PVC profiles gradually replaced wooden windows, which moved from the lowest to the highest segment. Now the cost of a set made of wood is at least 20% more than that of polyvinyl chloride. Disputes between supporters different materials continue to this day. Many people love wood for 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...

A great discovery occurred 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 entire 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 they met great resistance. Only in the last decade have plastic profiles begun to spread...

Myths associated with the dangers of PVC profiles are gradually disappearing. Even former opponents are installing plastic windows, and it is difficult to find an apartment where the old wooden frames still remain. However, the safety of plastic is still questionable in some cases. Do windows emit harmful substances? Can they withstand extreme heat or cold? And how reliable is the protection against thieves? These are questions that customers regularly ask before installation. Where did they come from...

Currently wooden buildings are popular. However, plastic windows are most often used for glazing such buildings, most likely due to their prevalence, as opposed to the more logical use of wood here. If you decide to install plastic windows in wooden house, You should consider a number of characteristics so that the installation process in this case went as smoothly as possible. Please note that all wooden...

Double-glazed windows are filled with inert gases 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 fragile 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 PVC composition special substances. For example, lead salts are present in the composition to give the material strength and rigidity. Recently, lead salt has been replaced by calcium or zinc salt. They give PVC material strength, moisture resistant...

Plastic windows are the best invention for the Russian winter

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

When installing window sills, they are usually loaded with weights while the foam dries. Cans of water are often 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 mold(in this case, a jar) filled with water turns into a magnifying glass, which can easily focus the sun's rays onto the surface of the plastic and burn through it big hole. If you are not happy with this outcome, simply cover the jars from the sun with cloth or paper.

In some panel houses heating 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 from below are fixed with metal corners, which are aimed at the concrete wall on dowels. Do not try to pull these dowels out of the slab: they may become driven into the heating pipe. It’s better to cut the corners with a grinder or just bend them under the windowsill if a huge flood is not in your plans.

If you transport a PVC window yourself, know that it is not advisable to turn it upside down. The fact is that some manufacturers of PVC windows do not install spacers at the top of the double-glazed windows, violating the assembly technology. In the inverted position of the window, the glass unit can move and rest at an angle against the metal part of the impost fastening, which is why chips form on the glass at the point of contact, which can cause cracks in 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. may cause damage to the glass unit of the window. Such a nuisance can occur if any of these harmless objects are placed on the windowsill and leaned against the glass. A section of glass, closed from the influx of warm air, will after some time cool to a temperature much lower than the temperature of the adjacent surface, and the glass will burst. By the way, you can also accidentally damage the windshield of a car!

To care for PVC windows, it is recommended to purchase first aid kits with special means, of which oil is most often used to lubricate fittings and Silicone Grease for rubber seals. They end the fastest. In order not to spend extra money on buying a first aid kit, use alternative means: for accessories - oil for sewing machines(any housewife can find it), and for rubber bands - liquid (not spray) silicone lubricant for rubber car seals. The effect is the same and will last longer.

Most people who have planned to replace their old, cracked windows with new plastic ones, for some reason prefer to do this in the warm season, citing the fact that in winter it is impossible to perform the same actions at the same high level. This statement is completely false. The quality of installed plastic windows does not depend on the time of year, but on the professionalism of the craftsmen. By choosing a reliable company offering its services in this area, you will provide your window openings with excellent sound insulation and tightness.

They have already become so familiar to us that we don’t even think about when exactly they appeared. But 50 years ago no one knew what it was. You will be interested to know that the history of polyvinyl chloride (PVC) goes back to 1835. It was then that the American chemist Regnald synthesized a substance that became a revolutionary breakthrough in future production.

There is an opinion that the more cameras in a double-glazed window, the better. At the same time, of course, everyone wants to buy PVC windows cheaply. In fact, three-chamber double-glazed windows are only advisable in harsh northern conditions. In central Russia, two-chamber plastic windows are optimal. But even five-chamber ones continue to appear on the market, which is hardly justified in residential buildings. Let's consider how the installation of three-chamber double-glazed windows improves plastic windows.

The Air-Box company produces air-conditioning and ventilation devices window valves. These products are easy to install and are accessible means restoration of air exchange. Most importantly, they prevent air quality from deteriorating and indoor humidity from increasing. Condensation and mold do not form and human health is preserved. Breathable windows are new level comfort.

In 1873, the production of high-quality German window fittings began, marketing them under the brand name AUBI. AUBI received the "Ludwig Erhard Award 2000" (reward for comprehensive quality assurance), was named "Factory 2000" in the category "Best Serial Manufacturer in Germany 2000" and was able to become the owner of the "Best International Factory Award 2000" (reference test-competition for achievements in entrepreneurial activity).

Affordable prices for plastic windows

There is an opinion that cheap windows PVC- This is a compromise between price and quality. Many manufacturers are taking the path of reducing the cost of production by saving material or making certain changes to the design. Sometimes it's not in the best possible way affects the wear resistance of window blocks.
But there are other reasons why the manufacturer offers to buy high-quality cheap double glazed windows:

Of course, you want the plastic windows in your home to last as long as possible and not lose their attractiveness! To increase the service life of plastic windows, caring for them is simply necessary! Subject to simple rules care for PVC windows and doors, they will serve you for many years! Operation and care PVC products:
We recommend:

IN finished form The price for plastic windows consists of two parts: its components and installation. These two components make up both the quality of the PVC window and its successful work for many years. Trying to buy PVC windows cheaply, people usually ask themselves the main question: how to save money without losing quality. The opinion spread by many manufacturing companies that PVC windows are cheap is bad is not always true. Let's try to figure this out.

In practice, aluminum, wood, plastic profiles, as well as their combinations, are used. The greatest demand is still for plastic windows, the production of which is well established in many regions and, in particular, in the Moscow region (PVC windows are much easier to buy cheaply here due to the large number of offers).

The variety of windows is great. The profile material can be:
aluminum (quite durable, but freezes strongly in winter, so aluminum profiles are made with a thermal break);
wooden (has good thermal conductivity, but, especially with outside, requires additional care);
plastic (with at least three hollow chambers) or metal-plastic (reinforced steel frame).

Which PVC profile is better

Ten years ago, the answer to the question of how to choose and which is best to buy plastic windows would have been clear: from a German profile. Today the picture has changed radically. Since Russian enterprises began to develop extrusion production, many Russian manufacturers window systems offer windows made from domestic profiles. This has significantly reduced the price of a finished PVC window without losing its quality.

How to improve the performance of PVC windows

Modern plastic windows (produced in the Russian segment, in any case) are designed to provide maximum heat, noise and light insulation. The main role here is given to the double-glazed window, but simply increasing the number of glasses more than three in a double-glazed window does not give the expected result. The design becomes heavier, which leads to a decrease in the service life of the fittings, and the amount of daylight transmitted decreases. There are more technologically advanced ways.

Glazing of balconies and loggias with aluminum profiles
In order to decide which balcony windows are best to choose, you just need to determine for what purpose you want to use the data square meters and there are several possible answers and, depending on the choice, solutions:
- If you just want to glaze your balcony from noise, wind, rain, snow, dust and other bad weather, then cold glazing is suitable for you.

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

Owners of apartments and private houses of old construction, at the slightest opportunity, try to replace imperfect wooden structures for modern windows. At first glance, there are no problems with this; in any region there are many large and small companies working in this field. But can everyone be trusted, and are the windows offered for purchase of equal value? Alas, but in this segment construction business there are quite a few "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, you need to clearly understand how to choose PVC windows so as not to be disappointed in them after a few months.

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

What they say about PVC windows, and is this really true?

It happens common the opinion is 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 heat-proof light transmitting the design is very difficult, although high-quality double-glazed windows and a reliable sealing system can significantly increase the thermal resistance of the window. However, any window design also involves installation seams, which always, to some extent, serve as “cold bridges.”

What we can say with confidence in this matter is that the level of insulation of premises with the installation of high-quality plastic windows will increase significantly.

The next “myth” is that the air is completely pumped out from the space between the glasses, creating a vacuum 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 against the seals as tightly as possible. This also gives the effect of increasing heat and soundproofing 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 glass unit, which effectively dampens sound waves.

How do you feel about the statement that installing double-glazed windows provides absolute suppression of noise from the street?

You can’t completely believe in this either. To a greater extent, the design of PVC windows “cuts” high frequencies, but low-frequency noise, which also spreads through vibration, unfortunately, finds its way. So, if construction equipment is working outside the window, or there is a busy highway nearby, then the noise cannot be avoided.

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

A closed PVC window provides complete sealing of the room.

This is another persistent misconception. With a high-quality multi-level sealing system, we can talk about the window’s impenetrability for drafts, for exit warm air from the apartment, but this is still far away not tight.

Another erroneous opinion is that the wider the glass is placed on a double-glazed unit, the better the quality of the window.

The distance between the glasses is not a value taken from the ceiling. Exists a complex system thermal engineering calculations, which gives rather paradoxical results - an excessive increase in this distance leads to a sharp decrease in thermal insulation qualities. When producing windows, we adhere to optimal values, proven by theory and practice: for single-chamber double-glazed windows, the maximum thickness should be 24 mm, and for double-chamber windows - 44 mm.

The principle that when choosing a window there is no need to be limited in profile thickness and quantity is not always justified. air chambers in it: “The thicker the profile, the better the window, of course.”

To reason this way is tantamount to assert that that a big sledgehammer is much better and more useful regular hammer, because each of these tools has yours own purpose. Of course, the number and size of the air chambers of a 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 inevitably means an increase in the size and weight of the entire window structure, difficulties with its delivery and installation, and a rapid increase in price. There will be no point in paying extra money for a “super-sophisticated” design if climatic conditions region, the purpose of the room in which the windows are planned to be installed, and its location, it is enough to limit yourself to a no less high-quality, but more “budget” option.

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

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

Statements about the increased fire hazard of such windows are unfounded.

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

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

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

If a truly high-quality PVC window has been chosen, it should be guaranteed for decades without loss of any performance characteristics. Of course, the owners must follow the rules for its use and regular maintenance.

You may come across the opinion that plastic windows, with their standardized appearance, impoverish the design and can ruin external design home or interior design.

This statement does not stand up to criticism. This can be said by people who have never been interested in the existing variety of PVC. In reality, you can order a design of the most bizarre shapes, with one-sided or double-sided lamination of plastic, which will give the window desired color or an interesting external texture - like noble wood, metal, etc. In a word, there are more than enough opportunities to fit the window into the intended design.

PVC window selection options

First of all, for those who don't 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 schematically shows the main criteria for choosing a PVC window model.

Now about each of these parameters - in more detail.

Profile type and quality

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 their durability.

The material of manufacture 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 production costs, producing profiles with a wall thickness of, for example, 2.7 mm. It would seem unimportant, but the rigidity and wear resistance deteriorate sharply, and there is no need to talk about the long service life of such windows.

For regions with harsh winters you should choose a profile made of PVC with increased frost resistance. This is usually indicated by the additional index “M” on the marking.

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

The number of cameras is calculated by the width of the profile. If they stand horizontal lintels, dividing the cavity into several vertical compartments, then these are not considered additional chambers. Acceptable by standards minimal amount there are two cameras, but, as a rule, there are no such products due to their lack of demand. Typically used for installation in residential areas 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 purchase them if the climate of the region does not have severe winters, or in the case when the window will be installed, for example, to glaze 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 common, 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.

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

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

A profile made of corrosion resistant galvanized steel with a thickness of about 1.2 - 2 mm. If applied thin material, for example, 0.5 mm, or does not have anti-corrosion protection, then this can be considered a fiction - you cannot expect either rigidity or durability from such a window, and the insert is made only to “blur” the eyes.

The reinforcing insert can have a closed or open profile. Of course, with its closed form, the strength characteristics are much higher. However, this affects the total weight of the window structure and, of course, its cost. For small windows, you can limit yourself 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 abandon this option immediately - they will not provide any resistance to deformation, for example, 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. It is possible to perform single-sided or double-sided lamination, with external and inner surface can be finished in different textures .

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

There are profiles colored in the mass at the production stage, when pigment compositions are introduced into the original mass. Profiles with acrylic coatings applied using the co-extrusion method are distinguished by good qualities - an additional protective and decorative layer is obtained, which becomes an inseparable component with the PVC base. Another technology exterior finishing is the application of colored acrylic varnish to a white surface.

The profile manufacturing company is very important when choosing. It hardly makes sense to get involved with a manufacturer that is unknown or has already earned a bad reputation - you can find many examples where such windows disappointed their owners already in the first year of operation. If you decide to go for a replacement, then it is better to give up your savings for really high-quality products, which are accompanied by manufacturer’s warranties.

You can safely purchase REHAU, KBE, VEKA+ profiles. LG-Chem and MONTBLANC are completely trustworthy. In the premium window category, DIMEX and THYSSEN are traditionally leaders. Several domestic companies have appeared, trying to keep up with foreign manufacturers in terms of quality, for example, SOK (Samara window designs), DI FENCE or PROPLEX. It’s never a bad idea to go to the manufacturer’s official website and get acquainted with the features of the product – the raw materials used, technology, variety of models, guarantees provided. Well, when ordering, you should not be embarrassed to ask for 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, therefore, the importance of the quality of a double-glazed window can hardly be overestimated.

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

1 – glass with a thickness of at least 4 mm.

2 – air chambers formed between the glasses.

3 – spacer frames ensuring the same distance between the glasses.

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

5 – sealing adhesive composition that collects all elements into a common structure.

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

Thickness and quality of glass. Most models use 4mm thick glass. In the case where the windows face the street with increased noise levels, it makes sense to think about installing external glass with a thickness of 5 or 6 mm. This will significantly increase sound insulation qualities, since glass of different thicknesses will never resonate.

The glass must be tempered and have passed a special heat treatment after cutting it into right size. At the same time, tempered glass does not lose its light transmitting abilities and any other qualities. But, firstly, this significantly, by 5 ÷ 6, increases its strength characteristics, resistance to both impacts and bending or compression loads. Secondly, even if accidentally broken, it will crumble into small fragments almost correct form without sharp cutting edges.

An even safer option is laminated glass - triplex. They can withstand even a directed blow, resist a break-in attempt, and in the event of destruction they do not shatter into fragments. In addition, such glasses are much less susceptible to microvibration, which means 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 glass with electromagnetic protection. This may be a metal mesh or conductive film, which is connected to the ground loop. This measure helps prevent exposure to external electromagnetic radiation, to prevent leakage of information transmitted via radio frequencies.

Number of chambers and their width.

Double-glazed windows come in single- and double-chamber types. The single-chamber option is two glasses separated by a certain distance. The total thickness of such a package ranges 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.

Double-chamber, respectively, have three glasses and two air or gas layers between them. The thickness of such bags is usually from 32 to 44 mm. Thermal insulation and noise canceling The quality in this option is, of course, much higher, so it is best to choose it for residential premises.

Find out, and also consider the causes and solutions, from our new article.

In a two-chamber double-glazed window, various glass layout options are possible. So, they can be 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 - cameras have different widths(distance frames are used, for example, 6 and 16 mm), and the external 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 heating costs in winter and air conditioning in summer, we have developed special technologies. First of all, this concerns the application of a film coating or low-emission sputtering based on silver ions. Depending on the technology used, there are k-glass i—glass. 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.

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

The marking of such double-glazed windows is usually specified by a formula indicating the thickness of the glass, the type of coating (if applied) and the distance between them. For example, the designation "4i – 10 – 4 – 10 – 4 i" indicates 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 conservation are double-glazed windows that do not have thin air, but the injected inert gas (usually argon or krypton). The special molecular structure of these gases significantly reduces the thermal conductivity coefficient. For example, compared to a conventional one (with the same other characteristics), a double-glazed window with argon gives a significant increase of 5% in energy savings. And if used combined scheme, then this figure is even higher: on a double-glazed window "4 – 16Argon – 4i" we can talk about an increase of 10 ÷ 12%. The results will be even more impressive on double-chamber combined double-glazed windows.

There are glasses with a special sun protection layer, which is especially important in the 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.

Window operation diagram and fittings kit

The buyer has to decide how he sees it and how it should work. Basic principles the work is shown in the figure:

Basic window “working” diagrams

The schemes can be used either individually or in a certain combination, for example, a rotary opening plus a folding one for ventilation.

The number, shape and size of all glazed areas should be considered. Many owners are often tempted to have one large glass panel covering the entire area of the opening. However, it must be taken into account that this is a very heavy load to fastening elements. In addition, the larger the window area, the greater the likelihood of resonant transmission of sound waves, and therefore the lower soundproofing quality. It is more expedient to distribute a large area into several sections separated by imposts.

Correct and easy job The design 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 stand up to criticism, are never certified and will not last very long.

The fittings must be exclusively made of steel (best of all, alloy steel), so that it can withstand several dozen daily operating cycles over many years. At the same time, it must be perfectly adjusted, so that any family member can easily open or close the window.

The quality of the fittings is the key to reliable and long work window system

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

If there are young children in the apartment, you should inquire about 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 locks, rotation function limiters, mortise or overhead locks, etc.

One of the types of “children’s” locks - a child will not be able to open the window to a dangerous distance

There are also additional elements fittings that, for example, provide stepwise opening of a window, prevent it from arbitrarily slamming in a draft, prevent handles from closing incorrectly, etc. The fittings also include all handles, decorative overlays and other external decor items.

Self-respecting companies engaged 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 selection of PVC windows. Extremely much depends on this “frontier” - the maximum possible tightness of the closure, thermal and sound insulation, protection of fittings from dust and dirt that can cause abrasive wear.

Window systems can use one or more (up to three) sealing circuits. Depending on their location, they can be external, internal or intermediate. In addition to sealing the moving part, sealing elements must be located on both sides of the installed glass unit.

Seals can have different cross-sectional profiles. They are made from 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 relation to resistance to abrasive and deforming loads, cracking, delamination, etc. It is believed that the EPDM composite composition has the best performance indicators (translated into Russian, it has the complex name “ ethylene-propylene-thermopolymer-rubber"or EPTC).

How to choose a window installer company

No less important, and perhaps even decisive, is the choice of the company that should assemble and install the windows. There are many offers for such services, and it is important not to fall prey to 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” into clearly reduced prices - most often they are offered by fly-by-night companies, and after a year there will be no one to make claims on quality. You should definitely be wary 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, it is proposed to conclude the contract at the customer’s home.

If at telephone conversation you are asked to measure the window opening yourself to place an order - hang up immediately, without getting involved in any discussion, since there is no smell of professionalism here.

A reputable company should demonstrate in its office samples of the profiles and double-glazed windows it uses - usually split window models are installed for this purpose. 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 truly high quality and 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 encountered similar apartments and have developed the best options.
Customer wishes for window configuration. Not all the “whims” of the apartment owner can be fulfilled, and the manager’s task is to find a compromise solution, both in terms of “de-glazing” and in terms of operation patterns of the valves.
The direction of the windows to the cardinal directions, the location of noisy passages or, conversely, quiet courtyards, must be taken into account. This will make it possible to more accurately determine the number of profile cameras and the type of glass unit.
As a rule, issues regarding the installation of ebb and flow sills are resolved at the same time, sometimes it is immediately planned from PVC. Installation will almost certainly be offered mosquito net, regular invoice or roller shutter type.
A serious company will always accommodate a good customer and give him a significant discount if several windows are purchased and installed at once.
It is possible that the company’s list of 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 Window Factory company. Its competitiveness is determined by many obvious advantages:

availability own production allowing to maintain acceptable prices for the company's products and services to customers;
14 years of experience in the field;
warranty support for customers for 5 years after order completion;
friendly customer service system.

In addition to customer focus, the company has strengthened its leadership position through production innovative products, bringing to life completely new windows that are “attentive” to customer requirements.

The first technology, installed free of charge on products from 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:

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

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

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

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

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

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

retaining heat 40% more efficiently than multifunctional glass and 97% more intense than ordinary double-glazed windows;
in summer it reduces the penetration of natural heat from the street, keeping the room cool, while transmitting 30% more light;
in winter it retains heat inside the apartment, maintaining 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, Window Factory offers the option of installing tempered glass.

PVC profiles of double-glazed windows from the Window Factory are represented by individual REHAU designs that have passed all stages of quality control. Product fittings 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 independently choose the intensity of ventilation.

By choosing the innovative offers of the Window Factory, you maximize the efficiency of the installed glass unit, creating the most comfortable atmosphere at home.

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

It’s only when a detailed project is drawn up in the company’s office that completely satisfies the client, with all the drawings and diagrams, a list of materials and an estimate for assembly and installation, that the contract can be signed. In this case, it is necessary to stipulate the maximum permissible deadlines for completing all work, the responsibility of the parties for failure to fulfill obligations and whole line other important points.

Yes, it follows with special attention consider whether the payable estimate includes delivery of windows, lifting them to the floor, dismantling of old frames, garbage removal, use of consumables (for example, polyurethane foam). Often, inexperienced customers fall into such “traps” of unscrupulous companies, who then, during the installation of the window, find themselves faced with 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

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 according to a reasonable wall. The cost of a window is determined mainly by 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 chambers a double-glazed window should have, etc. Asking this to manufacturing companies is almost useless. Almost all companies will charge you the maximum, i.e. you will be satisfied with the work, but it could be cheaper, because... you were given a more expensive profile and glass unit. And it happens that the 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 quality window using the material required for your conditions, which is why the cost of the window will be relatively cheap. Of course, the most optimal choice windows, this is the one that your friends have installed, which has been standing for more than a year and has no complaints from the owners. You can safely order such a window and the MAIN THING 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 windows from the company.
1 - profile from which the plastic window will be made.
When choosing cheap profiles such as - VEKA, PROPLEX It is necessary to take into account that they sag; it is not advisable to make a balcony module from 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, plastic windows and doors need to be made.
2 - a double-glazed window that can be single- or double-chamber. The chamber is the space between the 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 it is a single-chamber double-glazed window. Accordingly, a double-glazed window consists of three glasses. Single-chamber double-glazed windows are suitable for windows facing glass balcony, as well as for very well-heated rooms, otherwise you need to install a double-glazed window that provides maximum protection from noise and cold.

To understand what combination of profile and double-glazed window you need, you need to decide on the conditions and objectives of the future plastic window.
If you need minimal insulation from noise and cold, which usually occurs 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 street noise bothers you, then you will need a 3-chamber profile and a 2-chamber double-glazed window.
Complete and thorough protection from cold and noise when using a 5-chamber profile and a 2-chamber double-glazed window.

Let's try to figure out why plastic windows at home sweat in winter and what to do to prevent windows from sweating in the apartment. Today, this problem occurs frequently. When they say that windows sweat or fog up, they mean that moisture collects on them. There may be several reasons for this, we will look at them in this article.

If a plastic window smells cold, this could be due to the quality of the window, when the sashes do not fit tightly when closed. This is a manufacturing defect that cannot be corrected - you need to call the manufacturer (if the window is under warranty) to have them change it.

It happens that the window good quality, but the installation is not high quality. Very often, the “jambs” of plastic window installers consist in saving polyurethane foam and not proper insulation slopes, because of which the cold air from the street penetrates into the room without any problems. Here you also need to call the manufacturer to correct the installation of the window.
If not visible reasons window fogging, then we remember “school physics”, when the difference in temperature 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 greater the likelihood that steam in the air will settle on its surface in the form of water droplets. In this case, it is necessary to ensure ventilation of the room and good exhaust, if we are talking about plastic windows in the kitchen.
Perhaps your basic economy played a cruel joke on you. Many have heard about multi-chamber double-glazed windows and various profiles, to use the manufacture of plastic windows, but did not think, or thought poorly about how to choose plastic windows.

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

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

Plastic windows (PVC) Rehau are 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 will be able to admire not only the view from the window, but also the view of the window itself.

Plastic windows made from the 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, ensuring your safety from intruders.
And the main advantage of a window made from the Rehau profile is its high thermal insulation, which will not allow you to freeze in severe frosts.
The price is derived from the following factors, such as the price of window components, the manufacturing process itself, the cost of raw materials, delivery and installation. The production of such windows is a rather complex and labor-intensive process.
The prices for Rehau windows are not exactly cheap, but the money spent on their purchase will be more than repaid to you by their many advantages.
