An article about high-quality window installation. All about plastic windows. Scheme of the window and a set of fittings

In this article I will try to tell you everything about plastic windows.

It is quite difficult to choose a high-quality plastic window, and even on a reasonable wall. The cost of a window is formed mainly from the type of profile and double-glazed window; branded fittings can also greatly change the price.

It is very difficult to figure out what profile you need, how many cameras a double-glazed window should have, etc. It is almost useless to ask this in manufacturing firms. Almost all firms will charge you the maximum, ie. you will be satisfied with the work, but it could be cheaper, because you used a more expensive profile and a double-glazed window. And it happens that windows cost you cheap, but in winter condensation appears on them, they freeze - this is not a high-quality window assembly that needs to be replaced and cannot be repaired. Although there are companies that value their reputation and can make you a quality window using the material you need for your conditions, which is why the cost of the window will be relatively cheap. Of course, the most optimal choice of window is the one installed by your friends, which has been standing for more than a year and has no complaints from the owners. You can safely order such a window and MOST IMPORTANTLY from the company that made the window for your friends.

If this is not possible, we will try to figure out what they will offer you when ordering a window in a company.
1 - the profile from which the plastic window will be made.
When choosing cheap profiles such as - VEKA, PROPLEX it must be borne in mind that they bend, it is not desirable to make a balcony module out of them (a door and a window to the balcony) or a window with an opening sash larger than 1.3 x 1.4 m.
When choosing cheap profiles such as - KBE, THYSSEN, REHAU these are more rigid profiles from which, in principle, it is necessary to make plastic windows and doors.
2 - a double-glazed window which happens one - and two-chamber. A chamber is a space between glasses filled with rarefied air and gas, which protect your home from noise and cold. If only two glasses are used in a double-glazed window, then this is a single-chamber double-glazed window. Accordingly, a two-chamber double-glazed window consists of three glasses. A single-chamber double-glazed window is suitable for windows overlooking a glazed balcony, as well as for very well-heated rooms, otherwise you need to install a double-glazed window that protects as much as possible from noise and cold.

To understand what combination of profile and double-glazed window you need, you need to decide on the conditions and tasks of the future plastic window.
If you need minimal insulation from noise and cold, which usually happens at the exit of a glazed and insulated balcony, then a 3-chamber profile and a 1-chamber double-glazed window will suit you.
If your house is well heated, but disturbed by street noise, then you will need a 3-chamber profile and a 2-chamber double-glazed window.
Full and capital protection against cold and noise when using a 5-chamber profile and a 2-chamber double-glazed window.

Let's try to figure out why the plastic windows of the house sweat in winter and what to do so that the windows do not sweat in the apartment. Today, this problem occurs frequently. When they say that windows sweat or fog up, it means that moisture collects on them. There may be several reasons for this, which we will consider in this article.

If it feels cold from a plastic window, then this reason is possible in the quality of the window manufacture, when the sashes do not fit snugly when closed. This is a factory defect that cannot be corrected - you need to call the manufacturer (if the window is under warranty) so that they change it.

It happens that the window is of good quality, but it is mounted with poor quality. Very often, the “jambs” of plastic window installers are to save mounting foam and not properly insulate the slopes, which is why the cold air of the street enters the room without any problems. Here you also need to call the manufacturer to fix the installation of the window.
If there are no visible reasons for the fogging of the window, then we recall the "school physics", when the temperature difference outside the windows and in the house is very large, then condensation forms on the window. Because the colder the glass in the window, the more likely it is that the vapor in the air will settle on its surface in the form of water droplets. In this case, it is necessary to ensure the ventilation of the room and a good hood, if we are talking about plastic windows in the kitchen.
Perhaps the "cruel joke" played with you, your elementary savings. Many have heard about multi-chamber double-glazed windows and various profiles for using the manufacture of plastic windows, but did not think or thought badly about how to choose plastic windows.

What to do so that the windows do not sweat in the apartment?
These tips are suitable if plastic windows sweat not from poor quality workmanship or installation.
As an option, simple, but not beautiful - ventilate the room more often.
Look where you have the battery, ideally it should be under the window, and not on the side. The temperature from the radiator must be higher than the air temperature in the room. If this is prevented by a window sill that cannot be replaced, then several holes 5-6 cm in diameter should be drilled in the window sill and decorated with decorative rings that can be bought at a furniture fittings store. Ideally, the window sill should not overlap the battery.
If you have indoor plants on your windowsill, try removing them. They can block the access of warm air from the radiator to the window.

In conclusion.
Windows themselves cannot release moisture, which means that it is taken from somewhere in the room. The air near the window is the coldest, and if its temperature is below the dew point, then window fogging is inevitable.

Plastic windows (PVC) Rehau made from polyvinyl chloride. The advantage of such windows is their resistance to physical and chemical influences. The special properties of this material provide designers with almost unlimited possibilities: a variety of colors, shapes and sizes. You can admire not only the view from the window, but also the view of the window itself.

Plastic windows from the Rehau (rehau) profile provide reliable sound insulation.
These windows are very durable. Therefore, they are often called metal-plastic.
Also, such windows are highly reliable and they are equipped with an anti-burglary system providing you with security from intruders.
And the main advantage of a window from the Rehau (rehau) profile is its high thermal insulation, which will not allow you to freeze in severe frosts.
The price is derived from factors such as the price of window components, the manufacturing process itself, raw material costs, delivery and installation. The production of such windows is a rather complicated and time-consuming process.
Prices for rehau windows are not exactly cheap, but the money spent on their purchase will pay off for you with more than their many advantages.

Plastic windows have long ceased to be a novelty, but, unfortunately, there are still cases when a lot of money spent on their installation is literally thrown to the wind: due to improperly selected design, poor-quality materials or unprofessional installation, such windows very quickly become unusable and, at best, require expensive repairs, and at worst, a complete replacement. We have prepared information about the most important parameters that you should definitely pay attention to when ordering and installing windows, and we turned to a professional expert from the Archdialog agency for advice.

Well-installed high-quality plastic windows should serve faithfully for many years, reliably protecting your home from bad weather and street noise. They have a number of advantages compared to outdated wooden frames: they do not rot or rust, they do not dry out from the sun and do not swell from moisture, they do not require regular puttying and painting, they have convenient opening mechanisms, they are reliable, comfortable and durable in operation. The disadvantage of plastic windows can only be called their flammability and very heavy weight. To choose windows that meet the best specifications, you need to pay attention to several parameters, which we will discuss in detail.

Design

Plastic or PVC windows consist of a multi-chamber plastic profile hollow inside with metal reinforcement, double-glazed windows and fittings.

In a PVC profile, there are usually from 2 to 8 hollow chambers. It is believed that the thicker the profile and the more cameras it has, the warmer the windows. However, you should not overpay a lot of money for an extra number of chambers: plastic already has a very low heat transfer, therefore, to save money in our climate, it is enough to install high-quality windows with a three-chamber profile, double-glazed windows and two sealing circuits - this will ensure effective heat preservation inside the room in a cold season.

Double-glazed windows

Preservation of heat in the house is largely ensured by properly selected double-glazed windows. In residential premises, it is most reliable and most expedient to install windows with double-glazed windows (i.e. with 3 glasses and 2 air chambers between them). Compared to double-glazed windows, this is a more expensive option, but the difference in price will be justified by significant savings on heating and greater comfort in the winter.

Single-chamber double-glazed windows (with 2 glasses and 1 air chamber) significantly lose to double-glazed windows in terms of heat retention, but their undoubted advantage is their lighter weight and affordable price. Windows with double-glazed windows are recommended to be installed in regions with a very warm climate or in non-residential premises: in summer cottages, balconies, loggias, verandas, etc. Some manufacturers claim that their single-pane double-glazed windows filled with an inert gas or, conversely, with highly rarefied air (“vacuum”) inside retain heat as efficiently as double-glazed windows, and are much cheaper. However, do not believe these marketing tricks - it is better to pay extra once and order a high-quality double-glazed window than to suffer and suffer from the cold for many years.

Three-chamber double-glazed windows (with 4 glasses and 3 air chambers) are very heavy, they require especially durable fittings and special installation technology. In addition, the four glasses included in their composition transmit light much worse compared to single-chamber and double-glazed windows. It is recommended to use them only in the extremely cold climate of the Far North, and preferably on deaf, non-opening windows.

It used to be that the wider the air chamber of a double-glazed window, the less heat would go outside through the window. But now it has already been proven that a thick air gap does not always guarantee effective heat retention: according to the law of convection, warm air from the inner warm glass will rise up, and cold air from the outer cold one will go down, replacing it. Thus, inside the double-glazed window there is a constant circulation of air masses, which leads to significant heat loss. Therefore, modern manufacturers are trying to reduce the distance between the glasses.

Reinforcement

To ensure additional strength of a heavy window structure, the PVC profile is reinforced with an insert, the thickness of the metal in which, according to German standards, must be at least 1.5 mm for ordinary windows and 2 mm for large windows. It is advisable to choose a PVC profile with a closed rather than a U-shaped reinforcement - it is much stronger and more durable.

accessories

When ordering plastic windows, it is very important to choose high-quality strong fittings, especially for structures with double-glazed windows: weak fittings simply cannot withstand the weight of a heavy frame with three glasses, and within a few months after installation, serious problems can begin with windows, such as a draft, frame distortion Difficulty opening and closing.

Additional functions

When ordering plastic windows, you can choose the most suitable option for each dwelling. For example, if your windows overlook a noisy road, it is very useful to take care of additional soundproofing. It is achieved by installing a double-glazed window with different glass thicknesses and different widths of air chambers between the glasses, which will dampen the resonance. The function of the upper winter ventilation, the profile with built-in ventilation, the mosquito net and the opening regulator ("comb") will be very useful additions to the new windows.

What to look for when choosing

To avoid many problems, it is better to order windows from reliable, reputable companies. After all, in addition to the high quality of the windows themselves, you need confidence that they will be installed correctly: the vast majority of problems with plastic windows occur not so much because of their poor quality, but because of unprofessional installation. Serious companies have a quality certificate for their products and give a guarantee on their windows for at least 5 years. Another household recommendation is to take someone you know who has experience in ordering windows as an assistant, so that he, on occasion, can advise you or clarify some important details.

Window adjustment

During operation, any, even the highest quality windows sag over time due to heavy weight and constant loads, their mechanisms begin to work poorly, the frames shift and cease to fit snugly to the base. Therefore, all windows require periodic adjustment. If it blows from the window, its handle does not turn well or there are difficulties with opening and closing, this is an indicator that it is time to make an adjustment. You can adjust the window both independently and by inviting a professional master to your home.

PVC profiles gradually replaced wooden windows, which moved from the lower segment to the higher segment. Now the cost of a set made of wood is at least 20% more than that of polyvinyl chloride. Disputes between supporters of different materials do not subside to this day. Many people love wood for its appearance, environmental friendliness and durability. Oak windows, the most expensive option, will last up to 90 years versus 30-40 years for plastic. From an aesthetic point of view, wood is also superior to plastic. Nat...

The great discovery took place in the 60s of the last century: German technologists created the world's first plastic windows. To this day, the same materials are used as 50 years ago. The basis of the whole process is a compound called PVC for short, that is, polyvinyl chloride. In our country, these foreign inventions appeared relatively recently, in the late 90s. And met with great resistance. Only in the last decade, plastic profiles began to spread ...

The myths associated with the danger of PVC profiles are gradually fading away. Even former opponents install plastic windows, and it is difficult to find an apartment where the old wooden frames still remain. Nevertheless, the safety of plastic is still in doubt in some cases. Do windows emit harmful substances? Can they withstand extreme heat or cold? And how reliable is the protection against thieves? These questions are regularly asked by customers before installation. Where did they go...

Currently, wooden buildings are popular. However, for glazing such buildings, plastic windows are most often used, most likely due to their prevalence, as opposed to the more logical use of wood here. If you decide to install plastic windows in a wooden house, you should take into account a number of characteristics so that the installation process in this case goes as smoothly as possible. It should be borne in mind that all wooden ...

Double-glazed windows are filled with inert gases in order to reduce heat loss. According to experts, a double-glazed window filled with such gas retains heat in the room by 40% more. Krypton is much more expensive than argon because it has a thermal conductivity 1.5 times less than argon and 2.5 times less than air. Therefore, the heat transfer resistance of such a double-glazed window is quite high. Many people are concerned about the question of whether the gases inside such glass will cause harm ...

PVC (polyvinyl chloride) in its pure form is too brittle for the production of plastic windows, and therefore it is not used for these purposes. In order to make it a full-fledged material for the manufacture of window structures, you need to add special substances to the PVC composition. For example, lead salts are present in the composition to give the material strength and rigidity. Recently, the lead salt has been replaced by a calcium or zinc salt. They give the PVC material strength, moisture ...

Plastic windows - the best invention for the Russian winter

It should be noted that winters in Russia are severe. Every time with its onset, we think about how to make the room warmer. Glazing it with plastic windows plays a big role in keeping the heat in the room, as well as saving money on heating. In order to make the room warmer, special attention should be paid to the choice of double-glazed windows, which have additional heat-saving properties. Today, the most common are...

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 buildings, 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 - 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 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 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 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, 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 located 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 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 "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. 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. Extremely much depends on this “boundary” - the maximum possible tightness of the closure, thermal and sound insulation, protection of fittings from dust and dirt that can cause 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 disturbed.

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

When installing window sills, they are usually loaded with weights while the foam dries. Often water cans are used as cargo. There is nothing special about this, except for one small trifle: according to the well-known law of physics, a spherical glass form (in this case, a jar) filled with water turns into a magnifying glass, which can easily focus the sun's rays on the plastic surface and burn a large hole in it. If you are not satisfied with this outcome of the case, just cover the jars from the sun with cloth or paper.

In some panel houses, radiators are hidden in the wall. If you have to install a plastic window in an apartment of just such a house, be extremely careful when dismantling the old block and especially the window sill! The fact is that the window sills are fixed from below with metal corners, which are aimed at the concrete wall with dowels with a special gun. Do not try to pull these dowels out of the stove: they may be driven into the heating pipe. It is better to cut the corners with a grinder or simply bend under the windowsill if a grand flood is not in your plans.

If you are transporting a PVC window yourself, be aware that it is not desirable to turn it upside down. The fact is that some manufacturers of PVC windows do not install spacers at the top of double-glazed windows, violating the assembly technology. In the inverted position of the window, the double-glazed window can move and rest at an angle against the metal part of the impost attachment, which causes chips to form at the point of contact on the glass, from which cracks can go along the glass - if not immediately, then later: for example, in severe frost.

In winter, in severe frosts, an ordinary soft toy, fur hat, pillow, etc. can cause damage to the glass pane of the window. Such a nuisance can occur if any of these harmless objects are placed on the windowsill and leaned against the glass. The area of glass, closed from the influx of warm air, after a while will cool down to a temperature much lower than the temperature of the adjacent surface, and the glass will burst. By the way, in the same way, you can accidentally ruin the windshield in the car!

To care for PVC windows, it is recommended to purchase first-aid kits with a set of special tools, of which oil is more often used to lubricate fittings and silicone grease for rubber seals. They also run out the fastest. In order not to spend extra money on buying a first-aid kit, use alternative means: for accessories - oil for sewing machines (available from any housewife), and for rubber bands - liquid (not spray) silicone lubricant for rubber car seals. The effect is the same and lasts longer.
