The formation of polyvinyl chloride windows into a full-fledged segment has long been completed in the domestic market. Technological and functional frames have confidently replaced their wooden counterparts, providing consumers with reliable and ergonomic glazing. However, plastic profiles for PVC windows also cause mixed opinions from users, which is due to the variety of models and quality parameters of these products. Often, the manufacturer's brand becomes the decisive selection criterion - certified windows are more likely to be endowed with the qualities and characteristics declared by the company. All that remains is to figure out which brand guarantees best properties profile.
What is a PVC profile?
A metal-plastic profile is a frame that can include up to eight chambers, but models with two or three compartments are more common. Actually, they generally depend on their parameters. It is logical that the options larger area weaker in insulating and soundproofing functions than plastic window profiles small sizes. In order to increase thermal insulation, manufacturers use polyurethane foam, which fills the space of the chambers. Fiberglass covering is also common. The list of main distinguishing features of profiles also includes installation width. The rigidity of the structure and, consequently, the reliability of the valves depends on these indicators.
Foreign profile manufacturers
For the most part, imported PVC windows are represented on the market by German products. Technologies of European companies have come far ahead and today dominate this niche. The list of companies numbers in the dozens, and the leading positions in quality and sales are occupied by the brands KBE, Rehau, Veka, Trocal, Deceuninck, etc. It is noteworthy that the windows of most German companies are manufactured in Russia under special licenses. Accordingly, many plastic profiles for PVC windows, the names of which are of German origin, are produced in our country. Domestic manufacturers of brands such as Rehau and KBE strive to ensure proper quality by completely recreating the original
Russian profile manufacturers
Despite the wide representation of foreign window products, Russian manufacturing technologies are also being improved. One of the oldest domestic manufacturers of metal-plastic profiles is the Proplex company. Having initially mastered Austrian technologies, the company strives to offer a wide range of glazing products.
The formation of the Montblanc brand was not without help from Austrian specialists. On this moment The company's clients have access to plastic profiles for windows with a maximum width of 120 cm - this is a system that includes five chambers.
The Novotex company, which has production facilities in the Moscow region, can perhaps be unconditionally called Russian. Engineers and technologists are constantly working to improve plastic structures, focusing on local climatic conditions. It is the latter factor, combined with a low price, that allows the Novotex brand to maintain competition.
Class A profiles
Although the quality of profiles is determined by general criteria, there is a division by class, according to which comparison of premium models and representatives of budget series is unjustified. The first ones obviously win performance qualities and durability, and the advantage of the latter is the price.
So, luxury plastic profiles for windows are positioned on the market as A-class. Such systems are distinguished by their wall thickness (3 mm), reliable connections in the corners, and protection from external influences. Technical features A-class profiles are not felt during use, which, however, indicates the reliability of the structures. They are very problematic to dismantle without special tool, created indoors optimal microclimate, and aesthetic beauty with the possibility of tinting the frames makes premium systems the best choice. Representatives of the A-class include profiles KBE, Rehau, Veka, etc.
Class B profiles
You cannot count on impeccable technical and physical parameters in the windows of this group, but due to the relatively low cost, this product also deserves attention.
The thickness of the outer walls in B-class structures is 2.5 mm. For this reason, plastic profiles for PVC windows of class B are less resistant to physical influences. There is also an opinion about the unsatisfactory environmental performance of profiles of this group, but this is not true. No toxicity is general condition certification of plastic structures.
Category C profiles
In general, modern C-class profiles fully meet consumer needs both in terms of sound and heat insulation, and decorative properties. Another thing is that premium competitors have raised the level of technical qualities quite high.
Representatives of category C include profiles of such brands as Vektor, LG Hausys, AGF, as well as almost all domestic products, including Novotex. As a rule, they are used to provide non-residential premises, but there are also lines aimed at installation in apartments and private houses.
Rating of the best profiles
Against the backdrop of development technological methods production of profiles and fierce competition are not easy to identify. The rating is formed based on a combination of qualities and the introduction of fundamentally new properties. In this regard, the arrangement of leaders can be presented as follows:
This brand has earned its championship by maintaining an unsurpassed level of basic qualities of window profiles. These include 50-year durability, increased heat and noise insulation performance, as well as environmental friendliness due to the inclusion of PVC connections zinc and calcium.
Constituting serious competition to KBE, the Veka brand takes second place. The list of its advantages includes the technology of manufacturing “light” profiles, which at the same time ensure the preservation of heat and acoustic comfort.
3.Rehau
Rehau is rightfully among the top three. The quality of the profiles of this manufacturer is achieved through the introduction of lead compounds. As a result, the structures acquire high strength and stability in operation.
The following positions can be occupied by many plastic profiles for PVC windows. Which one is better among them should be determined by the same parameters. The Salamander and Deceuninck systems should be added to the top three. Although plastic profiles for windows of these brands are not so popular, their physical and technical qualities maintain a high level. They are also distinguished by ergonomics and thoughtful configuration, which facilitates installation and further use of window systems.
Loud slogans from numerous sellers plastic windows confuses any buyer. Each manufacturer presents their products as the best. Is it really? The answer to this question is known to those who are familiar with the criteria for window profiles from.
The ability to notice the first signs of counterfeits is a guarantee of not becoming a prey for scammers.
They have entered the construction industry very firmly. Very soon, wooden windows will become a curiosity that you won’t see very often. And there are explanations for this.
Advantages of plastic
Firstly, plastic is more cheap material than wood, secondly, it is convenient to use and thirdly, such windows are very easy to repair.
Replacing any part of a window: sash, glass, opening mechanism takes a couple of minutes, and therefore is inexpensive.
Technical characteristics of PVC windows
They are determined by the type of its profile, of which there are quite a lot. The facade of the windows may be exactly the same, but the functionality and quality are different, due to the structural profiles. Then, if there is a strong intention to purchase plastic windows, then which profile is better to choose?
Brands
Absolutely disgusting products from a company with famous name can't afford it. Most likely, these will be one-day companies.
Therefore, give preference to products from manufacturers who have experience and have collected a list of positive reviews. In addition, the risk of stumbling upon a low-quality product when choosing windows from a large factory is much less. Expensive productive and technological equipment small firms are unlikely to purchase.
REHAU windows
Very famous manufacturer plastic windows. Well-deserved reviews, minimum defects, constant training and improvement of our employees, innovative development of manufactured designs. They cooperate with enterprises only if the latter have good equipment.
Interesting! REHAU certified production facilities are constantly inspected. Therefore, the risk of buying a low-quality product from the hands of a company partner is very small.
VEKA
Also a representative of the German ones, loved all over the world. They produce white and colored profiles that are capable of not losing color during prolonged exposure to sunlight.
The seal is made of natural rubber and can withstand very low temperatures. Models are sold from 58 -90 mm thick. IN price category VEKA and Rehau are approximately the same.
KBE
It ranks third in our ranking after the first two companies. There are minor drawbacks: the number of defects is slightly higher compared to previous giants, there may be delays in deliveries, they do not arrange checks for their partners.
However, the products of this company are considered environmentally friendly and are recommended for installation in kindergartens and hospitals. The service life of such windows is around 50 years. There are offers in both luxury and economy classes. The profile is available in widths from 58 to 70 mm.
Trocal
The company is one of the pioneers in PVC production profile. They offer a huge range of decorative options.
MOTNTBLANK, PROPLESS, BRUSBOX
These companies are still gaining their reputation. There are already reviews of their products on the Internet.
You can even choose a forum and ask the owners of such windows your questions. The main advantage here is the affordable price.
Which profile is the best for plastic windows? The hundreds of manufacturer names in search results and on storefronts make your eyes widen. Not to mention the technical descriptions, which you can’t figure out right away, the advantages (of course, not a single manufacturer will write about the disadvantages), consumer ratings, rating tables... So that you don’t have a headache again and the search is crowned with success, let’s figure out what a double-glazed window is , why there are 2 or more cameras in it, what the optimal profile for windows should be and what fittings are best to use.
Before we investigate our case about the choice of plastic windows, let's reveal a little secret: often extolled by sellers German windows In fact, they turn out to be of domestic production. Hence our advice - do not rush to give preference to flashy statements from manufacturers about products from Europe; it is better to choose official representatives of foreign brands in our country who comply with foreign standards in production.
Let's define it in terms: what is a double-glazed window and what is a profile?
When choosing plastic windows, you should understand what lies behind the words “double glazing” and “profile”. In the first case, we mean a design of 1-2 glasses with one or more chambers (gaps between the glasses). The second concept refers to a frame, which consists of several chambers separated by PVC partitions. Externally, the profile resembles a hollow one plastic mold with solid metal frame for better durability.
Which double-glazed window is better - double-chamber or multi-chamber?
Glass occupies 85% of the window opening, and the strength and quality of the plastic window as a whole largely depends on its properties. Double-glazed windows can be single-chamber or double-chamber, sound-absorbing, sun-reflective, energy-saving, etc.
Single-chamber ones are recommended for glazing balconies and loggias. For residential premises, it is better to choose double-chamber and multi-chamber double-glazed windows with energy-saving glass, the main principle of which is reflection in winter period heat in the room (like a thermal mirror).
We cannot advise anything specific, since all profiles are selected individually based on the functions required of them. Compare the options for double-glazed plastic windows from REHAU:

How to choose a profile for plastic windows?
There are a great variety of branded window profiles; the knowledge and experience of specialists is invested in the production of each of them, and this is definitely one of the indicators of quality products. However, let's get back to the matter at hand: how do you know which window profile will be best for you? The answer is simple: focus on climate zone, cost and Additional requirements. For example, if your apartment is located in the Moscow region near a road, and your house is in Siberia, then for one and the other housing you will need different types windows
In the first case, we would advise relying on heat retention, noise insulation, burglary protection, offering a standard profile at a low price and premium options for best result(returning to the example above, these are Rehau Blitz and Rehau Delight Design).
In the case of glazing a house in Siberia, it is better to focus on heat preservation and resistance to frost (these are Rehau Sib-Design and Rehau Brillant-Design).
Another parameter that experts advise you to pay attention to is the width of the window profile. The best option for apartments and country houses- width 70 mm, number of air chambers in the profile itself - from three, profile wall thickness - from 2 mm. All of the listed window parameters allow you to keep rooms warm in winter.
A few words about accessories
Because the average term window service life is equal to the minimum service life of a residential building (40 years), then the fittings on it should not oxidize, rust or break. To avoid any incidents, when choosing a plastic window, give preference to products made of stainless steel, nickel-plated and handles covered with plastic.
The hinges must be hidden to avoid the slightest leakage of water in the rain, with a double seal.
Let's summarize - which profile to choose in 2018
In conclusion, a short excerpt from the text and additional tips optionally.
- A company for the production and installation of windows should be chosen carefully: pay attention to the official representatives of European brands whose production is located in Russia; the length of time the company has been operating in the sales market in the region; Availability of licenses and certificates for products.
- When choosing a double-glazed window and profile, be guided by the basic needs during operation. Decide which parameters are most important to you: thermal insulation, noise absorption, solar reflection, energy saving, design, profile smoothness, presence of seals, ease of cleaning, etc. Based on the results obtained, proceed to make a choice or request from consultants.
- Do not skimp on fittings - they should last at least 40 years. Choose from stainless steel, nickel or plastic plated options. It is better if the hinges in the design are hidden.
- Pay attention to the design of the final product and the possibility of decorating it to match the style of the facade and interior of your home.
If you have any questions or want to learn more about the selection criteria, you can always seek advice from specialists:
Installing PVC windows instead of old ones wooden frames, apartment owners want to protect their home from cold, dust and noise. Therefore, choosing profile types for plastic windows is a serious task.
Modern PVC windows add coziness to the room, long years retain their original appearance. They are easy to clean, quick to install and perform the above functions better.
How to choose the right profile for plastic windows, how does quality compare with the manufacturer’s brand and the price of the product?
The profile in a plastic window is the basis of the structure. The doors are made from it, double-glazed windows are installed, and framed with fittings. The choice of PVC profile affects the characteristics of the window structure as a whole - the ability to sound insulate, seal and retain heat in the room. An important aspect of choice is types exterior design window frame.
Profile structure and material
A plastic window frame is a complex design. Its cross section makes it possible to see many air chambers inside the structure that retain heat. Naturally, the more chambers, the better the thermal protection.
A metal frame (reinforcement) is inserted into the PVC base. It ensures the strength of the profile and is the key to maintaining its shape when the plastic is exposed to rain, wind and frost.
Polyvinyl chloride (PVC) is a material for the manufacture of plastic windows.
Main characteristics:
- does not oxidize in air;
- not afraid of moisture;
- does not collapse from extreme heat;
- harmless to human health;
- washes better than a wooden frame;
- has a large color scheme, but is mainly used in white. But you can choose and order “wood” or marble lamination.
The profile type should be selected in accordance with the conditions in which it is intended to be used. If winters are windy and frosty, you need to choose a chamber with a large number of air compartments and thick double-glazed windows. But there should not be less than three air chambers in the frame.
PVC profiles are classified into three types - economy, standard, luxury. The most popular and well-proven types today are the German profiles of the brands “Rehau”, “Veka”, “KBE” and “Trocal”. You need to choose profile types carefully. Special stickers on branded products indicate their quality and authenticity.
The production of high-quality plastic for the manufacture of windows has also been established in Russia. These are PVC profiles “Novotex” from the Moscow region, “Exprof” from Tyumen. These are cheaper models. The Montblanc brand is resistant to temperature changes and severe frosts.
The rigidity of the frame depends on the thickness of the reinforcement in the profile. It is made of a galvanized steel liner and can be closed or U-shaped. It is a cold profile element.
Window installation
It is not enough to choose a high-quality PVC profile. It is necessary to professionally install a structure made from it to avoid freezing, condensation on window glass and drafts. This work is performed by measurement and installation specialists who know many of the features and subtleties of installation in various types houses. Here it is necessary to take into account the choice of material, the thickness and structure of the walls, accurately calculate the size of the frames, install them strictly horizontally and securely fasten them in the wall. Cavities and cracks are filled polyurethane foam to prevent air from entering, the installation seam is plastered on the street side, and on the inside the installation seam is sealed with slopes.
Certification
The PVC profile certificate provides complete technical information about it. Not all subsidiaries of companies with advanced brands have the right to issue such a document for their products. This means RAL certificate.
Manufacturers VEKA, REHAU issue such a quality certificate at all enterprises, including Russian factories in the Moscow region and Novosibirsk. Consumers try to choose products with such a certificate. The certificate guarantees compliance with technologies in the production of frames and high quality of the source material. It's a good choice.
How does profile width affect structures?
The degree of stability and thermal insulation of frames depends on the choice of width plastic construction. What size does it come in:
- The profile with a thickness of 58-60 mm is used for glazing residential, small office premises, and balconies.
- A 70 mm profile is installed in country houses, when insulating loggias.
- 80 mm frames are used for windows in high-rise buildings.
- A maximum profile width of 90 mm is used in frames in northern latitudes for improved thermal insulation.
The profile with a thickness of 58-60 mm is the most popular among others. We recommend choosing it for installation in an apartment, as it is easier to install and meets the requirements for home windows.
Installing a window with a profile of maximum width will cost more, but we remember that the coldest place in the window is the double-glazed window, so we focus on the maximum width of the double-glazed window, adding energy-saving glass and an external glass of 6 mm, which will pay off in a short time due to heat energy savings and noise insulation.
Number of cameras in profile
Thermal conductivity and sound insulation ability depend on the thickness of the frame profile. It is determined by the number of air chambers in the structure. There must be at least three of them. The first is used to remove condensate, reinforcement is inserted into the second, and the third chamber additionally insulates. The most popular and widely used model, 58-60 mm thick, has three air chambers. In thicker frames there can be from four to six.
It is important to note! The thermal insulation characteristics of the profile do not depend on the number of partitions, but on the size of the air chambers, that is, on the thickness of the frame. The thicker the frame and the glass unit on it, the heavier the structure. This requires quality professional installation.
Classification of profiles by camera type
Plastic structures only appearance similar. Used for different purposes special types ram. After all, not only windows are made plastic, but also entrance and interior doors, indoor partitions, balcony groups and so on. The functions and thickness requirements for such frames are different. Which of the two types should you choose?
“A” class - a profile with thickened external walls. This type is used both for glazing windows and for installing doors and frame partitions.
“B” class - lightweight profile with a thin outer wall. This cheaper option is "object based". The budget price attracts buyers, but we must remember that thin plastic walls cannot always cope with the tasks assigned to them.
The quality and rigidity of the profile depends not only on the material - polyvinyl chloride, not only on the size, but also on the number of air chambers. The joints of the profile parts in the corners must be strong, withstand temperature loads and be resistant to mechanical stress. The quality of the connections provides an additional resource for using profile frames. In pursuit of a favorable price, it is important not to lose the quality of the product.
Each company, in addition to the certificate, accompanies its product with a warranty. If the corner fastenings are weak, then the finished window base may lose its shape over time or the corners may separate. The service life of the product will decrease and depressurization will occur. Such windows will not retain heat, the glass will fog up, and condensation will accumulate on the windowsill.
Leaders in production
Plastic windows have gained popularity; they are installed in offices, residential premises, and industrial facilities. A certain list of leading companies producing profiles has been compiled.
- The most best rulers profile systems are produced by Rehau, Veka, as well as Trocal and Salamander. This is plastic of the highest quality, the production of structures is carried out in compliance with all technological standards. And as a result of this, the quality of windows and other structures made from this material never raises any complaints from installers and consumers. The price for the types of profiles of the listed companies is quite high. But this choice is justified for a long time construction services.
- Quite high-quality profiles for windows are made by Aluplast, Funke, Artek, Proplex and KBE.
Summing up the analysis of the quality of window profiles, we can say that the most the best choice- these are frames from well-known brands in Russia. They are reliable and of good quality. Width optimal options are 58mm and 70mm profiles. Based on the number of air chambers, it is better to buy three-chamber structures. Such windows are not very heavy in weight and are affordable. Pay attention to the surface - glossy ones are easier to clean. Seals must be replaceable.
It is better to entrust the selection of design components and installation to a specialist who is responsible for the quality of the choice, work and carries a guarantee.
Plastic windows firmly occupy a leading position. They differ high level heat and sound insulation, and also provide the opportunity to choose fittings, window opening method and profile color. You can also choose a double-glazed window with required quantity cameras But few people think that it is the window profile that ensures the strength and durability of the entire structure. In this article we compare plastic window profiles with different characteristics and manufacturers.
General information about the profile of plastic windows
On average, the profile thickness of plastic windows varies from 58 mm to 86 mm, but some companies produce products up to 127 mm wide.
Its interior is hollow, but is divided by bridges that create several air chambers. A special technical calculation determines their dimensions and location. The wider the profile, the greater the number of chambers in it, increasing the heat-saving properties. Another characteristic of the profile system is the filling width, which determines what type of double-glazed windows can be installed in the profile. They come in single- or double-chamber types, the width of the glass in a standard double-glazed window is 4 mm (grade M1).
Each cavity has its own purpose:
- for water drainage;
- fastening accessories;
- responsible for strength, etc.
The color of the profile can be varied; painting is applied in several ways:
- coextrusion method - multilayer films create a kind of barrier that allows the product to withstand dynamic loads without damage;
- lamination - with imitation texture, for example, marble or wood;
- monochromatic coloring.
Characteristics of PVC profiles for plastic windows
Material
- This product is made from a type of plastic - white polyvinyl chloride.
- The material is highly resistant to chemical attack by alkalis, solvents, acids and mineral oils.
- It is harmless to humans and the environment.
- Due to its distinctive properties, polyvinyl chloride makes it possible to produce frames for double-glazed windows not only in rectangular or square shapes, but also in the form of arches, triangles, circles, and so on. Thus, giving absolutely any simple or complex configuration to the window, allowing even the most unconventional idea designers and architects.
Design
The inner part of the plastic profile body is divided by longitudinal partitions, in turn they form cavities (air chambers). The minimum number of chambers in a profile is 3, the maximum is 8. The number of chambers determines the degree of thermal insulation and sound absorption of the window; the more air cavities, the higher these indicators. It should be noted right away that 3- and 5-chamber profiles are popular.
Reinforcement
To provide rigidity, the profile is additionally reinforced. Metal carcass provides the necessary structural strength and reliability during operation of the window. Galvanized steel is used to reinforce the profile, so it does not deform due to temperature changes or other environmental influences.
- L-shaped type of reinforcement - a metal insert is installed along two walls;
- U-shaped type of reinforcement, where metal strengthens three walls;
- Closed type of reinforcement - a metal insert is located along four walls.
For window structures that have double-glazed windows up to 1900 mm in height, a U-shaped reinforced profile is suitable. However, for plastic windows of large dimensions, for example, for a loggia or balcony, a profile with closed reinforcement is required.
Profile class
The thickness of the profile walls determines whether it belongs to a certain class:
- Class A - the thickness of the profile walls must be at least 3 mm;
- Class B - profile where the wall thickness is from 2.5 mm;
- Class C - non-standardized wall thickness.
As a result, the width of the profile of plastic windows directly depends on its class. The higher it is, the correspondingly wider the profile.
Comparison of manufacturers of plastic window profiles
Many people, both domestic and international, present their products on the Russian market. foreign manufacturers. The leading positions in the ranking of profiles for plastic windows are occupied by the following companies:

You can also compare the characteristics of plastic window profiles using the tables below.
Profiles of the German company KBE
It is believed that German profiles of plastic windows are superior to the products of other manufacturers in terms of quality, whiteness of color, and technical characteristics. They do not lose their properties even over a long service life and can withstand almost any dynamic loads and significant temperature changes (from -50°C to +50°C).
The KBE company produces and supplies 2 types of the most popular profiles: KBE Etalon and KBE Expert.
KBE Etalon - three-chamber profile
- The installation width is 58 mm;
- width of front walls - 3 mm;
- the thickness of the glass unit can be up to 34 mm;
- 3 chambers in the frame, sashes, impost (horizontal and vertical window bars);
- can be used in harsh conditions (-60°C);
- service life - 40 years;
Advantages:
- with a profile width of 58 mm, it has 3 air chambers, their size and optimal position provide heat transfer resistance. Such windows have high degree tightness, which exceeds the existing GOST requirements by 5 (!) times, which guarantees the complete absence of dust and drafts in the room;
- two sealed sealing gaskets provide excellent sound insulation (up to 46 dB). The profile is additionally equipped with horizontal lintels, thereby increasing the strength of the lock when closing the window;
- The KBE profile has stiffening ribs that provide additional strength to the window structure. Also, special stops can increase rigidity, with the help of which the precise location of the reinforcing metal insert is achieved.
KBE Expert - five-chamber profile
- Installation width is 70 mm;
- width of front walls - 3 mm;
- glass unit thickness is up to 42 mm;
- 5 chambers in the frame and sashes, 3 or 4 in the impost (horizontal and vertical window bars);
- Suitable for use in harsh conditions (-60°C);
- sealing contours correspond to class A;
- service life - 40 years;
- Environmentally friendly materials are used in production and do not contain lead.
Advantages:
- The five-chamber structure allows for better thermal insulation values; this profile is capable of retaining heat 20% more than typical three-chamber systems. You can achieve excellent sound insulation by installing wide double-glazed windows with a 70 mm profile;
- The 13 mm groove of the profile allows you to install anti-burglary fittings, thereby ensuring the security of the room;
- the KBE Expert profile has additional horizontal jumpers, thanks to which the handles and hinges will be securely fastened;
- When installed, the mounting seam becomes approximately 20% wider, in turn allowing for additional insulation.
Estimated cost of windows from KBE profile
An important factor when choosing a particular double-glazed window is its price. It is often decisive, but high quality German window profiles cannot be cheap. Below is an example market price across Russia.
- On average, a single-chamber double-hung window with dimensions of 140x130 cm, in which one sash is fixed and the other is tilt-and-turn, will cost:
- from a 58 mm profile from RUB 7,500,
- from 70 mm - from 10,000 rub.
- The price of a two-chamber three-leaf window measuring 140x203 cm, in which the first sash is rotary, the central one is blind, and the third is tilt-and-turn, will range from:
- from 58 mm profile 13,000 rubles;
- from 70 mm 14500 rub. and higher.
- When purchasing a balcony block with an opening door measuring 210x67 cm and a blind window - 140x136 cm, you will have to pay at least:
- from a 58 mm profile 11,000 rubles;
- from 70 mm from 13,000 rub.
What to look for when choosing a plastic profile with double-glazed windows
In order to determine what profile thickness is needed, you should have basic knowledge about the double-glazed window, because up to 70% of heat losses occur through it.
This transparent element consists of 2 or more glasses that are tightly connected to the frame. A chamber (air gap) is formed between them, filled with rarefied air or inert gas, such as argon or krypton. This kind of filling is used in the production of energy-saving double-glazed windows.
A single-chamber double-glazed window is a design of 2 glasses of 4 mm each and air gap 16 mm, abbreviated as 4-16-4. Thus, its installation width is 24 mm. The design, equal to 36 mm, is obtained from a two-chamber double-glazed window, which consists of 3 glasses of 4 mm each and 2 layers of 10 mm each - 4-10-4-10-4.
Consequently, an appropriate profile is selected for the required double-glazed window. For example, optimal solution For ordinary apartment or at home, a 5-chamber profile with a 70 mm installation width and a 30 mm double-glazed unit will serve, where a heat-reflecting coating should be applied to one glass.
If the windows face north side and there is a road busy with cars nearby, then in this case the following option is suitable: a 5-chamber profile with a depth of 86 mm, complemented by a 32 mm double-glazed window with a protective noise-insulating film.
When a balcony (loggia) is combined with an adjacent room or it is planned to make a small office (rest room) out of it, then the profile should be 5-chamber with an installation depth of 86 mm, and the double-glazed window should be energy-saving, two-chamber with a width of no less than 40 mm.
For simple insulation of a balcony, a 60 mm 3-chamber profile and a 30 mm single-chamber double-glazed window are suitable.
But it’s not enough just to choose the optimal PVC profile and double-glazed window. It is equally important to entrust the installation of the finished window to professionals. Otherwise, no matter how expensive the design, poor-quality installation will cancel all its high characteristics.
