plastic windows has been refined to the smallest detail. The advantage of plastic over other materials has long been beyond doubt. In this case, special attention is paid to the installation of slopes. Slopes for plastic windows are a mandatory element. According to established terminology, slopes are the surface of the walls near the plastic frame - top, bottom and sides. Depending on their location, they are external and internal. Special attention is paid to the finishing of internal slopes, since they carry a functional and aesthetic load.

You need to know that heat leaks through the junction of the window frame and the wall. Polyurethane foam, which is used when installing a window, if not protected from external influences, accumulates moisture and collapses. Others follow Negative consequences- fogging of the glass unit, the appearance of mold, deterioration of sound insulation. Slopes for windows perform a complex function - protection and decoration. Their installation is ordered simultaneously with the installation of the window, or they carry out this work independently.

In practice, slopes made of plastic are used for plastic windows. various materials. Including:

• from sand-cement mortar;
• from plasterboard;
• made of plastic;
• from foam plastic;
• from a sandwich panel;
• from decorative materials.

When choosing one option or another, you need to take into account the peculiarities of the structure in which the work is being carried out. It’s one thing when a window is installed in a new, brick or panel building that has just been built. In this case, no preparatory work is required. Others are when a plastic window is installed to replace a wooden frame in a house that is many years old.

As a rule, the dimensions of an old window are larger than a new plastic one. Before installation, it is necessary to remove any remaining plaster and insulation from the window opening. Cut down the sagging of old concrete. There should not be a trace left of the old slopes. The plastic window is attached to the wall using brackets, and the openings formed around the perimeter are filled with polyurethane foam. In a wooden house, the same list of works is performed. But slopes made of plaster mortar are not used in such houses.

Installation of slopes on plastic windows

The quality of the window slopes will determine how comfortable the atmosphere will be in the room. Plus, windows are an element of interior design. When choosing a specific material, you need to prepare materials, tools and all components. In this case, the installation of slopes on plastic windows will be done efficiently.

Plastering and painting

The easiest way to finish the slopes of plastic windows is to wipe the surface with a sand-cement mortar for plaster. If the apartment owner has skills in finishing work, then he will not face any difficulties. Before finishing the slopes, the walls in the room must be plastered. As a beacon, you need to attach it around the perimeter of the window opening wooden slats. The top rail must be strictly horizontal and flush with the slope plane. The horizontal position is checked using a simple carpenter's spirit level.

The side slats are mounted on the wall flush with the slope plane and aligned vertically. You can prepare the solution from a dry mixture that is sold in the store. building materials. Preparation instructions are included on the package. If the mixture contains gypsum, then it must be worked out quickly, within half an hour. When you have to prepare a solution from sand and cement, you need to mix it in a ratio of 3/2. Three shares of cement and two parts of sand. The solution should have the consistency of thick sour cream.

Wet finishing processes require time and strict adherence to technology. The next layer of plaster is applied only after the previous one has dried. At the same time, you need to be aware that during final drying, cracks may form on the surface. They need to be puttied and then the slopes covered with a primer. Paint is applied to the primed surface, and the window opening gets a completed look. It should be noted that the installation of such slopes does not improve the thermal insulation of the window unit. In winter, drizzle can form on the windows.

Finishing slopes with plasterboard

Installing plasterboard slopes is much faster. It is important to emphasize that this material can be used in rooms with low humidity. Moisture-resistant varieties of this material are commercially available. When installing them, you can use foam or mineral wool insulation. The installation of plasterboard slopes also requires certain skills and dexterity. The design of many window blocks has a special profile around the perimeter, which is designed to fix the finishing panel.

If such a profile is not available, then an L-shaped plastic corner should be secured to the edges of the window block with self-tapping screws. Then blanks are cut from a sheet of plasterboard according to pre-prepared sizes. There should be three of them - one top and two sides. The profile is filled with sealant, after which the slope panel is inserted into it. A layer of glue is applied to the opposite edge of the panel, with which it is attached to the wall. The connection must be smooth and strictly vertical.

The volume that forms between the wall and the panel is filled with insulation. This can be mineral wool or a foam plate. The panel is fixed in the same way on the other side. Then the top panel is attached. For reliability, the panels are fixed with dowels with nails along the perimeter every 35-40 cm.

To complete the work, you need to install corners on the cuts for strength. Irregularities are puttied and the surface is polished.

Finishing slopes with plastic

Plastic slopes are considered the most technologically advanced. In color and texture, they harmonize better than others with the window block. Any man whose hands grow out of them can install them. the right place. First you need to prepare the slope surfaces. Remove excess foam and other foreign objects. Then a starting profile is attached around the perimeter of the window block. Fastening is carried out using self-tapping screws at intervals of 20 cm. After this, a sheathing made of timber with a cross-section of 20x40 mm is installed.

The sheathing is attached to the corner of the slope with dowels every 30-40 cm. After this, the top panel is mounted. To do this, one of its edges is inserted into the starting profile, and the other is fastened with self-tapping screws to the sheathing. The side panels are installed in the same way. The next step is installing the platband. F-profile PVC is used as a platband.

When installing, you need to ensure that the platband fits tightly to the panel. At the end of the installation, it is necessary to treat all joints with white sealant to prevent dust and moisture from getting into them.

Foam slopes

The technology for installing polystyrene foam window slopes is practically no different from how slopes made from other materials are installed. The positive parameters of a foam plastic slope include its long period of operation, high degree thermal insulation, manufacturability in processing. Finishing windows with foam plastic begins with cutting the material. The parts are glued together in pairs. To enhance the strength of the foam, the blanks are reinforced with fiberglass.

The sequence of operations includes: priming the surface, applying glue to it, installing the slope elements in their place. The installation accuracy is controlled vertically and horizontally using a spirit level. The joints between the parts must be glued. The next step is to apply putty to the surface of the slope. Then the surface of the foam is primed and painted. That's it, the slopes are installed.

Conclusion

Slopes for plastic windows can be finished with sandwich panels. These panels are made of plastic and have their own operational parameters close to the material from which the windows are made. Structurally, plastic sandwiches are designed in such a way that they have increased strength and rigidity compared to plastic sheets. The structure and sequence of installation of such slopes are exactly the same as when using drywall.

Among the decorative materials used for finishing plastic windows are noble types of wood, artificial and natural. finishing stone. Windows are not often decorated with such materials. Oak, hornbeam, cedar have high cost. Exactly the same as artificial marble or granite. They are used to decorate plastic windows according to individual projects. The installation of such decorations requires high skill and is used very rarely in typical apartments.

DIY slopes for plastic windows

Slopes for plastic windows require certain qualifications and skills from the master. Window finishing is made from various materials.

Hello!

Have you looked at my page again to learn something new in the field of construction finishing works?

We will talk about the process that is a consequence and an integral part of the work associated with the installation of plastic windows - finishing the internal slopes.

I hope that for those who decide to independently install and finish the slopes, this article will become practical guide for this type of construction work.

How to make internal window slopes

To learn how to design internal slopes yourself, you first need to decide what slopes you will make.

It is clear that:

• their plane should be smooth, without cracks;
• the side and top lines of the junction with the wall are straight;
• from all three sides the slope should cover the window frame with the same grip;
• the angles of dawn of the side slopes must be identical to each other.

These are common truths known to everyone. Well, we’ll talk about how to ensure that the slopes meet these requirements a little later - after we decide what building material will form their basis.

Meanwhile, choosing the material from which the slope in your house will be made is not such a simple question as it seems, so we will consider it in more detail.

What material

What is the further arrangement? window opening, after it was installed in this opening window unit? That's right, what follows is the finishing of the slopes of this opening with one of the building materials, the list of which begins with classic plaster and ends with wooden lining.

You need to choose the slope covering material based on the purpose of the room in which it is located. window hole.

Let's look at some of the options:

• the interior of the room is stylized with natural wood trim, and the owner wants to emphasize this direction in all details, even in the arrangement of the window opening. In this case, MDF panels, PVC panels, laminate, laminated fiberboard, natural wooden lining. Naturally, MDF, PVC, fiberboard and laminate must have a wood imitation. It is worth noting that in order to avoid sharp dissonance with the slopes, the plastic window must also be laminated to match the texture and color of the wood;
• the room has a style that corresponds to the concept of “minimalism”, where nothing should be conspicuous, including window openings. In this option, the best choice would be classic plastered, puttied and painted slopes. If the window frame of a plastic window is standard white, then it is better to paint the slopes matte white;
• a window opening is located in a room where the window is constantly covered with a curtain or curtain. If the window is out of sight and its aesthetic component does not play a role in the decoration of the room, the slopes can quickly and easily be decorated with a plastic panel with a color similar to the color of the window frame;
• window installed in technical room or in the bathroom. As a rule, the decoration of the walls of these rooms is of a specific nature and, in most cases, it is finished with tiles, sometimes (in the bathroom) with mosaics. The same materials (only after plastering) can be transferred to window slopes - it will be both stylish and practical.

Besides, To decorate window openings, you can use plasterboard, penoplex and even metal. In what cases these types of finishes are used, I will tell you when we get closer to specific cases of their installation on slopes.

As you can see, there is a choice of materials for constructing slopes, and you have to make it.

Main types of installation of internal window slopes for plastic windows

The problem of what slopes will be made after the plastic windows are installed must be solved even before installing these windows.

Very often, the organization that installs window blocks can also provide services for finishing slopes. If you want to see the slopes around installed windows, then the easiest way will be to find out whether a given organization has a similar service in its arsenal and what finishing options they can offer you.

Most often, installers of plastic windows offer to install slopes from PVC panels - it does not take much time and is quite economically feasible.

How to finish slopes, watch the video:

Made from PVC panels

If the distance from the frame to the plane of the inner wall is not very large (up to 37 cm), then it can be covered with one plastic panel. In houses with substantial wall thickness and, accordingly, a large window opening depth, two panels can be joined, which, of course, is not very good, because their joint is quite noticeable.

P The PVC panels from which the slope is made must be mounted on a pre-arranged frame. Often, installers neglect this condition, and the entire installation consists of inserting the panel into an outer F-shaped strip fixed along the edge of the slope and an initial profile fixed to the window frame.

Such negligence threatens that when pressing on the panel, it may simply fall under the slats, and then putting it in its place will not be so easy.

The appearance of slopes made of plastic is, as they say, “not for everyone.”

Some owners of plastic slopes are simply delighted - this finish does not require special care, no marks remain on it, it merges with the window frame, and is also perfectly even and smooth.

And some people notice that after installing the plastic on the slopes, when the sun's rays hit it, an unpleasant odor appears in the room. The plastic itself begins to turn yellow from exposure to the sun over time, and it looks too much like an artificial material.

For those who do not like PVC slopes, the main complaint expressed is the poor quality of the panels. This issue can be resolved by choosing certified products, technical specifications which states that it is intended for use in different weather conditions.

From plaster composition

I’ll say right away that plaster slopes are a bad solution for finishing openings in a wooden house.

In principle, they can be made on wooden slopes: install a plaster mesh and apply a plaster composition to it. But the whole question is how long will this slope last before it begins to become covered with cracks, because the tree begins to “play”? I'm sure it won't be long.

For this reason slopes made of plaster are a privilege of houses in which window openings are made of brick and concrete.

Finishing slopes with plaster is considered not so much labor-intensive as a lengthy process.

First you need to prime the base and let it dry. Then you should spray (for better adhesion) from plaster composition, if we are dealing with a slope device in a panel or monolithic house, and let the composition dry again.

Depending on the thickness of the layer that needs to be applied to the slope, the plaster has to be applied several times, and before each subsequent application the previous layer must be completely dry.

After the applied layers have completely dried, the slope is again primed and puttied, at least twice.

Then the dried putty is sanded with sandpaper to bring the treated surface to perfect condition, and primed again.

The last stage is applying two layers of paint.

Have you noticed how many times you need to stop before starting the next stage of finishing?

Many times, and all this takes time, which, as you know, is money for any builder. Therefore, do not be surprised when, in order to make a slope made of plaster, you are asked for an amount three to four times higher than the cost of installing a plastic slope on the same window.

If you are promised to make a slope of plaster in a day or two, then be prepared for the fact that its surface will soon be covered with a network of cracks, and this will not be the worst thing.

The main trouble that can happen to a surface that is plastered in violation of technology is its complete separation from the base. So think about what’s better: wait patiently until each plaster layer it will dry out and shrink, or do everything quickly and at one not at all wonderful moment you will see pieces of plaster falling off the upper slope on the windowsill.

By the way, since we remembered the upper slope, I can say that often experienced builders, instead of throwing plaster on the upper slope (due to the particular complexity of this work), take the path of least resistance and install a sheet of moisture-resistant drywall on it.

The result is a combined type of finishing: plaster on the vertical sides, and plasterboard on top.

This is how we smoothly approached the next popular material used for finishing slopes - dry plaster or sheet plasterboard.

From plasterboard

There are two ways to fix drywall on the surface of a window opening:

• stick on a special adhesive composition;
• screw onto a metal or wooden frame.

Gluing is a simpler and more accessible method.

The first blank for the upper slope is cut from a sheet of moisture-resistant plasterboard (necessarily moisture-resistant, since the slope is a zone of high humidity). Its length should be equal to the distance between the side slopes, and its width should be a couple of centimeters greater than the distance from the window frame to the plane of the wall.

It is desirable that the side of the workpiece that touches the frame have a raw “factory” joint. It is easier to putty, and it is less susceptible to mechanical damage than the cut edge.

After making sure that the workpiece is suitable in size, you need to prepare one board slightly shorter than the length of the workpiece, and two more supports - equal in length to the distance from the window sill to the upper slope.

Several beads of adhesive are applied to the inside of the workpiece, after which it is fixed to the top of the opening using a board supported by supports.

Blanks for side slopes are cut according to the same pattern: length from the window sill to the upper slope; width from frame to wall with a margin of a couple of centimeters.

After mandatory fitting, it is necessary to apply the same adhesive composition to the inner surface and ensure contact with the side wall of the window opening.

It should be noted that immediately after contact with the surface of the opening, the workpiece must be adjusted to the level. To do this, you need to attach a strip level to their surfaces in two places - near the frame and in the area of ​​\u200b\u200bthe junction with the wall of the room.

After the drywall is glued, you can cut off its protruding part along the plane of the wall and begin puttying and painting.

Installing drywall on a slope using a frame is a relatively difficult task. In this case, much depends on what space is allocated for installation and to what surface the frame should be attached.

Non-traditional materials

Slopes interior space- this is not just the surface between the window frame and the wall of the room in which the window opening is located. Slopes are, first of all, a structural element of the entire building., which, like a window unit, is endowed with certain technical functions and is responsible for the atmosphere in a particular room, and, consequently, for the comfort of living.

If slopes in a house are not part of the decorative design, but only fully perform their heat and moisture protection functions, then, as a rule, no one notices them. But as soon as mold or mildew appears on the wall where the window opening is located, the search for the cause of this problem immediately begins.

Freezing of slopes, peeling of paint from their plastered surface, the appearance of condensation on a PVC slope, peeling of paper from the surface of drywall - these and other defects force builders to look for other, giving top scores approaches to finishing the internal surfaces of window openings.

Three-layer panels

Sandwich panels made of plastic and foam plastic are designed for finishing and insulating premises. We are accustomed to the fact that this material is used for the construction of insulated buildings, that it is large in size and has a solid thickness.

But competition forces manufacturers of building materials to quickly satisfy all the needs of the rapidly growing construction market, so the market special sandwich panels appeared for finishing indoor slopes.

Externally, a slope made from a sandwich is difficult to distinguish from one made from a PVC panel - it is also white and has the same plastic surface in appearance. But there are significant differences in quality characteristics.

Sandwich panel is an excellent thermal insulation material.

A heat insulator (foam plastic) is glued between its two plastic sheets, which, in addition to preserving heat, also serves as a good barrier to sound waves.

Sandwich, unlike plastic, is a fairly hard material, and it is quite difficult to damage it.

The thickness of the sandwich panel is the same as that of plastic, so it is mounted according to the same principle - using an F-shaped initial and corner profile.

So the appearance of the slopes remains virtually unchanged and does not depend on whether a sandwich panel is installed on it or a PVC panel is fixed.

Penoplex

Extruded polystyrene foam is not a very common material for finishing slopes, however, it can also be used for these purposes by experienced finishers.

This material can be used in cases where it is required:

• make the slope as warm as possible;
• fill too large a distance from the outer plane of the future slope to the plane of the opening;
• install sufficiently moisture-resistant material on the slope.

The thickness (from 20mm and above), as well as sufficient rigidity and moisture resistance of penoplex, make it easy to perform these three tasks.

Internal slopes made of penoplex are installed according to the same scheme as slopes made of plasterboard– can be glued or attached to the frame.

The only difference in the finishing of these two materials is that the surface of the drywall is puttied without additional conditions, and on the penoplex, due to the rigidity of its surface, before applying the putty, you need to glue the painting fiberglass - “cobweb”.

Decorative rock

There are many ways to create the desired atmosphere in a single room. Finishing slopes is one of them.

For example, if, according to the designer’s idea, there is a wall or part of it inside the room, trimmed with decorative stone, then the appearance of this finishing option on the window slopes will be not only a logical, but also an original continuation of the interior solution.

For a bathroom, a natural solution would be to continue the wall pattern, transferred to the plane of the slopes. Often in bathrooms and technical rooms instead of a plastic window sill, the same finishing (tiles or mosaics) that is on the walls and slopes is installed on the lower part of the opening.

Moreover, nothing special needs to be done in preparing the surface for this type of finishing. Tiles, mosaics, and decorative stones can be glued to a plastered or plasterboard-covered surface.

Technical aspects of installing plastic slopes

The installation of a window block is necessarily followed by the finishing of the window opening, that is, the planes adjacent to the window of the upper and side slopes, as well as the installation of a window sill board.

Without these elements of interior decoration, the window will not fully cope with the functions that are included in its technical characteristics, and, in general, will not be able to look like a finished product.

For one very important point, preceding the installation of slopes, I would like to draw your attention separately.

Particular attention is paid to preparing the surface of the window opening for finishing.

Even if the slope itself, made, for example, from sandwich panels or polystyrene foam, is a heat insulator, then the connection of the window frame to the plane of the slope must still be made using a special technology.

The principle of this technology has long been formulated and confirmed by many years of experience. It consists of the following: the vapor permeability of all adjoining layers must have a certain order.

From the inside, the barrier should be the most gas-vapour-tight, and its density should gradually decrease as it approaches the outer part of the window opening. This is done so that even that minimal moisture, which in any case has the opportunity to penetrate under the slope, finds its way out.

If this rule is observed, a well-arranged connection of the window to the frame looks like this:

• on the room side, the first (most impermeable) layer should consist of butyl rubber tape, for a greater reflective effect, coated with aluminum plating. Sometimes, instead of a special tape, the junction is coated with mastic or silicone, but an effect equal to that obtained when using butyl rubber tape can only be obtained if the mastic layer is at least 6 mm;
• the second layer is ordinary polyurethane foam, which is no longer a good gas-vapor-tight composition, but due to its qualities it can restrain moisture and (which it is especially good at) sound waves;
• the third, outer layer, is a pre-compressed self-expanding tape - PSUL - after gluing it to the frame. It protects the mounting foam from exposure to sunlight, allows air to pass through well, but prevents the penetration of precipitation.

If the connection is made according to all the rules, then you can start constructing the frame. To do this, you need to stock up on a 60x27 metal wall profile, which is usually used to construct a supporting frame for drywall.

First, a piece of profile is cut out in length equal to the distance from the frame to the edge of the slope. Then a cutout is made on one side of it, which is bent and, using short self-tapping screws with a press washer, attached to the very edge of the window frame so that it is subsequently completely covered by the initial strip.

The opposite side of the profile, after bending the shelves, is nailed to the outer edge of the opening with dowel nails.

All profiles placed on the same plane (they must be installed at a distance of 30 cm from each other and without fail directly above the window sill and in the corners at the joints of the panels) should be aligned along a stretched cord.

Another technical point you can use it if you have to do the finishing of the slopes yourself. And also, knowledge of this nuance will not be superfluous when you have to supervise the work of finishers.

I want to tell you how to properly make an abutment at the junction of the slope and the window frame. For slopes made of plastic panels, penoplex and sandwich panels, what I will say is irrelevant, but plastered or plasterboard surfaces must have this structural element.

Many people drew attention to the fact that when sharp blows sash against the window frame, putty or even pieces of plaster in the place where the slope covers the frame gradually begin to crack and fall off.

Vibration plays the main negative role in the appearance of this defect. plastic surface frame profile. No matter how well the plaster or drywall holds up, the putty covering the joint will inevitably crumble due to mechanical stress.

You can avoid this kind of trouble before puttying, for which you need to clean the joint and fill it with silicone - it will dampen vibration and also reliably close the junction from the passage of moisture and air.

If you want the silicone gasket to be unobtrusive and the same color as the slope, then acrylic silicone is best suited for these purposes, which may have different colors, and even, if necessary, its surface can be painted in any desired shade.

Slopes as an element of interior decoration

According to one dictionary, the word “slope” means a sloping slope or inclined surface.

It is this definition that is most suitable for those planes that we call window slopes. If the plane of the slopes (no matter the side or top) is in a strictly perpendicular position to the window frame, then such a slope is considered to be installed in violation of standard requirements.

One of the standards considered mandatory in the construction of window slopes states that each slope plane must have a certain rotation relative to the window frame, called the “dawn angle.”

The angle of rise of the slope plane must be greater than 90 0 relative to the plane of the window block installed in the opening.

All slopes, both side and top, as a rule, should have the same dawn angle, but in practice this rule cannot always be implemented. More often you can find an option when the upper slope is turned in relation to the frame, but differs in the angle of dawn from the side slopes, which should have exactly the same dawn among themselves.

There are no clearly defined parameters limiting the required dawn angle. It all depends on how much the opening will allow the slope to unfold, and on how the slopes appear to the owner of the house in which they are settling.

It’s impossible to check the angle of dawn on an already installed slope or, if necessary, calculate it yourself special labor. For this procedure you do not need special protractors; a regular ruler and a regular square are enough.

You need to place a square on the edge of the window frame along the edge itself so that you can use a ruler to measure the distance to the junction of the slope with the wall of the room on which the window opening is located.

The resulting distance must be transferred to the opposite slope by placing the square at a point symmetrical to the one used to measure on the previous side.

In the same way, you can make the same angle of dawn for the upper slope by installing a square on the edge of the upper crossbar of the frame and transferring the resulting distance to the junction of the upper slope with the wall of the room.

Watch the video about the advantages of slopes made of sandwich panels:

Disadvantages and advantages of PVC slopes

First of all, it is worth noting that all the disadvantages of plastic slopes lie in the quality of the PVC panels themselves and in poor quality preparation of the junction of the window and the walls of the opening.

Only the quality of the plastic influences whether the plastic will change color during use. Sometimes plastic, being completely white when installed, loses its color over time or, when the temperature increases (for example, under the influence of ultraviolet rays), it emits an unpleasant odor.

I think many will figure out on their own how to deal with this drawback without me - you need to check the quality characteristics of the PVC panel before installing it in the window opening.

As for poor-quality preparation, then, if you decide to install the slopes yourself, you must comply with the conditions that I have already written about in this article.

And if the slopes in your house are being made by a construction team, then careful and total control is necessary during the work.

Only after a control check of the arrangement of the junctions of the frame and the slope can the builders be given the go-ahead to proceed with the work.

We talked about the disadvantages, now let's move on to the advantages.

Let's start with the main advantage: the slope, made of plastic, is a collapsible structure.

Disassembling a structure based on a frame made of a metal profile or wooden blocks is not particularly difficult.

And if the builders took the path of least resistance (to put it simply, they cheated) and, simply, inserted plastic into the fixed planks, then by simply pressing on the panel, you can easily see everything that is under it, and, if necessary, correct the shortcomings made during the construction junction of frame and window.

The next thing to note is ease of care for the plastic surface. It is difficult to get dirty, but even if such a nuisance occurs, cleaning the plastic is as easy as shelling pears.

It can be said that a plastic slope is the most suitable continuation of the finishing surrounding the plastic window. And even for slopes wooden house or rooms with a “wood” finish, you can quite easily select plastic panels that match the color and texture of the material with which the room is decorated.

PVC panels have another clear advantage over other materials used for constructing window slopes - minimum time for their installation.

In addition, when installing plastic slopes in the room where work is carried out, there is much less noise and dust. This is very important in cases where the owners do not plan to do complete renovation rooms, but they are just going to replace the window and install slopes.

Some people who have installed PVC slopes in their apartment note one drawback that, in their opinion, is striking.

We are talking about an F-shaped strip, or more precisely, about that part of it that covers the edge of the plastic at the junction with the wall. It is noted that this part of the bar is too wide (from 3 to 6 cm) and looks interior wall The premises are not very aesthetically pleasing.

I can tell you how to get rid of this, so to speak, shortcoming.

It is enough to just lightly treat the protruding surface of the plank with fine sandpaper, then prime it, and then you can apply anything to it - from wallpaper to acrylic paints.

Speaking about the technical and quality aspects of plastic slopes, I forgot to say that for many, the decisive argument in their favor is the cost of materials and installation work. Here, of course, there are no competitors to plastic.

The material for slopes made of plaster is also not expensive in itself, but the installation work will require considerable investment (I have already considered this issue).

Materials

So, the window block has taken its place in the window opening, the mounting foam has dried, the window connections are hydro- and gas-insulated, which means you can begin installing the slopes. What will it take? Let's start with the materials.

If future slopes will be made of plastic panels, then you need to prepare:

• PVC panels, their usual length is 3m.p. Since the panels on the slopes do not meet along the length, this means that a whole piece is needed for each slope. On standard window 1400x1300mm will require two panels. It is better if there are several windows. In this case, it is possible to organize waste-free production. Yes, and don’t forget to find panels that fit the width of the slope;
• the strips that will serve as the edging and will hold the panel are F-shaped, starting and connecting the inner corner of the profile. These profiles do not have to be installed in whole pieces over long sections; with careful trimming, their joints are almost invisible;
• for the frame construction it is advisable to use ordinary metallic profile 60x27mm, which is used when installing drywall;
• self-tapping screws with press washer 4.2x13. The head of these screws is very flat and will not interfere with the plastic. For a standard window you need about 50-70 such screws;
• dowel-nails 6x60 for nailing a metal profile to the wall;
• a silicone balloon, preferably white.

We have collected a set of materials necessary for constructing a slope. This means that it’s time to take care of the availability of tools, without which it is impossible to assemble the frame and install plastic on it.

Tools required for installing plastic slopes

From construction tools we will need:

• tape measure, the length of which is at least 2 m;
• strip level from 60 to 120 cm long;
• screwdriver for tightening screws;
• hammer drill for installing dowel-nails;
• drill 6x100mm;
• a set of attachments for tightening screws;
• hammer;
• a hacksaw with a fine tooth or a construction knife for cutting plastic panels;
• metal scissors;
• silicone gun.

When everything necessary for installing slopes lies next to the window opening, you can begin to work. I have already described the installation process in detail in this article.

Let me just remind you that the initial profile is placed at the junction of the panel with the window frame and at the place where the panel rests on the window sill.

The internal corner profile connects the PVC panels to each other at their corner joints.

The F-shaped profile is used for fastening outside PVC panels, as well as in order to hide its connection to the wall of the interior.

Some builders foam the space under the plastic for better thermal insulation of the slope. It seems to me that such insulation only gives moral satisfaction to those who use this method, and has no practical benefit.

I'll explain why.

In order for the polyurethane foam to fulfill its function, it must fill a space that is closed on at least two sides. A simple, unrestricted application of foam to the wall will be uneven and, therefore, useless. If you try to apply foam between the panel installed on the slope and the wall, the result will be disastrous, since the foam will inevitably squeeze out the plastic.

If, in addition to a properly arranged junction, you want to additionally insulate the space under the panel, then you can go the other way. To do this you will need polystyrene foam and glue to fix it.

The foam is selected in thickness so as not to interfere with the plastic panel, applied to the wall of the opening and glued.

This internal insulation slope and reliably, and does not cause any trouble during the work.

You can take note of one more nuance. Before installing the plastic panel, it is advisable to cut off its mounting tenon, then the front part will go deeper into the initial profile and, therefore, will be more securely fixed to it.

Which material is better for slopes?

This formulation of the question is not entirely correct; it is better to reformulate it differently: in which room is it best to install a certain type of slopes. In this case, you can give the most correct answer.

If the room is decorated with wood

For a room in which the main finishing element is natural wood or its imitation, the slopes can also be made from natural wood - lining, or from plastic laminated to look like wood, or from fibreboard also covered with lamination.

What's good this type slope finishing? First of all, a modest expenditure of money if a plastic panel is taken as the basis for the finishing material.

The only thing I would like to note is that wood and laminated fiberboard are still afraid of high humidity.

Therefore, if the only question is that the appearance of the slopes continues the wooden theme of the room, then it is still better to install plastic under the tree. This is all the more simple because the choice of options for plastic panels on the construction market today, as they say, is for every taste and color.

Standard solution to the problem of installing slopes

Slopes made of plaster, puttied and painted are pure classics, and like any classics, they can suit any interior design, except for wood finishes.

The advantage of plastered slopes is their solidity and reliability, as well as their ability to absorb and release moisture. In other words, they can breathe.

However, plaster has many more disadvantages:

• Before plastering, you need to thoroughly insulate the walls of the openings. If this is not done with special care, the plaster can freeze through, since it itself is not a heat-protective composition;
• On the plastered slope, the final finishing layer is usually acrylic paint, which has to be renewed periodically;
• the process of installing slopes takes a lot of time (of course, if all operations are carried out according to technology);
• the cost of installing a plastered slope is significantly higher than the cost of installation using methods using other materials.

Non-standard approach

A new type of finishing of slopes is the installation of a cork covering on their surface.

Although cork is a material that imitates a wooden surface, in my opinion, on slopes it looks like a completely independent finishing element.

The basis for cork can be anything that has a smooth and even surface: plaster, drywall. The cork can be glued to the plastic using a special adhesive composition.

Every home has rooms that can be described as special or intended for specific purposes. These include a swimming pool, boiler room, bathroom, laundry.

Since the premises are defined as “special”, the approach to finishing their slopes can be highly specialized.

What are the requirements for finishing window openings in such premises? They must be reliable, not absorb moisture, repairable and not lose their appearance due to frequent washing.

Only ceramic tiles glued to a plastered base are suitable for the required conditions. You can, of course, glue the tiles onto drywall fixed to the frame, but then this slope will not fit the definition of “repairable”, because broken or cracked tiles can only be removed together with the base - drywall.

Finishing the slopes using plasterboard installed on the frame, puttied and painted is also one of the ways to improve the appearance of the window opening.

Why do I classify drywall installation as a non-standard method of finishing slopes? Because this method should be used only when the slopes are not located in an area of ​​high humidity.

And you need to remember that only moisture-resistant drywall can be used for finishing slopes.

Although its use does not guarantee complete moisture protection, as, for example, in the case of finishing slopes with PVC panels.

Popular method

The logic that guides those who decide to decorate the window openings of their apartment with plastic is quite simple: if the window is made of PVC, then why not make the slopes from the same material?

And the correctness of this logic begins to be confirmed from the very first moment when builders begin work on constructing slopes.

In the event that the finishing of the slopes takes place in a living room, where no other repair work is being carried out other than replacing a window, this method is indeed the least traumatic for the psyche of the owners of this room, since it does not take much time and leaves virtually no traces.

The next plus: if the need arises, the plastic can be easily dismantled and checked, what state the space underneath is in.

Perhaps this advantage will seem to someone unnecessary thing, but, based on my experience, I can say that this is not so.

I'll tell you why I think so.

It sometimes happens that after installing a hermetically sealed window in a poorly ventilated room, dark spots appear on the walls, especially in the area of ​​the window opening and in the corners - this problem is called “the formation of moldy fungi.”

The fight against this phenomenon, long and difficult, begins with identifying the causes of mold, and they (the causes) can be of a wide variety of properties. We will consider them all in detail if you receive a question on this topic.

For now, I’ll focus on one of them, which directly relates to our conversation today. This reason is that the initial place for mold to appear can be the window opening, that is, the area around the window covered by slopes.

Mold formation is possible anywhere, but this requires compliance with several mandatory conditions: high humidity, lack of access to fresh air, variable temperature, lack of sunlight.

If the connection of the window block with the wall of the opening is made in violation of the rules that I have already told you about, then inevitably, whether under the plaster or under the plastic, mold will begin to appear.

True, mold in plaster travels a longer path before it comes out, but when it appears on the surface of the slope, it can only be completely destroyed by completely dismantling the plaster. Which, as you understand, is not an easy task at all.

When the reason for the appearance of mold is unclear, the only way to find out is to look at all the places where its victorious march through the apartment may have begun.

First of all, you probably want to look at what is being done under the plastic of the slope and make sure it is reliable window connection. That’s when the beauty of the quick-dismountable frame for PVX panels, which you will install in your apartment, will be revealed.

Another point in the list of advantages of plastic slopes is their cost b. Even if we add the cost of materials to the cost of work, then plastic slopes are beyond competition.

Moreover, the installation of PVC slopes will be unrivaled if you do them yourself, guided by my recommendations and spending only:

• your personal time;
• a small amount of money for building materials;
• some money for construction tool, which will probably come in handy more than once.

I think we can add here a point about the mandatory presence of a protective tape on the window profile, which many are in a hurry to remove immediately after installing the window unit.

You should be aware that this protection element can only be immediately dismantled from the outside s, since there is a possibility of it being welded to plastic under the influence of high temperature and sunlight.

The protective tape on the inside of the window frame can only be removed after finishing the slopes.

Otherwise, the surface of the window profile may be damaged, especially during plastering work.

When starting to finish the slopes, you need to worry about maintaining the window sill in pre-repair condition. In terms of protection, you cannot place much hope on the film that is applied to its surface, because a tool that accidentally falls out of your hands can leave an “indelible” mark on the surface of the window sill. Therefore, while the slopes are being built, it is best to place a piece of thick cardboard on the windowsill.

If finishing the slopes involves applying a plaster composition, then a prerequisite for the further normal operation of the curtains of the window sashes is their preservation from the ingress of sand from the solution. Some builders who did not pay attention to such a “trifle”, after a while, have to explain to the owners of the installed windows why the curtains suddenly began to creak and dangle.

Finally, I again want and must remind everyone who is going to replace the window units in their home and, of course, after this work, decorate the window slopes: the basis for the long-term service of any material used for finishing (even the most popular - plastic) is the high-quality arrangement of seats connection of the frame to the window opening.

About the angle of rotation of the slopes of plastic windows, see the video:

Reading time: 9 minutes.

When installing a plastic window, as a rule, the window opening loses its attractiveness. In this case, potholes, cracks, and remnants of polyurethane foam appear. What to do?

There is a simple way out - to make high-quality external slopes. To do this, it is enough to choose the right installation material and perform the work using existing technologies.

Let us dwell in more detail on issues related to the finishing of external slopes.

Purpose of external slopes

The coating inside the window opening, which protects the window profile from environmental influences, is called a slope. Conventionally, based on location, it is customary to distinguish external and. Although they are parts of the window opening, each has its own function.

The main functions of external slopes include:

• giving the glass unit an attractive appearance. A high-quality window structure should not be adjacent to a broken wall;

• increasing the level of thermal and sound insulation. Without high-quality slopes, it is impossible to create the necessary tightness of double-glazed windows, which means that the room will not be protected from the street;

• protection of the window frame from environmental influences. A well-equipped slope protects the mounting elements of the structure from corrosion; in addition, the possibility of freezing and fogging of the glass unit is reduced. In any case, a protected window frame lasts longer, which means it does not need to be repaired or replaced frequently.

When installing plastic windows, installers rarely finish the outer slopes at the same time. This work is significantly more expensive than installation and is performed separately.

The sun destroys the foam

Advice!

It is better not to put off finishing the external slopes for too long. Firstly, unprotected polyurethane foam has no strength, and secondly, it will have a bad effect on the condition of the window frame.

About materials

All materials for slopes create their own decorative look and different levels of glass protection.

When finishing, the advantages and disadvantages of materials must be taken into account. Typically, the following materials are used for finishing work on external slopes.

1. Plaster mixture.

As a long time ago known method plastering appears. The plaster mixture is prepared from different compositions. For exterior work, you cannot use a mixture with gypsum, as it absorbs moisture and then crumbles.

To the advantages plaster mixture applies:

• the ability to cover any surface;

• economic benefit;

• high resistance to moisture penetration.

Owners of plastic windows note the following disadvantages of plastered slopes:

• high labor intensity and duration of work. The solution is applied in layers;

• Low thermal insulation qualities of plaster can lead to freezing of slopes. In addition, condensation may accumulate and fungus may form.

1. Plastic.

Plastic panels have a hollow structure

The material is successfully used in window openings overlooking a loggia or balcony.

For slopes, sheet plastic or plastic panels are used.

The advantages of plastic slopes include:

• glossy surface harmonizes with the window profile;

• good thermal insulation qualities if you add insulation;

• a wide variety of color options;

• quick and easy installation with minimal waste;

• long service life.

How to make slopes on windows? This question worries many who, after replacing window designs I encountered this problem. Indeed, serious work remains to be done to make the surfaces reliable and beautiful. It is worth considering that slopes perform not only a decorative, but also a protective function. Therefore, it is necessary to approach this with utmost care. If you make mistakes or do the work poorly, a lot of troubles will arise.

Window slopes are an integral part of any room. Some believe that minimal attention can be paid to such a design. But this is a misconception that leads to the emergence of aesthetic and practical problems. The fact is that internal slopes perform a number of important functions:

1. Maintain a certain microclimate. Slopes prevent heat from escaping from the room to the outside, as well as preventing cold from penetrating inside. Naturally, protection from moisture, which leads to the formation of condensation, cannot be ruled out.
2. Extend the service life of all structures. That is why such finishing must be carried out in a short time. Of course, you can still delay installation indoors, but outside, installing the slopes is required within a minimum time.
3. They create an excellent decorative component. Installing slopes on windows can be considered one of the main components of a harmonious interior. You can install beautiful metal-plastic frames, but if they are not properly refined, they will lose their sophistication.

Therefore, when performing all the work yourself, you must comply with all technological nuances and rules. Then you can be sure that you will get a reliable and durable coating that will please the eye.

Design Features

The design of slopes has its own characteristics. The fact is that it is necessary to take into account the main nuances that must be done when working with your own hands:

• The structure should be finished so that the edge of the frame is covered quite a bit.
• It is necessary to take into account the location of hinges and opening doors.
• The foam is trimmed flush with the frame. If you remove more of the substance than required, the structure may become distorted. Also, any bulging residue will interfere with the finishing process.
• Particular attention is paid to the installation seam. The option that will be used for cladding the window slopes depends on its thickness.
• The sealing process is a very important point. All places must be well coated.

But how to finish the slopes, the location outside the room? The technology is almost completely consistent internal work. But the obligatory and most important rule will be to install a low tide.

Finish options

It is customary to distinguish two main cladding options, which differ in the materials used.

Cladding with panel products

This technology assumes that materials will be used that are cut into panels of the required size.

When choosing this method, the following features should be taken into account:

1. Quality of material. It is necessary to carefully select the products used. The fact is that if you install a low-quality option, then problems will begin to arise during the installation process. For example, cheap plastic is characterized by the fact that it crumbles and cracks when cut, and after installation it does not retain its good appearance for long.
2. Correct insulation and processing technology. When installing panel products, voids often arise, which can serve as an opportunity for the development of fungus and mold. Such places are a source of cold penetration. Therefore, surfaces require pre-treatment and installation of insulation, the choice of which depends on the specific situation.
3. Careful measurement. The main mistake that can happen is inaccuracies in measurements. If you do not take into account the location of the parts, wide joints will form that cannot be hidden even with decorative moldings.
4. Finishing. The installation of slopes from panel products must be combined with the correct selection of decorative elements. For subsequent finishing, you can use special profiles and corners, as well as putty external joints. When installing overhead fragments, it is important to make the correct trim so that all joints are equal.

On a note! To produce the most accurate parts for window slopes, two methods are used. The first is to simply measure and transfer data to the material, the second is to create stencils. This method is much more accurate, but requires more time, because it is necessary to perform a stencil at each stage of the work.

Application of the solution

Such work involves applying a certain layer of prepared mortar to the windows yourself, which completely covers the entire surface of the slopes. This option is considered the most traditional. His distinctive feature is cheapness.

Finishing can be carried out according to two main scenarios:

1. Traditional. The surface is finished with a mixture that is leveled at a certain angle.
2. With additional insulation. This technology involves the use of foam plastic, which serves as the base. In reality, this option can be fraught with many problems. Improper installation of insulation is a guarantee that numerous cracks and peelings will appear.

Preparatory activities

Before wondering how to properly make slopes, you should thoroughly prepare the surface. The amount of work depends on the specific situation. Exists general order, which is required:

Slope manufacturing technology

How to finish the slopes? There are basic materials that are used for such work:

• plastic PVC panels for walls;
• sandwich panels;
• plaster.

Each option is selected based on several reasons:

• Distance from wall to window frame. That is, the thickness of the assembly seam.
• Width of plots.
• Financial expenses.

Considering that the master must perform all the work himself, the option that will be most acceptable is chosen.

PVC panels for walls

PVC panels are the most popular material for finishing window slopes

This material is used most often, especially if needed. There are several reasons for this:

1. Cheapness. Modern technologies allow us to produce products that are accessible to everyone.
2. Practicality. If you choose materials that do not belong to the category of economy, then they are unpretentious in operation and last quite a long time.
3. Easy to install. The work is completed quickly, without the use of complex tools.

Installation of slopes made of plastic panels is carried out according to the following instructions:

But the window decoration is not finished yet. A number of finishing manipulations should be performed. They consist in the fact that all joints are well coated with sealant. Decorative corners are installed on the outside. They must be trimmed correctly in order to join at an angle of 90 degrees.

When a dilemma arises about which slopes are better, many proposals and opinions may arise. But it is undeniable that it is better to make slopes from sandwich panels. They combine all the positive qualities PVC materials, but have additional advantages:

• The products include a reliable layer of protection (one or two), as well as a layer of insulation. This avoids the need to use additional material.
• They are resistant to various influences, due to which their service life is practically unlimited.
• They have an excellent decorative appearance. Indeed, such panels are superior in appearance to wall products. In addition, this material can be made in a fairly wide size, which is ideal for large openings.

Making slopes on windows with your own hands using such products is quite simple. It must be taken into account that this option is excellent in cases where the thickness of the installation seam is minimal. Three-layer material is used for work.

Let's look at how to install slopes from sandwich panels. Everything is done as follows:

Using plaster

Previously, there were no questions about how to make slopes on windows. After all, there was only one option, which was to use plaster. This method quite convenient and practical, but requires skills. This need arises due to the fact that it is necessary to correctly display all the planes and maintain the angle of inclination. Although, if you practice a little and understand how best to apply the mixture, then plastering work will not cause any particular difficulties.

The general technology is as follows:

The result is an excellent coating that is highly reliable. The undoubted advantage of this option is that each section made can be repaired and the decorative layer can be changed.

Conclusion

Summarizing the above, we can conclude that there are various options for finishing window slopes, which depend on the specific situation and financial capabilities. The main thing is to initially carry out all the work efficiently, observing all the nuances.

After installing new plastic windows, the question arises of how to install PVC window slopes without the involvement of specialists. Our article today will help you choose the material and carry out the work.

What role do window slopes play?

The installation of PVC windows has been completed, but you notice that something is missing, and the window itself looks sloppy and even rough? The reason is the lack of slopes, which must be installed. The main problem when installing new windows is that it will not be possible to carry out the installation without removing the old slopes and part of the wall, no matter what professionals carry out the work. So it turns out that after installation the window block looks like it was after a bombing. To create complete harmony and merge the windows with the interior of the apartment, you will have to restore the slopes.

Today there are various ways for finishing the window opening: the use of plaster and paint (traditional) and the use of plastic slopes (modern).

Undoubtedly, the first option will allow you to enjoy a beautiful appearance for a long time, but only if you carry out restoration work every couple of years. At the same time, the complexity of the work is at a high level. But the installation of PVC slopes can be carried out even by a construction novice. And it will take an order of magnitude less time to complete this work. If you decide that you can live without slopes, this will not only spoil the appearance, but may cause strong drafts to appear in the house, which will lead to heat loss.

Why should you choose plastic slopes for PVC windows?

To answer this question, it is worth studying everything possible materials, which can be used to create slopes. This will allow you to evaluate all their advantages and disadvantages and compare them with each other.

Types of slopes:

• Plastering. If we talk about plaster slopes, then they have more disadvantages than advantages. First of all, the plaster soon begins to crack, loses its brightness due to direct exposure to sunlight, and when the building subsides, it may even move away from the walls. In addition, the disadvantages of slopes include the inconvenience associated with the time of work. Slopes are plastered in at least two or three layers, each of which must dry, which takes time. After this, the surface is primed and painted. The work may take up to several weeks. Also, such slopes do not provide for the creation of suitable thermal insulation, which will lead to condensation.
  
• Slopes made of gypsum board. Such products are more durable than plastered slopes, and if they are insulated with mineral wool, they provide very high thermal insulation properties. But there are also disadvantages: gypsum board sheets are afraid of moisture, and therefore a high level of waterproofing is not for them. That is why such slopes are only suitable for installation in rooms with low humidity levels.
• A modern solution is PVC slopes, which are quite easy to install yourself. This material has many advantages. First of all, it is quick installation, simple and easy to maintain, plastic does not fade in the sun. In addition, such slopes will serve you for at least 15 years. If you carefully select the slopes to match the shade of the window frame, the harmony between the products will be perfect. Using mineral wool, you will provide excellent heat and sound insulation.
  

True, there are some disadvantages. For example, such slopes have a low level of resistance to mechanical damage, and therefore they should be treated carefully, using a regular damp cloth for cleaning. Also be careful when installing PVC panels for window slopes. As the famous saying goes, it is better to measure seven times and only then cut. If some mistake does occur, use regular silicone putty to seal the PVC.

Do-it-yourself PVC slope installation

Installation of plastic slopes according to all the rules will allow window openings look 100%, the windows will not be afraid of humidity, you will forget about possible cracks on the surface. But this is only possible if the installation work is carried out in compliance with all norms and regulations. This is what we will talk about.

How to install PVC slopes with your own hands - step-by-step diagram

Step 1: Prepare the surface

You can begin installation literally a day after the installation of the window unit. Approaching the window, you will find a large number of polyurethane foam, which appears at the joints between the profiles and the wall. It must be trimmed, for which use a sharp stationery knife. After this, the surface of the slopes is cleaned of dust and dirt.

Step 2: Installation of the guide profile

First, find out the dimensions of the profiles along the outer edge using a measuring tape. Also be sure to measure the outside width of the profile and the distance from the top of the window to the sill. By the way, before carrying out work it is best to either remove part of the frame or bend the film a little.

As a guide, it is customary to use a U-shaped profile of the required width, which is cut into the necessary elements. For this job it is better to use . After this, the profile is attached to the outer part of the window frame with screws, and the fasteners should go every 20 cm. We fasten the top and side profiles in the same way.

Step 3: Installation of sheathing elements

To create the sheathing, you need to use wooden slats with a cross-section of 2*4 cm. They are attached to the far corner of the slope on top and on the sides. To fix the slats, use dowels; the distance between the nails should be around 30 cm. It is important that the sheathing is perfectly flat, for which you can use a plane - using this tool, carefully trim the thickness of the slats. At the end of the work, check the levelness with a building level.
