Comparison of plastic windows from different manufacturers. Comparison of manufacturers of plastic window profiles Which company is good plastic windows

Plastic windows have long taken a strong place on the market among other glazing systems. Thanks to their excellent technical characteristics, they create the most comfortable conditions for living and working indoors. Today, the best plastic windows are produced in Germany, Austria, Turkey and Russia. Which of them are the standard, and which ones are better to refrain from buying?

Technical characteristics of plastic windows

At first glance, a plastic window seems to be a simple structure consisting of a profile, double-glazed windows and handles. But, in fact, which significantly affect the functionality and specifications window.

A high-quality plastic window should have the following parameters:

  • reliability;
  • durability;
  • high level of heat saving;
  • moisture resistance;
  • soundproofing;
  • draft protection;
  • protection from dust and insects.

The main one is the heat saving indicator.

Owners of apartments with low-quality glazing know for themselves what problems can be in winter. Cold air pierces through cracks, and even heating system in combination with additional heaters, it cannot cope with maintaining normal room temperature.

If you install the best plastic windows in your apartment, then even at an air temperature outside the window of -5 o C, the air near the window sill will not drop below +20 o C. This effect is due to the complex design of the profile, consisting of several air chambers, as well as the presence double glazing.

Soundproofing is a topical issue for apartment owners whose windows overlook a noisy highway, nightlife or other crowded object. Provides draft protection rubber seals installed along the perimeter of the frame, as well as a high-quality three-layer assembly seam. Among other things, plastic windows protect the home from burglars. With each goth, manufacturers improve protection mechanisms, increasing the reliability of both locking devices and the entire profile as a whole. Protect from direct sunlight and infrared radiation will help special films on glass: anti-reflective, tinted, mirror.

plastic profile

Almost all specifications plastic construction profile dependent. Let's consider its main features. Each manufacturer produces a profile according to its own technology. There are: three-chamber, four-chamber, five-chamber and even eight-chamber profile. On the finished window it is impossible to see the number of cameras, so there are samples in the offices by which you can study the window in section. All types of profiles are hollow inside and differ in the number, location and thickness of the partitions. Partitions form chambers that are filled with air. As you know, air is a very good insulator. Therefore, the chambers provide good thermal insulation of the profile.

The best plastic windows have a large chamber in the center of the profile, which is called the "reinforcement chamber".

A metal U-shaped or square profile is inserted into this chamber, which performs the following functions:

  • gives rigidity to the whole structure;
  • increases resistance to wind loads;
  • increases resistance to weight loads;
  • saves the window geometry.

Additional chambers on one of the sides of the profile provide a tighter fixing of the fittings. The minimum requirements for a plastic window include three chambers and a depth of 60 mm. The best option for the Russian climate is a five-chamber profile with a depth of 70 mm. A high-quality PVC profile is made of a homogeneous material that is resistant to deformation, oil, moisture, solvents and can withstand sudden temperature changes. Its surface should be smooth, even, without graininess and mechanical damage. The exception is profiles with a surface that imitates texture natural materials, for example, a tree.

The plastic profile is absolutely odorless and does not melt in direct sunlight. In addition, it has excellent refractory properties. Unlike aluminum profiles, plastic can be used to produce window structures the most unusual shapes and sizes: round, triangular, arched, trapezoidal. The most popular companies producing profiles for plastic windows are REHAU, KBE and NOVOTEX.

  1. REHAU - one of the oldest manufacturers of PVC windows. Window designs of this brand occupy the highest positions in sales and quality. after-sales service. Brand products are often installed in medical and preventive institutions, since only safe materials are used in the process of its manufacture.
  2. KBE Profile - a modern representative of plastic windows. It is manufactured using the latest innovative technology without the use of lead. The cost of structures from the KBE profile is 10% lower than branded counterparts.
  3. Windows from the NOVOTEX profile belong to the budget category. It is distinguished by good quality characteristics, perfect whiteness of the front surface and the presence of an original glazing bead with a beveled angle of 35 degrees.

Review-comparison which windows are better KBE or REHAU can be seen.

double glazing

When choosing plastic windows, customers pay great attention to the profile, forgetting about the existence of double-glazed windows. The profile occupies only 20% of the area of ​​the product, and the double-glazed window the remaining 80%. When choosing high-quality windows, you should pay attention to the product as a whole. To understand which plastic windows are better to put in an apartment, it is necessary to take into account the following factors and preferences:

  • whether permanent residence in the premises is planned, or its operation as a warehouse or office;
  • whether the density of the frame and its color are a priority;
  • family budget opportunities;
  • the intensity of the light transmission of the window.

A double-glazed window with a thickness of 32 mm is installed in windows of the "standard" class on 3 glasses, one of which is energy-saving. Windows of the "elite" class have a two-chamber double-glazed window 40 mm thick with one energy-saving glass, plus chambers filled with heat-saving gas - argon. In general, such a window is 15% warmer compared to a "standard" class window.

To improve energy efficiency, silver oxide is applied to one of the glass surfaces during the manufacturing process, which reflects infrared radiation. And ordinary glass passes most of the solar energy, releasing heat rays with it. To improve safety and protective properties window structure, it is recommended to install a double-glazed window made of laminated shatterproof glass covered with protective films of class A1, A2 or A3.

A single-chamber double-glazed window consists of two glasses. The distance between the panes is determined by the size of the distance frame. The frame is based on a desiccant that prevents condensation from settling inside the double-glazed unit chamber. Due to the peculiarities of the Russian climate, it is recommended to install windows with a double-glazed window consisting of three panes. The distance between them is also determined by the distance frame.

Let's talk about how to choose plastic windows correctly. AT modern apartment all interior details should be carefully thought out, because they are a significant part of your life.

Therefore, the choice of such important detail The interior of your house, like windows, needs to be approached very carefully, paying attention not only to aesthetics, but also to reliability in operation. It is difficult to overestimate the importance of windows in a modern apartment, because it is through them that sunlight, air, as well as external sound sources.


How to choose good plastic windows

Let's take a closer look at modern metal-plastic windows and consider the advantages that make them so popular. One of the main advantages is soundproofing. Now the noise of the street will not prevent you from enjoying the comfort and coziness of your home nest.

Having installed metal-plastic windows in your house, you can be sure that even harsh winter warmth will reign in the house, since such windows compare favorably with a high level of thermal insulation.

Reliability and durability - no less important characteristics contemporary metal-plastic structures. Since the windows are not exposed to the summer sun, rain and frost, in other words, they are not exposed to atmospheric influences, and as a result they do not warp, do not crack, their service life is up to 20 years.

Also, metal-plastic windows are unpretentious in care - you just need to remember to wash them from time to time. detergent. A wide choice of shapes, colors, textures and design methods allows you to realize the most unusual design ideas, and just give the room a cozy and elegant look.

How to choose the best windows, when choosing between plastic and wooden ones, take combined ones, because they contain all the advantages and eliminate the disadvantages of these two types.

We made sure that metal-plastic windows are ideal solution for a modern, warm and cozy home. Now let's dive into the details. How to choose good plastic windows, the most common types of window designs are blind, tilt and turn.

Which window profile to choose

So, a blind window is a fixed, non-opening window. In operation, it is more reliable, since it does not have moving parts, but the room still needs to be ventilated, and therefore the combination of a blind window and a window that opens is popular.

Opening windows are divided into rotary and tilt-and-turn. pivot window is a structure that opens with doors inward, that is, traditionally.

More complex design is a tilt-and-turn window that opens both inwards, horizontally and vertically (tilts top part window). This design is more convenient, because you yourself choose how convenient it is to open the window at a particular moment. Which window profile to choose is up to you, of course, but the tilt-and-turn design is the most popular.

Depending on the size of the room, you can choose a single-leaf window (which consists of one window structure), a double-leaf window (it, respectively, consists of two window structures), and a three-leaf window. When installing windows, it is necessary, if possible, to avoid wide sashes, for the reason that they go far into the room and do not allow the use of areas of living space. In addition, the “heavy” sash creates an additional load on the fittings.

How many cameras should there be?

A very important point is the number of window cameras. The more chambers the window includes, the stronger and warmer it will be. Accordingly, if you want to protect yourself from the jokes of a harsh winter, it would be more profitable to choose a three-chamber double-glazed window, consisting of four glasses, between which three air chambers are formed.

The thickness of the glass is 4 mm, the space between the glasses is 10 mm. With simple calculations, we get the thickness of a three-chamber double-glazed window of 48 mm. If you are not afraid of frost, or in winter time the climate pleases with mild weather, you can stop at a one- or two-chamber window. But residents of panel houses need to take note that double-glazed windows do not provide optimal thermal insulation.

The space between the panes, except for air, is filled with inert gases or their mixtures to increase heat and soundproofing characteristics double-glazed window. The most commonly used are argon and krypton, which are obtained by separation from liquefied atmospheric air.

When choosing a double-glazed window, it is important to remember that the thermal insulation of a window directly depends on the tightness, thickness of the glasses and the distance between them. And tightness, in turn, depends on the quality of the sealant.

Cheap designs use a short-lived silicone sealant, which will cost twice as much to replace as its original cost.

What should be the glass

In modern windows, instead of ordinary glass, so-called low-emission (energy-saving) glass can be used, with a special coating with a layer of silver atoms.

Advice. You can check the privacy of windows in a simple way: Bring a lit lighter or match to the window. By the number of reflections of the light in the window, judge the number of cameras: if there are three reflections, then the window is two-chamber, and if four - three-chamber.

Also, using a match or a lighter, you can check for the presence of energy-saving glass - it does not cast a red, but a purple glow.

How long a new window will serve you depends on the thickness of the metal reinforcing profile that reinforces the PVC structure, which must be galvanized without fail, otherwise corrosion will begin to destroy it after a while.

Often, the cost of double-glazed windows is associated with the absence of galvanized iron. But, as the proverb says, we are not rich enough to buy cheap goods. When answering the question of how to choose the best windows, you need to remember that with savings, you can later spend more on replacement and repair.

accessories

A very important addition to the window design is fittings. Having spent money on windows, you should not save on latches, handles, turning mechanisms, and other trifles, otherwise you will suffer from skewed sashes that constantly jam and stop. Additional expenses will not hit your wallet, but will pay off a hundredfold.

White is considered the traditional color of double-glazed windows, but if there is a desire, the color and texture can be ordered for every taste: both in a different color and “under the tree”. Additional accessories are also purchased: mosquito nets, window sills, safety glasses, etc.

No less important than the quality of the windows themselves is the installation process, on which the quality of their operation largely depends. Therefore, it will not be superfluous to personally control the installation of windows.

Manufacturer

When choosing windows, special attention should be paid to the manufacturer. To date, the most famous and reliable manufacturers on our market are Rehau, Salamander, VEKA and others.

Rehau was founded in 1948 in the Bavarian city of Rehau, was the first company to replace common materials polymers. For more than half a century, Rehau has delighted customers with outstanding innovative technologies and high reliability.

The German company Salamander started producing profiles for PVC windows and doors manufacturers in 1973, and today the company is one of the leading European manufacturers of PVC profiles for window structures.

VEKA also German company, known in the CIS market for more than ten years. The company's products are different wide choice designs and variety of colors. Of the advantages of the company's window structures, one can confidently name strength, tightness and good ventilation. But Veka windows do not always come out of the battle with fifty-degree frosts with honor.

I hope we answered your question, how to choose plastic windows correctly and not regret your decision. Choose worthy and enjoy the warmth and comfort hearth!

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

The 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 equal? 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 “acquire” 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 - externally Atmosphere pressure presses the glass to the seals as tightly as possible. 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 size of air chambers window profile directly affect 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 an "over-the-top" design if, according to climatic conditions region, the purpose of the room in which it is planned to install windows, and its location, it is enough to limit ourselves to no less high-quality in 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 differs in absolute safety for health of the person and animals. 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 pieces of 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 indeed it was chosen high quality pvc window, it must be guaranteed for more than a dozen years without loss of any operational 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 external design home or interior space.

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 shapes, with one-sided or two-sided plastic lamination, which will give the window desired color or an interesting external texture - under noble 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, general scheme plastic window devices:

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 - everything basically depends on it. performance characteristics windows and durability.

  • 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 allowed in the kitchen or on south side buildings, 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 constructive 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 applied thin material, for example, 0.5 mm, or not having 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 lamination or two-sided, moreover, external and inner surface can be trimmed to 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. good qualities profiles differ, with acrylic coatings applied using the co-extrusion method - an additional protective and decorative layer is obtained, which at the same time becomes inseparable from the PVC base component. Another technology exterior finish is the application of colored acrylic varnish on 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 quality products which is accompanied by a manufacturer's warranty.

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 the quality foreign manufacturers, 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 plastic profile, so the value of the quality of the double-glazed window can hardly 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 the glass different thickness will never resonate.

Glass must be tempered, passed a special heat treatment after cutting it into right 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.

Even more safe 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 could be metal grid 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 this design according to the same principle as the number of cameras in the profile - for southern regions or for unheated rooms.

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 double-glazed window are possible various options glass layouts. 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 width(distance frames 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, it concerns the application on glass film coating 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 through large area window. 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 "fouri-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. Under no circumstances should you purchase products with plastic elements- they do not withstand any 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 elements fittings, which, for example, provide a stepped 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 choice of 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 may have different profile cross section. 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

Nothing less, and perhaps even crucial also has 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 independently measure the window opening 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:

  • presence own production, allowing to keep prices acceptable for customers for the product and services of the company;
  • 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 closed windows you can enjoy fresh air, wherein:

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

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

Second innovative product"Window Factory" - 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 retains heat inside the apartment, keeping it on the windowsill comfortable temperature, on average +6°C higher than that of 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 that are not specified in the concluded agreement.
