What a window profile to choose. Types of window profiles, Veka, Kbe, Rehau. Which profile is better: rehau, kbe or novotex

Plastic windows firmly occupy a leading position. They differ high levels The heat and sound insulation, besides, provide the ability to choose accessories, ways to open the window and profile color. You can also choose a glass pack with a necessary number of cameras. But few people think that it is the window profile that ensures the strength and durability of the whole design. In the article, we compare different on the characteristics and manufacturers profiles plastic windows.

General information about the profile of plastic windows

On average, the thickness of the plastic windows profile varies from 58 mm, and up to 86 mm, but some firms produce products with a width of 127 mm.

Its inside of the hollow, but is divided by jumpers creating several aircases. Special technical calculation determines their size and location. The wider the profile, the greater the number of cameras that increase the heat-power properties. Another feature of the profile system is the filling width that determines which type of glass package can be installed in the profile. They are one- or two-chamber species, the width of the glass in the standard double-glazed windows is 4 mm (M1 M1).

Each cavity has its purpose:

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

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

• coextrusion method - multilayer films create a certain barrier, allowing the product to withstand dynamic loads without damage;

• lamination - with imitation texture, for example, under marble or tree;
• monthly staining.

PVC-profile characteristics for plastic windows

Material

• This product is made of a variety of plastics - white polyvinyl chloride.
• The material is characterized by high resistance to chemical exposure to alkalis, solvents, acids and mineral oils.
• It is harmless to humans and the environment.

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

Design

The inner part of the plastic profile body is divided by longitudinal partitions, in turn they form cavities (air chambers). The minimum number of chambers in the profile - 3, the maximum - 8. The number of chambers determines the degree of thermal insulation and sound absorption of the window, the more air cavities, the higher these indicators. Immediately it should be noted that 3 and 5 chamber profiles are popular with popularity.

Reinforcement

To give stiffness, the profile additionally reinforced. The metal frame provides the necessary strength of the design and reliability when operating the window. Galvanized steel is used to reinforce the profile, therefore it is not deformed when the temperature drops or other environmental impacts.

• Mr.-shaped reinforcement - metal insertion is installed along two walls;
• P-shaped reinforcement, where metal reinforces three walls;
• A closed type of reinforcement - the metal insert is located along the four walls.

For window structures that have double-glazed windows in size up to 1900 mm in height, the P-shaped reinforced profile is suitable. However, for plastic windows of large dimensions, for example, for a loggia or balcony, a profile with closed reinforcement is required.

Profile class

The thickness of the profile walls defines its belonging to a specific class:

• Class A - the thickness of the profile walls should be at least 3 mm;
• Class B - profile, where the wall thickness is from 2.5 mm;
• Class C - abnormal wall thickness.

As a result, the width of the profile of plastic windows directly depends on its class. What he is higher, that respectively wider profile.

Comparison of manufacturers of plastic windows profiles

In the Russian market, many both domestic and foreign manufacturers represent their products. The leading positions in the rating of profiles for plastic windows occupy the company:

• Germany - Rehau, Veka, Kbe, Salamander, Schuco, Kommerling;
• Slovakia - INTERNOVA;
• Korea - LG Chem;
• Belgium - DeceUninck;
• Russia - Montblanc and Proplex.

Veka.

• The profile is produced in German technology in Russia, they always correspond to the class A, suitable for all regions, with any climate.

• The Russian-Austrian company is equipped with a production base, where development is underway and the latest technologies are being implemented.

• The Mont Blanket line contains 6 types of profiles, where the mounting width is from 58 mm to 120 mm, cameras - from 3 to 6.
• The durability of the profile system (60 years) is achieved with the help of specially designed operational characteristics for the harsh climate.

Proplex

• The plant located in Podolsk produces a profile on German equipment on Austrian technologies.
• These products are manufactured by a width that can be from 58 mm to 127 mm, cameras - from 3 to 6.
• The original recipe allows you to make a high-quality profile, characterized by shock viscosity and special whiteness.

Also compare the characteristics of the profiles of plastic window can be on the table below below.

Profiles of the German company KBE

It's believed that german profiles Plastic windows exceed the products of other manufacturers and quality, and whiteness, and technical characteristics. They do not lose their properties even during the long operational period, perfectly withstand almost any dynamic loads and substantial temperature differences (from -50 ° C to + 50 ° C).

The company KWA produces and supplies 2 types of the most sought-after profiles: Kves standard and Kve expert.

Kwe Etalon - three-chamber profile

• Mounting width is 58 mm;
• the width of the facial walls is 3 mm;
• the glass thickness can be up to 34 mm;
• 3 cameras in the frame, sash, impost (horizontal and vertical windows crossbars);
• can be used in harsh conditions (-60 ° C);
• service life - 40 years;

Benefits:

• with a profile width of 58 mm, it has 3 air chambers, their size and optimal position provide heat transfer resistance. Such windows have a high degree of tightness that exceeds existing requirements Gosta at 5 (!) Times, which guarantees the complete absence of dust and drafts indoors;
• two hermetic sealing pads provide excellent sound insulation (up to 46 dB). The profile is additionally equipped with horizontal jumpers, thereby enhanced the castle fortress when the window is closed;
• in the Cve profile, the ribbies are installed, which provide additional strength of the window structure. Also improved rigidity allow special stops with which the exact location of the reinforcing metal insert is achieved.

Kve Expert - Pleister Profile

• The mounting width is 70 mm;
• the width of the facial walls is 3 mm;
• the thickness of the glass is up to 42 mm;
• 5 cameras in the frame and sash, 3 or 4 in the impost (horizontal and vertical windows crossbars);
• Suitable for use in harsh conditions (-60 ° C);
• the contours of the seal correspond to the class A;
• service life - 40 years;
• in the manufacture, environmentally friendly materials are used, lead does not contain.

Benefits:

• putty-chamber build allows you to achieve better meaning Thermal insulation, such a profile is able to hold heat by 20% more than typical three-chamber systems. You can achieve excellent noise insulation by installing wide double-glazed windows in 70 mm profile;
• 13 mm grade groove allows you to establish anti-burglar accessories, thereby ensuring the safety of the room;
• cVA profile Expert has additional horizontal jumpers, thanks to which the handles and loops will be securely secured;
• when installing the installation seam, it turns out wider by about 20%, in turn, allowing additional insulation.

Approximate cost of windows from KBE profile

An important factor when choosing a glass package, its price. Often it is decisive, but the German window profiles of high quality can not cost cheaply. Below is an approximate market value in Russia.

• On average, a single-chamber two-dimensional window with dimensions of 140x130 cm, which has one deaf-type sash, and the other - the swivel-folding will cost:
  • from a profile 58 mm from 7500 rubles,
  • of 70 mm - from 10 000 rubles.

• The price of a two-chamber three-rolled window of 140x203 cm in size, which is the first sash rotary, central - deaf type, the third - swivel-folding will be from:
  • out of 58 mm profile 13000 rub;
  • from 70 mm 14500 rubles. and higher.

• When buying a balcony block with an open door with a size of 210x67 cm and a deaf window - 140x136 cm will have to pay at least:
  • from profile 58 mm 11000 rub;
  • of 70 mm from 13000 rubles.

What to pay attention to when choosing a plastic profile with a glass

In order to determine which the thickness of the profile is necessary, there are basic knowledge and a glass-paste, because up to 70% of thermal losses occurs through it.

This transparent element consists of 2 or more glasses, which are hermetically connected to the frame. A camera (air layer) is formed between them, filled with discharged air or inert gas, such as argon or crypton. This kind of filling is used in the production of energy-saving double-glazed windows.

Single-chamber glass is a design of 2 glasses of 4 mm and an air layer 16 mm, in abbreviated form is indicated - 4-16-4. Thus, its mounting width is 24 mm. The construction equal to 36 mm is obtained from a two-chamber glass package, which consists of 3 glasses of 4 mm and 2-layers of 10 mm - 4-10-4-10-4.

Therefore, the appropriate profile is selected for the required double-glazing. For example, the optimal solution for ordinary apartment Or at home will serve 5-chamber profile with 70 mm mounting width and 30 mm two-chamber glass, where heat transfer coating should be applied to one glass.

If the windows come out on the north side and the road loaded by cars, then in this case the following option is suitable: 5-chamber profile with a depth of 86 mm, supplemented with 32 mm double-glazed windows with a protective noise insulating film.

When the balcony (loggia) is combined with the surrounding room or it is planned to make a small office (rest room) from it, then the profile should be a 5-chamber with an 86 mm mounting depth, and the double-glazing is an energy saving, two-chamber with a width of no less than 40 mm.

For simple insulation The balcony will suit 60 mm 3-chamber profile and 30 mm single-chamber double glazing.

But it is not enough to simply choose the optimal PVC profile and a glass. Equally important to entrust installation finished window Professionals. Otherwise, no matter how expensive design, poor-quality installation annuls all its high characteristics.

I am glad to welcome your readers!

For your work, I installed many windows, but most often the quality was not very good.

The fact is that the main thing in the plastic window is a profile, but at first glance, on the view all the windows are the same. That is why I often faced the fact that customers choose a poor-quality profile.

What is the main thing in plastic windows? The basis of plastic windows - profile. A good profile is a guarantee of high-quality and reliable plastic windows.

How to choose a high-quality profile and what to pay attention to when choosing? I want to help you find a response in this article.

We go to the street or take the newspaper and, that we see the windows Kbe, Rehau, Veka, SalamaAHder, LG, Proplex, Barbooks, and the like. What is all these names? - This is the names of firms manufacturers of the window profile and nothing more, and your windows will produce completely different firms, and we know well that our manufacturers can make from the best raw materials.

And yet a little about the profile manufacturers. Ordering the windows you will hear from the manager that the windows (for example Kbe, Veka, Rehau, Salamander) are German windows of production of Germany - naturally the best and high-quality. What is the truth in these words, what is not? Of all those listed only by Salamander, 100% is produced abroad (so it and the price corresponding to), the rest have long been produced in Russia.

And about the production of the window profile. Most profile manufacturers factories built their plants in Russia. I was at the factories of the KBA and the century - beautiful plants, imported equipment, foreign specialists, imported raw materials, so that there is no big difference profile (I think this situation and in other plants of European manufacturers).

True, as always, there is "but". This is "but" the profile system produced specifically for Russia, i.e. Abroad, it is not used - it is only for us according to "our request." The advantage of this system is cheap, disadvantage - for reduced, the walls of the profile do thinner, respectively, the thermal resistance is less, the strength is less.

For the south, this is quite acceptable, in the middle lane - doubtful, in the north they can freeze. Usually this profile system is called object profile and used for glazing large objects - multi-storey residential buildings, industrial enterprises etc. There are still Russian and Turkish systems, but since we are going to glass our home, we will not consider in detail these systems.

Which profile I prefer personally, I can write further.

What do you think the profile is better? What is better Rehau or Barbokox? Century or relax? KBA or LG? etc.

The most difficult and annual question, to give an argued answer to which is almost impossible, I can only express my personal opinion. Once again, I emphasize - this is my personal opinion, and not advertising and the conversation will only go about the profile systems with which I worked.

A few words about Salamander (goes to no contest) - a good profile. The main advantage is made in Germany, the main drawback is expensive. It was produced, in Russia - was among the middle peasants.

Now, in order of profile systems produced in Russia:

Better than others:

• the number of customer reviews
• the number of marriage in the supply of plastic profile,
• seal
• conduct seminars, trainings and training courses for windows manufacturers.
• A variety of specialized systems.

Another advantage - sells a profile only on well-equipped plastic windows manufacturing enterprises that regularly checks and gives their certificate to these factories. Therefore, if you chose the plant working with this profile, then the probability of getting into an unpleasant situation is less.

I give second place. This company sells its profile only on well-equipped plastic windows manufacturing enterprises that regularly checks and gives their certificate to these factories. Therefore, if you chose the plant working with this profile, then the probability of getting into an unpleasant situation is less.

Honored 3 place.

Disadvantages:

• There are breakdowns in the supply of profile, profile marriage more often than - Rehau and Veka
• Sells a profile by any plants of plastic windows.

THYSSEN, LG, DIMEX

Motntblank, Propes, Barbokox

Share the last place in quantity positive feedback People who put windows, but very well suited for glazing balconies and loggias, as well as household premises. Dignity - low price.

P.S. With other profile systems did not work, so I can not say anything about them.

Which profile of the plastic window is better to choose? Competitions for choosing and rating manufacturers

The profile is the main element of any window, it is precisely the durability and reliability of the entire design that depends on it. At first glance, the profile for PVC windows from different manufacturers looks almost the same.

The difference in quality becomes obvious a series of several months (or even years!) Use when cheap windows begin to move and slots are formed in them. How to choose a good plastic profile for windows? What products of different brands differ from each other? And does it make sense to save on glazing, choosing a housekelate profile?

Profile for PVC windows: characteristics and types

The profile is the basis of the entire design, from which windows and frame flaps are made. It is they who define not only the appearance of the window, but also its strength. Common materials for the window profile - wood (cedar and larch) and aluminum.

But most often the profile for windows is made from PVC, or polyvinyl chloride. Such a profile is strengthened with metal inserts and inside has air cavities that increase the thermal insulation of the structure.

According to the European standard EN 12608 Sr, "non-controlled polyvinyl chloride (PVC-U) for the manufacture of windows and doors" and similar Russian GOST 30673-99 "Polyvinyl chloride profiles for window and door blocks. Technical conditions »Profiles are classified for a number of characteristics. In particular, according to the indicators of the thickness of the external and inland walls Allocate:

1. Class A profiles - have an outer walls with a thickness of 2.8 mm and the inner walls with a thickness of 2.5 mm; They provide the best thermal insulation and are considered an optimal choice.
2. Class B profiles have an outer walls with a thickness of 2.5 mm, internal - from 2.0 mm; Such windows are not only "colder", but also 15% less resistant to deformation.
3. Class C profiles are all others that are not suitable for standards A and B, there are no strict requirements.

Note!

There is a so-called "object" profile, which is intended for installation in non-residential industrial premises. It is impossible to use it in homes and apartments - because of the thin walls, it does not hold heat and unstable to the deformation.

This profile at first glance is no different from the usual - except on the protective film you can see the Object marking. Often unscrupulous companies offering very low prices for their goods, sell windows precisely from such a profile.

Choose the best profile for plastic windows

Determine "on the eye", which profile of plastic windows is better, not easy, but there are some features that can say a lot about his quality.

Uniformity profile

Plastic must be homogeneous and absolutely smooth. The grainy surface says that the windows were most likely made in handicraft conditions and are fake. The coating should also be homogeneous, without divorce and gradient.

By the way. In order not to buy a fake at the price of branded windows, pay attention to the factory labeling on the inside of the window box. It should be a stamp with the name of the manufacturer and a number of numbers: the shift number, the device for the production of PVC profiles and the date of manufacture.

Profile width

Most often, the company offers a plastic profile for windows with a width of 58 mm - this is a classic option, preferable for residential premises. The profile is 70 mm wide, this is often installed in high-rise buildings or where the climate is especially harsh. 90 mm wide profile refers to premium proposals, it is characterized by excellent heat and soundproofing characteristics. However, not all companies work with such products.

Thickness profile

The thickness of the profile must be the same, from 2.5 mm to 3 mm. However, for heavy window blocks, thin walls are not suitable - in this case, the welding seam is less durable, which means that the reliability of the entire structure suffers.

Number of aircases

The number of cameras depends on the profile width. A 58 mm profile may have a maximum of three cameras - which, however, is enough for the windows to maintain heat. 70 mm - three, four and even five cameras. The last of those mentioned (70-millimeters) are most in demand for glazing apartments and houses.

The norm for the 90 mm profile is six cameras. The more cameras - the warmer and quieter will be in the house. However, the sake of fairness should be said that the difference between, for example, a three-and-four-chamber package is not so significant.

Number of glass packs

You should not confuse the number of aircases in the PVC profile with the number of glass windows. The glass is a few glass sheets connected by contour using a special frame and sealants. Between the glasses, sealed cameras with air or other gas inside are formed.

Single-chamber glass is the easiest, it consists of two glasses and one air chamber between them. Such double-glazed windows are very lungs, suitable for glazing large openings, so they are often installed on balconies, loggias and terraces. However, they are not suitable for windows due to insufficient thermal insulation.

For home, summer cottages, office or apartments, it is better to choose a two-chamber glass glass, consisting of three glass sheets and two aircases. Three-chamber glass windows of four glass sheets are infrequently, they are severe and pass less light than other types of double-glazed windows.

Such windows are in demand only in the north, where the temperature in the winter can descend to -40 o C and below. At higher temperatures there are almost no difference between dual and three-chamber glass windows.

Helpful advice!

Choosing a plastic profile for windows, pay attention to the frame seals. There should be two, otherwise there will be condensate under the frame, and this spoils insulation and creates a favorable environment for bacteria and mold.

Window Profiles Rating: Comparison of key manufacturers

• Rehau.
  One of the most famous companies that has been producing reliable windows for more than half a century and is considered the main innovator in this area - Rehau engineers are constantly improving the design and configuration of the profile - so, the company pays great attention to ecology and energy-saving technologies. The company produces a profile with a width of 60-70 mm. Rehau products refers to the MIDDL class.
• Veka.
  Another German "giant", whose products are appreciated worldwide. VEKA produce a white and color profile that does not fade and does not yellow under the influence of direct sun ray. The seal is made of natural rubber, which does not freeze even under the influence of very low temperatures - valuable quality for the Russian climate. The line contains a model with a width of 58 to 90 mm. At the price of the VEKA window, comparable to Rehau.
• TROCAL
  This is a company with a long history, one of the pioneers for the production of plastic windows. The first model was released in 1954. For decorative finishes, the company offers a wide range of options - from lamination to acrylic coating. The profile is made according to the environmentally friendly technology of GreenLine and provides impeccable heat insulation. Profile width - 70 mm.
• Salamander
  This German company is not as well known as Kve or VEKA, however, Salamander products are never inferior to them in quality. The profile is produced exclusively in Germany, which means purchasing such windows, you can count on true European quality - at the European price. The company produces batteries from 60 to 76 mm wide.
• Kbe.
  One of the most popular German brands, which produces environmentally friendly windows recommended for installation in children's institutions and hospitals. Kve windows are different high quality and durability (there are up to 50 years old!), And in the line, both luxury models and economy options are present. Profile width - from 58 to 70 mm.
• Proplex
  Proplex is a Russian company that, despite youth, has already managed to establish wide production and significantly upgrade the window systems. The profile is developed with the participation of Austrian professionals and taking into account Russian conditions. With very good quality products, the company can still support affordable prices. Proplex offers models with a width of 58 to 127 mm.

This is only a small part of the manufacturers of plastic windows, in fact, their dozens, if not hundreds. What plastic windows are better? Choosing glazing, you should give preference to known brands, but it is necessary to check all the documentation - the famous brands are often formed. Branded windows at a low price - a sign that you may be trying to deceive.

Opinion edition

Even the best windows will last long, if errors were allowed when installing them. Better eclipse windows installed by professionals than expensive German windows mounted by lovers.

What profile plastic windows is better

What is a high-quality profile?

Pledge quality and durability metal-plastic window is a high-quality profile. Even if at first glance the entire profile for plastic windows is the same, in fact it is far from the case. Which profile for plastic windows is better, and how to choose the right window of VEKA RUS specialists.

Certificates

The entire profile from which the windows are manufactured - certified. The most significant is the RAL certificate, which certifies not only the type of product, but also its place of production. In other words, the profile of one brand, but made at different factories will not always have this certificate.

The certificate of quality management system ISO 9001: 2000 is issued to industries that are competent organized system Management in compliance with all technological, economic and organizational requirements characteristic of the production of developed countries. Both Russian VEKA factory have this certificate.

If the profile is wider, then it is more reliable and warmer?

Profile width is one of its main characteristics. Many window manufacturers promise a couple of extra millimeters to the profile width in their advertising campaigns, but are there any benefit from them?

The market most often meet the following proposals:

1. classic profile 58 mm;
2. profile 70 mm with an enlarged mounting width;
3. profile of VEKA AlphaLine 90 mm.

The width of 58 mm is due to the "classic of the genre" - wooden frames, on the shift that windows came from plastic. To date, the EUROLINE 58 mm profile allows you to produce modern warm windows that satisfy the requirements of most buyers in different climatic zones. Given that proper production and installation, this is the best profile for windows in any room.

A 70 mm wide profile is a proposal that appeared in the 80s of the last century. Having higher heat-saving sound-proofing characteristics, this profile especially loved to Russian consumers. In the VEKA Profile Commodity Group, 70 mm width have Softline, SwingLine and Proline.

A 90 mm wide profile is a premium product that appeared about 5 years ago. VEKA ALPHALINE profile allows you to use double-glazed windows with a thickness of up to 50 mm and is currently an unrivaled leader among window profiles with increased energy-saving characteristics.

Note!

The choice of profile width largely depends on the installation site (window in the office, a tambour door, entrance door In the store, windows in a country house) and climate.

Now another new product has appeared on the market - the profile of Softline 82. An innovative multi-chamber system, an elegant style and the ability to choose from more than 40 modifications guarantee the needs of the most demanding client. The SoftLine 82 system provides the best insulating characteristics, fully compatible with 70 mm profiles and can be installed in any homes.

Number of cameras

The second feature of the window is the number of cameras in the profile. In the standard three of them. The first is to remove condensate, the second - to accommodate the reinforcing metal liner, and the third is to fix the parts of the fittings and create an additional air layer for the best tightness of the window. The number of chambers depends on the profile width. So, the 58-mm profile may have a maximum of three cameras, but a 70 mm profile is desirable, four. For a 90 mm profile, 6 cameras are.

Three and six chamber profile systems

Increasing the number of chambers with the same profile width, insignificantly changes the window characteristics. To increase the heat-saving characteristics, a wider profile is needed, and no longer the number of partitions in it.

Full package

Another important point is a glass. The number of glasses in the window affects its characteristics and cost. Double double glazed windows are the most common, but you can also order windows with single glazing or triple double glazing.

"Triple" windows are warmer. However, they will weigh more and require high-quality installation and stable design. Single glass is the coldest. It can be used for glazing unheated balconies, as well as summer houses. Double double glazing is optimal in technical characteristics, and allows you to keep comfort in the room in all year round.

Profile class

There are two classes of metal-plastic profiles. The first, class A, with a thickened outer wall, is certified by the RAL system as an optimal profile for windows, doors and frame glazing.

Helpful advice!

The second, class B is a lightweight profile with a thinner outer wall, the so-called "object" profile. It has a slightly lower cost, but does not guarantee the conservation of the window characteristics throughout its operation.

Windows from the "object" profile, as an economy option, can offer absolutely all manufacturers, but you must remember what a window can have more weak corner connections, worse formulability, lower energy-saving characteristics, the risk of premature accessories, less service life.

conclusions

Summing up the arguments on the topic of choosing a profile for a metal-plastic window, we emphasize:

• The availability of certificates confirms quality.
• By mounting width, all profiles are divided into two main classes: 58, 64 mm and 70 -76 mm. Inside the class heat engineering The same. A 68 mm wide profile and a 72 mm wide profile do not differ from each other.
• The number of cameras affects the quality of the window only if the profile refers to different classes In width.
• The most common is double double glazing.
• Class A profile is a leader in reliability and quality.

Selecting the windows, you will hear the necessary information and screen advertising. The quality of your windows depends on your choice. Do not spare time to make a choice right!

What plastic windows PVC are better - 2 chamber, 3 chamber or 5 chamber?

Often we are confronted with confusion when discussing plastic windows, confuse cameras in a double-glazed window and cameras in the profile, I hope that this article will help you deal with cameras in modern plastic windows.

In his article 3 chamber and 5 chamber profile - what is the difference? We already understood what the 3 and 5 chamber profile differ, now let's see which profiles are better.

Here the more, the better - many cameras do not happen.

Plastic windows consist of profile and glass and accessories.

The double-glazed glass can be single-chamber (2 glasses and one air chamber between them) and 2 chain (three glasses and two air chambers between them), also the profile can be 3 chamber and 5 chain (there are profile systems with large The number of air chambers).

2 chamber windows are almost 1.5 times warmer than one-sample. The heat transfer resistance of the glass unit from 3 glasses is 0.42 sq. M C / W, and for 2 glasses - 0.33 sq. M C / W. Many mistakenly believe that the additional third glass is made exclusively for noise insulation.

In fact, in the first head, the third glass is put for heat saving and only then for additional noise insulation.

The same is the case with the profile. Not only is the 5-chamber profile warmer, he is also tougher, he does not have a cold bridge in the area of \u200b\u200bthe loop (in the 3 chamber profile in these places there is often freezing during the winter).

But the most important thing is that the 5-chamber profile has a thickness of 70 mm and the double-glazed windows can be installed with a thickness of up to 44 mm, whereas in the 3-chamber not more than 38 mm, and this is additional thermal insulation and energy saving.

What a glass pump and some profile choose.

If the window goes to the balcony / loggia that are glazed or you plan to glazed them later, then in this case you should not overpay and it is worth choosing a window with single-chamber glass and 3rd chamber profileIn all other cases, 2 chamber glass windows and a 5-chamber profile (or more cameras) will be preferable.

So you decided to change your old windows on new plastic. You bypassed and called a huge number of window companies, but there were only more questions. You do not see what is different window company From the other and how the plastic windows are distinguished by one company, from the windows offered by another company, and if there is no difference, then why pay more?

And here you make the most common mistake - you start looking for a company that can offer a minimum price for plastic windows.

You should not hurry, now we will figure out and what the windows are different and that the window companies are trying to hide from you.

PROFILE

When it comes to the PVC window, the most common question is specified - "What profile are your windows?". At the moment, there are more than 40 manufacturers of profiles on the market and each manufacturer in its arsenal has a large number of Different profile lines.

All European manufacturers offer a quality product (Kbe, Gealan, Veka, Rehau, Schuco, etc.) - a guarantee for such a profile for at least 40 years, such a profile does not crack and does not yellow. Somewhat other picture with Turkish and Chinese profile systems. Without going into unnecessary details, I will say that the European manufacturer is preferable, and they simply forget about the rest, especially since there is practically no difference in price.

As we have already spoken, each manufacturer offers not one, but a whole range of profiles. Various profile systems differ from each other thick, the number of seal contours, design. As for the design, here as they say and color, the number of sealing contours does not affect the purge and overpay for it is definitely not worth it, but the thickness of the profile is the factor not unavailable.

For middle strip The recommended profile has a thickness of 58-60 mm, but in practice when low temperatures In places of fastening the loops, the bridge of cold occurs and freezing and formation of land. We recommend the profile from 68 to 84 mm and the double-glazed windows in such a profile can be installed thoroughly. The difference with a thinner profile is insignificant, but the rigidity and thermal surgery of such windows is much higher.

Many manufacturers produce, the so-called, object profile, for installation in non-residential premises, externally such a profile is no different from the usual, but the thickness of the walls of such a profile is significantly thinner and plastic used in such profiles is plastic recycling plastic. A lot of companies wanting to give the lowest price in the market, sell such windows under the guise of ordinary counting on the client's uneducation. But it is not about us.

It is not easy to identify such a profile: the protective film often does not have any inscriptions at all, or there is a word: an object, Object, Engine, tender or something similar. Be extremely attentive - this profile categorically cannot be used in residential premises, it does not have the required rigidity, thermal conductivity and can highlight an unpleasant odor.

Waterpressure Planck

The overwhelming majority of companies do not install waterfront planks, mandatory installation. Water-grades protect you from water from getting during the rain in ventilation mode (in folding mode)

There is a chance that such a company could save on something that it turns out only during the operation of the window.

REINFORCEMENT

Plastic windows correctly called metalplastic, since inside the plastic profile reinforced with metal. The metal gives strength and stiffness of the structure, but reinforcement is inside the profile and hidden from the eye of the consumer than the unscrupulous sellers enjoy. They simply do not reign their windows. Such windows are very often installed in new buildings.

Take the magnet, and the frame and the windows sash must be reinforced with the metal, which is easy to check the magnet. If you failed to find metal using a magnet, then let such a window look for another owner.

ASSEMBLY

In order to collect a high-quality plastic window, it takes good (read expensive) equipment, special stands for adjusting accessories and check welds and qualified wizards. This can afford only a major manufacturer.

Otherwise, as a result, not the correct geometry of the window, a bad fit, blown, the quick access of the fittings. The quality of the assembly is very difficult to determine the eye, you need to do measurements and so on, so just ask the seller who is the manufacturer. If this is a small local company in a small town, then you cannot be any quality and speech.

Furnitura

Furnitura is very important component Your window, the quality of fittings determines the service life of the window and how comfortable it is comfortable. Here the leaders are the Germans. These are Roto, Siegenia-Aubi, Maco, all the rest avoided. But also establishing high-quality fittings have a lot of ways to save.

Error blocking blocker

I miss the installation! If you opened the window, and then transferred the handle in the folding mode and the window was hung on the same bottom loop - it means that the block is not installed. This window will not serve for a long time, and may cause harm to health. We witnessed when the sash simply fell out, almost killing a small child.

Be sure to purchase and after the window you already mounted, check the presence in the block of the block.

Response Planck

The response plate is placed on the inner perimeter of the frame and is responsible for the density of the constructor. After all, we chose plastic windows for their tightness and energy-saving properties.
The number of response planks depends on the size of the window, but they cannot be less than 4.

Note!

We know the companies that put 2 response slats on the window, nullify all the advantages of plastic windows. In this case, the window will blow, and you can form a land on glass and windowsill.

Often, cheap plastic handles are installed on the windows that quickly fail. Good handles are produced by Maco and Roto companies, which should be written on the handle. These handles are made of aluminum and plastic covered, from cheap plastic differ in high weight and for a long time operation.

Sucks

High-quality slopes are made of insulated sandwich panels. On such slopes, fungus is not formed, they are warm, tough and do not have joints.

The junctions between the slopes should be linked with liquid plastic, and not silicone, which in the month black and fall off. The jokes on the slopes are flashed with liquid plastic.

Liquid plastic has a tight structure that the PVC from which your windows are made, which means that the liquid plastic will not differ in color, the fungus does not form on it and it does not crack. It has the same expansion coefficient.

Many companies continue to use not high-quality cold wall panels, making the gap sealant. As a result - cold slopes, fungus, silicone must be changed every half a year, Silicone darkens and looks so much worse.

INSTALLATION

Be sure to use vapor-permeable psyl tape (pre-compressed sealing tape). The tape is needed to protect the foam from the sun and remove moisture out of foam.

But cops requires protection against ultraviolet, for which naschelniks are used or external slopes.

We told only some ways to save. The rest are either less significant, or to identify them without a specialist is not possible.

Both are attentive when choosing plastic windows.

In the choice of profile for the glass package, every little thing is important. It would seem that all plastic windows are the same. However, it is discovered that the service life of approximately the same products is different, and the qualitative characteristics of some often leave much to be desired. Therefore, it is necessary to approach the choice of profile with full responsibility.

Structure

PVC profile is a plastic frame for the glass package. Despite the seeming simplicity, this design is difficult. In the transverse section of the profile, a variety of aircases can be seen. The maintenance of heat is ensured. Than them are more better level Heat shields.

For stiffness and reliability, the metal frame is inserted into the profile. This process in production is called reinforcement. Due to reinforcement, the profile becomes stronger, eliminates the possibility of its deformation and resistance to the change in the structure under the influence of negative environmental factors (for example, rain, impetuous wind and frost). Profile material is polyvinyl chloride.

Regardless of the type of profile metal stripes inside it are an important factorTo which you need to pay attention to when ordering. Precisely because of them the profile is called metal-plastic

Longitudinal chambers in frame structures are responsible not only for the preservation of heat. They are ramp amplifiers. External sections are discharged condensate, which can occur inside the cavities due to the temperature difference in the room and on the street.

At the bottom of the design they have a connection to the atmosphere. Due to this drop, when they appear on the street. The presence of such holes does not affect the level of heat in the room: heat in the room does not decrease. Externally, such elements do not spoil the aesthetic type of windows, as they are in most cases closed with plugs or simply are not visible against the background of the entire design. The presence of data holes speaks about a high-quality window. It will be more durable compared to the modification without them.

Features

Plastic profile (PVC) is the basis of windows. It is from him that the reliability and durability of the whole design depends. Sashes and accessories are made from this material, glass windows are installed in it. It depends on the main characteristics of the window structure, including the level of noise insulation, as well as tightness. It also affects the preservation of heat indoors.

Metal-plastic profile is a sash and a frame with a different number of cameras (up to 8). The most popular products for buyers are options for 2-3 compartments. Fundamental factor technical characteristics are the size of the windows. Thus, the species of panoramic type are characterized by smaller noise and thermal insulation properties in comparison with the analogues of smaller sizes.

Due to the increase in the conservation of heat in such structures during installation, you have to resort to the mounting foam when the cameras are filling. In addition, the designs may have a fiberglass coating with rigidity ribs. One of the meaningful characteristics during installation are the thickness of the overlap and the assembly width. They are responsible for the rigidity of the profile design and the reliability of the sash themselves.

A modern plastic profile for windows is different from the analogues of its appearance. Today, its qualitative characteristics are quite high, as well as decorative features. The technological and functional frames have long fastened analogs of wood, making glazing reliable and ergonomic. Unlike wood, polyvinyl chloride does not give a shrinkage. Such windows will not be deformed during operation.

PVC windows can be installed in buildings of different types. They can replace wooden frames in homes, the active shrinkage phase of which is already over. At the same time, tenants will be protected not only from cold and noise, but also from dust. Typically, such structures pull any, even the boring design of the premises and harmoniously look in the architectural context of the buildings of different types. Plastic capabilities to mimic any texture allow you to use such frames in any design style.

The profile surface can be matte, glossy and even three-dimensional.Color solutions of such products today are diverse and can satisfy every taste. For example, you can choose a profile under the expensive variety of wood (wenge), show imitation of the aged tree.

When more luxurious solutions are needed, they choose plastic under stone and even the skin of reptiles. The drawing depends on the client's preferences: trademarks are often ready to fulfill the customer's individual order.

Characteristics

Among the main characteristics of such a profile can be noted:

• resistance to oxidation, exposure to high temperature;
• resistance to moisture and water;
• security for the health of households;
• aesthetic appeal;
• low thermal conductivity coefficient;
• variability of forms of structures;
• fitting in any historical design of architecture;
• different degree of complexity of designs and mechanisms of windows;
• rich color palette.

In the care, such a profile is easier for wood analog. It does not need to cover the veil or other paint over time. To cleanse the surface in most cases it is enough to use a damp cloth or a semi-dry sponge. However, in the case of significant mechanical damage, it may form scratches, which will not be able to hide in any way. This is the main disadvantage of such structures.

Options with different number of cameras differ operational characteristics. For this reason, their choice is often based on the climatic conditions of the region. If winter in it is cold and windy, the cameras are trying to choose with a large number of compartments. At the same time give preference to a greater glass thickness.

The profile is environmentally friendly. It is far from harmful plastic, which produced in production earlier. Such a frame with flaps will not distinguish toxic substances during the operation of the window. When choosing, it is important to pay attention to the number of cameras. If the glazing is cold, there must be no less than 3. Such profiles can be used for balconies, loggias and industrial facilities. When you plan to glazed heated buildings (school, house, apartment, restaurant), the number of necessary cameras increases to 5.

Views

In addition to polyvinyl chloride, in the design of the PVC profile, aluminum or steel are used for windows. Metal is used in horizontal and vertical elements. . Profile production is subject to the requirements of GOST 30673-99 in our country and EN 12608 SR in Europe.

The profile of the first group is the best option and is intended for buildings of residential type. It is characterized by a thickness of the outer walls of about 2.8 mm and more internal - from 2.5 mm. This variety is more resistant to random mechanical damage. The analogue of the category "B" is characterized by a smaller wall thickness.

The inner walls have a thickness of 2 mm, while the outer thinner is 1/3 mm. It seems to be a little, but that is why such options are less resistant to mechanical loads. They can be used for the premises of the heated and unheated species. The profile with marking "C" is characterized by smaller indicators of the thickness of both walls. In the language of experts, it is called objects.

In contrast to the two previous options, it does not have a normalized thickness (it is clearly less than categories "A" and "B"). The disadvantage itself is the structure of this type: it does not have opening flaps. The monolith of such windows makes them less demanded from buyers. Apply these varieties in the premises of the unheated type.

In essence, all existing varieties Plastic profile for windows can be divided into 3 types:

• economy;
• standard;
• suite.

Window plastic profile is the main and stupid. On store shelves today you can buy a profile:

• connective;
• coaching;
• reinforcing;
• expansion;
• P- and F-shaped.

These are tubular structures with blocks inside, of which the window frame is folded. Cameras are different in shape and volume. Some of them are not connected with each other or with an external environment. They are sealed, while others serve for ventilation. Depending on the size, filled with air and the number of cameras, such profiles have a different purpose. Some of them are used for industrial premises, others can be used for residential buildings.

A g-shaped species is characterized by the gain of two walls of the profile. P-shaped type It is the reinforcement of three walls. In a closed form, all parts are hardened. In this case, the choice of profile depends on the number of glasses in the design. From this, the chambers in the frames directly depend.

Varieties are distinguished by the degree of frost resistance. Thus, options for frost-resistant design with the mark "M" are calculated at temperatures up to -50 degrees C (check load). Analogs of normal performance are suitable for regions with minus temperature Up to -20-40 degrees C. The difference depends on the type of base material used.

Dimensions

Profile parameters are determined by its width and thickness. In this regard, manufacturers try to stick to standard values. A common frame rate may have dimensions of 58x63x43 mm. The sash dimensions are 58x77x57 mm, the imposed is 58x87x47 mm.

When the profile accommodates 6 cameras, its thickness can be 85-90 mm. At 70 mm, it usually has up to 5 cameras. In the first case, the profile is thick and fits not for each window opening. 70 mm is considered the best option if up to 5 cameras.

The thickness of the facial wall of the class "A" is average of 3 mm. Analogs of the category "in" this indicator is reduced by half a millionth. Not the facial side of the classes "A" and "B" thinner by 0.5 mm each from the values \u200b\u200bof the facial wall. In the category "C" manufacturers do not indicate data. The assembly width of the profile in some varieties can be 104, 110 and 130 mm.

How to choose?

In the current market of such materials, the PVC profile is presented in a wide range. Buyer is easy to confuse. However, to do right choice It is quite possible, not being a specialist in the field of construction and installation. To begin with, it is worth paying attention to the material itself. The appearance of the plastic can tell a lot about his quality.

When there is no decorative laminated film on the profile (imitation of the desired texture), just one attentive look. Qualitative material Differs in the monolithium of the structure. It should not have roughness, inhomogeneities. Any stains are excluded, irregularism. A noticeable graininess will indicate a fake product.

Buying such a PVC profile is impossible. Typically, such samples may occur from one-day firms. Such companies offer installation of windows from their material. It is made from cheap and harmful raw materials. Therefore, it is impossible to expect any qualitative characteristics from such a profile.

Yes, and about the manufacturer before buying components you need to know. For this you can find out more about the company's reputation based on feedback.

It is important to understand that profiles have some differences between themselves. They are cut on special machines under specific dimensions constructions. This applies not only to the flaps, but also racks and cross. Therefore, when buying, you need to purchase the entire set at one brand. Otherwise, you can not count on an impeccable docking of the elements, whether it is a connection with special welding or mechanical hardware.

Cameras

Before buying it is important to ask the number of cameras. Usually, the quality products of the famous trademarks are more than 5. This is enough, while 7 cavities will be surprised. In this case, it is impossible to forget that not the number of cameras, and the wall thickness is more important. After all, they will be responsible for the level of heat to a greater extent.

In addition to options with air chambers, a PVC profile can be found on the market today, in which emptiness is not filled with air, but to heat insulator. This is predominantly material based on foam (polystyrene foam) or fiberglass. Such a profile appeared on the market relatively recently.

However, experts believe that it is more effective regarding the conservation of heat. The disadvantage is the cost of modification, which is noticeably above the traditional options.

Width

Since the choice of profile provides comprehensive analysis, it is worth paying attention to the PVC-profile width. It is often called the assembly depth in the language of experts. In the standard profile, its indicator usually varies in the range of 50-80 mm. It depends on the number of cameras inside the element. Usually with a smaller width, the design has no more than 3 cavities. When the width exceeds 70 mm, their number increases from 4 to 5.

However, it is impossible to assume that the wider the profile, the more cameras in it. This is not always true, because depending on the design features, the profile can be wide (for example, up to 9 cm), but with a minimum amount of cavities. Such options may differ excellent heat insulating characteristics, since the value in this case has a stock of air and the dimensions of the cavities themselves.

In some cases, the mounting depth can be 10 cm. Such options overlap the window opening, so often do not need to install external slopes. Them a distinctive feature is a cross section in the form of a trapezium. These windows are called "Dutch", "Danish". They are definitely better than the usual analogs, although their installation is not every pocket.

Planting place

It is impossible to buy a plastic profile, not knowing the depth of planting a glass package. It is this factor that is responsible for the type of glass package, its quality, as well as heat-shielding properties. A good profile frame is a design where the glass can be found from the front slice at least 1.5 cm, overlapping the folding profile.

If you plan to mount the frame to a depth of 5-7 cm, the landing place for the installation of glass should be 1.8 cm. Few people pay attention to this aspect when buying a profile. However, if it is ignored and relying solely on the width of the profile and the number of cavities in it, you can not be surprised in the future, that the double-glazed windows stuff or freezes.

In addition, it is worth paying attention to 4 factors:

• Linear expansion.It must be minimal so that the emptiness is not formed during installation. The higher the lower the window frame size.
• The coefficient of elasticity.The presence of steel is a mandatory criterion for choosing a profile. At the same time, the thickness of the internal walls (rigidity rigs) is important.
• Resistance to the temperature differenceand UV rays. The composition of polyvinyl chloride should be stabilizers that allow you to maintain inertia to loss of color and structure.
• Sealer.Of thermoplastic, thermopolymer, silicone and rubber, it is worth providing preference to silicone products. It is racks to abrasion, inerton to the temperature difference.

Each profile is provided with a certificate. It indicates the data on the type of product and its place of production.

Decor

White color Ram today is considered old-fashioned. He replaces profiles with a laminated film that can imitate any texture. These may be neutral options (gray, black), as well as tone under the wood. Of course, such a solution for the window design will cost more, but by paying 15-20% more, the buyer can equip its home, taking into account the choice of a specific design.

If the choice is made in favor of the colored frame, the shade is selected with the interior and exterior. The frame should look beautiful outside and inside. You can start from the color of the existing furniture, doors. The color profile may have a sick-related shade, but the different color of the color is undesirable. However, the choice of color profile has its own nuances.

Light tones will not be warm under the sun as, say, dark stony or wood brown shades. This means that when choosing a color profile, the presence of metal in the frame is necessarily regardless of the size and shape of the frame. In addition to lamination, manufacturers are stained with a PVC profile by acrylic spraying, complement it with metal overlays or wood. The decorative reception is the form of elements that today is more encouraged and may have a complex relief.

To date, you can order a window plastic profile under oak, alder, fir, mahogany, malachite, marble. For more creative design In the palette of shades there is yellow, turquoise, blue and wine shades. Due to lamination, you can decorate the frame frame with the effects effect. If you wish, you can choose and coatings with a three-dimensional effect creating a feeling of volume and relief.

Manufacturers and reviews

To date, many companies are ready to offer a PVC profile buyer for windows. Several companies included in the rating of the high assessment of professional masters:

• Rehau;
• Veka;
• Proplex.

Their products are characterized by high performance and meets the established standards of European standards. Such frames do not arouse the complaints of professional masters, they are easy to install and are not deformed during operation. According to customer reviews, these products are characterized by a high cost. However, the goods are worth it, since the profiles of these brands are durable, the stands for mechanical impacts and are not destroyed over time.

Rehau.

German manufacturer Profile with a wide range of products. The brand is focused on all sectors of society, the production of economy-class products, standard and elite. Options are designed for different climatic conditions. The number of cameras in the profile varies from 3 to 6. In this case, the mounting depth has a range from 6 to 8.5 cm. The products are characterized by a high level of noise and thermal insulation. They are suitable for gray seals.

Veka.

Profile russian productionmanufactured by German technology. Corresponds to the class "A", intended for use in any regions of Russia with different climatic background. Today is presented 8. different species with different range of mounting depth (58-90 mm). The number of air chambers inside the profile is from 3 to 6. Equipped with durable metal carcasy, it looks stylish, beautiful and modern.

From the article you will learn:

Currently on the Russian window of window products, despite the ever-increasing number of sales of wooden and aluminum structures, leadership is saved outside the windows of plastic. This contributes to the lot of advantages that possess PVC products. The main ones are definitely excellent heat and noise insulation, a long service life, the possibility of using additional accessoriesboosting the functionality of the window ( mosquito net, thermometer, etc.), as well as a magnificent appearance of coupled with an affordable price.

As you know, the basis of plastic windows is a profile. In the entire light-cutting design, it accounts for about 10% of the entire area of \u200b\u200bthe product. The remaining 90% takes windshirt.

It is no secret that all PVC profiles coming in the composition of the same windows are the same. To pick up the optimal option that fully responded to requests in appearance, the level of sound and heat insulation, as well as the price, the buyer must have an idea of \u200b\u200beach element of the window, to be able to freely operate with technical terms associated with each component.

In this article, we will consider in detail the highlights that you should pay attention to when choosing a window profile, we describe its design, explain the values \u200b\u200bof the main technical terms.

How many cameras should be at the plastic window.

An image is clipable.

When considering the characteristics of the Svetopropus-PVC Design Model in the model, special attention should be paid to three moments:

• profile;

Most significant characteristic Profile is his camera, that is, from how many cameras it consists. Their number directly determines how well the plastic profile retains heat.

Camera profile. For residents of regions, where most of the year reigns cool weather conditions, the most preferred option is a three-chamber profile of the window. Three cameras reliably protect the design from purge, and therefore, they perfectly hold warm in the room. In addition, they are built into them with a metal frame designed to enhance plastic sidewalls. The three-chamber profile of the plastic window, as a rule, has a width of 5.8 cm.

Profile with four or five cameras. Products, which contain four, or intended, first of all, for operation in the regions of the country in which the summer season is not long, but temperature conditions Obviously leave to desire the best. The protection provided by the profile with such an increased number of chambers is coping with even the lowest temperatures (30 C and below). Therefore, indoors, glazed windows with a multi-chamber profile, in any weather will be warm and cozy. It is worth noting that the application of such windows in the warm regions of such windows is justified due to: soft weather conditions; Prices that significantly exceed the value of their three-chamber "counterparts".

Single-chamber and two-chamber profiles. It is used mainly for glazing apartments and private houses located in the southern part of Russia. The lack of a structure that does not allow them at low temperatures to cope with the retention of heat with interest compensated for by their price - it is significantly lower than the cost of plastic windows models, the profile of which in its composition has a greater number of cameras.

Constructive elements of a plastic profile. Click on the mouse increases the image.

As a result. If you need the maximum cold protection, stop your choice on models of plastic windows from 4 or with a 5-chamber profile. In the absence of need to maximize heat saving in a glazed room, for example, in the southern regions of the country, where hot weather prevails, one or two-chamber PVC designs should be selected.

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

Criteria for selecting a profile, depending on its thickness.

Profile in the context. Click to enlarge.

An important characteristic of PVC profile is its thickness. It depends first of all, on the number of cameras and, indirectly talks about the ability to maintain heat by the window: the wider profile Topics, as a rule, it is warmer.

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

58 mm. Profile, 5.8 cm wide is the most popular window designs in the Russian market. Against the background of the rest, more "thick fellow", is highlighted by a small price with quite a balanced characteristics. As they say - cheap and angry. However, if the buyer pursues the goal to glazing the window opening without claims for superfold, then the model of the plastic window with a 58-mm profile, fully satisfy its desire.

70 mm. The profile width of 7.0 cm allows the product to arrange in it from 3 to 5 cameras. Such thickness is more than enough to ensure a glazed room of the proper level of heat and sound insulation.

90 mm. The most wide range of the profile for PVC windows that best copes with the issue of retention in the apartment. Accommodates up to 6 cameras. The main disadvantage of such a 9.0 cm solution is its price, which is significantly higher than other similar products having a smaller thickness.

There are also structures, the profile width of which is rather impressive 110-130 mm! Such windows are also called "Danish" or "Dutch". They, so to speak, are designed for an amateur.

Double-glazed windows.

The glass, as already mentioned above, takes about 90% of the area of \u200b\u200bthe entire window. To date, there are three types of double-glazed windows that differ in the number of glass installed in them:

• One glass. Not suitable for installation in a residential fund due to the presence of insufficient characteristics in such a glass package. The main flaws in the design of the single glass package are poorly preserved heat, as well as in the absence of protection from. With the onset of the cold season, such minuses can contribute to the salinage of the room, as well as the formation on the glasses of the impressive layer of land.
• Double-decker design. Represents the most optimal solution for installation in the apartment or a private house Due to the good price relationship and characteristics. It is practically eliminated so-called, and heat in a glazed room is saved much better than when using the glass package, which contains only one glass.
• The solution includes three glasses. With the installed triple glass, it is possible to achieve not only the greatest savings of heat, but also the maximum security of the apartment from penetration on its territory from the street of all sorts of noise. Triple glazing has only two drawbacks - this is a high cost and.

From the foregoing information it follows that for most buyers the best option will be the acquisition of double-glazed windows, which consist of three glasses. With a shortage of funds, you can stop your choice and on a double double glazing with the best price / quality ratio.

Selection of profile depending on the manufacturer and class.

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

Important! Most fully this issue Illuminated in our previous materials entitled "" and "".

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

Profile class A. can be used as in residential buildingsand geometrically complex facade structures. It has a long service life, has a thickness of the walls of at least 3 mm.

Profile class A. Click to enlarge.

Due to the constructive features, class b profile is customary to the budget decision. The main factor affecting the price is the presence of a thin wall product. It is due to savings on the thickness of the material used for the camera wall, manufacturers of PVC profiles class B. They got the opportunity to keep prices for their products extremely low. The price of the price, however, should be remembered that such a marketing move may not affect the duration of the plastic window, equipped with such a profile - the system life will be significantly less.

Summing up the result of all the above, I would like to pay attention to a completely obvious fact: all elements of the plastic window are interrelated. Making a choice in favor of a warm glass, you should get acquainted and buying a warm window profile. Otherwise, the design, due to the essential differences in the technical characteristics, may be unbalanced.

Select profiles for plastic structuresoffered by various companies is almost infinite. But to choose a product that will fully comply with your requests, you need to keep in mind a few features. It is about the criteria for choosing a profile I will tell.

Construction and types of profiles

The profile system is a kind of "window skeleton". Window profiles are made from PVC (polyvinyl chloride) by extrusion - extrusion through a special form. After that, they are enhanced by the inner reinforcement, cut into parts of the desired length and then weld into the frame or sash.

PVC is not the only material for the manufacture of such parts. Where the strength is needed at minimal mass, metal frames are used. The wooden profile of glued bar is also used - but the high price limits its popularity in the market.

The window profiles on the market are very much, but all of them can be divided into two groups: basic and additional.

From the main profiles, parts of the window are made - frames, sash and their combinations.

Illustration	Profile type
	Frame Profile for windows from which the frame is made. Is different rectangular shape With one protrusion - from the outlook. Smooth surfaces provide durable fixation at the edges of the opening, and the sash or double-glazed glass is pressed.
	Claw In the section, it resembles the letter Z. One of the protrusions provides clamping to the frame of the frame, the second - fixation of the double-glazing and other filling.
	Imposte Used to connect two frames when creating a double design. It has a T-shaped form: from both sides to the crossages pressed the naplots of the frames.

In the production and installation of plastic windows also use additional profiles:

1. Stand.
2. Connecting.
3. Expansion, etc.

What do you need to know?

Criterion 1. Cameras and thickness

Any instruction on the choice of PVC profile for the manufacture of the window begins with determining the optimal number of cameras. Cameras are cavities inside the product that provide heat insulation and give structures rigidity at the expense of their walls.

Here you need to keep in mind:

1. Correct counting. Cameras are considered only horizontally: vertical division by partitions is performed only to increase strength.
2. The thickness of the inner walls.This is not so important the number of cameras as their quality: the thickness of the partition, the better.

1. Cameras are an indirect criterion. Characteristics and types of profiles with the same number of cameras may differ, and very much. Therefore, it is considered, but we do not forget about other parameters.

In general, you can focus on the indicators in the table:

Criterion 2. Installation depth and thickness of the outer wall

When choosing products, the thickness of the profile is also important (the term "assembly width / depth" is often used) and its wall thickness:

1. The optimal width is from 65 mm and more. Cheap three-chamber profiles are made of 55 mm wide, which does not allow to ensure good thermal insulation. So if it is important to minimize the loss of heat - we take the model sewing.
2. Front wall - not less than 3 mm. This value is set by the standard for class A profiles (can be used in the glazing of residential premises according to GOST 30673-99 "Polyvinyl chloride profiles for window and door blocks"). If the thickness is in the range of 2.5-2.9 mm, then we are talking about class V.

The windows from the profile of the C-class can also be installed in the apartment, but over time it will wear out, losing its and without that low functional characteristics.

Criterion 3. Color profile

If we talk about color, then plastic windows are:

• white;
• painted in mass;
• laminated.

And if the quality of lamination and painting can be estimated visually, then with white color there are a number of nuances:

1. Ideal white painting PVC gives titanium oxide. Such material does not turn yellow over time and does not adsorb substances from the air. Minus - windows from a profile with titanium pigmentation cost more.
2. For the purpose of economy Some manufacturers replace a piece of titanium oxide (or even all) chalk. As a result, after two or three years, the surface of the window turns yellow due to the absorption of various substances from the air.

The choice is obvious: For the manufacture of PVC windows you need to take only material painted using titanium pigments.

Criterion 4. Internal reinforcement

Different types of windows are experiencing different operational loads. But in any case, PVC will not cope with them in itself, because the window system is enhanced by internal reinforcement.

Reinforcing inserts are made of galvanized steel. When choosing a design, this indicator needs to pay attention to such parameters:

1. Configuration. The greater the rebar ribs at the reberes, the better. For frames and flaps, a closed (square) armor is preferable. If you need to save, and the loads are allowed, then we choose P- or M-shaped fittings.
2. Metal thickness. From this, the rigidity of the window structure directly depends. The standard thickness was previously considered 1.5 mm, now at mass production using main metal 1.2 mm. For balcony doors and big windows I would recommend reinforcement of at least 1.8-2 mm.

1. Accommodation and fixation. The metal insert should be located in the center of the plastic part of the design and securely fixed with self-drawers. Ideally, the Amrier at the corners need to be combined with special adapters - then the deformation of the frame or sash will be excluded.

Conclusion

After examining the features of window PVC profiles, and deraiding which one for what is responsible for, you will seriously facilitate my life when choosing plastic windows.
