How to insulate a balcony with your own hands: from a refrigerator to a warm island. Internal insulation of loggia walls: which material is more reliable How to insulate and finish the interior of a loggia

Loggia is several square meters, which can serve a variety of purposes. To use this premises all year round, you need to ensure a comfortable temperature there. Anyone can transform it into a cozy, useful and well-equipped space. home handyman.

Are you planning to start arranging these additional square meters, but don’t know how to insulate the loggia with your own hands and what materials will be needed for this? We will help you deal with all the issues - our article provides recommendations for choosing insulation and discusses step-by-step instruction for thermal insulation of the walls, ceiling and floor of the loggia.

You should start, of course, with planning. You should decide on functional purpose this small room. If you plan to use it as a warehouse for things that are not very necessary, then insulation does not make much sense. But the loggia can be turned into an office, a small gym, winter Garden and so on.

There are also restrictions. For example, a loggia cannot be used as a kitchen space, i.e. install a stove, a sink for washing dishes, etc. Carry out the system to this area central heating also prohibited.

There are a number of other restrictions that may be associated with architectural features And fire safety building. This may be a ban on glazing above a certain floor, on changing the appearance of the building, the height of the fence, etc.

As practice shows, many manage to somehow circumvent these standards and arrange a loggia to their liking. Before starting work, it doesn’t hurt to coordinate your plans with supervisory authorities or prepare for problems to arise after the rework is completed.

Installation of electrical wiring, lighting and heated floors during insulation of the loggia must be thought out in advance so that damage to the heat-insulating material is minimal

But under no circumstances should openings be made in load-bearing wall, only the holes provided for in the original design are allowed. Even taken from the loggia window-door block may pose a danger.

To keep the loggia warm, you will need high-quality glazing. It is better to order it from a reliable company. Double-glazed windows will do the job perfectly.

Part of the space will be “eaten up” by a layer of insulation. These centimeters will have to be sacrificed in order to reliably protect the house from the cold. Loggias located on the lower floors are most often insulated from the outside. ABOUT the best materials for external wall insulation we.

From the very beginning, you need to consider options for heating this space.

There are not so many of them, because only suitable for a loggia:

electric TP;
portable heater.

Considering that the installation area is small, you can spend money on such convenience as a TP. Cable systems are easy to install; you can do all the work yourself. Infrared flooring is more difficult to install; it requires almost perfect level base, but electricity costs during operation will be moderate.

But most simple solution there will be use, especially if the loggia is not used every day, but only from time to time. Installing heated floors will require more expense and effort.

The choice of materials and options for insulating a loggia with your own hands is quite wide.

Among the most popular it is worth noting:

mineral wool;
Styrofoam;
polyurethane foam;
expanded polystyrene;
penofol, etc.

Mineral wool has a low price, but this is almost its only advantage. To lay such material, you will need to first arrange the lathing. Mineral wool is sensitive to moisture; when wet, it loses its beneficial features, so it is not always suitable for a loggia.

You need to provide a place for installation in advance. Usually a niche of a suitable size is made on the wall for these purposes. A temperature sensor placed in a corrugated tube is placed among the turns of the cable TP. It will also need to be connected to the thermostat.

How to properly insulate a balcony from the inside with your own hands - this is the question I had to ask myself when the idea came to my mind to turn our ownerless balcony into a home one. As it turns out, I am not at all comfortable sewing in a room that is a child’s room. I wanted solitude and silence so that I could be completely focused on work, and I also interfered with the children’s study and recreation.

In this article I will talk about how we carried out renovations to transform our cold and drafty loggia into living room, or rather to my office and how much it cost us. I will also give valuable advice that will help you avoid mistakes and save your nerves and money)

How to insulate a balcony from the inside with your own hands

What I had to face and what our loggia looked like before insulation

When I told my friends about my idea, at first everyone laughed at me. They began to say that there was not enough space there, and they were frightened by the cold of the unheated room - after all, our loggia was essentially an outdoor room. To give you an idea of what I had to face, I am attaching a plan of the balcony. I had to turn three and a half squares of usable space into a full-fledged office, where my two Sewing machines with a table cutting table, ironing board.

The first window has a balcony door and access to the kitchen. This wall is the main one - it’s already warm, so you don’t have to sheathe it. Subsequently, we abandoned covering it with plaster, since the brick itself looks quite interesting in the interior. We just cleaned its surface from dirt with sandpaper.

The second window is located on the wall of the loggia, it required complete replacement and hit the stained glass windows. The photo was taken after installing a new double-glazed window.

Replacing a window on a balcony

The first thing my story with the balcony began was the replacement of the existing double-glazed window. When we moved into our new building, we saw that on the loggia (unlike other rooms) the developer installed windows in one layer of glass. Of course it was summer option, they missed the cold with all their might. There was no talk about replacing the double-glazed windows, because I also wanted to change the shape of the frame and make the opening sash of different sizes. I don’t know how the design of our house was made, but the architect clearly did not make an effort for the convenience of the residents. Therefore, first of all, I found a company that manufactured a high-quality two-chamber window according to our dimensions. As the window manufacturers stated, such a window provides 25% more heat retention in the room than the one supplied by the developer.

When ordering a new window, there was one small point that significantly increased the amount of our costs - lamination. That is, from the street side, all the window frames of our house are dark - burgundy color, under the tree. Therefore, we also had to not get out of big picture and make a window in general color scheme. For lamination, window manufacturing companies charge 20% of the total cost.

The price for a window measuring 2580 * 1520 cm with a burgundy frame, including installation and delivery, was 20,700 rubles. And we sold the dismantled old window at a profit on the Avito website.

Important (!)- if you are going to subsequently insulate the balcony and increase the ceiling after installing the window, then tell the window technicians about it. They will put expanders on top part windows so that later your extended ceiling does not cover the shutters and you can hang curtains.

Heating a loggia, which method to choose

A loggia usually has walls made of one layer of brick; the worst option is a balcony made of corrugated sheets. Therefore, to feel comfortable in this room during the cold season, a heater is needed.

There are two options for making your loggia warm. The first one is to open balcony door so that it is heated by the adjacent room. The second is to install electric “warm” floors or buy oil radiators.

I’ll tell you right away from our experience - one heater was not enough for us, and we decided to install a warm floor. Despite the fact that the walls of our loggia were insulated, there was cold from the neighbors above and below - after all, their balconies remained uninsulated.

Selecting material for insulating a loggia (balcony)

At the very beginning, my husband was advised to do the insulation of the balcony with his own hands; in general, he is handy - he can lay laminate flooring and tiles. But in the case of the balcony, I didn’t have time to wait for him to find free time; here I needed the work of a professional, since correcting mistakes would cost more. So we found a master who is engaged in this business and observed his work from the side. I found it through Avito, which is what I paid attention to first of all - real photos and living in our area (so that he has the opportunity to go to lunch without spending a lot of time).

I didn’t just want to cover the balcony with panels, but to make walls that could later be covered with wallpaper, so for internal lining we chose drywall. Finding a good specialist who would work with drywall and install wiring (after all, I also needed sockets and lighting) turned out to be not an easy task. But I was lucky and found good specialist, who promised me to bring my idea to life! On his advice, after taking all measurements, we purchased the following to insulate our loggia:

plasterboard - for walls and ceilings
plywood - for the floor
TechnoNIKOL Rocklight - for floors
technoNIKOL technoplex - for walls and ceilings
isolar - reflective metallized substrate
bars

The most important thing on this list is insulation. It is thanks to this that you get a full-fledged living room. We chose two types of insulation:

The first type, for floor insulation, is TechnoNIKOL Rocklight. It consists of rectangular slabs pressed from basalt fibers; popularly it is called mineral wool. There is no need to be afraid that it can have an adverse effect on the air in the room (many write about harmful fumes, etc.), on the contrary, due to its ability to pass moisture rather than retain it, it is widely used for insulating damp rooms where there is a possibility of mold and mildew . According to the Technonikol company, its slabs do not burn and do not absorb moisture, therefore today they are recognized as the most the best insulation materials On the market. In order to cover the floors of a 3.8 m2 loggia in two layers, we needed 1 package of TechnoNIKOL Rocklight, which contained 12 slabs.

The second insulation we used is TechnoNIKOL Technoplex for internal wall cladding. As I mentioned above, the developer built our loggia in one layer of brick, due to this there was a blast from every corner. In addition, inconvenient stained glass windows were installed in the loggia on either side of the window, which from the outside gave the house a business-like appearance, but inside served as a source of constant drafts and moisture for the residents. This type the insulation is made of nanographite, due to this it has an unsightly grey colour. Although by weight appearance it reminded me more of polystyrene foam, but despite its lightness it has excellent thermal insulation characteristics. After our balcony stopped looking like a bamboo hut, I started thinking about how to use these magic slabs to soundproof the living room from neighbors)

The third type of insulation- it rather comes as an addition to the first two, it is metallized substrate isolon or isolar. We all know that a shiny surface is highly reflective. It is this ability of the metallized surface of the substrate that allows you to redirect heat inside the room, as if reflecting it and preventing it from escaping outside.

As a result, I can say that all the insulation materials coped with their tasks with a bang, they really retain heat, like a thermos. But at the same time they miss excess moisture, preventing the formation of mold.

How to insulate a balcony with your own hands step by step photo

1. Cleared the balcony of everything unnecessary. Before the technician arrived, we cleaned our balcony of rubbish and debris, a window was already installed and heating radiators were installed.

2. Patching “holes” in stained glass windows using TechnoNIKOL Technoplex insulation boards. This did not affect the appearance of the house in any way, and for us the problem of eternal drafts was solved. The slabs were laid in two layers, all the cracks were filled polyurethane foam.

After taking measurements, cutting the slabs is done using a jigsaw and a hacksaw for metal.

3. Exiting electrical wiring to the balcony. In my workshop it was planned to install three sockets for sewing machines and a laptop; the wires were pulled from the nearest socket in the kitchen.

4. Insulation of the floor using beams and TechnoNIKOL Rocklight insulation (mineral wool). According to our master, he likes to work with this type of insulation most of all. Since when placed between the beams, it expands on its own and does not leave any gaps, which means it does not require the use of polyurethane foam.

Although basalt wool and glass wool are two different things, I still played it safe and carefully closed the door to the balcony while he was laying the floors. And then I vacuumed all the walls for an hour. Our master, of course, laughed for a long time when he saw me walking around in a medical mask and gloves. For me, any mention of glass wool is a fear from childhood, when we ran around a construction site and accidentally touched glass wool, any of us received a burn, after which it itched and burned for a long time.

First, a frame or so-called formwork for the future floor and walls is assembled from wooden blocks. The slats are fastened together with metal corners using dowels and a screwdriver.

If the frame is laid on concrete, then first use impact drill holes are drilled on concrete floor at fastening points. Then in wooden joists Dowels are inserted, applied to the fastening points and the screws are driven in with a hammer.

Mats from mineral wool can be placed directly on concrete screed, in a wooden frame between the joists. It does not shrink at all, so it is used even on high-traffic surfaces.

To give the floor additional thermal insulation properties— on top of the first layer of basalt wool insulation, you can build a second sheathing frame and lay another layer of TechnoNIKOL Rocklight in the same way. In this case wooden blocks are attached with a screwdriver to self-tapping screws.

Next, an isolar layer is used - this is a metallized substrate that reflects heat and protects from moisture; it is widely used to create a warm balcony (loggia). After laying all the layers of building materials, we reached the same floor level as the room without thresholds or steps.

Important (!)— the metallized substrate is laid with the reflective surface facing up.

5. Insulation of the ceiling using TechnoNIKOL Technoplex insulation. Two wires were installed in our ceiling ceiling lamps. Therefore, before proceeding with the installation of the ceiling, electrical wiring was installed under the wooden beams. I really like this method - it looks neat, without unnecessary wires. Electricians have a lot to learn from Bashkir masters)

6. Insulation of walls using TechnoNIKOL Technoplex insulation.

The main difference between nanographite insulation and basalt wool is that it is not elastic. Therefore, when installing it in the sheathing, gaps remain, which then need to be filled with polyurethane foam.

After all the joints have been processed, a metallized Isolar substrate is applied on top of the insulation. It is attached to the sheathing using a stapler and special adhesive tape (connecting tape) - isospan.

After covering the entire surface with a metallized substrate, on top using self-tapping screws and a screwdriver to wooden sheathing sheets of plasterboard are attached.

Plastering a balcony (loggia) with your own hands

After the balcony was completely covered with plasterboard sheets, including the ceiling, we had to plaster the walls. Wallpaper cannot be glued to bare drywall because upper layer It is made of paper and can come off if wet. Additional surface treatment of sheets includes primer and putty.

At this stage of the work, our master left us, since he was only involved in insulation, and the work of a plasterer and painter was not part of his duties. We had a choice - either find a new worker, or pick up a spatula ourselves. A significant role in the choice was played by the amount that the plasterers - professionals - asked for the treatment of our small area.

Therefore, my friends, for the first time in my life I picked up a spatula and plastered my balcony myself (I posted a photo with the result below). But I will say right away that I liked plastering, as it turned out, working with the gypsum mixture is not at all difficult, and if you are not particularly picky about your walls, feel free to pick up a trowel and master the new kind activities! Subsequently (as experienced craftsmen scared me) after drying, nothing fell off, and the loggia became even warmer - after all, I myself responsibly covered all the cracks and joints.

So, to plaster a balcony covered with sheets of plasterboard I needed:

gypsum plaster “Volma layer”
deep penetration primer for drywall
Serpyanka tape for joints
putty knife
container for diluting plaster
drill with mixer attachment for mixing the solution
oilcloth to protect the surface from dirt (floor and brick wall)

1. First I went over the walls with a primer to improve the adhesion of the finish coat. Waited 40 minutes until completely dry.

2. I sealed all the joints on the drywall with sickle tape. It forms a strong adhesion to the binder mixture, which is especially important at seams and corners.

3. Prepare the solution. I first diluted everything according to the instructions, and then mixed the plaster with water by eye. The second time you already know exactly what consistency the solution should be. I applied the plaster in two layers. It took me four hours to work. I concluded that you can cope and learn how to work with a spatula even if you are a beginner. You can judge what I got from the photo. After drying, the color of the Volma layer plaster becomes gray rather than white, so the ceiling had to be whitewashed with water-based paint.

How much money did it cost us to insulate the balcony with our own hands?

Double-chamber window with lamination (installation, installation) - 20.700
Nails, switches, sockets, cable, foam, sealant - 4,800
Insulation, bars, drywall, plywood - 11,600
Window sills, window frames, laminate, wallpaper, lamps - 4,000
Master's work - 10,000

Total for our loggia with an area of 3.43 sq.m. It took us 51,100 rubles. The amount of costs depends on the size of the area to be insulated and what materials will be used for this. As you understand, insulating a balcony in a Khrushchev-era building will cost much less than insulating large balcony with panoramic windows.

1. Be mentally prepared for the fact that you will need to allocate temporary space for building materials. All these insulation, sheets of plasterboard and wooden blocks are impressive in size and took up our entire hallway with an area of 13 sq.m. It was especially difficult for me with small children, whom you couldn’t keep in place and you had to constantly make sure that they didn’t trip and spread dirt around the apartment.

2. Separately, it is worth mentioning garbage and dust. Despite the fact that all the dirty work was carried out on the loggia, the builder still had to walk between the balcony and the hallway for materials and tools. Therefore, the entire floor was strewn with shavings and debris. Every time after his work I had to spend time in the house wet cleaning with a rag and a vacuum cleaner. This important reason- why I wanted to quickly finish insulating the loggia.

3. The amount that was initially agreed upon for the purchase of building materials was approximate. That is, in the process you still had to buy something in addition.

4. One person definitely cannot handle all the work. There are two options: find a company that does turnkey repairs, the prices of which start from 50 thousand rubles. Or, as we did, we separately looked for a wizard for each option. As a result, for the entire process of insulating our loggia, we needed: specialists in the manufacture and installation of windows, a plumber, a specialist in insulation and cladding of balconies, a plasterer and a painter. It turned out cheaper than ordering from an organization, but I also had to spend time searching.

5. Keep in mind that if you decide to insulate the balcony yourself without the help of a specialist, then you should have the necessary tools for the job at hand. These are a jigsaw and files, a drill, a hammer, a screwdriver, a sealant gun, a hammer drill, a construction ruler with a level, an assembly construction knife for drywall, construction stapler.

6. Don’t throw away receipts; they may come in handy when repairs are completed and there are unused building materials left. Within 14 days from the date of purchase, you can return them to the store and get your money back, provided that the packaging remains unopened.

7. It is better to make purchases in large chain stores. For example, Leroy Merlin gives customers the opportunity to return unused items for repair within 100 days after the purchase. I didn’t have any difficulty returning extra rolls of wallpaper, glue and curtain rods that didn’t match the height.

Conclusion

I hope our experience helped you on how to properly insulate a balcony from the inside with your own hands with step-by-step photos. Many people complain that after insulation the loggia still remains cold. We specifically measured the temperature on the balcony, when it was below zero outside. She remained as warm and comfortable as in the apartment.

The work of insulating a balcony is of course difficult and dirty. But how much joy I now have in my own workshop. I have my own little corner where I can work quietly without disturbing my loved ones, and create in my personal space. So if you have an idea to make yourself a study, but there is no space in your apartment, pay attention to the balcony or loggia. Good luck everyone, bye!

By insulating the balcony, you can achieve two goals at once: expand the living space and improve the degree of thermal insulation of the apartment. It is best to carry out external insulation, but this cannot be done without the services of industrial climbers and the corresponding costs. Insulating a balcony from the inside will cost much less, especially if you do it yourself.

How to insulate a balcony inside

The positive result of the work performed is considered equally comfortable temperature inside the room and the adjacent balcony. There is no point in investing effort and money in insulation that does not protect against the penetration of cold onto the balcony and forces you to tightly close the doors leading to the loggia in winter.

As a rule, for internal insulation of balconies the following is used:

foamed polystyrene with a density of 25-35 kg/m 3, otherwise - polystyrene foam;
based on basalt fiber 80-110 kg/m 3 density;
extruded polystyrene foam (one of its varieties is).

Note! For additional thermal insulation, thin foil polyethylene foam insulation - Izolon or Penofol - is often laid on the base layer.

In addition to the listed insulators, there is another insulating material - ecowool, made from cellulose waste. Simply put, waste paper. The rules for handling it and the installation technology used are the same as with basalt wool. Ecowool is not very popular due to its high cost.

Brief characteristics of insulation

Foam plastic is the most cheap material for insulation, produced in the form of slabs of various thicknesses.

Like all foamed polymers, it repels moisture well and has sufficient strength (at the specified density). It is characterized by high resistance to heat transfer and flammability, which is why it requires protection from an accidental spark.

The thickness of the foam for insulating a balcony in the northern regions should be at least 100 mm; in the southern regions, 50 mm may be enough.

Unlike polystyrene foam, mineral wool does not burn at all, but it is capable of absorbing moisture, after which its thermal conductivity increases sharply. The problem is solved with the help of protective layers of special films, which will be discussed below.

The heat transfer resistance of mineral wool is not very high, so it makes no sense to use material less than 80 mm thick. The insulation is offered in rolls and slabs, and is more expensive than polystyrene.

Advice! You should not insulate your balcony with fiberglass wool (glass wool) intended for outdoor or roofing works. The use of such materials inside residential premises is unacceptable.

The best option for internal insulation of a balcony is extruded polystyrene foam, sold in slabs.

Expanded polystyrene is durable, lightweight and has the best thermal insulation properties.

Where you need to lay mineral wool 100 mm thick, 50 mm of penoplex is enough.

In addition, the polymer does not allow moisture to pass through at all and is so strong that the slab can be screwed on with self-tapping screws if necessary. There is only one drawback - the high price of the material, which is compensated by the long service life of the material - up to 50 years.

Technology for insulating a balcony from the inside

It is necessary to carefully prepare for thermal insulation on the balcony. This includes not only the acquisition of materials and preparation of tools, but also the performance of a number of preliminary works:

Construction of a reliable parapet. There are 2 types of structures in practice: a welded metal frame with fastening to the wall or masonry made of foam blocks. How to strengthen a parapet - .
. Sometimes the balcony is made panoramic by installing metal-plastic blocks to the full height, without a parapet. Then all that remains is to insulate the floors and ceiling.
Elimination of all cracks and leaks leading to the street, removal of excess polyurethane foam.
Pad electrical wiring for lighting, as well as drainage and lines with freon to (if available).

Before insulating the inside of the balcony, you need to level all surfaces, removing obvious sagging or filling in depressions and cracks with mortar.

Interior wall decoration

The technology for insulating balcony walls, done with your own hands, depends on the design of the parapet and the type of thermal insulation material. Metal carcass, trimmed on the outside with plastic or, it is better to sheathe it with 2 layers of thermal insulation so that the second row of insulation covers everything metal racks, which are cold bridges. And with outside, between the cladding and the insulation, a windproof film should be laid.

When insulating a balcony with mineral wool, it is necessary to use not an ordinary film, but a diffusion membrane as a wind barrier. It will let out the moisture that arises in the thickness of the cotton wool, but will not allow it to get wet from precipitation or fog on the street. For polystyrene foam and expanded polystyrene, the use of a membrane is not necessary; ordinary film will do.

To attach the mineral wool, you will need to assemble with your own hands an additional wooden frame from beams, the width of which is equal to the thickness of the insulation. The pitch between the bars is selected according to the width of the material, the latter is placed between them at random. At the last stage, the thermal insulation layer is covered vapor barrier film, after which the frame is covered with clapboard or plasterboard.

Headlining

And the balcony ceiling can be insulated in 3 ways:

If you plan to do wallpapering at the end, then the method of gluing slab insulation is suitable mortar. Insulation accompanied by “wet” processes is carried out only in warm period years at above-zero temperatures.
For or similar finishing you will have to attach wooden blocks to the walls and ceiling, and a rolled or slab material lay between them.
When insulated with polystyrene foam, the slabs can be directly attached to the walls and ceiling with dowels. After which the surfaces are leveled with putty and painted, or lathing is installed by attaching the bars to foam blocks or concrete through the insulation. Cladding, plastic, plasterboard and other finishes of your choice are easily attached to the sheathing.

Note! For fastening the sheathing to concrete ceiling through polystyrene foam you need to use special concrete screws - frame dowels.

When insulating a balcony with mineral wool without wooden frame not enough. You can glue cotton wool, but it is quite difficult. The best option– insert it between the beams attached to the wall and ceiling, protect it with a vapor barrier and cover it with a suitable material.

The gluing method is convenient when working with polystyrene foam, but after 2 days it must be additionally secured with dowel umbrellas and applied plaster layer on fiberglass mesh.

Floor insulation

The technology for thermal insulation of balcony floors differs from walls and ceilings, since the insulation “pie” must bear certain dynamic loads and have a flat surface. Leveling is carried out by laying wooden logs, between which insulation is laid, and a finishing coating is laid on top. The sequence of actions is as follows:

Cut the wooden beams into cross members along the width of the balcony and secure them to the floor with anchors or self-tapping screws and dowels using steel corners.
Attach 3 longitudinal logs to the crossbars with self-tapping screws. During the process, they must be aligned horizontally, starting from the highest point. Using a building level, the beams at the intersections with the crossbars should be raised and plastic or wooden wedges placed.
Place insulation tightly between the crossbars and the joists. In the case of mineral wool, a vapor barrier must be laid on top of it.
Lay the flooring with fastening to the joists.

It is typical that the length of the crossbars and joists do not need to be adjusted to the dimensions of the balcony. It would be more correct to make them 10-20 mm shorter so that the ends do not rest against the walls. Wood has the ability to “breathe” and deform slightly; if the fit is tight, the floor surface may later bend in an arc.

Moreover, walking on such floors will be accompanied by an annoying squeak. The resulting gaps near the walls will hide under floor covering and will become invisible.

When using slab insulation, it is worth choosing the correct spacing of the crossbars so that you do not have to cut the slabs again. The standard width is 600 mm, and this is what you need to focus on. After laying polystyrene foam or expanded polystyrene, all joints and cracks must be filled with polyurethane foam.

Useful training video:

The mineral wool is protected with a vapor barrier as tightly as possible so that moisture from inside the room cannot seep into it. Here you can also use foamed polyethylenes such as Penofol, but pay attention Special attention gluing joints.

If you take a serious and scrupulous approach to the procedure for internal insulation of a balcony, then it is not at all necessary to hire craftsmen and pay them money, which is never superfluous. You will spend twice as much time on completing the work, but you will do everything efficiently and in accordance with your personal wishes. In addition, you will save money on your family budget.

Do you have to forget about the balcony in winter? It's time for a change - turn your warehouse of unnecessary things into a warm, cozy corner or even! Insulate cold balcony both in a new building and in a private house it is not as difficult as it seems: it is enough to know what materials can be used and in what sequence the insulation work should be carried out.

To begin with, it’s worth saying that there are two ways to insulate a balcony – from the inside and the outside. External insulation, of course, is more convenient - precious centimeters of space are not “eaten up”, and the cladding of the balcony facade becomes more pleasant. But this is a labor-intensive process that requires the involvement of a construction team and industrial climbers. Therefore, in this article we will focus on how to properly insulate a balcony in an apartment from the inside - you can do this yourself.

To insulate the inside of the balcony, you first need to carry out preparatory work. They include several important steps:

Where to start insulating a loggia or balcony? Free up space from everything unnecessary. It’s best if the balcony is completely empty: it’s much easier to work this way. Also, get rid of old trim in advance.
Seal all the cracks - a lot of heat escapes through them. For small gaps, a weather-resistant sealant is suitable; fill larger ones with mounting foam - it will not only fill the voids, but will also serve as an additional heat insulator.
To make it easier for you to carry out insulation work, it is important to smooth out cracks and irregularities in the walls and ceiling using cement mortar.
If you plan to place light bulbs or lighting, it is worth taking care of the wiring in advance. To hide unsightly cables, place them in plastic boxes.
Before starting work, cover the opening between the balcony and the adjacent room with film so that construction dust and other pollutants did not enter the apartment.

Is it possible to insulate a balcony in winter? Yes, you can. Only when carrying out work in winter is it necessary to choose frost-resistant materials, in particular polyurethane foam.

How to insulate a balcony: what materials are best to choose

To understand how to insulate a loggia or balcony, let’s first figure out what properties the materials should have:

high strength;
fire safety;
water resistance;
environmental friendliness;
relatively low cost;
ease of installation (if we want to do all the work ourselves).

Most often, mineral wool, polystyrene foam, polystyrene foam, etc. are used for insulation. Sometimes several of these materials are combined. We have reflected the pros and cons of each heat insulator in the table:

Insulation	Advantages	Flaws
Expanded clay>	Low cost; Durability; Fire safety; Not afraid of mold and mildew; Light weight; Easily takes any shape	High moisture permeability; Suitable only for floor insulation; May be difficult to install





Mineral wool	Good sound and heat insulation; Environmental friendliness; Fire safety; Easily takes any shape	Deterioration of properties when exposed to water; The thickness of the insulation “steals” the usable area



Styrofoam	Low cost; Easy installation; Light weight; Not afraid of mold and mildew	Fragility; Flammability




Extruded polystyrene foam in slabs	High strength; Easy installation; Moisture resistance; Durability	Relatively high cost



Polyurethane foam(liquid insulation)	High strength; Moisture resistance; Durability; Fills cavities of any shape	Relatively high cost; Mandatory availability of special equipment



Penofol(foamed polyethylene with a layer of metal foil)	Moisture resistance; Durability; Small thickness; Good thermal and waterproofing	Rarely used as an independent heat insulator, usually only in combination with other materials

Which insulation for a balcony is better? The answer to this question depends on your preferences and financial capabilities. You can read more about the characteristics of insulation, as well as in general, in our blog.

First, it is necessary to lay a waterproofing layer of polyethylene or penofol on the floor so that dampness does not bother us. Craftsmen advise laying penofol with the reflective side up. At the same time, we can attach the waterproofing material to the walls. It is better to glue the joints between the sheets of waterproofing with foil tape.

Another good waterproofing agent is bitumen-based mastic. It dries for about a day; surfaces treated with it should not be touched.

Then we install logs - wooden beams or metal beams that serve as the basis for floors, platforms and other surfaces. Wooden logs are suitable for floor insulation. You should choose logs made from quality materials: The moisture content of wood should not exceed 12%. Also, in order to prevent fungus and rotting, the beams are treated with an antiseptic or primer.

The distance between the logs should be equal to the width of the insulation, and builders recommend making the height of the beams 10-15 centimeters - this is necessary for reliable protection floors from frost. To seal the holes between the joists and the wall, and also to secure the beams in the desired position, use polyurethane foam. Don't worry about being careful: excess foam can be cut off with a knife after it dries.

Next, a thermal insulation layer, slab or fiber, is laid. Make sure that there are no gaps between the heat insulator and the joists: “cold bridges” will negate all your insulation efforts. If you are laying insulation in several layers, be sure to move each new layer so that the seams between the insulation sheets are not in the same place.

To protect the floor from condensation, you will need a layer of vapor barrier.

Using self-tapping screws, attach a “sub-floor” made of boards, sheets of plywood, fiberboard or chipboard to the joists. This last step before finishing floors such as laminate, linoleum or carpet.

There are two technologies for insulating the ceiling - with or without a frame. Before starting work, it is recommended to apply an antiseptic layer to the ceiling: this will protect the surface from mold.

If you decide to make a sheathing, you will need wooden blocks and dowels. We put insulation into the sheathing - mineral wool or polystyrene foam is suitable as a thermal insulation layer. Mineral wool is secured with polyurethane foam, and the foam holds without additional fastening. Then the ceiling is finished: plastic panels, drywall, lining - any materials will do, it all depends on your idea.

Without a frame, ceiling insulation work is carried out as follows: the ceiling surface must be cleaned of dust and dirt, and also treated with strengthening primer - this will help fix the insulation more reliably. Then the glue is applied to the foam sheets (it is enough to apply glue along the perimeter and a little in the middle). We glue the sheets to the ceiling; for reliability, they are attached using dowel mushrooms. We seal the joints with polyurethane foam.

The glue you will use should under no circumstances contain toluene.

We already have the waterproofing ready, so we can immediately install the sheathing made of wooden blocks. The distance between them should be equal to the width of the heat insulation, and the height of the bars should be equal to the width of the insulation. Suitable for walls polystyrene foam boards, polystyrene foam or high-quality mineral wool. As always, we fill the joints between the insulation with foam. A vapor barrier film must be secured over the insulation.

As a rule, the wall between the balcony and the room is insulated in one layer, and the remaining walls in two layers, or the thickest heat insulator is used.

What to do with the windows?

Think about it: is it worth insulating a balcony with cold glazing? If you want a truly warm corner, you shouldn’t skimp on windows. You can insulate the ceiling, floor and walls to the highest standard, but cold air will still leak through old or low-quality double-glazed windows.

If your balcony is not glazed, first of all pay attention to the parapet - a low wall that protects the balcony from the street. It must be strong enough to support the window structure.

Which windows to choose? If you plan to make the balcony a living room, two-chamber plastic windows with hinged doors. They are more airtight than sliding window systems, and such windows also have better heat and sound insulation properties. The only negative is that since the balcony area is generally small, the arrangement of furniture may interfere with opening the windows.

In general, you can install plastic windows yourself. But it’s better not to take risks if you don’t have experience: after all, even some companies specializing in window installation make annoying mistakes in their work. In order not to encounter would-be installers, frozen windows, etc., be sure to read the reviews of people who have worked with this or that company.

If installing new windows is still not possible, it is quite possible to find another way out. on the balcony easily using available materials.

Even a perfectly insulated balcony can be a little cool in winter. To make it comfortable for you to be on the balcony on the coldest days, ideal option There will be an electric heater. Usually it is placed near the wall separating the balcony and the apartment. You should not place a heater near the windows, otherwise the glass will start to fog up.

Conduct central heating You are not allowed on the balcony: this is prohibited by building codes.

Also good decision For heating there will be an electric heated floor or a water floor. Modern technology warm floors will delight you as long as the balcony itself lasts. Many systems are equipped with a thermostat, so you can set a comfortable temperature.

After you have done everything necessary work regarding insulation, care should be taken. If you have sealed all the cracks on the balcony, there will simply be nowhere for fresh air to come from. Therefore regularly

The process of insulating a room itself is very important, since with the help of such repairs drafts and cold are removed, and the space of the connected room expands. But it’s not enough to just install double-glazed windows and cover the cracks and holes with polyurethane foam. It needs to be insulated. To save money in your wallet, it is better to insulate the loggia with your own hands, step-by-step photo instructions presented in the article will help you do the work.

Amazing balcony with ecological materials

Initially, you need to select building materials. It is important to remember that not only thermal performance, but also may depend on the selected components. If the building material is too thick, it will steal the usable area.

Note! Any material for heat preservation must be environmentally friendly and also meet thermal and steam characteristics.

The room can be insulated with the following materials:

Penofol . An excellent substitute for mineral wool. It has a multi-layer coating, which also has a reflective effect.

Polyurethane foam . Ideally suited for balconies. It ignites very poorly and is made from environmentally friendly materials. Installation is done by pouring.

Expanded polystyrene . A fairly economical choice of material and also very effective for a balcony.

Izover . Available in sheet form. Made from mineral wool with fiberglass particles.

As a rule, polystyrene foam is mounted on the walls and ceiling. It is good to use because its properties have a high thermal conductivity coefficient, as well as a small thickness. It cuts great kitchen knife. Alternative option can be considered polystyrene. For cold winter Sheets 10 cm thick are suitable; for mild weather it is better to use 5 cm.

Do-it-yourself preparatory work and insulation of the loggia: step-by-step photo instructions

Before the main process, preparatory work should be done. Only then will you be able to insulate the loggia yourself, and step-by-step photo instructions will help with this. To do this you will need:

Select those places that will be precisely processed. In any case, you should definitely treat the parapet. The walls can be treated as needed. If there are no neighbors on the sides, then they also need to be covered with building material. Often all walls are insulated.
Before repairs, you need to take everything out and clean the surfaces.
It is recommended to replace the windows and install double-glazed windows if there are none.
Next, you need to lay the wiring for sockets, lamps and switches.
The next step is to select a material.
After selecting the material, you can move on to working with the floor, walls, and then the ceiling.
Upon completion, finishing work should be carried out.

Fastening for thermal insulation, can serve as adhesive composition, and dowels. If an adhesive composition is used, then during the work you will need to glue the gluing area and the material itself.

Helpful advice! The resulting seams, which are obtained directly during the insulation process, should be filled with polyurethane foam.

Penoplex and how to insulate a loggia with it

Many people dream of converting a balcony into a full-fledged room. But in order for the use of such a room to be comfortable, it will need to be insulated. As a rule, apartments have parapets thin walls. In this regard, on initial stage You will need to demolish it and lay it out again. Thus, the wall will be thicker, and therefore warmer. It is recommended to use a brick, which is placed on the adhesive composition with an edge. Sand-lime brick is ideal for such masonry.

After the fresh masonry has shrunk, you can begin installing the windows. To do this, it is recommended to use the services of professionals. Next, you can move on to insulation. will be installed on the ceiling, walls and floor. By following the instructions you can get started:

The prepared pieces should be placed in a frame. You can also not create a frame, but mount the slabs directly on the walls using special mounting mushrooms.

Helpful advice! The slabs should be adjusted so that they fit tightly one to one. This will get rid of the cracks, which means the loggia will be much warmer. It is recommended to apply polyurethane foam or sealant at the joints.

Reflective insulation should be placed on the walls, ceiling, and floor. Penofol is ideal. It is recommended to seal the joints with foil tape.

After this, the balcony will be ready for final finishing. To do this, you can use wood or plastic lining or install other panels.

We do it ourselves. How to insulate the floor on a loggia?

The floor should be treated first, and then all other surfaces. The work process looks like this:

It is necessary to thoroughly clean the floor from debris and dust.
Next, you need to seal all holes or cracks with foam.
Now you should use a thin one and place it on the entire floor. Lay it in such a way that there are no joints or there is a minimum number of them.
When the first layer is laid, you need to walk around its perimeter construction foam, including joints and seams. Then the second layer is laid in the same way.

Now you can mount the frame from wooden beam. The distance between the bars should be about 50 cm.
The resulting gap should be filled with polystyrene. The thickness of the insulation will depend on the thickness of the timber. Ideal when they are flush.
Next, you need to cut the penofol to the size of the balcony and lay it with the foil side up, but so that it protrudes about 20 cm onto each wall.
Now you can attach the floor boards to the beams and install the decorative covering.

As an option, the floor can be installed with a heated floor or the loggias can be made of penoplex.

Insulation of the ceiling and walls of the loggia

For almost all types of rooms, insulation of walls and ceilings occurs in the same way. Thus, the walls are insulated as follows:

For, polystyrene foam is best suited. The process is carried out by analogy with walls and floors.

Insulating a loggia from the inside: what is the best way to do it?

For selection the right material, there are some important factors to consider:

Purpose of the room.
- If the balcony will be used as a storage room, then you can use any building material, installing it in 1 layer.
- When the balcony turns into one room, it is necessary to use different building materials, which are laid in 2 layers over the entire area.
- If it is combined with a room, then you need to use two-layer insulation. The walls can be made in one layer, and special attention can be paid to the parapet.
Using insulation for interior decoration, effective area will be less, so this factor should be taken into account.

The choice directly depends on the described factors and tastes of the owner of the premises.

Finishing work

Finishing work is needed. This is not only due to aesthetic appearance, but also affects protective factors. If we're talking about O exterior decoration, then the parapet can be covered with corrugated sheets or siding.

Internal work can be anything. It all depends on preferences and imagination. But it’s worth noting that decorating the inside of the loggia with your own hands will bring More fun and joy. Often the work is done using PVC panels. You can also wallpaper or simply paint the walls. The loggia looks very good when decorated with wood. It will not only be beautiful, but also environmentally friendly.
