Useful tips: which windows are better to put in an apartment - reviews and ratings. Which window profile is better to choose PVC windows which profile is better

The companies Rehau and Proplex have a good reputation in the modern market of plastic windows in the middle price segment, but which is better - the indisputable and respectable German quality, time-tested, or Russian ergonomics according to Austrian technologies - it is difficult for an ordinary buyer to understand. Judging by the reviews on the network, the products of both companies are worthy of attention. To understand all the intricacies of choice in order to wisely spend savings and get the warmest, quiet, strong, durable, safe plastic windows, a detailed comparison of their designs will help.

Rehau and Proplex product range

To get a more complete picture of the strengths, weaknesses of the products of Proplex and Rehau, it is worth starting with a brief historical background and acquaintance with their range.

Rehau is a world famous German concern operating in Germany since 1948, which produced the first profile for pvc windows in 1959. To date, its assortment includes more than 10 types, the most popular of them are as follows:

1. Geneo – the latest development, a six-chamber innovation, reinforced in mass (RAU-FIPRO technology) with almost half-lightweight, but still robust construction, allowing the use of glass units up to 54 mm. At 86mm depth, the highest heat retention factor is 1.05 and sound insulation is 47dB.
2. Intelio – The 80-mm novelty of 2017, has six chambers, with a glass unit up to 51 mm, perfectly retains heat (0.95 m2 ° C / W), and also protects against noise (47 dB).
3. Brillant-Design – an exclusive curly five-chamber design for the embodiment of any design ideas (70 mm), together with a glass unit up to 44 mm, excellently conserving heat (0.81 m2 ° C / W), as well as filtering noise (36 dB).
4. Grazio- an elegant five-chamber representative among 70-mm structures with a double-glazed window up to 41 mm, attracting not only with its aesthetics, but also with high performance - heat transfer resistance - 0.85, sound insulation - 45 dB.
5. Delight-Design - a five-chamber design for dark rooms (70 mm), transmits 10-15% more light, with a glass unit up to 41 mm, it is excellent for frosty areas (0.80 m2 ° C / W), sound insulation 32 dB.

7. Blitz - a three-chamber budget version with an elegant shape and an extended range of colors. The depth of 60 mm allows the use of a glass unit up to 32 mm, the heat transfer resistance is 0.64, the sound insulation is 32 dB.

Proplex profiles

The Russian company Proplex is one of the five largest manufacturers of profiles for plastic windows in the country. Its plant is located in the Moscow region and has been operating since 1999. The production is carried out using unique Austrian technologies. Today Proplex's offers are as follows:

• OUTLINE - A 42-mm two-chamber profile from Proplex, which has a not too high coefficient of resistance to heat transfer of 0.405, but which, in combination with a glass unit up to 22 mm, is quite enough for the second line of glazing (balconies, loggias, verandas, terraces) or non-heated non-residential premises.
• Basis - affordable, reliable 58 mm three-chamber design with decent heat-saving properties (0.64 m2 ° C / W). It can be used with a glass unit up to 32 mm for glazing office or industrial premises, as well as residential buildings located in warm areas or operated mainly in the summer (summer cottages). Can be combined with anti-burglar fittings.
• Optima - 58-mm budget three-chamber version, which has basic safety, but at the same time warmer (0.70 m2 ° C / W) due to the internal structural features (special arrangement of chambers and reinforcing liner). Designed for use with a double-glazed window up to 34 mm for glazing living quarters, withstands significant temperature fluctuations.
• Comfort - 70mm energy efficient four-chamber design, suitable for insulating glass units up to 42mm, with a heat loss resistance coefficient of 0.80. An excellent option for residential premises without regional restrictions.
• Hit - a popular five-chamber design (70 mm) with an ideal price-performance ratio. In combination with a glass unit up to 42 mm, it perfectly retains heat in the room (0.81 m2 ° C / W) even when temperatures drop to -60 degrees.
• Premium - a five-chamber premium version with a coefficient of resistance to heat loss of 0.82 at 70 mm. It can be used with a glass unit up to 42 mm, suitable for glazing buildings in harsh climatic conditions, as well as in areas of high noise.

Benefits of Rehau and Proplex

The range of both competitors is impressive. In order to decide: Proplex or Rehau, it is necessary to analyze the advantages that their products have.

Rehau benefits

Comparison of Rehau's offers with analogs of its main competitors made it possible to identify a number of advantages of the German concern:

1. The very first window from Rehau was installed in Germany more than half a century ago, it still stands, which makes it possible to judge the quality and durability of German products.
2. A wide range of design options allows you to bring any design projects to life.
3. The line includes models of different price categories - from economy to premium.
4. Their window frames are as warm as possible (up to 1.05 m2 ° C / W), quiet (up to 47 dB).
5. The products are constantly being improved, there are innovative models, reinforced in bulk according to our own technology, lighter, but at the same time very durable.
6. High quality double or triple contour double lobe gasket provides the best window sealing.
7. Excellent appearance - a snow-white, shiny, very smooth surface that does not turn yellow over time, practically does not get dirty, which reduces maintenance requirements to a minimum.
8. Operational warranty 60 years.

Proplex advantages

Windows from the Proplex company also have their undeniable advantages:

1. Manufacturing at a Russian plant in compliance with Austrian technologies - affordable quality.
2. Environmental friendliness of windows, Proplex is the first Russian company that does not use heavy metal lead in its profile. It has been replaced by calcium-zinc additives, which makes the products as safe as possible for humans and the environment (confirmed by EcoMaterial Green in 2017).
3. Scratches are not visible on the smooth semi-matt surface.
4. The products are unpretentious in care, they are easy to clean.
5. Good value for money.
6. The versatility of the components, which makes all the variants of the profile line compatible with each other.
7. Adaptation to any Russian climatic conditions.
8. Sixty year warranty.

The main differences between Rehau and Proplex

Rehau profile windows differ significantly from Proplex products, which becomes visible even with a superficial comparison of competitors' offers:

1. The range of the German concern is much wider, and for 60 years of vigorous activity it has developed more branded and unique manufacturing technologies than the Russian one for 20 years of existence on the market.
2. The minimum thickness of the window profile for Proplex is 58 mm, it has 2 or 3 chambers, the largest possible width of a glass unit is 24-34 mm, the resistance to heat loss is from 0.405 to 0.70, and for Rehau it is 60 mm, 3 chambers, 0, 64-0.65 m2 ° C / W.
3. The maximum performance of a Russian manufacturer's products is a frame 70 mm, 4 or 5 chambers, a glass unit 42 mm, resistance 0.80 - 0.82, a German one - 80-86 mm, 6 chambers, a glass unit 51-54 mm, resistance 0.90 - 1 , 05.
4. The Proplex company has a profile with minimal characteristics and cost in its lineup, intended for secondary glazing, for example, balconies or verandas, that is, in those places where aesthetics or cost savings are more important than warmth and silence.
5. Rehau has a unique code on each product by which you can check the originality.

Comparison of Rehau and Proplex profiles by characteristics

The main thing that you need to pay attention to when choosing a manufacturer is the technical characteristics and features of its products. To decide between Rehau and Proplex, it is necessary to conduct a detailed comparison of their profiles.

To lean in favor of one of the manufacturers, you should compare their offers for the following characteristics:

• wall thickness of window frames;
• number of cameras;
• the quantity and quality of the sealing contours;
• type of reinforcement;
• mounting width;
• thickness of double-glazed windows;
• appearance;
• operational period.

Waterproofing and quality of used seals

Good waterproofing is a guarantee that the window will subsequently not fog up, accumulate condensate, "grow" mold, and freeze. Waterproofing of pvc windows is carried out by means of a special seal located in contours, at Proplex, for example, in most structures there are two of them. Rehau also has basically two sealing circuits everywhere, except for the latest novelty. Geneo, in which there are three.

An important role is played by the material (mainly EPDM) of the seal, as well as its shape. Rehau has a double-leaf sealing gum without internal cavities. It does not collect moisture, does not stretch, does not age, retains all its properties unchanged, being in the temperature range from -40 to +120 degrees.

Sound and heat insulation

First of all, a plastic window should be warm, and secondly, it should be good to isolate the room from street noise. These properties are determined by the structure of the structure - its depth, wall thickness, number, size, location of air chambers, quality, quantity of the sealant. If we compare the maximum indicators of thermal insulation of plastic windows Proplex and Rehau by class, then the Russian manufacturer in the premium category is noticeably inferior to the German one - 0.81-0.82 versus 0.95-1.05. In other classes, the difference in resistance to heat transfer is not too obvious:

• economy - 0.64-0.65 for Rehau versus 0.64-0.70 for Proplex;
• the standard is 0.80-0.85 for the Germans versus 0.80 for the Russians.

As for sound insulation, Rehau also keeps its reputation here. In their budget models, this figure is 30-35 dB, in more expensive models - 45-47 dB. Proplex, on the other hand, does not specify the sound insulation parameter for the types of pvc profiles, but claims that in any of them it is at least 30 dB.

Reinforcement type

The strength of the window structure is determined by the presence of a reinforcing base inside it, made of steel tape with a thickness of at least 1.2 mm for small and at least 1.5 mm for large windows. An important nuance is the shape of the reinforcing insert. It can be P, G, G-shaped or square. The last is the strongest, but the G-shaped base is only slightly inferior to the square one.

Basic models of the Proplex window profile are made with U-shaped, and premium versions - with square reinforcement. With Rehau, the situation is similar - in budget variations, P-reinforcement, in more expensive G-reinforcement. It could be counted as a draw, but thanks to its latest development - the RAU-FIPRO fiber reinforcement technology, embodied in Geneo, the German manufacturer is taking the lead. The bottom line is that the reinforcing mesh is placed in the structure itself during its production, so additional reinforcement with a steel liner is no longer required. At the same time, the strength characteristics remain the same, but the weight drops by almost half, which expands the range of application of such frames and extends the service life of the fittings in them.

Installation depth of PVC profiles

The installation depth is the thickness of the frame in the opening. All properties and technical parameters depend on it. Considering the proposals of competing manufacturers, the following can be noted:

• German budget models have a frame of 60 mm, Russian ones - 58 mm;
• Rehau also has designs in 70, 80, 86 mm with heat conservation coefficients 0.80-0.85, 0.95, 1.05, the deepest Proplex profile - 70 mm, heat saving index - 0.80-0.82 ...

It follows that Rehau products are significantly ahead of Proplex products in this parameter.

Profile outer wall thickness

The thickness of the outer wall of the window frame largely determines its strength, durability, wear resistance, as well as resistance to various mechanical damage. World standards and Russian GOST (30673-99) set the minimum values ​​of the wall thickness from the outside for classes A (the best, at least 3 mm in the world, from 2.8 mm in Russia), B (from 2.5 mm), C (less than 2.5 mm).

At Rehau, all standard and premium types have a wall thickness of 2.8, 2.9, 3 mm, respectively, belong to the highest class. Walls in budget variations with a thickness of 2.7 mm, which allows them to be classified as class B. The Proplex plant has only a pvc profile Premium belongs to category A, the rest to B or even C.

Number of air chambers

The main technical characteristic of the window profile is the number of chambers, which for Proplex varies from 2 to 5. Rehau has options with 3-6 chambers. Air chambers, more precisely, their number and size, are responsible for keeping the rooms quiet and at a comfortable temperature. The more there are, the higher the energy-saving and noise-insulating performance.

At Proplex windows, the leaders among the offers ( Hit, Premium) have five chambers, and the heat saving rate is 0.81-0.82. Rehau is doing much better. Their five-chambered Delight, Brillant, Grazio resistance to heat loss is 0.80, 0.81, 0.85, and in six-chambered Intelio, Geneo- 0.95, 1.05. The difference is obvious.

Maximum glass unit thickness

The thicker the glass unit is used in the window, the quieter and warmer it will be in the room. Thick double-glazed windows can only be installed in a deep frame.

The German concern has offers:

• 60 mm for a glass unit up to 32 mm ( Blitz, Euro);
• 70 - 41 mm ( Delight, Brillant, Grazio);
• 80 - 51 mm ( Intelio);
• 86 - 54 mm ( Geneo).

The profile from Proplex lags significantly behind in this regard, it has:

• 58 mm and allows you to install a double-glazed window 24-34 mm ( OUTLINE, Basis, Optima);
• 70 - 42 mm ( Comfort, Premium, Hit).

Appearance and service life

Competitors' windows also differ in appearance. Rehau's designs are as smooth as possible, shiny, glossy with a bright white surface that does not turn yellow, does not turn gray, does not fade over time. At the same time, dirt practically does not linger on it, which makes it possible to replace the thorough washing of the frame with wiping it with a damp cloth just a couple of times a year.

The profile for plastic windows from Proplex does not have a bright white color, it is rather milky with a semi-matt non-shiny surface. Looks stylish, but somewhat dull. But on it scratches are practically not visible. The dirt retains, but is washed off quite easily.

In terms of service life, both companies guarantee 60 years of maintaining the profile of all its quality characteristics.

Comparison table of Rehau and Proplex profiles

To summarize the comparison, it is worth once again referring to the main characteristics of the Proplex and Rehau profiles, for convenience, collected in one table.

Manufacturer	Series	Glass unit thickness, mm	Number of air chambers	Thermal protection coefficient, m2С / В T

Comparing the profiles of competitors, it can be noted that the 58 mm Proplex designs are similar in technical characteristics to the 60 mm Rehau products. They are just as warm and quiet, but they are inferior to the Germans in strength, since the thickness of their outer walls does not even reach class B.

The 70-mm Russian profile for pvc windows is positioned by the manufacturer as a premium product, while the Germans only belong to the standard class, while in terms of heat saving, albeit just a little bit, Proplex loses (0.80-0.82 against 0 , 80-0.85). Premium offers from Rehau have a thickness of 80, 86 mm, as well as maximum heat retention and sound insulation (0.95-1.05.47 dB).

Price comparison Rehau and Proplex

An important factor is the cost of products. Both manufacturers rank their products in the middle price category. For completeness, it remains only to compare the approximate prices for the same windows, for example, double doors from Proplex and Rehau.

Manufacturer	Name	Price for a double-leaf window, rub.

The prices given in the table for plastic windows Rehau and Proplex reflect only the approximate cost of a two-leaf structure (1300 * 1400) with one blind, second swing-out sash, excluding installation, slopes, window sill. The table shows that Russian offers are 25-30% cheaper than German ones.

Profile - the basis of a window from any manufacturer. The quality of the profile determines the service life, reliability of the entire window block. If there is no relevant experience, then you can decide that all profiles are the same. The difference can appear after installation and many years of operation. If cracks appear in the window, there are constant drafts in the room, then the window can hardly be called high-quality.

Rating of the best manufacturers of plastic windows in Moscow and Moscow region

On this page, we will try to describe all the advantages of a metal-plastic profile from leading manufacturers, as well as suggest which criteria are best for choosing plastic windows. This information will tell you which plastic windows are best to choose for your home, apartment, office or warehouse.

On the Russian market there are window designs from companies from different countries. The leading position is occupied by window profiles from Germany, Slovakia, Korea and Belgium. Among them there are popular, "promoted" brands, as well as very young companies that have already firmly taken pride of place on the pvc product pedestal.

The profiles of the German company VEKA are in the greatest demand on the metal-plastic products market. This company produces several types of profile window systems, which plastic windows are suitable for living quarters? Profile PVC system VEKA Softline AD is the best option. Frame and sash design - five-chamber double sealing system.

The VEKA Topline Plus profile is supplemented with special inserts made from the effective heat insulator Neopor. This material is a kind of polystyrene with the addition of silver. It has antimicrobial and antifungal effects, and also helps to increase heat protection.

The installation depth of such a profile is slightly increased and is 10 cm, which must be taken into account when measuring the window opening.

It should also be noted that a new product from VEKA was released in 2008 - a profile PVC system - Softline XXL. The thickness of the outer wall of the profile is 4 mm, which increases the quality characteristics of the entire structure as a whole and of the welded seam in particular. Along with this, VEKA is gradually losing its positions, as new companies appear, offering more "fresh" and original solutions, as well as selling goods at real prices without markups for the brand name.

Another world famous company is REHAU. It represents a large assortment of goods from economy to elite class. The profiles of this brand are distinguished by excellent sound insulation and good thermal conductivity. The most popular REHAU systems are: Basic-Design, Brilliant-Design and Sib-Design. It is difficult to say which are the best plastic windows from these types. The first two are almost identical and differ only in the number of cameras in the profile.

Basic-Design has a three-chamber frame and sash structure, while Brilliant-Design has a five-chamber structure. The last model differs in that the design allows the installation of a double-glazed unit with three panes. In addition, REHAU offers various systems of additional and support profiles, which increase the stability and durability of window structures throughout the entire period of use.

KBE is one of the largest global concerns with an official subdivision in the Russian city of Voskresensk. Today the company offers two main types of profile systems - Etalon and Expert. The etalon is the most accessible of all KBE profiles. It has a three-chamber frame and sash structure, a reinforced insert and climatic valves. The Expert system was developed taking into account the increasing requirements for thermal insulation.

The coefficient of the reduced heat transfer resistance in the profile without reinforcement is increased to - 0.81 m2 ° C / W.

It is difficult to say which plastic windows are better - Etalon or Expert. It all depends on the room in which they will be installed and what is the purpose of their operation. The first option is suitable for buildings and structures located in a temperate climate. In severe frosts in winter, such windows can freeze in the area of ​​the hinges.

The Russian-Austrian company MONTBLANC produces metal-plastic structures using the most advanced technologies. The product line consists of six types of profiles having three. five- and six-chambered structure. For a more convenient and rational installation, MONTBLANC also offers a wide range of auxiliary, additional profiles, fittings and other functional elements (window sills, ebbs).

The PROPLEX company is based on the territory of Russia in the city of Podolsk. It produces metal-plastic entrance, window and balcony structures from German materials according to Austrian innovative technologies. Plastic profiles PROPLEX are specially adapted for Russian operating conditions. Another advantage of this company is the availability of fittings and components in the warehouse. At any time, you can buy an additional profile or fasteners for installation, without waiting for their delivery from abroad.

The most popular Proplex systems are: Proplex-Lux, Proplex-Premium and Proplex-Optima. A unique feature of the Lux profile is a four-chamber frame and a three-chamber sash, with the possibility of combining a sash with a three-chamber frame. The official representatives of the company will tell you in more detail which plastic windows are better to choose from the above options.

For connoisseurs of creative design solutions, we recommend paying attention to the ALUPLAST profile systems. This company offers more than 40 unusual decor variations that allow you to create interesting and unique interiors. In addition, Alyuplast products have a RAL certificate, which assigns the status of a high level of consumer properties to the product. All ALUPLAST window systems have a 13 mm European hardware groove and a triple sealing system to ensure increased burglary resistance.

SALAMANDER

SALAMANDER PVC systems are the perfect combination of aesthetics and functionality. The traditional design for the profile of this company is a rounded contour. The company offers three main types of profile systems: 2DDesign, 3D Design, Streamline Whoever has not yet chosen which plastic windows to install, we recommend paying attention to the third model. Here, on the inner side of the frame, there are additional fastening lugs, which ensure the reliability of fastening fittings and locking mechanisms.

Thanks to the presence of a collector, a shutter and a surface with a double slope in the rebate, rainwater and condensation are quickly drained out even in a shower, and water does not seep under the glazing even when the sash is tilted.

The Korean company LG CHEM was a novelty in the market of metal-plastic structures. Many are accustomed to seeing only electronic equipment and all kinds of devices from this brand, but in fact, 12 representative offices have already been opened around the world that produce window profiles. L-600 and L-700 PVC systems have a high heat transfer resistance coefficient of 0.91 m2, due to which the room maintains a normal air temperature even with passive heating.

In this large section of the article, we examined the main characteristics and distinctive features of the profile systems of the most popular manufacturing companies around the world. As practice shows, the best plastic windows are produced by German firms. They constantly improve the technological process, invent new functional elements and strictly monitor the quality of raw materials and raw materials.

Among the domestic manufacturers of plastic windows, namely those who independently extrude the profile, the Lipetsk company Schtern can be distinguished. You can read more about this company and its products in our article "Plastic windows in Castorama", because they are one of the dealers of OK Schtern.

What are the best plastic windows? Advantages, disadvantages, reviews of popular PVC profiles

We are aware that by compiling a rating of windows, thereby intruding into the territory of professionals who are very skeptical about the assessments of this product. But "Price Expert" would not have been himself if he had not tried to rank everyone.

To understand the subtle nuances of the assessment, we had to study a considerable amount of informational texts, a huge number of all kinds of amateur and professional reviews, and conduct a little research of our own.

The product, about whose description so many copies have been broken, is in fact the most ordinary plastic stick, but, however, with a complex surface and internal structure. To give strength inside the profile, there is a metal insert made of galvanized steel, and internal plastic partitions create air chambers to retain heat. Everything.

It seems, what is there to argue about? Steel, it will remain steel, so that they do not do it with it, and the plastic used by all companies is the same - polyvinyl chloride (PVC). It follows that the window profile of any production must be of the same quality. Is it so? And how do you choose the best of the same by definition?

The average price in the Russian Federation of a window with a size of 1470x1420 from a profile with a thickness of 70 mm: 9500 rubles

The profile is issued near Moscow by the VEKA Rus company. This is the first such enterprise in Russia. In addition, there are branches in Novosibirsk and Khabarovsk. The headquarters of VEKA AG is located in Germany in Sendenhorst. The company produces six types of profiles:

• EUROLINE - three chambers, 58 mm wide
• PROLINE - four chambers, 70 mm wide
• SOFTLINE - five chambers, 70 mm wide
• SWIGLINE - five chambers, 82 mm wide
• SOFTLINE 82 - six to seven chambers, 70 mm wide
• ALPHLINE - six chambers, 90 mm wide

The products are certified according to ISO 9001: 2008. The profile of the VEKA company has been awarded the German RAL quality mark, which means that the procedure for controlling the used raw materials and finished products complies with the control standards.

• Stable quality
• Large product line

Typical reviews about VEKA windows: “The profile itself is good, in winter it showed itself well, pah-pah, but in truth - it's expensive. I am still inclined to believe that this is an overpayment for the brand. "". the company is quite well-known, it seems to me that in our city we have the most advertisements for this particular company. And banners hang along the roads, and the press writes on the main pages, and videos are shown on TV "

Varieties of double-glazed windows

A profile is the basic or basic element of the entire structure. The choice of a profile determines both how the window will look and how much it will fully serve its owner. The most common material is PVC (polyvinyl chloride). The interior of the profile is hollow, which contributes to better thermal insulation of the window; metal inserts are made there for strength.

To date, up to fifty companies are engaged in the production of a profile only in Russia and Europe. And each can offer different options. Among the most popular and high-quality ones are KBE, Gealan, Veka, Rehau, SCHUCO, etc. Manufacturers guarantee up to 40 years of flawless work without cracks and yellow spots.

Glass is no less important parameter in the manufacture of windows than the profile or the presence of reinforcement. It is pre-polished. For the sunny side, you can provide for the presence of a sunscreen film. Many people confuse the number of cameras in a glass unit and cameras in a profile. For a double-glazed window, the glasses are connected in a special way with the help of sealants and frames. Air gaps are required. It is possible to fill the inner space of the chambers of the double-glazed unit with a special gas.

In a single-chamber double-glazed window, only 2 glasses are connected. In most cases, single-chamber bags are used for cold rooms, balconies, loggias. For residential premises, single-chamber bags are not used due to low thermal insulation. These options are difficult to attribute to the best PVC windows. For an apartment or a private house, office space, it is better to focus on a double-glazed unit with 2 cameras and 3 glasses. In this case, the thermal insulation increases immediately by 50%. The third glass provides both heat and sound insulation.

Installation of 3-chamber variants is also not recommended. They have significant weight, require special strengthening of the base, and provide poor insolation. 3-chamber double-glazed windows are recommended only for the Far North, where operation in conditions up to -400C is possible.

Which double-glazed window to focus on when choosing a window - with 1, 2 or 3 cameras. First you need to study the design of each. Then the choice will not be a problem.

Up to 80% of the area of ​​a standard window is a double-glazed window. Glass in most cases is used with a thickness of 4 mm, most often quartz. When choosing, it is important to look at how clean the cameras are offered by the seller. It will not be possible to wash the gaps between the glasses after installation, with all the desire. What to choose plastic windows so as not to observe cloudy stains between the glasses?

Today, the following types of double-glazed windows are most common:

• With energy saving function. On the inside, the glass is treated with a special compound that reflects heat into the room.
• Sunscreens. Installation of tinted glasses or application of a special film is possible.
• Armored. Glasses have increased strength. Most often used for lower floors and shops.
• Tempered. If you break such glass, then there will be no sharp fragments. A similar technology is used in the automotive industry.
• With additional reinforcement. An additional metal mesh is mounted in the glass.
• Self-cleaning function. A special compound is applied to the surface to prevent dust and dirt from settling.

A glass unit in comparison with traditional window glass is a complex structure. This is a block of glass sealed together. The space between the two glass sheets is called the chamber. It should not be confused with those included in the profile.

The ability to keep warm and keep out noise depends on:

• From the thickness of the glass unit. A double-glazed window with a thickness of 32–44 mm is suitable for a house or apartment.
• From the number of cameras. Usually a double-glazed window consists of 3 glasses and 2 chambers between them. For a harsh climate or houses located in places with a high noise level, three- and four-chamber packages are produced. Single-chamber ones are suitable for arranging balconies, loggias, gazebos.

• From the width of each double-glazed chamber. The larger it is, the better the insulation performance. However, after 24 mm, the increase in thickness no longer increases the positive properties of the product.

• From filling the chambers. The inert gas pumped between the glasses reduces heat loss, protects against noise and ultraviolet radiation. Argon retains 50% more heat than air, krypton - 2 times more than argon.

• From the thickness of the glass. If a 5 or 6 mm external glass is installed in a window facing a busy street instead of the standard 4 mm glass, the sound insulation will increase, but not significantly. And glasses of different thickness will not resonate with each other.

• From the type of glass. It makes sense to choose a material that is more expensive, but with additional useful properties. Low-emissivity glasses that reflect infrared rays keep your home warm in winter and cool in summer.

Glass types

To obtain low-emission glass, the thinnest metal film is sprayed on it.

• K-coating - a tin film, reduces heat loss by 25% in a single-chamber glass unit.
• I-coating (i) - a layer of rare earth metals, retains more than 30% heat. It is installed only from the side of the room, the cover is turned inside the camera, since it is unstable to mechanical damage. Often marked as E-low.

Due to such glasses, a single-chamber double-glazed unit approaches in thermal insulation properties to a two-chamber unit and may even exceed them.

Let's look at an example. Ordinary double-glazed windows for a private house cost the owner 150,000 rubles. In winter, you have to pay 8,000 rubles for heating. per month, and in the summer due to the operation of the air conditioner for electricity you have to pay 600 rubles more. per month. If the owner of the house had installed thermal packs, he would have paid 180,000 rubles for them.

It is practically impossible to break glass laminated with triplex. Glasses reinforced with special metal or polymer meshes have the same quality.

INTERESTING FACTS!

• The energy-saving i-glass was invented by accident. Japanese scientists have been doing research on the development of radiation shielding and have found that some metals applied to glass reflect heat. First, this technology found application in space research, and now it is used in the manufacture of insulating glass units.
• Scientists still have not been able to explain one amazing phenomenon. After 39 years of operation of the plastic window, the outer wall of the profile becomes 0.75 mm thinner. Not a single version explaining this fact has yet been recognized as sufficiently reliable.
• Laminated glass triplex was also created by chance. The famous French scientist Edward Benidictus dropped a glass flask on the floor. It cracked, but did not shatter into pieces. And the reason for this was a mixture of cellulose nitrate, which solidified on the walls of the burst flask and created a layer that did not allow the glass to disintegrate.

The structure of a glass unit can be understood by the marking, which indicates the thickness of the glass, the width of the chambers, and the type of coating. For example, the designation 4-12Ar-4-12 Ar-4I stands for:

• double-glazed window;
• glass thickness - 4 mm;
• the distance between them is 12 mm;
• I-type inner glass;
• the chambers are filled with argon.

The following tables will help you choose the ratio of the parameters of double-glazed windows.

Spacer frame

The frame between the glasses sets the distance between them, which ranges from 6 to 24 mm. Frames are made of aluminum, steel, plastic. Spacers made of stainless steel or plastic conduct heat to a lesser extent and do not allow a cold bridge to form, therefore they are considered the best option.

The second function of the frame is to absorb moisture. It has an absorbent inside that absorbs liquid, preventing the windows from fogging up in winter, and there is perforation on the surface.

To choose reliable double-glazed windows, you need:

1. Make sure that there are markings with the manufacturer's logo, date of issue and information about the components. Her absence is a cause for serious suspicion.
2. Examine the glass for chips, cracks.
3. Check the quality of the seal. There should be no traces of liquid sealant along the strip that regulates the distance between the glasses. The outer layer of the product should look even and neat. Sagging, cracks indicate the unreliable quality of the package.
4. Determine the accuracy of the geometry using a tape measure. The difference in measurements along the diagonals (more than 3 mm) proves that the parameters of the glass unit do not meet the standards. The thickness of the bag, which is measured with a caliper, cannot differ from the declared one by more than 1 mm.
5. Measure the displacement of the glass planes with a square. A deviation exceeding 1 mm indicates non-compliance with the standards.
6. Determine the transparency of the glasses, the presence of water and steam in the chamber.

To give the window a more sophisticated look, so-called spros are used (see photo).

They can vary in color, thickness, be located between glasses or on top of them.

Built-in blinds can be a convenient addition to the window structure. They are located directly in the glass unit chamber, and are controlled from the outside. But such a system has a serious drawback - the impossibility of maintenance and repair.

• Minimum parameters: double-glazed window 4-10-4-10-4. This is a generally accepted standard with good sound and heat insulation characteristics.

• Optimal parameters: double-glazed unit 4-16Ar-4-14Ar-I4. There are all the necessary additions here: wide chambers of different thicknesses for better noise protection, argon filling, energy-saving glass.

Memo for choosing a plastic window

In modern times, manufacturers of plastic windows regularly improve product quality by introducing new and improved technologies. But still, when buying, you should pay attention to some of the nuances:

1. Appearance . The window is one of the primary attributes in the interior, even the highest quality window with an inappropriate design will look out of place in the interior of the room.
2. Type of construction. Windows are blind, swing and swing-out. The swing-out design is more convenient to use.
3. Number of leaves... The choice depends on the size of the window opening.
4. Number of cameras... The most reliable protection against severe winter frosts is the three-chamber design of the window unit.
5. Hardware quality... So that the sash does not warp later, pay attention to the quality of the pivot mechanisms.
6. Manufacturer. Give preference to trusted, trusted brands.
7. Window installation wizard qualifications... Even the most reliable and high-quality double-glazed window can be spoiled by an incorrect installation. If the master treats his work negligently, in the winter months, drafts can pass through the window, the sashes will warp, moisture will appear due to insufficient tightness. To avoid this, entrust the installation of windows only to trusted companies.

11. Schuco

On the portal Marka.guru, we select only the best manufacturers for the production of plastic windows, and the rating is completed by the Schuco company. Details of profiles and fittings are supplied to the company by Germany.

Advantages:

• modern design;
• structural reliability;
• the possibility of remote control;
• heat loss protection;
• high noise insulation.

Disadvantages: the appearance of condensation.

The metal-plastic profile for windows, doors and balcony blocks is: one-. two-. three-. four-, five-chamber and even more complex designs. The heat-saving effect depends on the number of chambers. Therefore, the fewer cameras in the profile, the cooler it will be in the room in winter.

Single-chamber frames and sashes are more suitable for storage and office spaces. For residential buildings, the best option is three-chamber and four-chamber. They provide a normal room temperature and are relatively inexpensive.

Windows with a large number of cameras are used extremely rarely, mainly in regions with a harsh harsh climate, for example, in the Far North. Each chamber cavity has its own purpose: to provide strength, for the outflow of condensate, for attaching fittings.

For large-sized window blocks, a heavy-duty reinforced profile is used.

Its central chamber is reinforced from the inside with a U-shaped or closed galvanized steel insert.

Wall thickness of the plastic profile

Profiles can differ in thickness (the most important parameter for a window structure for any purpose). The next most important characteristic is the number of sealing circuits. You can proceed from the design when buying.

In Europe, the main document governing the production of translucent structures is EN 12608 SR. In Russia, manufacturers are obliged to proceed from the requirements of GOST 30673-99. Both documents regulate the use of polyvinyl chloride in the manufacture of translucent structures.

1.class A. The outer wall must not be thinner than 2.8 mm. For the inner walls, the indicator is reduced to 2.5 mm. Provides better thermal insulation;

2. class B. Outer walls - not thinner than 2.5 mm. Internal - not less than 2 mm. Compared to a profile of class A, they are more susceptible to deformation (tests show up to 15% difference in stiffness);

3. profiles of class C. This class includes all profiles that are not included in the other two groups. There are no additional requirements.

For industrial, non-residential premises, the "object" version of the profile is intended. It is not recommended for apartments and private houses: thermal insulation is poor, easily deformed. It can only be recognized by the presence of the object marking. In most cases, when they offer to buy an economy-class profile, they mean this option for a cheap, but not too high-quality profile.

It is rather difficult for a non-specialist to determine by eye whether the profile is of high quality and which plastic windows are the best. But there are several points to which you can and should pay attention.

Homogeneous structure

There should be no foreign inclusions, rough surface, grains, streaks. If at least one of the listed signs is observed, it is better to refuse the purchase. Important. If you are afraid that a low-quality profile will be sold to you, look at the markings inside. If there is a stamp or brand of the manufacturer, you can be sure that the profile is of high quality. In addition, the release date, change and information about the equipment are stamped.

Certification of translucent structures

The legal framework of Russia provides for mandatory certification of the profile used for the production of windows. Ideally, the products are certified according to RAL requirements, which evaluate not only the product itself, but also the manufacturing enterprise. A profile may belong to the same class, but it is produced by different companies and has a different quality. Accordingly, the certificate may not be awarded. And the window will be difficult to attribute to high-quality plastic windows.

How profile width affects quality

The most popular width is 58-60 mm. A similar profile is used for private and multi-storey buildings. Wooden frames had the same width, which later gave way to plastic. At the moment, a profile with a width of 58-60 mm is considered the most optimal for any climate.

For high-rise buildings, areas with increased wind load, northern latitudes, a profile width of 70 mm will be more optimal. The buyer gets the best thermal insulation.

The VEKA company offers 70 mm profiles in the SOFTLINE, SWINGLINE and PROLINE product lines.

The most expensive profile is 80-90 mm. It is used on special, exclusive occasions. In Russia, a significant part of window manufacturers do not use this profile in their work.

Important: there should be at least 2 rows of sealant on the frame of a high-quality PVC window. This guarantees the absence of condensation, and as a result, violations in the waterproofing. The accumulation of condensation is a guarantee of mold, fungal colonies and other unpleasant consequences.

What plastic windows are best for an apartment? The quality rating of plastic windows, compiled in 2018 based on user reviews from the Irecommend and Otzovik sites, will help to answer this question.

Also, when compiling the window hit parade, such criteria as the durability of the company, the popularity of the products, the quality of service and, of course, the price were taken into account.

10. Panorama

The cost of a double-leaf window is from 7,500 rubles.

Over the years, the St. Petersburg firm has glazed over one and a half million square meters.

So far, users are saddened by only one thing - that the company's service is so unobtrusive that it is difficult to get information about possible options.

9. SOK

Cost - from 14,000 rubles.

SOK, or "Samara Window Structures", was founded in 1999. The company does not have its own production, and the profiles are made under the patronage of the German concern Profine.

Cons: Windows may turn yellow, possibly due to a breach of technology at a Russian manufacturing plant.

8. Deceuninck

Prices - from 9 500 rubles.

The Belgian concern The Deceuninck Group is one of the top three manufacturers of PVC windows around the world.

It is important that the company's windows are ISO certified. Cons: The company's cheap options are generally worse than similar budget offerings on the market.

7. Proplex

Prices - from 8 703 rubles.

Proplex windows are manufactured in the Moscow region on Austrian equipment, and raw materials and components from leading suppliers from the USA and European countries are used in the production.

Although Proplex windows are more likely to be positioned as a budget product, they are of sufficient quality even for Siberian frosts. PVC has good quality - it does not crack or yellow over time.

Users' complaints are mainly caused by the fittings - their quality leaves much to be desired.

6. Kaleva

Cost - from 9,000 rubles.

Kaleva is a Russian full-cycle window company. This means that they make the windows exclusively by themselves, starting from the development of the window and ending with its installation.

The advantages of the company are an extensive network of dealer companies with representative offices in more than 80 cities of Russia. Unfortunately, one of the drawbacks is that the quality of both the windows themselves and their installation very much depends on the dealer company.

Without seals, the tightness of double-glazed windows, tight closing of the window are impossible. They are made from rubber, thermoplastic, thermopolymer and silicone.

1. The rubber seal is the most inexpensive, but also short-lived. Cracks from heat and frost. It is easy to replace it, it is always on sale.
2. Thermoplastic (TPE) is the most common because it is suitable for use in automated assembly lines. It has excellent characteristics, but with frequent opening and closing of the window, it quickly wears out, since it becomes fragile from temperature extremes. Inexpensive, easy to change.
3. Thermopolymer (ethylene-propylene rubber, EPDM) is a more resistant material. Installed on expensive and moderately expensive windows. For replacement, it is advisable to call the master.
4. Silicone is the best sealant. It is not erased, not deformed, resistant to temperature extremes, cleaning agents. But it is expensive and difficult to find on sale.

Do I need to count how many cameras are in the profile?

The number of chambers in a profile is determined by its thickness and ranges from 3 to 8. The most popular among window manufacturers are 3- and 5-chamber profiles.

1.drainage of condensate; 2. an insert is made of metal reinforcing the structure; 3. Fastening of hinges and fittings, ensuring thermal conductivity.

If the windows of a house or apartment face the south side, there is no special traffic, you can limit yourself to a 3-chamber profile. If the windows are located on the north side, face a noisy street, it is better to choose a 5-chamber profile for the best plastic window.

The 58 mm profile does not imply more than 3 chambers. In a 70 mm profile, there can be cameras from 3 to 5. The difference between a 5-chamber profile and a 3-chamber profile is in the presence of cold bridges in the places where external fittings are installed.

When choosing the thickness, it should be borne in mind that the 70 mm profile presupposes the installation of a 44 mm glass unit, which provides better thermal insulation than a standard 32 mm glass unit installed in a 58 mm thick profile.

In the 90 mm profile, there are standard 6 chambers and a double-glazed window up to 50 mm. With such a profile, no cold or noise outside the apartment or private house is scary.

Mid-range companies with ambition

In November, the activity of the leading players in the Russian window market usually begins to decline. In these conditions, the role of consulting sales managers is of particular importance.

And if Yunis Group from Togliatti confirmed its claims to leadership (2nd place with 99 points in October), then the Bosphorus from Pyatigorsk made a leap from 4th place, adding three points at once.

Over the past few months, Eurookna has significantly improved the level of its consultations and continued to move forward in the ranking, reaching 3rd place.

A place	Company	Region	Score
1	Bosphorus	SOUTH	100
2	Yunis Group	Volga region	100
3	EuroWindows	Moscow	98
4	KARVI	DV	97

17	Gallery of windows	CR	89
18	Tyumen-Design-Service	Ural	89
19	These are the windows	Volga region	88
20	DomCom	Moscow	88

A negative trend in November was the decrease in the passing score in the TOP-20. In November, the minimum indicator decreased by 2 points and amounted to 88 points.

The general trend of consulting in recent months is the inability of sellers to correctly select a complete set of windows in relation to the identified needs. The identified needs of the client are not reflected in the configuration of the window. During the consultation process, a few managers make a short presentation about the company itself and talk about its advantages.

The positive aspect of consulting is that companies pay more attention to the sale of high-quality window sills and provide the client with more information about the brands of fittings and their properties. The leaders of the rating pay a lot of attention to identifying the needs of buyers, not losing sight of the problems of people with disabilities and issues of child safety.

The Golden Window rating is formed monthly according to the methodology. Experts monitor the quality of the work of window companies in the field of telephone sales using a telephone survey using the "Mystery Shopper" method.

The results of monthly surveys are summed up over the year and divided by 12, thus calculating the average annual score for the company.

The best selling companies with the highest average annual scores will traditionally be awarded the Golden Windows in the spring of 2018 during the Fensterbau Frontale in Nuremberg.

Data from leading manufacturers are taken as a basis.

In Russia, you can buy plastic windows with a profile from a variety of manufacturers. And how to choose the most optimal one? Now is the time to study in more detail the information about the manufacturers and the products they offer. What are the best quality plastic windows?

1. Rehau. The company is known all over the world. It has been producing only high-quality profiles and no less reliable windows for over 50 years. Windows from Rehau are distinguished by their exquisite design and environmental friendliness. The company offers to the market a profile of the middle class with a thickness of 60-70 mm.

REHAU offers its customers a choice of the following profile options for the best PVC windows: - GENEO with a non-standard width of 86 mm and 6 chambers; - INTELIO with a width of 86 mm and 6 cameras; - BRILLANT-DESIGN. The width can be 70 or 80 mm. In the first case there are 5 chambers, in the second - 6 chambers; - DELIGHT-DESIGN. With a profile width of 70 mm, 5 full-fledged cameras were mounted; - SIB-DESIGN.

The advantages of REHAU are numerous: - windows are distinguished by good frost resistance, provide heat and sound insulation; - the buyer can choose a profile of any width and design; - quality assurance

The disadvantages include the high cost even against the background of brands offering similar products.

2. VEKA. The location of the concern in Germany can already be considered a sign of good quality. One of the few companies that produce not only white, but also a color profile that does not change its quality characteristics during the entire service life. For the manufacture of seals, only natural rubber is used, which does not freeze in frosts and does not dry out in summer. The company offers profiles from 58 to 90 mm. The price of the VEKA profile is comparable to the price of Rehau.

VEKA was one of the first to enter the Russian market. Production facilities have been opened and have been operating for a long time in the Moscow region ("VEKA Rus") and Novosibirsk. The products are sold all over the country.

The buyer can choose from 6 types of profile: - EUROLINE profile. Width - 58 mm. There are only 3 cameras; - PROLINE profile is produced with a width of 70 mm and 4 chambers; - the SOFTLINE profile is offered on the market with a width of 70 mm and 5 chambers; - SWIGLINE profile has a non-standard width of 82 mm and 5 chambers; - SOFTLINE 82 profile with a standard width of 70 mm has 5-6 chambers; - ALPHLINE profile with a standard width of 90 mm has 6 chambers.

The production of windows is certified according to the international system ISO 9001: 2008 and in accordance with the German quality standard RAL. The user can be sure that he is purchasing only the best plastic windows.

The advantages of VEKA include the high quality of products, the presence of a rubber seal, the ability to choose a profile of any width and operation in the Caucasus and Yamal. There is only one drawback - the high price.

3. Trocal. This company was one of the first to offer plastic windows to the market - in 1954. The profile can be standard, at the request of the customer, lamination, acrylic coating, etc. is performed. The profile is based on Greenline technology, which does not harm the environment. The company offers to purchase a profile with a width of 70 mm. It is noted that the profile is quite rigid and not subject to deformation. But at the same time it is not recommended for the production of heavy doors.

4. Salamander. The products of this manufacturer are less known than Rehau, but are not inferior in quality to any of the German manufacturers. The production is located on the banks of the Rhine, there are no branches in other countries. The price matches the quality. The range of the company includes a profile with a width of 60-70 mm. The SALAMANDER company can be considered one of the best at the European level, but in Russia this product is not yet in great demand.

If you buy the best plastic window from Salamander Industrie, then you can be sure that it is made in Germany. Only one branch operates outside the country - in Brest. If the window seller offers a BRÜGMANN profile, you can safely buy. It is also SALAMANDER, but manufactured outside of Germany.

On sale you can find profiles of the following types from Salamander Industrie: - Design 2D - standard version with a profile width of 60 mm and 3 or 4 cameras; - Design 3D. Profile width increased to 76 mm. Added 1-on camera; - Streamline. With a profile width of 76 mm - 5 chambers.

Salamander Industrie products are distinguished by a number of advantages: - the outer surface of the profile is of ideal quality; - thoughtful design; - European quality. The parent manufacturer controls the work of its dealers. The disadvantages include only the excessively high cost for Russia.

5. KBE. In Russia, this brand is the most popular and in demand. Awarded certificates allowing the use of the products of this company in medical institutions and kindergartens. The manufacturer guarantees up to 50 years of flawless work. You can choose both an ultra-expensive profile option and an economy class. On sale - profiles of 58-70 mm.

In Russia, the bulk of KBE-branded products are manufactured in Khabarovsk or Voskresensk. KBE products differ from their competitors REHAU and VEKA only in lower price. The quality is up to the mark. The company is actively practicing issuing certificates of partner manufacturers to customers, which allows to increase sales.

In Russia, you can purchase the following KBE profile options: - Standard and Engine. The buyer receives standard 3 cameras and a width of 58 mm; - Standard. One more camera has been added to the standard Etalon package; - KBE_SELECT. Option for northern latitudes and multi-storey buildings. Profile width 70 mm, number of chambers - 5.

- KBE_Expert. A variation of the previous version with the same number of chambers and profile width; - KBE_Expert. It differs from the main modification only in the mounting width of 127 mm; - KBE_Energy. With a profile width of 70 mm - only 3 chambers; - KBE_88. Non-standard version with a profile width of 88 mm and 6 chambers.

Among the advantages of KBE products, it is necessary to highlight: - relatively low cost with excellent quality; - a large selection of different profiles designed for any latitude and operating conditions. Both at a temperature of 500C and at -500C, windows will not lose their qualities; - good heat and sound insulation.

Experts were able to highlight a small minus attributable to KBE products: plastic may turn yellow during long-term use. In general, the answer to the question "What are the best quality plastic windows?" in relation to KBE, it will be rather positive.

6. Proplex is the most famous Russian manufacturer of window profiles. Russian climatic realities are fully taken into account. And the production works under the supervision of specialists from Austria. The buyer can choose a profile with a width in the range of 58-127 mm. Production is established at a plant in Podolsk (Moscow region).

PROPLEX is the first completely Russian manufacturer of PVC window profiles. Initially, the profile was purchased abroad. Later, the company switched to the production of windows entirely of its own production. The development was attended by engineers from Austria specializing in thermal insulation products and systems.

Reinforcement

PVC windows are not quite rightly called plastic. One of the chambers of the profile is specially allocated for laying the reinforcement. From this, the structure becomes more rigid and durable. And here it is important to check in a timely manner whether the window is actually reinforced. This can be done quickly enough with a magnet.

Erroneous action blocker

Be sure to make sure that this mechanism is provided in your window. Finding out the presence of a blocker is quite simple. It is enough to open the window and try to switch it to the tilt mode. If, as a result, the window is held only on the lower hinge, then the manufacturer has saved on the blocker. It is better to refuse a purchase. This option is not among the best plastic windows.

Slopes

A manufacturer who does not save on quality chooses sandwich panels with additional insulation for slopes. This is the only way to guarantee the absence of mold, fungal colonies. Sandwich panel slopes retain their consumer qualities for many years without deformation and distortions. If there are joints between individual slopes, then the manufacturer or installer must ensure that they are filled with liquid plastic. The use of silicone is not permitted. In a maximum of a month, the seams will have to be covered over again.

An important advantage of liquid plastic is that the structure is identical to that of the profile. Accordingly, there will be no differences in color, cracks and deformation. Silicone tends to darken. It does not create a barrier to mold and mildew. The seams will have to be sealed over and over again.

PVC window installation

Most of the complaints from the owners of metal-plastic windows are due to poor-quality installation. In order not to later complain that it is blowing from all the cracks, you need to make sure that the team of installers uses only special foam for windows, but also vapor barrier and waterproofing tapes (PSUL).

A plastic window consists of many individual parts and assemblies. But it will perform its function only when every detail works properly. Accordingly, when choosing a window, you need to check not only the quality of the profile, but also the fittings, gaskets, double-glazed windows and many other components. And then the question "Which plastic window to choose?" will not be difficult for you.

The principle of operation and the device of plastic windows

Plastic windows are not a novelty on the Russian market for a long time. For many years they have been successfully replacing ordinary wooden frames with glass and are in demand, as they have a pleasant cost, are reliable, functional, durable and very convenient. They are installed both in apartments and offices. However, the great popularity of the products has led to the fact that now a lot of manufacturing companies have appeared on the market, and not all of them produce good products. Therefore, it is important to know how to choose the right windows so that you will not be disappointed later and not regret the money spent.

When choosing a window, you need to take into account all the parameters. So, first of all, you need to pay attention to the profile. This is exactly the basis of frames and sashes. Any profile is a special and complex structure made of plastic and aluminum (maybe steel), the complexity of which can be appreciated only if you cut the profile and see what it has inside. Each profile has several cavities, and between them there are sealed partitions. By the way, it is these cavities that are called window chambers - they allow you to make it warmer due to the void that does not allow air to pass through.

On a note! The more cameras by the window, the warmer the windows will be.

Any profile is produced according to certain standards. In Russia, this is GOST 30673-99. There is also a European version - EN 12608 SR. All profiles can be divided into three types depending on the thickness of the partitions and walls.

Table. Three types of profile.

The metal inside each window is a reinforcement to achieve the required rigidity and strength. It is not visible from the outside, but its importance is great.

When looking at the window, the buyer will see only plastic - PVC. It is artificial, but still a good material, not hazardous to health. It has a low price, does not conduct heat well, is environmentally friendly, dyes well, durable (if it is good), does not let sounds through. In short, ideal for a window system.

On a note! From an aesthetic point of view, PVC is superior to standard wooden windows, which dry out over time and peel off the paint on them.

By the way, the profile width also matters. In another way, and in the slang of professionals, it is called mounting depth. In a conventional window system, it is 0.5-0.8 cm. Moreover, if the width of the frame can be only 0.6 mm, then there will be three cameras inside. There are four, five-chamber, and even six-chamber windows. The wider and more powerful the windows, the higher quality fittings can be used and thicker double-glazed windows. Also, a deeper window usually turns out to be warmer, since there are more chambers in it.

All about double-glazed windows

A double-glazed window is also one of the main elements of any window. This is the same transparent glass that transmits light and allows you to see what is outside the window. It is responsible for a good level of protection against street noise, cold weather, and good illumination.

On a note! The first double-glazed unit appeared about 100 years ago.

The insulating glass unit can easily replace double window frames. It consists of two interconnected sheets of float glass (created using the technology of pouring molten glass mass), and between them there is a special gasket, thanks to which there is a certain space between the glasses. It does not allow any sound or cold to penetrate into the room. The window remains transparent. The glass itself can have a thickness of 3 to 12 mm. For windows in an apartment, a thickness of no more than 5 mm is sufficient.

The described option is a single-chamber double-glazed unit. But if three or more glasses are connected, and there are chambers between them, then there can be 2, 3-chamber double-glazed windows. The more of them, the warmer it will be in the house, but the light will penetrate a little worse. The thickness of the glass unit can be 24, 26 or 32 mm. The choice of type and size will depend on the choice of the window profile.

The glass unit is hermetically sealed, inside it is dry air or a special inert gas (for example, argon). Good windows should not fog up when the temperature drops. Argon windows are more expensive.

Advice! You can choose a package based on the labeling. So, SPD is a two-chamber version, SPO is a single-chamber one.

By the way, glass can have certain characteristics. For example, it can be sprayed, tinted, shock-absorbing, frosted, and so on. Here you need to consider your preferences and budget.

A special metal gasket is installed between the sheets. It allows you to keep the bag accurate in size and shape. Usually the frame is also made of aluminum or steel. This is the source of the appearance of cold bridges. Its width varies from 6 to 24 mm.

Also, the frame is needed to absorb moisture, for this it has perforations, and in the cavity inside there is an absorbent substance that absorbs moisture. This is why the windows do not fog up from the inside.

The double-glazed window must be sealed. Otherwise, it will not keep warm well. Inside, for sealing, a butyl substance is used, which is applied to the area of ​​the sides between the glass and the frame. This sealant does not freeze, is not afraid of temperature fluctuations. Its outer layer is a solid polymer substance such as epoxy or silicone.

Seal selection

The sealant also helps to achieve tightness and good heat retention. It is located around the perimeter of all doors, does not let moisture, noise from the street and cold into the house. So, if possible, it is best to choose a good seal option. It must be strong, durable, elastic, heat-resistant, and not emitting unpleasant odors.

Table. Types of seals.

View	Description
TRE	This is the designation for thermoplastic, the most common option, since it is most often installed during the automatic assembly of the window. It is elastic, easily compressed by the flaps, and seals the joints well. However, frost or hot weather affects it negatively, as the material softens too much or becomes brittle. If the windows have such a seal, it is not recommended to open and close the sashes frequently during extreme conditions. In this case, the material will serve for a very long time. In extreme cases, it is easy to replace it with a new one.
EPDM	Rubber sealant, which is characterized by increased resistance to a number of influences. Costs less than silicone material. Usually installed on more or less expensive windows. Not suitable for self-replacement - everything is too complicated.
Silicone	This is the safest and most durable option. It does not wear out, is not afraid of temperature changes, the effects of a number of other factors. But his price is high, and for self-replacement new seals still need to be found.
Rubber	A good sealant that has a pleasant value. But the soft version of rubber is short-lived and will quickly require replacement, which, by the way, is easy to implement.

Advice! Any seal, no matter how high-quality it is, still needs to be changed after some time. Usually it is easy to do it yourself, without calling the master. You can also try to extend the service life of already installed seals: try to handle the windows carefully, do not use them often in frost or heat, clean the seal twice a year, lubricating it with silicone oil or glycerin. You need to wash only with clean water.

About fittings

The functionality and usability of any window depends on good fittings. By the way, how high-quality it is can often be understood by its appearance. This is not just locks and hinges, but also a system for protecting the window from burglary, sealing and pressing it. Good hardware should be made of high quality steel. Sometimes, elements that are not under severe stress can be made of alloys.

Almost any sash of plastic windows can be opened at different angles or installed on micro-ventilation with just the movement of a handle. No vents are needed to easily ventilate the room, so there is no cluttering of windows with unnecessary elements. But the entire window control system at PVC sashes is rather complicated.

All the fittings of the plastic window surround it in a circle and are well fixed inside and on the sashes in special grooves. All elements must be properly fitted and configured for the window to work well and for a long time. The window fittings include hinge groups, a locking mechanism and a handle, switches for the direction of movement of the sash. Also in the structure there are special combs and ribbons that transmit the force from the human hand to the rest of the elements. Usually, the fittings are installed immediately at the factory, the wizards, when installing the profiles, only adjust it.

Table. Types of window fittings.

Type of	Description
Turning	The usual option is the same as for wooden windows. The plastic frame simply opens and closes along the vertical axis. The hardware can be installed on the left or right side of the frame.
Folding	Such a sash can open 180 degrees along the horizontal axis. It can be opened up or down, depending on the location of the mechanism. Usually, there is also an element to restrict the angle of rotation.
Swing-out	This is the option that most can be found on plastic windows. It allows you to open and partially open a window vertically and horizontally. With such a window, you can use the micro ventilation function. The control is carried out by the sash handle. The most convenient and most complex type of hardware.
Sliding	Such a sash can move along the plane of the window. Sometimes it can be found on the doors of the loggias. There is another option - tilt-and-slide. Such windows can be moved and slightly opened at the top for ventilation.

The sashes of the plastic windows are quite heavy. Only good fittings can withstand such a load and serve the stated period. Its usual version can withstand a load of 50-130 kg. For home - the best option. Good and expensive fittings withstand about 60 thousand opening and closing cycles. As a rule, the manufacturer gives a 10-year warranty on it. The cheaper fittings will withstand up to 10 thousand cycles.

On a note! You can adjust the fittings yourself. All actions are performed using a hex wrench. But without some experience, it is better not to get down to business yourself, but to call a master.

How to choose the right plastic windows

To choose good plastic windows, you need to consider a lot: from who the manufacturer is to the supplier and installer. We will sound the main parameters, what you need to pay attention to when choosing the windows themselves.

First of all, you need to choose a manufacturer. Much, if not all, can depend on this. So, it is better to give preference to proven firms than new unknown brands. The first ones cherish their reputation. However, due to the high competition in the market, even recently existing companies will try to sell good windows, otherwise they simply will not survive with a damaged reputation.

To begin with, it is worth evaluating the appearance of the profile itself, namely, the plastic from which it is made. In appearance, it should be of a uniform color, but to the touch it should not have graininess, the surface should be smooth. Ideally, PVC shouldn't smell unpleasant, but some new windows may still have a proper scent right after installation. If the window smells very strong, then you cannot buy it. It can be treated with protective substances containing cadmium or lead, which are hazardous to health. All connections on frames and sashes must be of high quality, unobtrusive, well-fitted.

Plastic windows are the most popular choice. They are durable, good noise insulation, easy to care for, and their thermal insulation properties are especially important in a continental climate, with hot summers and severe winters.

What plastic windows are best for an apartment? This question will help to answer quality rating of plastic windows, compiled in 2018 based on user reviews from Irecommend and Otzovik sites.

Also, when compiling the window hit parade, such criteria as the durability of the company, the popularity of the products, the quality of service and, of course, the price were taken into account.

The cost of a double-leaf window is from 7,500 rubles.

Opens the rating of the best plastic windows "Panorama" - one of the oldest manufacturers of plastic windows on the Russian market, which has been afloat for over 20 years. Over the years, the St. Petersburg firm has glazed over one and a half million square meters. So far, users are saddened by only one thing - that the company's service is so unobtrusive that it is difficult to get information about possible options.

Cost - from 14,000 rubles.

SOK, or "Samara Window Structures", was founded in 1999. The company does not have its own production, and the profiles are made under the patronage of the German concern Profine.

Prices - from 9 500 rubles.

The Russian branch of the company has established itself with the creation of a new profile system "Favorite Space", which received the "Time for Innovation" prize for high energy efficiency.

Prices - from 8 703 rubles.

Users' complaints are mainly caused by the fittings - their quality leaves much to be desired.

Cost - from 9,000 rubles.

full cycle Russian window company... This means that they make the windows exclusively by themselves, starting from the development of the window and ending with its installation. The advantages of the company are an extensive network of dealer companies with representative offices in more than 80 cities of Russia. Unfortunately, one of the drawbacks is that the quality of both the windows themselves and their installation very much depends on the dealer company. It is worth paying attention to the fact that the head office of the company does not accept complaints about unscrupulous dealers - find out, they say, for yourself.

Turnkey cost - from 9,000 rubles.

The company is the owner of one of the the largest PVC profile production plants in Russia, built under the supervision of Austrian specialists in 2001. Since then, the company has developed many types of profiles, ranging from standard triple to exotic five-chamber. At the moment, seven types of profiles have been created for any client's needs. From the pros - it is easy to bend under windows of any shape. Of the minuses - in some cases they can turn yellow, and the fittings are not the best.

The average cost is 21,900 rubles.

The company has its own production from German components of the highest quality, which allows us to promptly deliver the required orders, up to such unusual ones as windows with protection against falling meteorites(undoubtedly, residents of Chelyabinsk should appreciate them). More traditional systems are thoughtful, robust and durable. Salamander has some of the best quality PVC windows on the market, but there is also a drawback - the price.

3. KBE

Price, on average - 8,700 rubles.

The third place in the ranking of manufacturers of plastic windows is occupied by KBE - its windows have long become one of the the most popular solutions for glazing an apartment... The profile is highly valued by both users and specialists - it was not for nothing that the company's specialists participated in the development of GOST standards for windows in 1997-1999, making KBE windows almost a standard. Users are generally satisfied, considering that KBE are one of the best plastic windows and represent the best price / quality ratio. But, of course, a lot depends on the vendor and installer.

2. REHAU

German company REHAU has been developing and manufacturing PVC window systems since 1969. Over the years, the company has developed many profiles, ranging from the classic three-chamber to the innovative six-chamber. Unfortunately, a lot depends on the vendor and installer.

1. VEKA

Installation cost, on average - 11,500 rubles.

VEKA is considered the best profile for plastic windows on the Russian market. Is another German company that has been on the market for over 45 years.

Nice appearance, variety of profiles, endurance and temperature resistance - qualities that attracted the attention of buyers. But, again, a lot depends on the installer and the quality of the fittings.
