Currently, in the Russian market of window products, despite the increasing number of sales of wooden and aluminum structures, plastic windows remain the leader. This is facilitated by a lot of advantages that PVC products have. The main ones, of course, are excellent heat and sound insulation, long service life, and the possibility of using additional accessories that increase the functionality of the window ( mosquito net, thermometer, etc.), as well as a great appearance coupled with an affordable price.

As you know, the basis of plastic windows is the profile. In the entire light-transmitting structure, its share accounts for approximately 10% of the total area of ​​the product. The remaining 90% is occupied by double glazing.

It is no secret that all PVC profiles included in the windows sold are the same. To pick up best option, which would fully meet the requests for appearance, level of sound and heat insulation, as well as price, the buyer needs to have an idea about each element of the window and be able to freely operate with technical terms associated with each of its components.

In this article we will take a detailed look at the main points that you should pay attention to when choosing a window profile, describe its design, and explain the meaning of basic technical terms.

How many cameras should a plastic window have?

The image is clickable.

When considering the characteristics of the light transmitting model you are interested in PVC structures, Special attention Three points should be taken into account:

• profile;

Most significant characteristic profile is its chamberness, that is, how many chambers it consists of. Their number directly determines how well the plastic profile retains heat.

Profile with three cameras. For residents of regions where cool weather conditions reign most of the year, the most preferable option is a three-chamber window profile. Three chambers reliably protect the structure from blowing, which means they perfectly retain heat in the room. In addition to this, they have a built-in metal frame designed to strengthen the plastic sidewalls. Three-chamber profile plastic window, as a rule, has a width of 5.8 cm.

Profile with four or five cameras. Products that contain four are either intended primarily for use in areas of the country in which the summer season is not long, but temperature conditions clearly leaves much to be desired. The protection provided by a profile with such an increased number of chambers copes with even the lowest temperatures (30 C and below). Therefore, inside the room, glazed with windows with a multi-chamber profile, it will be warm and cozy in any weather. It is worth noting that the use of such windows in warm regions of the country is little justified due to: mild weather conditions; prices that significantly exceed the cost of their three-chamber “brothers”.

Single-chamber and double-chamber profiles. They are mainly used for glazing apartments and private houses located in the southern part of Russia. A design flaw that prevents them from low temperatures their ability to efficiently retain heat is more than compensated for by their price - it is significantly lower than the cost of plastic window models, the profile of which has a larger number of chambers.

As a result. If you need maximum protection from the cold, opt for plastic window models with a 4 or 5 chamber profile. If there is no need for maximum heat conservation in a glazed room, for example, in the southern regions of the country where hot weather prevails, one- or two-chamber PVC structures should be chosen.

For most buyers the best solution for the home there will be the purchase of three-chamber systems.

Criteria for selecting a profile, depending on its thickness.

Sectional profile. Click to enlarge.

Not unimportant characteristics of PVC profile is its thickness. It depends, first of all, on the number of chambers and indirectly speaks about the ability of a window to retain heat: the wider the profile the warmer it is, as a rule.

When choosing optimal width profile of a plastic window, it is necessary to take into account that there is only a large number of options, from which the following should be highlighted:

58 mm. The profile, 5.8 cm wide, is the most popular in the Russian window market. Compared to other, thicker brothers, it stands out due to its low price and fairly tolerable characteristics. As they say - cheap and cheerful. However, if the buyer pursues the goal of glazing a window opening without pretensions to super-results, then plastic window models with a 58 mm profile will fully satisfy his desire.

70 mm. The profile width of 7.0 cm allows the product to accommodate from 3 to 5 cameras. This thickness is more than enough to provide the glazed room with the appropriate level of heat and sound insulation.

90 mm. The widest profile option for PVC windows, which best copes with the issue of heat retention in the apartment. Contains up to 6 cameras. The main disadvantage of this 9.0 cm solution is its price, which is significantly higher than other similar products that have a smaller thickness.

There are also designs whose profile width is quite impressive 110-130 mm! Such windows are also called “Danish” or “Dutch”. They are, so to speak, designed for the amateur.

Cross-section of a double-glazed window.

A double-glazed window, as mentioned above, occupies about 90% of the area of ​​the entire window. Today, there are three types of double-glazed windows, differing in the number of glasses installed in them:

• Single glass option. Not suitable for installation in residential buildings due to the presence of insufficient characteristics of such a double-glazed window. The main flaws in the design of single-glazed windows are poor heat retention, as well as the lack of protection from. With the onset of the cold season, such disadvantages can contribute to the cooling of the room, as well as the formation of an impressive layer of ice on the glass.
• Double glass design. Represents the most optimal solution for installation in an apartment, or a private house due to the good price-performance ratio. The so-called heat loss is practically eliminated, and heat in a glassed room is retained much better than when using a double-glazed window that contains only one glass.
• Three glass solution. With installed triple glazing, you can achieve not only the greatest heat savings, but also maximum protection of the apartment from all kinds of noise entering its territory from the street. Triple glazing has only two disadvantages - high cost and.

From the above information it follows that for most buyers the best option There will be a purchase of double-glazed windows, which will contain three glasses. If you lack funds, you can opt for double-glazed windows, which have the best price/quality ratio.

Selection of profile depending on manufacturer and class.

When choosing a suitable window profile, in addition to its characteristics, you should take into account its brand and class. Regarding the manufacturers of this type of product, it can be noted that today on the domestic window market you can find a fairly large number of brands that produce various models of plastic windows, differing in their constituent elements and, accordingly, characteristics.

Important! This issue was covered most fully in our previous materials entitled “” and “”.

Now a few words about choosing a profile class. There are two classes of such products:

Profile class A can be used both in residential buildings and geometrically complex facade structures. It has a long service life and has a wall thickness of at least 3 mm.

Class A profile. Click to enlarge.

Due to design features Class B profile is usually considered a budget solution. The main factor influencing the price is the presence of a thin wall of the product. It is precisely because of the savings on the thickness of the material used for the chamber wall that manufacturers of PVC profiles class B were able to keep prices for their products extremely low. Price comes at a price, however, the buyer should remember that such a marketing ploy cannot but affect the service life of a plastic window equipped with such a profile - the service life of the system will be significantly shorter.

To summarize all of the above, I would like to draw attention to the complete obvious fact: all elements of a plastic window are interconnected. When choosing a warm double-glazed window, you should also take care of purchasing a warm window profile. Otherwise, the design, due to the significant difference technical characteristics, may turn out to be unbalanced.

“Which window profiles are the best?” – a question asked by everyone who wants to finally install energy-saving windows in their home. However, despite the external similarity of all structures, inside all the profiles are completely different, some of which do not at all comply with SNiP RF and are not recommended for installation in residential premises. First of all, when choosing a window system, you need to pay attention to the number of chambers and the thermal resistance coefficient (the higher, the better). The next important parameter of PVC windows is the provision for reinforcement - this increases the load-bearing characteristics of the structure, helps to increase the service life of the system and its resistance to plastic deformation. To make it easier for the buyer to decide on a quality window system, this rating was compiled. So, TOP 10 the best companies and window models PVC profiles:

aluPlast

Aluplast opens a rating of window profiles by quality. The company provides a good range of technical solutions for window systems. The latest developments that increase the energy efficiency of structures are embodied in the AluPlast energeto series. The Energeto 8000 model has excellent thermal resistance when installing triple glazed windows - 1.27 m2*C/W. According to the manufacturer, if the structure is not reinforced with steel (this reduces the load-bearing capacity), its thermal conductivity is significantly reduced, reaching a thermal resistance coefficient of up to 1.67 m2*C/W.

Deceuninck

Deceuninck is ranked 9th in the ranking of PVC profiles. The Belgian company has been producing window blanks from polyvinyl chloride for about 40 years at production facilities located in Europe, Asia and North America. The flagship of all Deceuninck lines is the 84mm Eforte model. This system recommended for installation even in the northern latitudes of Russia due to the high coefficient of thermal resistance - 1.1 m2*C/W. The service life of Eforte is 30-40 years, subject to a temperature range of -60 to +75 degrees Celsius.

Proplex

The Russian company Proplex takes 8th place in the ranking of window profiles in 2018. All Proplex products are manufactured in Russia, so prices finished goods from this profile is much lower than imported analogues. Proplex produces 5 different window systems: 2,3,4,5-chamber. For installation in dachas, loggias and non-residential premises, we recommend the two-chamber Proplex Outline - the most cheap design with a thermal resistance coefficient of only 55 m2 * C/W. More reliable system Recommended for installation in apartments and residential premises is the four-chamber Proplex Comfort with a thermal resistance of 0.8 m2*C/V, which fully satisfies the requirements of SNiP of the Russian Federation.

Kaleva

The seventh place in the ranking of PVC window profiles is occupied by the Kaleva brand. The company produces a dozen various models each of which has its own advantages and disadvantages. The most inexpensive option with everything you need is Kaleva Standard - it is a four-chamber profile with the possibility of reinforcement with steel and a built-in double-glazed window filled inert gas argon, which has very low thermal conductivity. The Kaleva Titan Plus five-chamber window system is the company’s most heat-saving and noise-reducing design. Feature of Titan Plus: in addition to the main two-chamber 40mm insulation package filled with argon, blinds and another external glass are built into the system - thus, this model provides a degree of insulation incomparable with other analogues, thanks to the insulation package with three independent air partitions, two of which are filled with argon.

Montblanc

Montblanc (pronounced MONBLAN) occupies a leading position in the 2018 ranking of plastic profiles for windows in terms of price-quality ratio. Mont Blanc is an Austrian company that has been producing low-cost, high-quality profiles for translucent structures for more than 15 years. Due to the opening of the Mont Blanc industrial plant in the Moscow region in 2001, the company gained wide popularity in Russia. The company produces several lines of window systems: Montblanc, Reachmont, Goodwin and ECP. All products have a guaranteed service life of 40 to 60 years, and an installation width of 58 to 70 mm, except for the eighty-millimeter Montblanc Grand with six air compartments. We recommend the four-chamber Montblanc Quadro system for installation with a thermal resistance coefficient of 0.8 C/W per m2 - this is a high indicator that meets the requirements of GOST and Building codes and rules in many regions of the Russian Federation.

Salamander

The TOP 5 rating of profiles for plastic windows in 2018 is opened by one of the most expensive brands in the rating. The company has three different systems in its product range: Salamnder 2d/Streamline/BlueEvolution. Most budget option is considered a three-chamber 2D with the possibility of reinforcing the internal chambers with steel. The wall thickness of Salamander 2D is: outer 3mm, rebated 2.5m, and inner 1mm - this ensures good indicator noise reduction (up to 46dB) and high energy efficiency class A+. This model is designed for installation of single-glazed windows. Salamander BlueEvolution is the next model recommended for installation in any region of Russia. BlueEvolution is the only profile available on the Russian market (meaning at a reasonable price) with a maximum width of the built-in double-glazed window - 60mm (if desired, you can install a three-chamber double-glazed window). Salander BlueEvolution is ideal for the continental climate of Russia: it protects from heavy rains, effectively maintains the temperature even at -40 degrees, and reliably resists drafts, thanks to the elastic rubber seal.

KBE

4th place in the rating of PVC window profiles belongs to the German manufacturer KBE. The names of the KBE rulers are banally simple and depend on the profile width: KBE 58/70/76/88. As anyone who plans to replace windows should know, the wider the system, the more chambers it has, which means that the heat-saving indicators of such a design are obviously high.

The optimal option for installation is the KBE76MD model - this is a six-chamber design made using greenline lead-free technology from recycled polyvinyl chloride. Recycling PVC allows you to “kill” two birds with one stone: recycle PVC waste and save on the cost of raw materials, which directly affects the retail price of the product.

The most important thing in greenline technology from KBE is the complete preservation of the physical and mechanical properties of the material, that is, primary processed raw materials are no different from recycled materials. The best product from KBE is considered to be the 88 mm KBE AD made using greenline technology: this model has an outer wall thickness of 3 mm and 6 independent air compartments inside with the possibility of aluminum reinforcement - all this provides an absolutely high level of thermal efficiency and noise reduction.

VEKA

The bronze medalist in the ranking of the best PVC window profiles goes to VEKA. VEKA offers 8 class A models with an outer wall thickness of 3mm. The most economical solution is VEKO Euroline: a design with three air chambers designed for glass units up to 24 mm (usually two glasses - one chamber), the sashes and frames of which can be reinforced for greater system reliability.

The optimal solution in terms of price and quality for offices and apartments will be the energy-efficient A++ class VEKO Swingline series: 5 independent air chambers with an outer wall thickness of 3 mm will ensure warmth and comfort in the room even on harsh winter evenings. The most expensive and massive specimen is VEKO Alphaline. This model is equipped with six air compartments with a total width of 90mm - these are the most heat-saving windows from VEKO in which you can install double-glazed windows up to 50mm thick (3 glasses) and enjoy peace and comfort all year round.

WDS

WDS ranks second among the best profiles for plastic windows in 2018. The manufacturer has several product lines in its assortment, each of which differs in noise reduction coefficient, heat saving and the number of cameras: WDS 400/500, WDS 4/7/8 Series. The optimal price-quality ratio is the Class A 60mm WDS4 model, equipped with 4 independent air chambers and the possibility of aluminum reinforcement up to 1.5mm. For northern latitudes, it recommends installation of the WDS8 series: a six-chamber metal-plastic profile with the ability to install a two-chamber double-glazed window up to 44 wide - this model retains heat 2.5 times more efficiently than the WDS400/4Series.

Rehau

Rehau is the leader in the rating, the best profile for plastic windows in 2018. The company's product range consists of 7 types of profiles with different numbers of air chambers, design widths and levels of sound insulation. The Rehau Euro-design series is an affordable and high-quality three-chamber profile with a thickness of 60mm, so it is recommended for installation by those who do not want to overpay. For lovers good sleep Rehau Intelio will be a real find: a five-chamber profile 86mm thick with a noise reduction coefficient of 36dB (without double-glazed windows).

In cold conditions climatic zones, 86 mm Rehau Geneo will help save up to 80% of heat: the six-chamber design ensures high tightness, maintains a colossal gap between the temperature amplitudes in the room and outside the window, and also creates reliable protection from drafts, thereby maintaining comfort and coziness in the room throughout the winter, even at -60 degrees. According to the manufacturer, all Rehau products have a minimum service life of 40 years, and some models even 60 years.

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 the consumer 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 the best profile properties.

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 profiles for small windows. In order to increase thermal insulation, manufacturers use polyurethane foam, which fills the space of the chambers. Also common fiberglass covering c In the main list distinctive features profiles and installation width are indicated. 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 according to 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. Currently, 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, perhaps, can 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 into classes, according to which comparison of premium models and representatives of budget series is unjustified. The former obviously win in performance and durability, while 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 a special tool, an optimal microclimate is created in the room, 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 window profiles PVC grade 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 in 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 support high level. They are also distinguished by ergonomics and thoughtful configuration, which facilitates installation and further use of window systems.
