The best profiles for plastic windows - review, reviews, recommendations. What are plastic windows and what products are of the highest quality? The best plastic windows

Probably, no one needs to prove that plastic windows with double-glazed windows have long and firmly taken a leading position in the competition with old wooden frames in terms of their performance. Advantages - in almost all respects, from thermal conductivity and sound absorption to maximum ease of use and aesthetics.

Owners of apartments and private houses of old construction, at the slightest opportunity, try to replace imperfect wooden structures with modern windows. At first glance, there are no problems with this, in any region there are many large and small firms working in this field. But can everyone be trusted, and are the windows offered for purchase equivalent? Alas, in this segment of the construction business there are many "pitfalls", and the external similarity of the windows does not at all indicate their identical quality and operational characteristics. Therefore, before making a final decision and signing an installation contract, it is necessary to clearly understand how to choose PVC windows so as not to be disappointed in them after a few months.

Such windows entered the everyday life of Russians relatively recently. But even during these 15 ÷ 20 years, like, probably, any outlandish novelty, they managed to “grow” with a whole bunch of mythological rumors, both immoderately extolling their qualities and unfairly attributing non-existent vices to them. First, let's try to clarify this issue.

What they say about PVC windows, and is it really so

• There is widespread the opinion that the installation of plastic windows with double-glazed windows completely solves the issue of thermal insulation - they completely block the path to the cold.

Alas, not everything is so rosy. Create a completely thermal light-transmitting construction is very difficult, although high-quality double-glazed windows and a reliable sealing system can significantly increase the thermal resistance of a window. However, any window construction is also assembly seams, which always serve as “cold bridges” to some extent.

What can be said with confidence in this matter is that the level of room insulation with the installation of high-quality plastic windows will increase significantly.

• The next “myth” is that air is completely pumped out of the space between the glasses, a vacuum is created there.

This statement is not true. In fact, the air is partially pumped out, creating an area of ​​low pressure inside. This is necessary for better sealing - external atmospheric pressure presses the glass as tightly as possible to the seals. It also gives the effect of increasing heat and soundproof qualities. By the way, for the same purposes, some manufacturers use the practice of pumping inert gases into this space, which creates a special, “layered” atmosphere inside the double-glazed window, which effectively dampens sound waves.

• How to treat the statement that the installation of double-glazed windows gives absolute suppression of noise from the street?

You can't believe it completely either. To a greater extent, the design of PVC windows “cuts off” high frequencies, but low-frequency noises, which propagate, including through vibration, alas, find their way. So, if construction equipment is working outside the window, or a busy highway passes nearby, then noise cannot be avoided.

Manufacturers are constantly working to improve the design, but have not yet been able to completely solve this problem.

• The closed PVC window gives complete tightness of the room.

This is another persistent misconception. With a high-quality multi-level sealing system, we can talk about the impermeability of the window for drafts, for exit warm air from the apartment, but it's still far not tightness.

• Another erroneous opinion - the wider the glass is placed on the double-glazed window, the better the window.

The distance between the panes is not a value taken “from the ceiling”. There is a complex system of thermal calculations, which gives rather paradoxical results - an excessive increase in this distance leads to a sharp decrease in thermal insulation qualities. In the production of windows, they adhere to optimal values, proven by theory and practice: for single-chamber double-glazed windows, the maximum thickness should be 24 mm, and for two-chamber - 44 mm.

• The principle is far from always justified that when choosing a window it is not necessary to be limited in the thickness of the profile and the number of air chambers in it: "The thicker the profile, the better the window is, of course."

To argue in this way is tantamount to assert something that a large sledgehammer is much better and more useful than a conventional hammer, because each of these tools has his own purpose. Of course, the number and dimensions of the air chambers of the window profile directly affect the thermal conductivity and sound insulation. But everything should be reasonable and in due measure. An increase in the number of cameras is, inevitably, an increase in the dimensions and weight of the entire window structure, difficulties with its delivery and installation, and a rapid increase in prices. There will be no point in paying extra money for a “super-sophisticated” design, if, according to the climatic conditions of the region, the purpose of the room in which it is planned to install windows, and its location, it is enough to limit itself to no less high-quality execution, but more “budget” option.

• You can often hear that plastic windows violate the normal ecological balance in an apartment.

Well, firstly, polyvinyl chloride , although and synthetic material, but it is absolutely safe for human and animal health. Suffice it to recall that it is actively used for the manufacture of medical containers and devices, food utensils, water vessels, etc. And secondly, if you look around even with a cursory glance around you, you will definitely see polymer products, from household appliances to furniture. But they “sin” for some reason, only on PVC windows.

• Statements about the increased fire hazard of such windows are untenable.

Yes, of course, PVC is a combustible material, but its thermal decomposition temperature is much higher than that of wood - wooden windows will light up faster. Moreover, if there is no open flame, then PVC is more likely to melt than go into fire. As for the substances released during combustion, they are certainly toxic, but carbon monoxide released during the combustion of wood is no less dangerous.

• The service life of PVC windows is short - another widespread delusion.

It all depends on the quality of the profiles, double-glazed windows, fittings used for their production, on the professionalism of the assemblers and installers. Agree that an ordinary wooden window, made by a "crooked" carpenter, even from selected materials, will not last long.

If a really high-quality PVC window was chosen, it should be guaranteed for more than a dozen years without losing any performance characteristics. Of course, the owners must follow the rules for its use and regular maintenance.

• You can meet the opinion that plastic windows impoverish the design with their standardized appearance, they can spoil the exterior design of the house or the interior of the premises.

This assertion does not stand up to scrutiny. People who have never been interested in the existing variety of PVC can say so. In reality, you can order a design of the most bizarre forms, with one-sided or two-sided plastic lamination, which will give the window the desired color or an interesting external texture - under precious woods, under metal, etc. In a word, there are more than enough opportunities to fit a window into the intended design.

Options for choosing PVC windows

First of all, for those who do not know this, the general scheme of the plastic window device:

It would seem that everything is simple and obvious, but almost any element of this design requires special attention.

The figure below shows schematically the main criteria for choosing a PVC window model.

Now about each of these parameters - in more detail.

Type and quality of the profile

The very first and closest attention is paid to the design and quality of the profile - all the operational characteristics of the window and its durability depend on it.

• The material of manufacture - it must be high-quality polyvinyl chloride, durable and absolutely inert to any atmospheric influences. The thickness of the outer walls of the profile is at least 3 mm. Some manufacturers practice, in order to reduce the cost of production, the manufacture of profiles with a wall thickness of, for example, 2.7 mm. It would seem insignificant, but the rigidity and wear resistance at the same time deteriorate sharply, and there is no need to talk about the long service life of such windows.

For regions with severe winters, you should choose a profile made of PVC with increased frost resistance. Usually this is indicated by the additional index "M" on the label.

• The number of air chambers - the thermal insulation characteristics of the window largely depend on this parameter.

The number of chambers is calculated according to the width of the profile. If there are horizontal jumpers dividing the cavity into several vertical compartments, then these are not considered additional chambers. The minimum number of cameras allowed by the standards is two, but, as a rule, there are no such products due to their lack of demand. Typically used for residential installations t pex - or five-chamber profiles.

Three-chamber profiles, with a total thickness of about 58 ÷ 60 mm, are certainly much cheaper. It makes sense to buy them if the climate of the region is not characterized by harsh winters, or if the window will be installed, for example, for glazing a loggia or balcony. They are acceptable in the kitchen or on the south side of the building, provided that the house has efficient heating and general thermal insulation.

For the main part of Russia, where January frosts below -20 degrees are considered commonplace, it is better to purchase a high-quality five-chamber profile with a total thickness of over 70 mm - its resistance to heat loss is much higher. True, you will have to pay more for this.

There are other varieties - with four or six chambers, but they are rare and, as a rule, have a specific purpose.

• The presence and type of reinforcing insert. According to existing standards, all profiles longer than 800 mm or having a coating other than white must necessarily have a reinforcing insert. However, leading manufacturers equip all their products with such a structural element. This reinforcement will create the necessary rigidity and stability of the window structure, prevent deformations associated with thermal expansion, which will significantly increase the service life.

As a reinforcing insert, a profile of corrosion resistant galvanized steel with a thickness of about 1.2 - 2 mm. If a thin material is used, for example, 0.5 mm, or if it does not have anti-corrosion protection, then this can be considered a fiction - neither rigidity nor durability can be expected from such a window, and the insert is made only to “blur” the eyes.

The reinforcing insert may have a closed or open profile. Of course, with its closed form, the strength characteristics are much higher. However, this affects the total mass of the window structure and, of course, its cost. It is possible, for small windows, to confine oneself to a profile with high-quality U-shaped reinforcement, however, if the means and installation conditions allow, it is still better to give preference to closed ones.

But if pseudo-reinforcement made of two flat metal inserts placed closer to the edges of the profile, then it is better to refuse this option right away - there will be no resistance to deformation, for example, to bending or twisting.

• The “appearance” of the profile is also of considerable importance. The usual technology for decorating windows is the use of special laminating films, which can be selected from the proposed catalog. At the same time, it is possible to perform one-sided or two-sided lamination, and the outer and inner surfaces can be finished with different textures. .

The design of the shown profiles is the same, the decoration is different

There are profiles dyed in mass at the production stage, when pigment compositions are introduced into the initial mass. Profiles with acrylic coatings applied by co-extrusion are of good quality - an additional protective and decorative layer is obtained, which at the same time becomes inseparable from the PVC base component. Another exterior finishing technology is the application of colored acrylic lacquer to a white surface.

• When choosing, the manufacturer of the profiles is very important. It hardly makes sense to contact an unknown or already notorious manufacturer - you can find a lot of examples when such windows disappointed their owners already in the first year of operation. If you have already decided to go for a replacement, then it is better to give your savings for really high-quality products, which are accompanied by manufacturer's warranties.

You can safely purchase REHAU, KBE, VEKA + profiles. Quite trustworthy LG-Chem, MONTBLANC. In the category of premium windows, DIMEX and THYSSEN are traditionally the leaders. Several domestic companies have emerged trying to keep up with foreign manufacturers in terms of quality, for example, SOK (Samara window structures), DI FENCE or PROPLEX. It will never be superfluous to go to the official website of the manufacturer and get acquainted with the features of the product - the raw materials used, the technology, the variety of models provided by the guarantees. Well, when ordering, you should not hesitate to demand documents confirming that the profiles are really a brand, and not a cheap fake.

Choosing a double-glazed window

The area of ​​the glazed area of ​​the window is always many times greater than the space occupied by the plastic profile, so the value of the quality of the double-glazed window cannot be overestimated.

The design of double-glazed windows is, in principle, the same for all models:

1 - glass, at least 4 mm thick.

2 - air chambers formed between the glasses.

3 - distance frames that provide the same distance between the glasses.

4 - drying backfill (silica gel or other material with increased hygroscopicity). The main goal is to maintain optimal humidity conditions in the chambers.

5 - sealing adhesive composition, collecting all the elements into a common structure.

What are the main criteria for choosing a double-glazed window:

• Thickness and quality of glass. Most models use 4 mm thick glass. In the event that the windows face the street with an increased noise level, it makes sense to consider installing external glass with a thickness of 5 or 6 mm. This will significantly increase the soundproofing qualities, since glasses of different thicknesses will never resonate.

Glass must be tempered, having undergone special heat treatment after cutting it into the desired size. At the same time, tempered glass in no way loses its light-transmitting abilities and any other qualities. But on the other hand, firstly, it significantly, by 5 ÷ 6, increases its strength characteristics, resistance to both shocks and bending or compression loads. Secondly, even if accidentally broken, it will crumble into small fragments of almost regular shape without sharp cutting edges.

An even safer option is laminated glass - triplex. They can withstand even a directed blow, resist a burglary attempt, and in case of destruction they do not shatter into fragments. In addition, such glasses are much less susceptible to microvibrations, which means that they dampen sound vibrations more effectively. True, the price of such double-glazed windows is quite high.

There are glasses with internal metal reinforcement. Recently, there has been a growing trend in the popularity of glasses with electromagnetic protection. It can be a metal mesh or conductive film, which are connected to the ground loop. This measure helps to prevent the impact of external electromagnetic radiation, to prevent leakage of information transmitted over radio frequencies.

• The number of chambers and their width.

Double-glazed windows are single- and double-chamber. A single-chamber version is two glasses separated by a certain distance. The total thickness of such a package is in the range from 24 to 30 mm. Usually I choose such a design according to the same principle as the number of cameras in the profile - for the southern regions or for unheated premises.

Two-chamber, respectively, have three glasses and two air or gas layers between them. The thickness of such packages is usually from 32 to 44 mm. Thermal insulation and noise canceling the quality in this option is certainly much higher, so for living quarters it is best to choose it.

Find out and also review the causes and solutions in our new article.

In a two-chamber double-glazed window, various glass layout options are possible. So, they can be of the same thickness and installed at the same distance from each other. To provide increased sound insulation, if necessary, it is better to choose a different scheme - the cameras have different widths (spacers are used, for example, 6 and 16 mm), and the outer glasses are thickened. When passing through such a "pie", sound vibrations are damped most effectively.

• Special energy-saving technologies in the design of double-glazed windows.

In order to significantly improve the thermal performance of double-glazed windows, reduce the cost of heating in winter and air conditioning in summer, special technologies have been developed. First of all, this concerns the application of a film coating on glass or low emission sputtering based on silver ions. Depending on the technology used, there are k-glass i - glasses. The first ones are much easier to manufacture and, accordingly, cheaper. The latter have more impressive energy-saving characteristics, but their production is more difficult, which, of course, is reflected in the price.

Such coatings in winter reflect the heat flow back into the room, preventing it from cooling out through a large window area. At the same time, they prevent the free passage of hard solar radiation into the apartment in the summer, keeping it as cool as possible.

The marking of such double-glazed windows is usually given by a formula indicating the thickness of the glasses, the type of coating (if applied) and the distance between them. For example, the designation "4i-10- 4 – 10 – 4 i" says that this is a two-chamber double-glazed window, with a glass thickness of 4 mm, a distance between them of 10 mm, and the outer and inner glass, in addition, belong to the i-type.

Even more effective in terms of heat preservation are double-glazed windows that do not have rarefied air, but the injected inert gas (usually argon or krypton). The special molecular structure of these gases significantly reduces the coefficient of thermal conductivity. For example, in comparison with the usual one (with the same other characteristics), a double-glazed window with argon gives a significant increase of 5% to energy saving. And if a combined scheme is used, then this figure is even higher: on a double-glazed window "4 - 16Argon-4i" we can talk about an increase of 10 ÷ 12%. Even more impressive will be the results on double-glazed combined double-glazed windows.

There are glasses with a special sun protection layer, which is especially important in summer for rooms oriented to the south or southwest, especially in regions with a hot climate. True, such glasses usually have reduced and light-transmitting ability.

Scheme of the window and a set of fittings

When the buyer has to decide how he sees it and according to what scheme it should work. Basic principles works are shown in the figure:

The main schemes of the "work" of the window

Schemes can be used both individually and in a certain combination, for example, rotary opening plus folding for ventilation.

You should consider the number, shape and size of all glazed areas. Many owners are often tempted to have one large glazed sheet for the entire opening area. However, it must be taken into account that this is a very heavy load. on fasteners. In addition, the larger the window area, the greater the likelihood of resonant transmission of sound waves, and therefore - lower soundproof quality. It is more expedient to distribute a large area into several sections, separated by imposts.

The correct and easy operation of a window directly depends on the quality of the fittings used in it, and the issue of its choice is of paramount importance. In no case should you purchase products with plastic elements - they do not stand up to criticism, they never have certification and will last for a very short time.

Fittings must be exclusively steel (preferably alloy steel), so that it can withstand several dozen daily cycles of work over the years. At the same time, it must be perfectly fitted, so that any member of the family can easily open or close the window.

The quality of fittings is the key to reliable and long-term operation of the window system

When choosing, you should pay attention to reinforced fittings with anti-burglary characteristics. It has several degrees of security, and the most reliable one can withstand even the impact of a powerful power tool.

If there are young children in the apartment, you should take an interest in locking systems so that the child cannot open the window on his own. These can be removable handles with plugged sockets for them, special hidden push-button latches, swivel function limiters, mortise or overhead locks, etc.

One of the types of "children's" locks - the child will not be able to open the window at a dangerous distance

There are also additional fittings, which, for example, provide a stepwise opening of the window, prevent its arbitrary slamming in a draft, prevent improper closing of handles, etc. The fittings also include all handles, decorative overlays and other items of external decor.

Self-respecting companies involved in the production and installation of plastic windows usually use high-quality fittings from leading European manufacturers. The undisputed leaders in this market segment are MACO, ROTO or SIEGENIA-AUBI.

Seals

Another important criterion for choosing PVC windows. A lot depends on this “frontier” - the maximum possible tightness of the closure, thermal and sound insulation, protection of the fittings from dust and dirt getting into it, which can cause its abrasive wear.

In window systems, one or more (up to three) sealing circuits can be used. Depending on the location, they are external, internal or intermediate. In addition to sealing the moving part, the sealing elements must be located on both sides of the installed double-glazed window.

Seals can have a different cross-sectional profile. They are made of rubber, silicone, special rubber or composite polymer compounds. Each of them has its own advantages and disadvantages, both in terms of reaction to low temperatures, and in terms of resistance to abrasion and deformation loads, cracking, delamination, etc. It is believed that the EPDM composite composition (translated into Russian having the complex name “ ethylene-propylene-thermopolymer-rubber"or EPTK).

How to choose a window installer company

No less, and perhaps even decisive, is the choice of a company that should assemble and install windows. There are a lot of offers for such services, and it is important not to fall for the hook of unscrupulous performers or even amateurs in this matter.

The quality of a window is not only proven materials, but also the professionalism of the craftsmen of the company involved in its assembly and installation.

You should never "buy" at clearly underpriced prices - most often they are offered by one-day firms, and there will be no one to present claims for quality in a year. It should definitely alert if this organization, for example, does not have an office, and all negotiations are conducted only by mobile phone. In this case, as a rule, the contract is proposed to be concluded at the customer's home.

If, during a telephone conversation, you are asked to measure the window opening yourself to place an order, hang up immediately, without getting involved in any discussion, as there is not even a smell of professionalism here.

A reputable company must demonstrate samples of the profiles and double-glazed windows it uses in its office - usually split window models are installed for this. Even a list of questions that a competent manager will ask can say a lot. In order for the window to turn out to be of really high quality and to fully perform its functions, the manufacturer must evaluate a lot of information:

• The series of the house, the material of the walls - most likely, the installers have already had to deal with similar apartments and they have developed the best options.
• Customer's wishes for window configuration. Not all the "whims" of the owner of the apartment can be implemented, and the manager's task is to find a compromise solution, both in terms of "deglazing" and in terms of the operation of the valves.
• Be sure to take into account the direction of the windows to the cardinal points, the location of noisy driveways or vice versa, quiet courtyards. This will make it possible to more accurately determine the number of profile chambers and the type of double-glazed window.
• As a rule, issues on the installation of ebbs and window sills are solved at the same time, sometimes it is immediately planned from PVC. Almost certainly, the installation of a mosquito net, a regular consignment note or a roller shutter type will be offered.
• A serious company will always meet a good customer and make him a significant discount if several windows are purchased and installed at once.
• It is possible that the list of company services also includes innovative solutions, for example, a ventilation system built into the profile.

Only modern, but experienced enterprises can satisfy the listed requirements. One of the leaders in the niche under consideration is the company "Window Factory". Its competitiveness is determined by many clear advantages:

• the presence of own production, which allows maintaining acceptable prices for the company's product and services for customers;
• experience in the field of 14 years;
• warranty customer support for 5 years after the completion of the order;
• friendly customer service system.

In addition to being customer-oriented, the company has strengthened its position as a leader through the production of innovative products, bringing to life completely new, "attentive" windows to the requirements of the customer.

The first technology installed free of charge on products from the "Window Factory" is called SmartBox III. It is represented by a supply valve responsible for climate control, located in the upper part of the window. The valve consists of:

• special curtain, selected according to the wind load;
• adjustable position switch.

Using SmartBoxIII technology, even with the windows closed, you can enjoy fresh air, while:

• without releasing room heat;
• while maintaining sound insulation at the original level.

The appearance of the structure when installing the valves is not violated.

The second innovative product of the Window Factory is heat-saving windows.

The thermal effect of the structures is achieved by applying a special pollination to the glass, which, while remaining invisible to the eye, makes significant changes in your life:

• keeping heat 40% more efficient than multifunctional glass and 97% more intense than ordinary double-glazed windows;
• in summer, it reduces the degree of penetration of natural heat from the street, keeping the room cool, while letting in 30% more light;
• in winter, it retains heat inside the apartment, keeping a comfortable temperature on the windowsill, on average + 6 ° C higher than that for a standard double-glazed window;
• reduces the risk of condensation from temperature differences;
• saves money spent on heating without releasing heat, which is especially important for private residential buildings.

If desired, the thermal package can be supplemented with tinting to create a cozy and private atmosphere. For safety-conscious clients, the Window Factory offers the possibility of installing tempered glass.

The PVC profile of double-glazed windows from the "Window Factory" is represented by individual REHAU designs that have passed all stages of quality control. The fittings of the products are represented by the Titan AF line, which provides the following advantages:

• prevents rapid wear of structures;
• provides anti-burglary resistance;
• enhances sound insulation;
• allows you to choose the intensity of ventilation.

By choosing the innovative offers of the Window Factory, you maximize the efficiency of the installed double-glazed window, creating the most comfortable atmosphere at home.

A lot can tell and the impression of the visit of the measurer. It's not even about his appearance and demeanor (although this sometimes creates a certain opinion). If the master limited himself to two or three measurements and spent no more than five minutes on this, most likely, you should refrain from further contacts. A professional approach involves an assessment of at least 10 ÷ 12 parameters, and usually takes even up to half an hour. In no case should you pay money for taking measurements - this service is not paid and, again, does not oblige the customer to anything yet.

Only when a detailed project is drawn up in the company's office that completely suits the client, with all the drawings and diagrams, a list of materials and an estimate for assembly and installation, you can sign a contract. At the same time, it is imperative to stipulate the maximum allowable terms for the completion of all work, the responsibility of the parties for failure to fulfill obligations, and a number of other important points.

So, you should pay special attention to whether the delivery of windows, lifting them to the floor, dismantling old frames, garbage disposal, and the use of consumables (for example, mounting foam) are included in the estimate payable. Often, inexperienced customers fall into such "traps" of unscrupulous firms, who then, during the installation of the window, face the need for additional costs not specified in the concluded agreement.

And, finally, another video with tips on choosing PVC windows.

Video: how to choose the right plastic window

Plastic windows firmly occupy a leading position. They are distinguished by a high level of heat and sound insulation, in addition, they provide the opportunity to choose fittings, the method of opening the window and the color of the profile. You can also choose a double-glazed window with the required number of cameras. But few people think that it is the window profile that ensures the strength and durability of the entire structure. In the article, we compare plastic window profiles of 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 separated by bridges that create several air chambers. A special technical calculation determines their size and location. The wider the profile, the greater the number of chambers in it that increase the heat-preserving 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 one or two chamber types, the width of the glass in a standard double-glazed window is 4 mm (M1 brand).

Each cavity has its own purpose:

• for the outflow of water;
• fastening accessories;
• responsible for strength, etc.

The color of the profile can be varied, the color is applied in several ways:

• co-extrusion method - multilayer films create a kind of barrier that allows the product to withstand dynamic loads without damage;

• lamination - with texture imitation, for example, marble or wood;
• monochromatic coloring.

Characteristics of PVC profile for plastic windows

Material

• This product is made of 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.

• Polyvinyl chloride, due to its distinctive properties, makes it possible to manufacture frames for double-glazed windows not only in a rectangular or square shape, but also in the form of arches, triangles, circles, and so on. Thus, giving absolutely any simple or complex configuration to the window, allowing you to translate into reality even the most non-standard idea of ​​designers and architects.

Design

The inner part of the plastic body of the profile is divided by longitudinal partitions, which in turn form cavities (air chambers). The minimum number of chambers in the 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 figures. It should be noted right away that 3- and 5-chamber profiles are popular.

Reinforcement

To give rigidity, the profile is additionally reinforced. The metal frame 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 under 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 the metal reinforces 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 a balcony, a profile with closed reinforcement is required.

Profile class

The wall thickness of the profile determines its belonging to a certain class:

• Class A - profile wall thickness 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 plastic window profile manufacturers

Many domestic and foreign manufacturers present their products on the Russian market. The leading positions in the rating of profiles for plastic windows are occupied by companies:

• Germany - REHAU, VEKA, KBE, SALAMANDER, SCHUCO, KOMMERLING;

It is believed that the German profiles of plastic windows are superior to the products of other manufacturers in terms of quality, color whiteness, and technical characteristics. They do not lose their properties even during a long service life, perfectly withstand almost any dynamic load and significant temperature changes (from -50°С to +50°С).

The KBE company manufactures and supplies 2 types of the most popular profiles: KBE Etalon and KBE Expert.

KBE Etalon - three-chamber profile

• The mounting width is 58 mm;
• the width of the front walls - 3 mm;
• the thickness of the double-glazed window can be up to 34 mm;
• 3 cameras 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 ensure resistance to heat transfer. Such windows have a high degree of tightness, which exceeds the existing requirements of GOST by 5 (!) times, which guarantees the complete absence of dust and drafts in the room;
• two sealed 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 the window is closed;
• stiffening ribs are installed in the KBE profile, which provide additional strength to the window structure. Also, special stops allow to increase the rigidity, with the help of which the exact location of the reinforcing metal insert is achieved.

KBE Expert - five-chamber profile

• Mounting width is 70 mm;
• the width of the front walls - 3 mm;
• the thickness of the double-glazed window is up to 42 mm;
• 5 cameras in the frame and sashes, 3 or 4 in the impost (horizontal and vertical window bars);
• Suitable for use in harsh environments (-60°C);
• sealing contours correspond to class A;
• service life - 40 years;
• in the manufacture of environmentally friendly materials are used, does not contain lead.

Advantages:

• a five-chamber structure allows you to achieve a better thermal insulation value, such a profile is able to retain heat 20% more than typical three-chamber systems. You can achieve excellent sound insulation by installing wide double-glazed windows in a 70 mm profile;
• 13 mm profile groove allows you to install anti-burglary fittings, thereby ensuring the safety of the room;
• the KBE Expert profile has additional horizontal bridges, thanks to which the handles and hinges will be securely fastened;
• when installed, the mounting seam is wider by about 20%, in turn allowing for additional insulation.

Estimated cost of windows from KBE profile

An important factor when choosing one or another double-glazed window is its price. Often it is decisive, but high quality German window profiles cannot be cheap. Below is the approximate market value in Russia.

• On average, a single-chamber double-leaf window with dimensions of 140x130 cm, in which one sash is of a deaf type, and the other is a tilt-and-turn one, will cost:
  • from a profile of 58 mm from 7500 rubles,
  • from 70 mm - from 10,000 rubles.

• The price of a two-chamber three-leaf window with a size of 140x203 cm, in which the first sash is rotary, the central one is of a deaf type, and the third one is tilt-and-turn will be from:
  • from 58 mm profile 13,000 rubles;
  • from 70 mm 14500 rub. and higher.

• When buying 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 profile of 58 mm 11,000 rubles;
  • from 70 mm from 13000 rub.

What to look for when choosing a plastic profile with a double-glazed window

In order to determine what profile thickness is needed, one should have basic knowledge about a double-glazed window, because up to 70% of heat losses occur through it.

This transparent element consists of 2 or more glasses that are hermetically connected to the frame. Between them, a chamber (air gap) is formed, filled with rarefied air or an 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 an air gap of 16 mm, abbreviated as 4-16-4. Thus, its mounting width is 24 mm. A 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.

Therefore, an appropriate profile is selected for the required double-glazed window. For example, the optimal solution for an ordinary apartment or house is a 5-chamber profile with a 70 mm installation width and a 30 mm double-glazed window, where a heat-reflecting coating should be applied to one glass.

Making a window with a plastic profile is convenient, beautiful and practical. But the window is not only a complementary detail of the interior ensemble. Given its size in the room, technical characteristics are of great importance, especially with the increased parameters so popular today. Therefore, the choice of a plastic window company is very important in the process of selecting a suitable design.

Looking through the rating of plastic windows companies, keep in mind that not only the position of the company is important, although it implies a certain quality guarantee. Pay close attention to the technical indicators of the profile and fittings specified by the manufacturer.

According to the standards, the profile is formed by at least 2 chambers with air space inside. Depending on the requirements for the level of the protective mechanism against extraneous sounds and the preservation of heat, their number varies up to 6 parts. Each of the departments must bear its own load.

The fittings must ensure uninterrupted operation when opening and closing, adjust the set position, excluding jamming in the wrong setting.

Window Functions

Please note that the functionality of a window is a set of performance characteristics, and not individual points. Regardless of the type of construction and the manufacturer of plastic windows, the selected product must meet the following requirements:

What brand of plastic windows is better?

When choosing a manufacturer, keep in mind that the highest prices are not necessarily indicative of the same performance. But you should not be seduced by cheapness and high-profile offers of free services either.

Quality designs require the appropriate configuration of parts. That is, taking into account the cost of individual window elements of good quality, manufacturers of many well-known brands simply cannot lower the price bar. Therefore, too low a price rather indicates either a lack of professional skills of workers, or low-grade components. In both cases, the duration of operation and usability will not meet expectations.

Be sure to check out the company reviews. Note for yourself how satisfied customers are some time after installation:

• how often do breakdowns occur
• what parts fail
• how competently and quickly troubleshoot the company's employees.

Important! To obtain such information, use not only the Internet, but also the responses of friends (it is their opinion that is usually truthful and preferable).

The main criteria for choosing a brand

Consider the offers of the plastic windows market, focusing on several criteria that are really important for the subsequent period of operation or affect the warranty coverage. Pay attention to the working conditions and the services provided by the company for plastic windows, set out in the list below:

Companies at a Glance

• representatives of the German tradition - Veka, Rehau, Salamander, Trocal, Funke
• well-established domestic corporations - Montblank, Proplex, Plafen, Krauss

Good afternoon! Every person in life is faced with the question of choosing a high-quality plastic window. If you are faced with such a problem, I suggest reading this article.

My many years of experience in working with plastic windows gave me a lot of knowledge, which I will gladly share with you.

The plastic window is made of a multi-chamber system, which not only retains heat, but also protects the house from moisture, dust, wind and noise. For the choice of high-quality windows, the manufacturer plays an important role in the first place. It is better to choose a window manufacturer based on the reviews of customers, friends who installed windows. The most popular manufacturers: Rehau, KBE, Veka, Salamander, Proplex.

An important role is also played by the material from which the profile, double-glazed windows and fittings are made.

Reviews and advice from our customers on how to choose the highest quality and best plastic windows

If you decide to install windows, then you first need to decide which plastic windows to choose. It is important to know what to pay special attention to in order to avoid many problems. We give below reviews of plastic windows that our customers leave. Perhaps they will help you figure out the question - how to choose plastic windows.

Anatoly, 45 years old, Moscow:

Pay attention to the type of profile you are using. The profile can be imported or domestic. Many experts argue that imported ones are of better quality - and this is true. Sometimes, in order to make an inexpensive profile, they use secondary raw materials. Therefore, be sure to check this point with consultants. Carefully study the cut that is shown to you as an example - its thickness should be 1.5 mm, it should be made of galvanized steel. Only such a profile will be reliable and of high quality.

Try to carefully consider the attached accessories. High-quality - this is German-made accessories. The simplicity and convenience of managing your plastic window depends on it.

The number of air chambers inside the window must be at least three.

A company manufacturing plastic windows must have samples of work and sections of profiles. Production and installation must be certified. Never hesitate to ask for supporting documents and samples. This will save you a lot of worries later.

Proper plastic windows will serve you reliably. I want to note that only professionals work in the company "Repair" of windows. You can trust them with your home without hesitation!”

Stanislav, 37 years old, Moscow region:

“... I would like to advise all those who wish to purchase the best plastic windows to pay attention to the quality of double-glazed windows.
High-quality double-glazed windows should be:
Not less than 32 mm thick;
There must be at least two air chambers in a double-glazed window;
Must have a heat reflective coating;
The brand of glass must be M1-polished;
When I needed to change the window in the kitchen in my apartment, I contacted the Window Repair Company. Double-glazed windows turned out to be of really high quality - any wind and frost are not terrible with them. Guys, thank you!

When choosing which windows to buy for your home or office, each of you is looking for the best solution to keep warm and cozy, trying to find the best combination of price and quality. The manufacturer of a high-quality plastic profile recommends paying attention to the following parameters of a PVC window:

Profile

There are several grades of profile quality, determined by the thickness of the outer wall. A thinner profile may cost less, but it cannot always ensure the preservation of the window's consumer properties - heat and sound insulation, geometric stability, and durability. The best firms work with a class A profile, which allows you to guarantee quality.

Fittings and accessories

Windows of good quality should open and close without problems at any time of the year, protected from dust and street sounds. Cheap seals, handles, swivel fittings and fasteners not only reduce the cost of the window, but also reduce its quality. After all, with bad components, even a first-class profile will not save.

Glass

Pay attention to what glass the manufacturer uses. Good windows have double-glazed windows made of polished glass, often with a sun protection coating. Cheap Chinese glass can later upset you with cloudy stains, scratches and even cracks in severe frosts.

Mounting

Whatever the best plastic windows are, improper installation will cross everything out. We advise you to use window installation services offered by the manufacturers themselves. Hiring outsiders to install or installing it yourself will void your warranty.

Price

The final cost of the installation window depends on all the previous points. You can find and install a window cheaper, but the total savings can be a maximum of 20%, and the life of the window will be unpredictable. Just find out how much maintenance and repairs cost, and consider whether it is worth installing windows that may need to be repaired.

From the experience of cooperation with window manufacturers, we confirm that the most common problems in window operation are caused by low-quality fittings and improper installation. It is better to spend a little more money and install the highest quality window than to regret the money spent and prepare for repairs again.

The rating of plastic windows is one of those criteria by which it would be quite easy to determine the best plastic windows. However, you will not find such an objective and comprehensive rating. This is due to a number of reasons.

Firstly, the rating of plastic windows cannot be objective, since the assessment will always be based on a subjective judgment. Expert or popular opinion is always only the opinion of subjects based on some criteria, the set of which is very different.

Secondly, the rating of windows cannot give a comprehensive assessment, because window products are a technically complex product with versatile and multifaceted characteristics. It is not at all necessary that the best window should be made of the thickest (widest) profile, and the warmest double-glazed window is not always necessary for glazing.

Thirdly, the rating of plastic window brands cannot guarantee the quality of PVC windows in operation. Even the best rating windows can be damaged by poor installation or perform their functions improperly due to manufacturing defects.

Which plastic windows are better: Veka, Rehau, KBE?

As in any matter: the fish is looking for where it is deeper, and the person, where is better. In this regard, it is always more interesting for an ordinary consumer to buy a higher quality product at a bargain price. Therefore, having an idea of ​​which product from the presented line has the best characteristics, it is always easier to find it at the best price.

Choosing windows popular today based on Rehau, Veka, KBE, etc. profiles, a person makes a conscious choice in favor of a well-known and reliable brand. However, windows based on the technically best profile have excellent potential, but do not guarantee superior performance.

Indeed, in addition to the profile itself, the window contains fittings, a double-glazed window, the quality of work of the window manufacturing company and the installers of the installer company. Thus, a window from a Rehau brand profile will not necessarily be better than KBE or Veka windows.

Why is there still no better window company and no better plastic window?

This question torments both buyers and sellers of windows, journalists of popular magazines and editors. Increasingly, the question of choosing the best PVC windows is being asked in construction forums and search engines. But the answer, unambiguously fair and correct, has not been found. Why?

One of the reasons is the complexity of the design itself, as we described earlier, which consists of a large number of elements. It can be used as expensive and high quality components, as well as less expensive, less reliable.

Add to this the human factor, which is present in any assembly and manufacturing process using the labor force of a living person. You will get a black box with a large number of unknowns at the input and a product with mysterious properties at the output.

Another component that also comes into play when determining the quality of an installed window is the installation process. It is not difficult to imagine a situation when an excellently made window in everything will be irrevocably spoiled by a clumsy installer.

Note!

It was complaints about such an installation that one had to hear in the process of "sanation" of residential buildings. The installation of plastic windows was entrusted to non-professionals, and, as a result, windows that were initially good in quality turned into a non-functional and low-quality element of the window opening as a result.

If, nevertheless, to determine the best window, then for this you need to compare and select products according to the following rules or in one of the following ways: by price, by quality, by the optimal price-quality ratio.

The methodology for an independent rating of plastic windows, which gives an assessment that is interesting to the buyer, as it seems, should be based on absolute values ​​that are directly related to the window structure. The quality of services (delivery, installation) can already be assessed in relation not to a window, but to a specific window company.

Summary:

• The rating should include goods - plastic windows and PVC doors - of the same "weight" category. Possessing similar, if not the same technical characteristics. Windows of different segments should be compared in their subgroups.
• The rating should evaluate the same parameters according to a predetermined list - the most significant characteristics from the point of view of the window consumer.
• The rating should be compiled by an independent group of experts or formed by public opinion - a representative sample from the totality of all possible window consumers.

Only by working in this way, the results obtained will have at least some meaning, and the rating of plastic windows itself will be in demand, useful and relevant when choosing windows and buying them.

What plastic windows are better to put?

At first glance, the design of plastic windows is very simple - glass, frame, handles. However, windows from different manufacturers differ from each other both in quality and in price. When choosing windows of a well-known brand, the buyer pays not for a big name, but for reliability and durability. Let us consider in more detail all the elements that make up the windows, and find out which plastic windows are better.

What plastic windows are better to put in an apartment or house? Good plastic windows do not just close the window opening - they perform many functions.

The main one in our latitudes, of course, is heat conservation. Owners of low-quality windows are well aware of the problem they can become in winter. Cold and drafts are inevitable for those who decide to save money and put the cheapest artisanal model.

But the best plastic windows provide perfect thermal insulation - for example, when it is -5 o C outside, the temperature near the inner glass never drops below +20 o C. In summer, windows can protect the apartment from heat and too bright sun - for south-facing rooms, you can choose windows with tinted double-glazed windows and infrared protection.

An important function of plastic windows is sound insulation, this is especially true for those who live near a busy road. Sound insulation depends on the thickness of the glass and the distance between them.
Windows also protect the house from illegal entry.

Helpful advice!

Well-known manufacturers are constantly improving the burglary resistance of windows, and many models are not at all easy to open from the outside. And, of course, do not forget about such trifles as protection from insects with a mosquito net and from light with the help of blinds.

There are many companies producing plastic windows - about 10-15 largest manufacturers (KBE, Rehau, Veka, Salamander, Schuko, Kommerling, Proplex, Deceuninck, Montblanc, LG Chem and others) and several dozen smaller ones. Each company offers a number of window lines - from affordable to luxury options.

It is not easy to sort out such a number of proposals, it is even more difficult to say which plastic window companies are better. When choosing a window, you should not start from the brand or, moreover, the price, but from your own needs. Here's what to look for when choosing a window:

Material and profile uniformity

Usually the profile for plastic windows is made of metal-reinforced PVC. PVC is resistant to deformation, harmless to humans and the environment, is not afraid of temperature changes, moisture, oils, acids and solvents. PVC can be used to make not only standard square and rectangular windows, but also structures of any shape - round and semicircular, triangular, etc.

High-quality PVC of a uniform color, its surface is smooth, without graininess, irregularities and streaks, it is absolutely odorless.

Profile thickness

A profile is a structure with internal partitions. The thickness of the outer and inner walls of the profile is normalized. Depending on it, the profile is assigned to one of three classes - A, B or C.

1. Class A - external walls with a thickness of 2.8 mm, internal - from 2.5 mm. Windows from such a profile provide good heat and noise insulation, they are installed in residential premises.
2. Class B - external walls with a thickness of 2.5 mm, internal - from 2.0 mm. Class B profile windows are recommended for installation in non-residential premises. They are less durable, keep heat worse and do not provide sufficient noise protection.
3. Class C - all other profiles that do not fit the standards A and B. There are no strict requirements for the class C profile.

Obviously, the thicker the profile, the stronger and better it is. Most modern window profiles have an outer wall thickness of 3 mm or more.

Number of air chambers

Inside the profile there are several cavities - air chambers that provide protection from the cold and loud sounds from the street. The minimum number of cameras in a profile is 3, the maximum is 8. The most common are 3 and 5-chamber profiles. 3-chamber is suitable for windows facing a quiet courtyard or south, 5-chamber is better to choose for windows facing the road or oriented to the north.

Double-glazed window is called a block of glasses, hermetically connected to each other. The space between the two panes of glass is the chamber. Many people confuse cameras in a profile and cameras in a double-glazed window, but these are different concepts.

The most common double-glazed window is a double-glazed window, consisting of three glasses and two chambers between them. However, there are also three- and four-chamber double-glazed windows for especially cold climates. Single-chamber packages are only suitable for glazing loggias, balconies or gazebos.

The quality of the glass is no less important than the number of cameras in a double-glazed window. Ordinary glass is the cheapest, but today many people choose glasses with additional properties. For example, glass with a coating that reflects infrared rays - it is as transparent as ordinary glass, but at the same time it retains heat in winter and pleasantly cool in summer.

Note!

There are fire-resistant glasses that do not break even when exposed to extremely high temperatures, and glass laminated with triplex - such a window is almost impossible to break, but even if someone succeeds, there will be no sharp fragments when broken.

Seal quality

Seals are needed to ensure that the window closes tightly, as well as to ensure the tightness of double-glazed windows. Seals are made of rubber, rubber plastic, silicone or natural rubber. The most inexpensive (and short-lived) option is rubber; rubber and silicone seals are installed in more expensive windows. They do not deform even after long use, temperature changes also do not affect their quality.

Profile width

The width of the profile must be at least 50 mm. Most of the best plastic windows are 58-70 mm wide and larger. The thickness mainly depends on the number of glasses - the more there are, the “warmer” and wider the window. In most cases, a width of 58-70 mm is sufficient to provide warmth and silence in the house, wider profiles are in demand in the harsh northern climate or in very noisy areas.

accessories

A plastic window is a rather heavy structure, moreover, it is constantly subjected to loads - windows are opened and closed daily. Therefore, fittings for such windows must be especially reliable. Most often, the owners of cheap low-quality windows complain about the fittings - the handles become loose and fail, or even fall off completely, the window hinges jam and warp.

To avoid such troubles, buy windows from reputable manufacturers who not only strictly control the quality of fittings, but also constantly develop new, more convenient and durable systems. Adjustable fittings are better than unregulated fittings - it allows you to open the window exactly as much as required, and special stoppers will not allow a draft to slam the window.

Anti-burglary systems will not allow intruders to enter the house (this is especially true for apartments on the ground floor, cottages and private houses). Worthy manufacturers of window fittings include Roto, Aubi, Winkhaus, Siegenia.
