The companies Rehau and Proplex have a good reputation in the modern market of plastic windows in the middle price segment, but what is better - undeniable and respect-inspiring German quality, time-tested, or Russian ergonomics using Austrian technologies - is difficult for the average buyer to understand. Judging by the reviews online, the products of both companies are worthy of attention. A detailed comparison of their designs will help you understand all the intricacies of your choice in order to spend your savings wisely and get the warmest, quietest, strongest, most durable, safe plastic windows possible.

Rehau and Proplex product range

To get a more complete understanding of the strengths and weaknesses of the products of Proplex and Rehau, it is worth starting with a brief historical background and getting to know their product range.

Rehau is a world-famous German concern, operating in Germany since 1948, which released the first profile for PVC windows in 1959. Today its range includes more than 10 types, the most popular of which are the following:

1. Geneo – the latest development, a six-chamber innovation, reinforced in bulk (RAU-FIPRO technology) with a structure that is almost twice as light, but still robust, allowing the use of glass units up to 54 mm. At 86mm depth, the highest heat retention coefficient is 1.05 and sound insulation is 47dB.
2. Intelio – The 80-mm new product for 2017 has six chambers, with a double-glazed window of up to 51 mm, it perfectly retains heat (0.95 m2°C/W) and also protects against noise (47 dB).
3. Brillant-Design – exclusive figured five-chamber design for the embodiment of any design ideas (70 mm), together with a double-glazed window up to 44 mm, excellently saves heat (0.81 m2 ° C / W), and also filters noise (36 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. Production is carried out using unique Austrian technologies. Today Proplex's offers are:

• OUTLINE – a 42 mm two-chamber profile from Proplex, which has a not too high coefficient of resistance to thermal output of 0.405, but which, in combination with a double-glazed window of up to 22 mm, is quite sufficient for a second line of glazing (balconies, loggias, verandas, terraces) or unheated non-residential premises.
• Basis – affordable, reliable 58 mm three-chamber design with decent heat-saving properties (0.64 m2°C/W). Can be used with glass units up to 32 mm for glazing office or production premises, as well as residential buildings located in warm areas or operated primarily in the summer (dachas). Can be combined with anti-burglary fittings.
• Optima – 58 mm budget three-chamber version, which has basic safety, but is warmer (0.70 m2°C/W) due to internal structural features (special arrangement of chambers and reinforcing liner). Designed for use with double-glazed windows up to 34 mm for glazing residential premises, withstands significant temperature fluctuations.
• Comfort – 70mm energy-efficient four-chamber design, suitable for double-glazed windows 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), which has an ideal price-quality ratio. In combination with a double-glazed window 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 option with a heat loss resistance coefficient of 0.82 at 70 mm. Can be used with double-glazed windows up to 42 mm, suitable for glazing buildings in harsh climatic conditions, as well as in high-noise areas.

Advantages 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.

Benefits of Rehau

A comparison of Rehau's offerings with analogues 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 is still standing, which allows us to judge the quality and durability of German products.
2. A wide range of design options allows you to implement any design projects.
3. The line includes models of different price categories - from economy to premium class.
4. Their window frames are as warm as possible (up to 1.05 m2°C/W), quiet (up to 47 dB).
5. Products are constantly being improved; there are innovative models, reinforced in bulk using our own technology, lighter, but at the same time very durable.
6. A high-quality two- or three-circuit two-lobe seal provides the best sealing of windows.
7. Excellent appearance - a snow-white, shiny, very smooth surface that does not turn yellow over time, practically does not become dirty, which reduces maintenance requirements to a minimum.
8. Warranty for 60 years.

Benefits of Proplex

Windows from the Proplex company also have their undeniable advantages:

1. Manufactured 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 the heavy metal lead as part of its profile. It is replaced with 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-matte surface.
4. The products are low maintenance and easy to clean.
5. Good value for money.
6. The versatility of the components, which makes all variants of the profile line compatible with each other.
7. Adaptability to any Russian climatic conditions.
8. Sixty-year warranty.

The main differences between Rehau and Proplex

Windows from the Rehau profile differ significantly from Proplex products, which becomes clear even when superficially comparing competitors’ offers:

1. The range of the German concern is much wider, and over 60 years of active activity it has developed more proprietary and unique manufacturing technologies than the Russian one over 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 double-glazed window is 24-34 mm, heat loss resistance 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 products from a Russian manufacturer is a frame of 70 mm, 4 or 5 chambers, a double-glazed window of 42 mm, a resistance of 0.80 - 0.82, a German one - 80-86 mm, 6 chambers, a double-glazed window of 51-54 mm, a resistance of 0.90 - 1 .05.
4. The Proplex company has a profile in its line with minimal characteristics and cost, designed 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, which can be used to check originality.

Comparison of Rehau and Proplex profiles by characteristics

The main thing 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 decide in favor of one of the manufacturers, you should compare their offers according to the following characteristics:

• wall thickness of window frames;
• number of cameras;
• quantity and quality of sealing circuits;
• type of reinforcement;
• installation width;
• thickness of double-glazed windows;
• appearance;
• service life.

Waterproofing and quality of sealants used

Good waterproofing is a guarantee that the window will not subsequently fog up, accumulate condensation, “grow” mold, or freeze. Waterproofing of PVC windows is carried out using a special sealant arranged in contours, from the Proplex company, for example, in most designs there are two of them. Rehau also basically has two sealing circuits everywhere, except for the latest new product Geneo, in which there are three of them.

An important role is played by the material (mainly EPDM) of the seal, as well as its shape. At Rehau sealing rubber two-petal without internal cavities. It does not collect moisture, does not stretch, does not age, and retains all its properties unchanged while in temperature range from -40 to +120 degrees.

Sound and heat insulation

A plastic window, first of all, should be warm, and secondly, it should well insulate 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 sealant. If we compare the maximum thermal insulation values ​​of Proplex and Rehau plastic windows by class, 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 heat transfer resistance 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.

When it comes to sound insulation, Rehau also holds its own here. In their budget models this figure is 30-35 dB, in more expensive ones – 45-47 dB. Proplex does not specify the sound insulation parameter by type of PVC profile, 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 windows and at least 1.5 mm for large windows. Important nuance– shape of the reinforcing liner. It can be U, G, G-shaped or square. The most durable is the last one, but the G-shaped base is only slightly inferior to the square one.

Basic models of Proplex window profiles are made with U-shaped reinforcement, and premium options are made with square reinforcement. Rehau has a similar situation - budget variations have P-reinforcement, and more expensive ones have G-reinforcement. It would be possible to count the draw, but thanks to its latest development - the RAU-FIPRO fiber reinforcement technology, embodied in Geneo, the German manufacturer takes 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. The strength characteristics remain at the same level, but the weight drops almost by half, which expands the range of applications of such frames and extends the service life of the fittings in them.

Installation depth of PVC profiles

Installation depth is the thickness of the frame in the opening. All properties and technical parameters depend on it. Considering the offers 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 retention coefficients of 0.80-0.85, 0.95, 1.05, the deepest Proplex profile is 70 mm, heat saving index is 0.80-0.82 .

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

Thickness of the outer wall of the profile

The thickness of the outer wall of the window frame largely determines its strength, durability, wear resistance, and resistance to various mechanical damage. World standards and Russian GOST (30673-99) highlight the minimum values ​​of wall thickness with 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, they 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 only has PVC profiles Premium belongs to category A, the rest to B or even C.

Number of air chambers

The main technical characteristic of a 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 ensuring that the rooms are quiet and have a comfortable temperature. The more there are, the higher the energy saving and noise insulation performance.

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

Maximum glass thickness

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

The German concern has proposals:

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

Proplex's profile is significantly behind in this regard, having:

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

Appearance and service life

By appearance Competitors' windows are also different. Rehau designs are as smooth, shiny, and glossy as possible with a bright white surface that does not turn yellow, gray, or fade over time. At the same time, dirt practically does not linger on it, which allows you to replace a thorough washing of the frame with wiping it with a damp cloth only 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-matte, non-shiny surface. It looks stylish, but somewhat dull. But scratches are practically invisible on it. It retains dirt, but washes off quite easily.

As for the service life, both companies guarantee that the profile will retain all its quality characteristics for 60 years.

Comparative table of Rehau and Proplex profiles

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

Manufacturer	Series	Glass unit thickness, mm	Number of air chambers	Thermal protection coefficient, m2C/V 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, Proplex loses (0.80-0.82 versus 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 between Rehau and Proplex

An important factor is the cost of the products. Both manufacturers classify their products in the middle price category. To complete the information, all that remains is to compare the estimated prices for the same windows, for example, double-leaf windows from Proplex and Rehau.

Manufacturer	Name	Price per double-leaf window, rub.

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

During installation, many people have a question about which profile is best for plastic windows.

When choosing, first of all pay attention to the main indicators:

1. Uniformity.
2. Thickness.
3. Number of air chambers.
4. Profile width.

The homogeneity of the product can be assessed “by eye”. Good uniformity indicates a quality product. At the same time, the graininess of the profile system often indicates a fake design.

The thickness of the plastic profile has a significant impact on the thermal conductivity and sound insulation of the product. It must be at least 3 mm. The thickness of the window base directly depends on the number of air chambers.

Profile chambers are small voids filled with air. This structure of these structures contributes to good thermal insulation. Most often, companies produce profile systems with a number of chambers from 2 to 5. But there are seven-chamber designs. They are intended for the far north.

• Double-chamber profiles are mainly used for glazing balconies and loggias. They are considered the most budget-friendly.
• For glazing premises, the most optimal in terms of quality and price are three- and four-chamber products.
• Five-chamber structures are considered the warmest. But they have a significant drawback - a fairly high price.

Also, many experts argue that a large number of air chambers negatively affects the resistance of structures to external factors- sun, wind, rain. Such products may turn yellow and crack. In addition, the more chambers in a product, the softer it becomes. The structure may not support the weight of the glass unit.

The profile width of plastic windows can vary from 60 mm to 90 mm. But the most optimal in terms of price and quality are 70 mm designs. They are no worse in quality than their wide counterparts, but have a much lower price.

It is for this reason that such products are especially popular.

For a manufacturer of window and door structures made of plastic, important indicators when choosing a supplier of components are the quality of the materials needed in production, the corresponding equipment and tools with which employees have to work.

Most of the properties of the finished product are mainly influenced by the characteristics of the PVC profile - the basis for the design of a window or door. Why does the profile determine the reliability and durability of a window?

What types of profiles currently exist? How to choose a PVC profile?

One of the selection criteria for plastic windows is price. The price depends on the class. There are three classes: luxury, economy and standard.

Economy class windows.

Economy class profiles are of the lowest quality; they are usually standard glazing for new buildings and it is advisable to replace them with higher quality ones. Standard class windows have an optimal price-quality ratio. They fully meet European standards.

They are equipped with durable fittings, excellent seals and a beautiful appearance, which has a lot important. Luxury products serve more to emphasize the status of the owner. They do not differ in quality from standard class windows, but are expensive.

Companies producing economy class profiles are: “Veka”, “Montblanc”, “Plafen”. The standard is produced by Trocal, Salamander, Thyssen, Gealan, Rehau and KBE. Luxury brands include Rehau, KBE and Trocal.

The most budget options are products made in China and Turkey.

But they are not intended for the Russian climate; they are cold and thin. Although their cost is quite affordable, they are of little use.

A good budget option is the Novotex brand profile, produced in the Moscow region, and Exprof, manufactured in Tyumen. It is reliable and durable, easy to install, and well suited for the domestic climate.

The highest quality products are from Rehau. They meet all international standards of quality and reliability and have a presentable appearance. The company provides a 40-year warranty on its product. The quality of the KBE brand is not inferior to them, but at the same time its products are 10% cheaper.

The best products today are metal-plastic windows. Profiles from all manufacturers are of high quality. The quality of windows is most influenced by the quality of seals and fittings.

The choice of plastic windows, of course, largely depends on financial opportunities buyer. If possible, it is better not to save on windows, then you can buy quality products that will last for many years.

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

By installing metal-plastic windows in your home, you can be sure that even harsh winter Warmth will reign in the house, since such windows are distinguished by their high level of thermal insulation.

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

Also, metal-plastic windows are easy to maintain - you just need to remember to wash them with detergent from time to time. Wide choose shapes, colors, texture elements and design methods allows you to bring to life the most unusual design ideas, and just give the room a cozy and elegant look.

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

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

The choice of fittings is important point, when manufacturing and equipping a window, strange as it may seem at first glance. In order to make the right choice, you must:

• Familiarize yourself with the types and purposes of fittings.
• Choose the most reliable manufacturer that produces high-quality products (based on user reviews).
• Determine the needs of various types of fittings and their technical characteristics.
• Determine the relationship between price and service life of the products.

Equipment and type of accessories for each specific window is individual, which is determined by its design and the method of opening the doors (right or left, sliding or swing type, blind or tilt-and-turn design, etc.).

The standard package of a window made from PVC profile includes the following elements:

• Window hinges (bottom and top).
• Compensator.
• Protective mechanism (fuse) against slamming.
• Devices for lifting window sash.
• Retainers.
• Brackets.
• Tilt-and-turn mechanism.

In addition to the products listed above, the kit may include window sash rotation limiters, slot ventilators, mosquito nets and locks that ensure the window is closed from the inside.

In the manufacture of fittings, various metals and their alloys are used, which characterizes their strength and reliability. On the outside, the fittings are coated with anti-corrosion paints and varnishes.

The criteria for choosing accessories are:

• Wear resistance.
• Resistance to external influences.
• Availability of warranty period and certificate of conformity.
• Appearance (aesthetics) and ease of use.

When the user is faced with a question related to the choice of plastic windows, in addition to the technical components that determine the characteristics of the window (the type of profile and the material from which it is made, the type of double-glazed window, the availability and quality of seals and fittings), an organizational component also appears - which manufacturer’s windows to choose.

A large number of large and small companies of various forms of ownership operate on the domestic market for such products. However, the main manufacturers of metal-plastic profiles are only a few companies, whose products have their own inherent advantages and disadvantages; below are the most popular of them.

The KVE company operates in different countries and different continents. In Russia, this company has representative offices in many regions; the production of metal-plastic profiles is located in the Moscow region. The representative of the company in Russia is ZAO Profine RUS (Moscow).

The advantages of KVE products are:

• High rates of heat and sound insulation.
• Wide operating temperature range.
• Availability of a ventilation system that ensures that glass units do not fog up.

The disadvantages include:

• High price.
• White plastic may turn yellow when exposed to sunlight.

Rehau, Germany

The Rehau company operates in different industries and in different countries around the world. One of the areas of activity is the production of translucent structures, including metal-plastic profiles.

The company's central office for Eastern Europe located in Moscow, and representative offices in the following cities: St. Petersburg, Voronezh, Nizhny Novgorod, Samara, Yekaterinburg, Rostov-on-Don, Novosibirsk, Krasnodar, Irkutsk, Khabarovsk and Simferopol.

The advantages of Rehau products are:

• Strength.
• A large assortment various types profile.
• Good performance in terms of heat and sound insulation.
• Frost resistance of products.

• High price.
• Limited height of sashes on manufactured products.

"PROPLEX", Russia

"PROPLEX" is one of the first domestic enterprises that began working in the market of metal-plastic windows through the full cycle of their production.

The advantages of products manufactured at this enterprise are:

• Relatively low cost.
• Long service life.
• They are adapted to operating conditions in Russia.

1. The embodiment of German quality and precision is window designs from Rehau. Its products belong to the elite segment and may seem unreasonably expensive to the average person. However, do not forget that all designs here undergo thorough technical control, which means they are of impeccable quality. Rehau window profiles are offered different color and shapes, but will always be distinguished by excellent thermal insulation due to a multi-chamber profile and several sealing contours. The company is also constantly introducing new ergonomic designs.
2. Veko can also boast of German quality products. Such window profiles are characterized by an “ideal appearance” - a snow-white and even surface, long-term color retention. In the profiles of this trademark exclusively closed reinforcement is used. The company’s offerings include more than one and a half thousand different different profiles and they are all durable, strong, and easy to maintain. Product quality is ensured the strictest control from the moment raw materials arrive.

From Germany and the company KBE. today successfully maintaining leadership in its segment. Polyvinyl chloride for such profiles is made from natural raw materials - oil and table salt. The resulting PVC is chemically neutral, that is, it does not react to contact with air - this is what ensures its environmental friendliness, durability and safety. The company puts technology improvement at the forefront and offers consumers budget 3-chamber and luxury 5-chamber models. Among the latest developments is green line technology, which eliminates lead, which is unsafe for nature, from the profile composition. The profile, made using new technology, is durable and resistant to external aggressive environments and stands up well to bad weather. You can also choose attractive options with a durable matte sheen. The company's production uses the best quality system - the fact that the product is of high quality and complies with European standards is evidenced by many awards. By the way, KBE profiles are considered one of the most durable (they have a service life of 40 years) and can be used in the temperature range of -65 - 80°C.

PVC profiles from the Russian company Novotex are a budget four-chamber option. Many production technologies are borrowed from the KBE company - as a result, the products are not inferior in quality, practicality and durability. The only downside is that there is not such a large selection. But this is the most inexpensive option in the segment of high-quality window profiles.

Which window profile is better?

PVC windows are convenient, beautiful and practical solution, as well as justified necessity. Today it is hardly possible to find a high-quality alternative that will surpass such windows in terms of body and sound insulation characteristics.

To install really good windows, it is important to know which profile to choose.

Typically, all products are compared according to the following characteristics:

• design and color;
• number of cameras;
• thickness;
• thermal conductivity;
• popularity of the manufacturer;
• what fittings are installed;

Before choosing plastic windows, you should acquire some knowledge in this specific industry. One of the main criteria PVC selection windows is a brand of plastic profile. Even one manufacturing company has profile systems that differ in both class and price. In order not to overpay extra money, but at the same time purchase a system that has optimal technical characteristics, you should approach its choice very thoroughly.

• Profile thickness and width
• Number of cameras
• Presence/absence of reinforcement

The issue of installation depth (width) of the profile is one of the main ones considered when choosing PVC windows. Most often, manufacturers offer designs with an indicator of 58 and 70 mm. Considered classic window unit by 58 mm. Structures with an installation depth of 58 mm are mounted in residential buildings and industrial buildings. These systems make it possible to effectively solve many problems in the field of architectural design; they are also called universal.

The 70 mm profile system is used in the manufacture of windows with increased thermophysical characteristics. In such structures it is possible to install double-glazed windows with improved sound and heat insulation, having a larger width and different filling options. However, a width of 70 mm is not the limit. The modern window market offers profile systems of 80, 90 and 104 mm. At the same time, the width of the double-glazed windows can also be increased. This approach is used in houses with passive heating.

Chambering is the number of chambers inside a profile system, formed by installing vertical partitions separated from the reinforcing profile. Each camera has its own purpose. The first is responsible for removing accumulated moisture (water leaves through special channels in the PVC system). The second (central) chamber is arranged for additional fixation of window fittings and creating an effective air thermal layer.

An increase in the number of cameras is accompanied by an increase in the installation depth of the profile. If the number of chambers increases without changing the installation width, then this will not have any effect on the thermal physics of the window. Most likely, this is just an advertising, marketing gimmick. If the window is 58 mm wide, three cameras will be enough, but a 70 mm profile should have 4 or more cameras, a 90 mm system should have 6 cameras.

However, in pursuit of cameras and millimeters, you can forget about how all this will affect the safety of the window structure. Some companies try not to mention that the economical profiles they produce have a rather thin outer wall - class “B” profiles. Such a flaw, invisible at first glance, can significantly complicate the life of the owner of a window system.

The danger of class “B” windows lies in the fact that a thinner outer wall provokes blowing through the window, and frequent adjustments contribute to rapid failure of the fittings. In addition, the shape stability and geometry of the window in comparison with class “A” systems is much worse, which leads to sagging of the sashes and even complete breakdown of the system.

Deciding which better profile for windows, do not forget to specify what the reinforcing element is made of. It is located in the center of the profile. You can see it only on the cut.

The main task of the reinforcing profile is to impart the required rigidity to the structure. This element must be galvanized and have sufficient width. Remember, the wider the reinforcing component, the stronger the window.

When choosing PVC windows, you should pay attention to two criteria - noise and heat insulation. For example, if your windows face a busy highway, you should install at least a four-chamber profile; if there are strong winds in your area of ​​residence, a 5-chamber profile will ensure high-quality thermal insulation.

If the installation of windows is carried out on the upper floors, where street noise is practically inaudible, but there are high wind loads, the 5-chamber profile will not only reliably protect against wind and cold, but will also provide the required structural rigidity. If your house is located in a calm, quiet place, you should not overpay for PVC; it will be enough to purchase a 3-chamber version.

Large structures experience high loads. They must withstand the weight of heavy double-glazed windows and gusts of wind. Since not all buyers know when ordering large plastic windows which profile is best to choose, they may subsequently encounter deformation of large structures. To avoid this, you need to follow several recommendations:

• give preference to a multi-chamber A-class profile with an external wall thickness of 3 mm and an installation depth of 80-86 mm;
• order closed reinforcement with steel liners with a wall thickness of 1.5 mm;

Based on these two points, you can choose large windows that will last for many years and will not cause any trouble.

Windows made from PVC profiles mean convenience, an attractive and practical appearance, and also a justified necessity. It is hardly possible to find a worthy alternative, taking into account the heat and sound insulation characteristics of the products. However, in order for you to get truly high-quality window designs, you need to understand which window profile is better.

They should be compared according to such parameters and characteristics as:

• thickness;
• number of cameras;
• design and color scheme;
• level of thermal conductivity;
• type and quality of fittings;
• popularity of the manufacturer.

In this section, we invite you to look at a gallery of photographs on the topic of our article “Which window profile is best to choose.” All photos are clickable.

In the manufacture of windows, various types of profiles can be used, both in terms of its design and the material from which it is made.

This is a natural and environmentally friendly material that has always been widely used in the manufacture of windows.

Currently, due to the advent of new technologies and the high cost of natural raw materials, it is used less widely.

Wood species such as teak, larch, oak, Canadian Hemlock and teak wood are used for the manufacture of windows according to individual orders and in the construction of premium housing.

Coniferous trees are used in the manufacture of cheaper structures, but, nevertheless, they are still more expensive than products made from various types of plastic and some types of composites.

Pure aluminum is not a very good material in terms of its use for the manufacture of window blocks. The reason for this is its high thermal conductivity and low elasticity.

In this regard, aluminum faucets are rarely used in their pure form for these structural elements, but in combination with polyvinyl chloride materials they are an excellent component of such products.

Fiber composites are fiberglass made from a reinforced profile and a fiberglass composite.

This material has good heat-insulating properties and strength indicators that exceed those of wood and metal, respectively.

The disadvantage that determines its rather narrow distribution is that under the influence of the external environment (precipitation, sunlight, etc.), this material delaminates.

When using a carbon fiber composite, this disadvantage missing, but in this case the product is very expensive.

The use of aluminum, which serves as a frame in the manufacture of window profiles and plastic, made it possible to create a wonderful tandem of materials, which made it possible to combine their advantages and create a durable product with good thermal insulation properties.

Metal-plastic profiles are currently widely used in the manufacture of window blocks of various designs.

Windows made from PVC profiles mean convenience, an attractive and practical appearance, and also a justified necessity. It is hardly possible to find a worthy alternative, taking into account the heat and sound insulation characteristics of the products. However, in order for you to get truly high-quality window designs, you need to understand which window profile is better.

• thickness;
• number of cameras;
• design and color scheme;
• level of thermal conductivity;
• type and quality of fittings;
• popularity of the manufacturer.

Window profiles in metal-plastic structures are used for the manufacture of frames and sashes.

It is a system with cavities and partitions inside - it turns out that separate chambers with air appear inside it. But you should also take into account the number of air chambers in the profile - it varies from 1 to 8 (for our microclimate, 2-5 are recommended). The heat-saving properties of the entire window depend on the number of chambers.

• class A - thickness 3 mm;
• B - 2.5 mm;
• C - less than 2.5 mm.

A plastic window profile is necessarily reinforced, for which a steel core is used. The core guarantees the window strength and rigidity. There are 2 core designs - U-shaped and square. The latter, closed design is more reliable, but also more expensive.

It is also important to choose a quality seal - the best option rubber will become, retaining its elasticity for a long time (at least 5 years). This material guarantees long-term preservation of the tightness of the structure.

Market Review

Products from several companies may meet all these requirements. Therefore, many people wonder which company’s profile is best to choose for plastic windows.

There are a huge number of manufacturers of metal-plastic structures on the modern market. But experts advise choosing well-known, trusted companies. “Promoted” companies seriously monitor the quality of their products. When choosing their products, you will definitely be sure that you have avoided a low-quality counterfeit.

Choose a trusted manufacturer

Based on quality and price, you can create a conditional rating of plastic profiles for windows.

The most in great demand in the modern market of metal-plastic structures they use the profile of the KBE company. This German company was one of the first to appear on the CIS market. She presents both budget options and more expensive ones. KBE products are environmentally friendly and are recommended for installation in kindergartens and medical institutions. KBE structures are considered one of the most durable. Their service life is 40-50 years.

Rehau profiles are very popular. This is a quality German company. The designs of this manufacturer use high-quality environmentally friendly materials. Rehau also added a climate control function and a locking system to their designs, which prevents entry into the house through the window. The only drawback of Rehau products is the small height of the sash.

The well-known company Veka has been losing ground a little lately. This is due to outdated design models compared to competitors. But the most important disadvantage of this manufacturer is the use of lead in the manufacture of structures. This radioactive element has a very negative effect on the human body, causing various diseases.

Lovers of interesting design solutions will appreciate Aluplast designs. This manufacturer presents more than 40 decor variations. Aluplast is constantly developing various innovations to better meet consumer requirements.

The disadvantage of these systems is their tightness. On the one hand, this contributes to good thermal insulation. On the other hand, such tightness contributes to the accumulation of vapors in the room and the room must be constantly ventilated.

The first company to start producing plastic windows, Trocal, is also not very popular in the CIS countries. The manufacturer’s designs are quite durable, but do not have any special distinctive features from competitors.

We select a high-quality PVC profile

Window profiles in metal-plastic structures are used for the manufacture of frames and sashes. It is a system with cavities and partitions inside - it turns out that separate chambers with air appear inside it. But you should also take into account the number of air chambers in the profile - it varies from 1 to 8 (for our microclimate, 2-5 are recommended). The heat-saving properties of the entire window depend on the number of chambers.

Single- and double-chamber double-glazed windows

• class A - thickness 3 mm;
• B - 2.5 mm;
• C - less than 2.5 mm.

The thickness of the outer wall is an indicator of the profile class

Plastic window profiles are necessarily reinforced. What is the steel core used for? The core guarantees the window strength and rigidity. There are 2 core designs - U-shaped and square. The latter, closed design is more reliable, but also more expensive.

Read our detailed review of seals for plastic windows. How to distinguish them and not make a mistake when choosing.

And you will learn from this material how to lubricate and care for plastic windows so that they last as long as possible.

Plastic window profile design

The window profile can also be colored - this is achieved by gluing a special durable film onto the profile. The use of film (simulating wood of various species, etc.) will lead to an overall increase in the cost of the structure by 25-30%, but sometimes this is the only correct solution that allows you to fit the window structure into the existing interior.

There is a wide range of window profile colors

Products from various world-famous manufacturers are patented designs with their own characteristics. But the profiles will have the same general features. The main thing is that the product has a quality certificate. A hygienic certificate is also important, confirming the safety of the product and allowing its use in residential premises.

By the way, laser marking is applied to a high-quality profile. demonstrating the time of manufacture of the product and the country of origin.

It is also important that high-quality profiles can vary significantly in price. The cost of products depends on the raw materials used, the type of production process, design features and the brand that produces the windows. Three types can be distinguished:

• economy - the most budget options with “average” characteristics and little design and technical variability;
• standard - above average characteristics, you can choose the appropriate design, type, and so on;
• elite - impeccable quality, many innovative technologies, but also the highest price.

Frames and sashes are made from window profiles. This is a kind of system with air spaces as well as partitions. Here the first question arises: how many cameras should there be in a profile? For our climatic conditions, it is recommended to pay attention to 2-5 cameras. It so happens that the heat-saving properties of the window directly depend on the number of these elements inside the profile.

The outer wall thickness of PVC profile is classified as follows:

• A – thickness is 3 mm;
• B – 2.5 mm;
• C – less than 2.5 mm.

Any plastic profile must be reinforced with a steel core. This solution allows us to achieve a good level of rigidity and strength. Of the two designs - square and U-shaped - it is better to choose the first option due to its greater reliability. However, the price of the window will be a little more expensive.

When the question arises regarding the choice of sealant, pay attention to rubber. This material will serve you for more than 5 years and will retain its elasticity. Rubber ensures the tightness of the entire structure.

A good profile must be equipped with equally high-quality fittings. This includes hinges, brackets, handles and other elements that ensure the opening/closing of the window. All parts must correspond to the dimensions of the window and reliably support the weight of the opening sash.

Any plastic window can have any profile color - a strong and durable film is glued to it. Thus, it is possible to obtain imitation wood and so on. As a result, the price of such a design will increase by 30%. But if you need to fit windows into the existing interior, and a simple white color is not suitable, a profile with glued film is the only way out of the situation.

Profiles from popular manufacturers have their own features, which are developed according to their own patents. However, in practice the general features are quite similar. The only thing you should pay close attention to is the presence of a quality certificate. In addition to this document, it is important to have a hygiene certificate - this is necessary so that you can safely use windows in residential premises. You cannot order windows without such a document!

High-quality material has laser markings that indicate the country of origin and time of manufacture. Good window profiles can vary in price, and quite a lot. Pricing depends on the raw materials used in manufacturing, as well as the type of production process, brand and design features.

If we summarize all the indicators, we can distinguish three types:

• economical - the simplest products with average characteristics and limited technical variability;
• standard – improved characteristics. It is possible to choose the design, type and other properties;
• elite - the best quality, a wide range of innovative technologies and a fairly high price.

What should a modern PVC window profile be like?

Today, the main European quality standard for PVC window profiles is RAL-GZ 716/1.

It defines the following parameters of polyvinyl chloride products:

• class A: external walls must reach 2.8 mm in thickness, internal walls - 2.5 mm;
• class B: the thickness of the external walls should not be less than 2.5 mm, internal - 2 mm;
• class C: external and internal walls can have almost any wall thickness.

Naturally, it is better to give preference to profiles of the first two classes, which have excellent parameters.

But if class C products are used, then only for installation in technical rooms or for temporary service.

At this stage the window is almost finished in appearance and functionality, the only thing missing until it is fully prepared is the clear glass which is installed on the next stage of the conveyor belt.

Plastic windows: which profile to choose?

Profile class

The set of industrial standards RAL-GZ 716/1, which is relevant for EU countries, provides for 3 classes of window profiles - A, B, C. This division and the requirement to mark systems protected buyers from purchasing products that do not meet their requirements. Systems of different classes differ from each other according to 2 main characteristics:

• composition of raw materials for co-extrusion of profiles;
• thickness of external and internal walls.

The service life, reliability and aesthetic appearance of windows depend on the quality of raw materials and the thickness of the plastic.

The width (installation depth) and the number of chambers affect both the stability of the windows and their heat-saving properties. The greater these parameters, the warmer and stiffer the structures assembled from such a profile. Today, the market offers systems that have from 3 to 8 cameras and installation depths from 58 to 127 mm.

A-class - external walls must exceed 2.8 mm, and internal jumpers must be at least 2.5 mm; B-class - the minimum allowed by the standard for external walls is 2.5 mm, and for internal walls - 2 mm.

The thickness of the profile walls also determines the level of noise absorption of window structures and their energy efficiency.

Reinforcement

Plastic windows without reinforcement can become deformed due to the load from large sashes that are heavy. This process entails depressurization of the structure. To prevent this, special metal inserts are inserted into the internal chambers. They differ from each other in cross-section and wall thickness, which should not be less than 1.2 mm. Their optimal thickness is 1.5 mm.

Today, leading European manufacturers of premium systems are actively replacing metal liners with elements made of durable fiberglass. Without sacrificing strength, they reduce the weight of windows and increase their energy efficiency.

Environmental friendliness of PVC

When producing profiles, various stabilizers and modifiers are added to pure PVC to improve the strength, color and heat resistance of the products. Previously, many manufacturers used additives that contained harmful lead. Although studies conducted in Europe partially dispelled buyers' fears and proved that PVC is harmless to health, fear of this metal remains.

The biggest concern is not the certified products, but the profiles made in artisanal conditions. Such products may contain lead and other substances harmful to health. In order not to order windows from such components, you need to require a certificate of compliance with environmental safety requirements.

Different profiles have different maximum thicknesses of double-glazed windows that can be installed in windows. Typically, this parameter directly depends on the installation depth of the system. The larger it is, the thicker the double-glazed windows can be used to complete the windows.

With the advent of selective glass, there was no longer a need to use thick double-glazed windows to retain heat. Three-chamber models are recommended for use only in northern regions or in noisy areas (to increase the level of sound absorption of windows).

Modern profile systems have 2 or 3 sealing circuits. The tightness class of structures depends on their number. If the windows are planned to be used in conditions of high wind loads or at very low temperatures, it is advisable to give preference to profiles with 3 sealing contours.

This parameter is rarely paid attention to, although it is important. The depth of the rebate affects the likelihood of condensation occurring around the perimeter of the double-glazed windows. For profiles with a short landing distance, the glass around the spacer quickly cools in winter. This leads to the formation of condensation. To reduce the risk of it falling out, it is recommended to give preference to systems with a rebate depth of at least 20-21 mm.

Lamination

Most window companies additionally provide plastic lamination services. Its essence is to apply a polymer film with a plain or tree-like decor on one or two sides of the profile. If you plan to install colored windows at a facility, it is recommended to find out exactly what coatings the manufacturer offers.

To figure out which profile to choose for PVC windows with high energy efficiency, you first need to understand how heat is retained indoors. Fittings, double-glazed windows and, of course, the profile system are responsible for this process. Most heat is lost through the translucent filling, so you need to take care of this part of the window structure first. However, without taking into account the characteristics of the profiles, it is impossible to complete this task, since there are 2 ways to increase the energy efficiency of windows:

1. Install thick double-glazed windows– such integration is only possible in structures assembled from profiles with an installation depth of 70 mm or more. The number of internal cameras in such windows is usually 5-6 pieces.
2. Install single-chamber double-glazed windows with selective coating– such installation does not require a powerful profile. However, the use of 3-chamber systems with an installation depth of 58-60 mm will lead to heat leakage in the area of ​​the sashes and frame, so a 5-chamber profile would be the best option.

To produce warm windows with any type of double-glazed windows, it is necessary to use profiles with increased installation depth for assembly. Otherwise, the energy efficiency of the structures will be insufficient to maintain a comfortable temperature in the interior.

A window is a necessary element of any room. It is a source of light and fresh air, through it you can observe the activities taking place outside the building. However, it is through the window that more heat escapes in winter and more noise comes from the street.

Durability, thermal conductivity, sound insulation and other characteristics of a window depend on many factors, one of which is the quality of the window profile. This article will help you figure out which plastic window profile is better.

A window profile or window profile is a supporting structure that is built into the window opening. Its main purpose is to fit tightly to the wall of the room and hold the double-glazed windows. The structure formed by window profiles may have various configurations, but usually this is a window frame and vents (transoms).

The strength, durability, convenience and efficiency of a window depend entirely on the quality of the profile. Therefore, the main requirements for the material from which the profile is made are strength, resistance to temperature changes, resistance to sunlight and moisture, low temperature expansion and movement, and low thermal conductivity.

An important factor when choosing a window profile is its appearance. After all, the window is one of the most significant elements of the interior. Therefore, the profile must retain its external characteristics (color, structure, brightness) for a long time. Profiles that do not require additional maintenance, for example, metal-plastic profiles, have a good advantage.

There are many types of window profiles. They are classified according to various criteria, each type has individual technical characteristics, advantages and disadvantages.

The main division of window profiles is made according to the material of manufacture:

1. Wooden profiles for windows are the oldest representatives of their kind, despite this they remain leaders among their peers in terms of efficiency.
2. Fiberglass profiles are the most effective in terms of technical characteristics, but their main drawback is their fragility.
3. Aluminum window profiles have the most attractive appearance, but otherwise they are inferior in all respects - cold, short-lived and low-strength.
4. A metal-plastic profile (PVC) consists of aluminum coated with plastic. This design has excellent technical characteristics - low thermal conductivity, strength, resistance to temperature changes and other natural influences. Well-known plastic windows are made from metal-plastic profiles.

• windows for temperate climates;
• windows for harsh climates;
• windows for harsh climates.

The metal-plastic profile consists of several chambers. With an increase in their number, the technical characteristics of the window also improve - thermal conductivity and strength.

There are three-, four-, five- and six-chamber metal-plastic profiles. However, the most common is the three-chamber profile, since its technical characteristics are quite sufficient to ensure comfortable indoor conditions over a long period of operation.

Each chamber in a metal-plastic profile has its own purpose: fastening fittings, draining condensate, etc.

• 58-70 mm;
• 70-90 mm;
• 90 mm or more.

1. Rehau – German quality. Window designs belong to the elite level, and such products may seem very expensive to the average buyer. But this manufacturer carefully monitors quality through many technical controls. Any colors and shapes of Rehau have the highest level of thermal insulation (multi-chamber design and several layers of sealing). The manufacturer regularly releases updated ergonomic designs.
2. Veko is also a German profile with an ideal appearance. Long-term color retention, surface evenness, durability are the main advantages of the profile. The design always uses closed reinforcement. The products include more than 1,500 profiles that are reliable and easy to clean.
3. KBE (Germany) - the company has successfully occupied its share of the market in the window profile sales segment. PVC is made from natural raw materials - table salt and oil. KBE products are chemically neutral and therefore do not react in any way to contact with air. Environmental friendliness, safety and durability are the main qualities of this manufacturer’s profile. The main activity of the company is technology improvement. Among the available options you will find 3-chamber budget and 5-chamber luxury models.

Advantages of each class

Although the wall thickness of the profiles of these two classes differs slightly, their consumer characteristics are very different. When testing, class A products are ahead of class B products in many respects. If we talk about compliance with the DIN EN 12608 standard, the reduction in strength of a profile with reduced wall thickness is 25%, and the resistance to tearing out of self-tapping screws is also reduced by 20%, 15% the ability to maintain its shape decreases.

Therefore, PVC windows, the construction of which uses a class B profile, do not last as long as products of the first category.

And yet, the class B profile has an important advantage - a more affordable cost.

Almost all manufacturers of profiles for PVC windows, whose products are represented on the markets of post-Soviet countries, offer products of classes A and B. Only the manufacturer VEKA offers consumers only products of the highest category.

Thanks to various types profiles, their manufacturers try to satisfy the various wishes of their customers.

Therefore, each consumer can choose the most suitable product.

Class A profile will be the best option in the following cases:

• when the client is used to receiving only the best and is not ready to compromise on quality;
• large cash costs are not a problem.

Class B profile may be preferred in the following cases:

• there is no need for a large margin of safety and thermal insulation indicators, which are inherent in products of the highest category.

  This choice is fully justified for installing plastic windows in non-residential premises, buildings with seasonal residence or industrial facilities;

• The quality of a window structure is determined not only by the profile class.

  For example, you can achieve increased strength using reinforcement. And installing a double-glazed window with several chambers will help improve heat-saving parameters.

Russian legislation allows glazing of residential properties using profiles of classes A and B.

Thanks to this, the consumer can make his choice taking into account the purposes and purpose for which the plastic window is purchased. The financial side of the issue is also important. Having carefully weighed all the reasons, you can choose the most suitable type of profile.

Plastic windows firmly occupy a leading position. They are distinguished by a high level of heat and sound insulation, and also provide the opportunity to choose fittings, window opening method and profile color. You can also choose a double-glazed window with required quantity cameras But few people think that it is the window profile that ensures the strength and durability of the entire structure. In this article we compare plastic window profiles with different characteristics and manufacturers.

General information about the profile of plastic windows

On average, the profile thickness of plastic windows varies from 58 mm to 86 mm, but some companies produce products up to 127 mm wide.

Its interior is hollow, but is divided by bridges that create several air chambers. A special technical calculation determines their dimensions and location. The wider the profile, the greater the number of chambers in it, increasing the heat-saving properties. Another characteristic of the profile system is the filling width, which determines what type of double-glazed windows can be installed in the profile. They come in single- or double-chamber types, the width of the glass in a standard double-glazed window is 4 mm (grade M1).

Each cavity has its own purpose:

• for water drainage;
• fastening accessories;
• responsible for strength, etc.

The color of the profile can be varied; painting is applied in several ways:

• coextrusion method - multilayer films create a kind of barrier that allows the product to withstand dynamic loads without damage;

• lamination - with imitation texture, for example, marble or wood;
• monochromatic coloring.

Characteristics of PVC profiles for plastic windows

Material

• This product is made from a type of plastic - white polyvinyl chloride.
• The material is highly resistant to chemical attack by alkalis, solvents, acids and mineral oils.
• It is harmless to humans and the environment.

• Due to its distinctive properties, polyvinyl chloride makes it possible to produce frames for double-glazed windows not only in rectangular or square shapes, but also in the form of arches, triangles, circles, and so on. Thus, giving absolutely any simple or complex configuration to the window, allowing even the most non-standard idea of ​​designers and architects to become a reality.

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 a profile is 3, the maximum is 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. It should be noted right away that 3- and 5-chamber profiles are popular.

Reinforcement

To provide rigidity, the profile is additionally reinforced. The metal frame provides the necessary structural strength and reliability during operation of the window. Galvanized steel is used to reinforce the profile, so it does not deform due to temperature changes or other environmental influences.

• L-shaped type of reinforcement - metal insert installed along two walls;
• U-shaped type of reinforcement, where metal strengthens three walls;
• Closed type of reinforcement - a metal insert is located along four walls.

For window structures that have double-glazed windows up to 1900 mm in height, a U-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 determines whether it belongs to a certain class:

• Class A - the thickness of the profile walls must be at least 3 mm;
• Class B - profile where the wall thickness is from 2.5 mm;
• Class C - non-standardized wall thickness.

As a result, the width of the profile of plastic windows directly depends on its class. The higher it is, the correspondingly wider the profile.

Comparison of manufacturers of plastic window profiles

On Russian market Many people present their products, both domestic and foreign manufacturers. The leading positions in the ranking of profiles for plastic windows are occupied by the following companies:

• Germany - REHAU, VEKA, KBE, SALAMANDER, SCHUCO, KOMMERLING;

You can also compare the characteristics of plastic window profiles using the tables below.

Profiles of the German company KBE

It is believed that German profiles of plastic windows are superior to the products of other manufacturers in terms of quality, whiteness of color, and technical characteristics. They do not lose their properties even over a long service life and can withstand almost any dynamic loads and significant temperature changes (from -50°C to +50°C).

The KBE company produces and supplies 2 types of the most popular profiles: KBE Etalon and KBE Expert.

KBE Etalon - three-chamber profile

• The installation width is 58 mm;
• width of front walls - 3 mm;
• the thickness of the glass unit can be up to 34 mm;
• 3 chambers in the frame, sashes, impost (horizontal and vertical window bars);
• can be used in harsh conditions (-60°C);
• service life - 40 years;

Advantages:

• 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, which exceeds the existing GOST requirements by 5 (!) times, which guarantees the complete absence of dust and drafts in the room;
• two sealed sealing gaskets provide excellent sound insulation (up to 46 dB). The profile is additionally equipped with horizontal lintels, thereby increasing the strength of the lock when closing the window;
• The KBE profile has stiffening ribs that provide additional strength to the window structure. Also, special stops can increase rigidity, with the help of which the precise location of the reinforcing metal insert is achieved.

KBE Expert - five-chamber profile

• Installation width is 70 mm;
• width of front walls - 3 mm;
• glass unit thickness is up to 42 mm;
• 5 chambers in the frame and sashes, 3 or 4 in the impost (horizontal and vertical window bars);
• Suitable for use in harsh conditions (-60°C);
• sealing contours correspond to class A;
• service life - 40 years;
• Environmentally friendly materials are used in production and do not contain lead.

Advantages:

• The five-chamber structure allows for better thermal insulation values; this profile is capable of retaining heat 20% more than typical three-chamber systems. You can achieve excellent sound insulation by installing wide double-glazed windows with a 70 mm profile;
• The 13 mm groove of the profile allows you to install anti-burglary fittings, thereby ensuring the security of the room;
• the KBE Expert profile has additional horizontal jumpers, thanks to which the handles and hinges will be securely fastened;
• When installed, the mounting seam becomes approximately 20% wider, in turn allowing for additional insulation.

Estimated cost of windows from KBE profile

An important factor when choosing a particular double-glazed window is its price. It is often decisive, but high quality German window profiles cannot be cheap. Below is the approximate market value in Russia.

• On average, a single-chamber double-hung window with dimensions of 140x130 cm, in which one sash is fixed and the other is tilt-and-turn, will cost:
  • from a 58 mm profile from RUB 7,500,
  • from 70 mm - from 10,000 rub.

• Price of a two-chamber three-leaf window measuring 140x203 cm, in which the first sash is rotary, the central one is blind type, the third one is tilt-and-turn and will range from:
  • from 58 mm profile 13,000 rubles;
  • from 70 mm 14500 rub. and higher.

• When purchasing a balcony block with an opening door measuring 210x67 cm and a blind window - 140x136 cm, you will have to pay at least:
  • from a 58 mm profile 11,000 rubles;
  • from 70 mm from 13,000 rub.

What to look for when choosing a plastic profile with double-glazed windows

In order to determine what profile thickness is needed, you should have basic knowledge about the double-glazed window, because up to 70% of heat losses occur through it.

This transparent element consists of 2 or more glasses that are tightly connected to the frame. A chamber (air gap) is formed between them, filled with rarefied air or an inert gas, such as argon or krypton. This kind of filling is used in the production of energy-saving double-glazed windows.

A single-chamber double-glazed window is a design of 2 glasses of 4 mm each and an air gap of 16 mm, in abbreviated form it is designated 4-16-4. Thus, its installation width is 24 mm. The design, equal to 36 mm, is obtained from a two-chamber double-glazed window, which consists of 3 glasses of 4 mm each and 2 layers of 10 mm each - 4-10-4-10-4.

Consequently, an appropriate profile is selected for the required double-glazed window. For example, the optimal solution for an ordinary apartment or house would be a 5-chamber profile with a 70 mm installation width and a 30 mm double-glazed unit, where a heat-reflecting coating should be applied to one glass.

If the windows face the north side and there is a busy road nearby, then in this case it will be suitable next option: 5-chamber profile with a depth of 86 mm, complemented by a 32 mm double-glazed window with a protective noise-insulating film.

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

For simple insulation of a balcony, a 60 mm 3-chamber profile and a 30 mm single-chamber double-glazed window are suitable.

But it’s not enough just to choose the optimal PVC profile and double-glazed window. It is equally important to entrust the installation of the finished window to professionals. Otherwise, no matter how expensive the design, poor-quality installation will cancel all its high characteristics.

No one will refute the truth that in our latitudes, good windows in an apartment or house are important. Many buyers are misled by the apparent simplicity of the designs. It is believed that there is nothing particularly complicated about plastic windows - a regular frame, glass, a simple locking mechanism. There are differences between window designs and are often quite significant.

There are significant differences between windows from different manufacturers. In the last 2 decades, PVC structures have become popular. Profiles made of polyvinyl chloride vary in material quality, uniformity, thickness, and width. There are a number of other parameters that the manufacturer of high-quality windows takes into account - we will discuss them in the further description. In this review, we will look at the top manufacturers, the best PVC windows in 2019-2020.

Which PVC windows are best to choose?

First of all, it should be noted that high-quality material for PVC profiles has a smooth structure without roughness or graininess, has a uniform color, no odor or irregularities. Polyvinyl chloride is resistant to moisture, chemicals (solvents, acids, oils), and temperature changes. High-quality PVC is harmless to the environment and people. The best PVC profiles are resistant to the adverse effects of high and low temperatures, and are not subject to deformation or discoloration.

A high-quality profile does not change shape due to metal reinforcement. Such products provide reliable thermal insulation and have good sound insulation properties. In addition to heat conservation and sound insulation, plastic windows can perform other functions: protection from heat and bright sunlight, protection from burglary. In the first case, glass tinting is used during the manufacturing process; in the second option, tempering and reinforcement are used.

Due to the presence of many companies on the market, buyers often do not know which PVC windows are better. Experts recommend choosing designs not only by brand or cost, but also by personal preferences. It’s also not worth relying on the quality of products with a low price and from an unknown company.

Criterias of choice

When choosing plastic windows, you should pay attention to particularly significant indicators: the number of double-glazed windows and air chambers in the profile, the thickness and width of the profile, the quality of fittings and seals. On the question - which PVC window profiles are better. The normal profile width to ensure thermal insulation and silence is at least 50 millimeters. The best examples have a width of 58 to 70 millimeters. In northern and very noisy areas, wider

The thickness of the profile for residential premises must be at least 2.5 millimeters (internal walls) and 2.8 millimeters (external walls). Thinner walls have lower thermal insulation and noise insulation properties. The optimal number of air chambers in the profile is from three to eight units. The more cameras, the better.

Experts do not recommend choosing ordinary glass. Nowadays, double-glazed windows are produced with fire-resistant, laminated glass (virtually unbreakable). Samples are produced with a special coating to reflect sunlight. Reputable companies do not skimp on the quality of fittings. Good locking and locking devices are an equally important part of plastic windows. Silicone and rubber are used as good sealants. These materials do not deform and are durable. Rubber seals less durable and much cheaper.

The best manufacturers

There are many large companies and small firms. It is difficult for a buyer to choose a specific brand. The quality and cost of products vary greatly. The world's main manufacturers of quality windows:

• Veka;
• Kommerling;
• Deceuninck;
• Rehau;
• Montblanc;
• Salamander;
• LG Chem;
• Schuko;
• Kaleva;

There are a lot of small, little-known companies. The quality of products is difficult to verify. Therefore, when choosing, it is better to focus on reputable brands.

Human nature is indestructible: some are looking for a “freebie”, others are trying to slip a beautiful candy wrapper with “slag” inside under the guise of candy. Our portal has already described ways to deceive consumers when ordering suspended ceilings. It turned out that this is also possible when installing plastic windows. An unenlightened customer may think that this is impossible - all windows consist of glass and profiles. At the same time, plastic profiles from all manufacturers are made of the same material - polyvinyl chloride (PVC), and they look assembled windows almost the same.

The difference begins to appear after a few years (sometimes within a year), when the frame and sashes become deformed - they are difficult to open and close, there is wind from the street, condensation appears between the glass panes, and then black mold.

Therefore, it is very important to know the criteria to avoid fakes when choosing a profile for plastic windows.

Types of profiles and their classification

The main structural element of the doors and frame is the profile. It determines not only the aesthetic perception of the window, but also its strength characteristics and service life. European standard EN 12608 SR and GOST 30673-99 profiles made of polyvinyl chloride are classified according to several parameters.

1. Thickness of outer walls. The profile is a closed hollow structure with a system of partitions inside. All the basic consumer properties of the window depend on the thickness of the walls that form the structure: cost, strength and durability.

The European standard distinguishes the internal and external walls of a plastic profile. The internal walls include all the outer walls of the profile in an already installed window that are invisible to the eye. From the first definition it logically follows that the outer (outer) walls are the front walls of the window and are visible both from inside the room and from the street (see photo).

Depending on the thickness of the polyvinyl chloride in the external and internal walls, there are three classes of profiles (in this regard, the Russian standard is more stringent):

• "A"— the thickness of the external walls is >= 2.8 mm, the internal ones >= 2.5 mm according to the European standard (minimum 3.0 mm at the outer wall according to GOST), which ensures high level window strength, best heat and sound insulation;
• "IN"— the outer walls have a thickness of 2.5 mm, the inner walls have a thickness of 2.0 mm (coincides with GOST). A profile of this class retains heat 10-15% worse, is 12-17% less resistant to various types of deformation, and blocks street noise 10-20% worse;
• "WITH"— the European standard and GOST do not impose certain requirements for this class of profile. It is mainly used to make windows for non-industrial facilities. A number of companies, meeting the requirements of one of the parameters of class B, which is important, make economy class windows for the population (in general, this is a class C profile).

Unscrupulous window installers, focusing on low price, they persuade customers to install an “object” profile (class C, not a single parameter corresponds to classes A and B), intended for non-residential premises (in fact, the price is almost twice as high as the real one, but significantly lower than the cost of profile B).

Such windows do not retain heat and quickly become deformed. It is visually difficult to distinguish such a profile from a standard one (class B or A) - measurements with a caliper are required. The inscriptions on the protective film “object” can also help determine the quality of the proposed profile.

Attention: only if both parameters meet the requirements of the standard, the profile belongs to a certain class, which must be confirmed by the corresponding certificate. Without presenting documents confirming quality, it is better to refuse the transaction.

It is easier for consumers who understand profile classes to decide which plastic to choose for their windows.

2. By temperature zones. In Europe and Asia there are countries with very hot, temperate and cold climates. Window manufacturers took the current situation into account and produced their own line of products for each zone. In Europe it is tied to the hottest month of the year, in Russia - to January.

Depending on the average temperature in January, the profiles produced may be:

• lightweight version - for countries with hot climates, where the average temperature of the coldest month remains positive (must withstand short-term temperature drops down to -5 degrees Celsius);
• standard version - for a temperate climate zone with an average temperature of -20 o C in January (maximum permissible negative temperature -45 degrees Celsius);
• frost-resistant - for the Far North, where temperatures drop to minus 55 degrees Celsius.

The last two types are mass produced in Russia. Lightweight windows are produced only by the Russian company “Krauss” (Krasnodar) - they cover the entire south of Russia.

3. According to impact resistance, the profile is divided into class I and class II. Class I PVC must withstand the fall of a special striker weighing 1.0 kg from a height of 1.0 m at a plastic temperature of minus 10 degrees Celsius. For class II, the fall height is increased to 1.5 m.

This classification makes it possible to determine how correctly the internal partitions are located (they counteract the deflection of the outer walls into the structure under mechanical stress) and how the plastic reacts to lower temperatures (everyone knows the property of plastics to become brittle in severe frosts).

Consumer properties of profiles that you need to pay attention to

Which profile to choose for PVC windows so that it is warm, quiet, airtight, inaccessible to burglary and, at the same time, not to contact scammers? The main characteristics will help with this.

System width

The first indicator you should pay attention to is the width of the profile structure. It depends on it how warm and cozy it will be in the apartment or wooden house. For consumers who are encountering plastic windows for the first time, it is difficult to understand how the width of the frame and sash affect the comfort in the room. Let's try to explain.

A double-glazed window is installed in the window sash, which consists of several glasses fixed around the perimeter with a PVC profile frame. The air pockets between the glasses are called chambers. In standard windows, there is simple air in them; in the “Premium” segment, air is pumped into the chambers inert gas to improve all the characteristics of a double-glazed window.

From school lessons physicists know that air is a poor conductor of heat, and glass with an air pocket is a poor conductor of sound. Therefore, the more cameras in a double-glazed window and, consequently, the number of glasses, the more comfortable it is to stay in the room. Window manufacturers mainly offer the classic version of the profile width - 58 mm, which allows the installation of single-chamber windows. For two cameras a minimum of 70mm is required.

For regions of the Far North with their extreme temperatures, windows with three or even four chambers are offered. But this requires an appropriate profile width: 90 mm for 3 chambers, 110-120 mm for 4. This type of product belongs to the “Premium” class. Due to their heavy weight, such windows are not recommended for installation on balconies and loggias.

Number of profile cameras

The window design has two units with cameras. One is a double-glazed window, which is discussed above. The second is the profile itself. The profile is hollow. To create structural strength, fasten fittings and increase the level of heat and sound insulation, there are partitions inside the profile. The hollow volumes created by them are called chambers. The more there are, the better the performance of the window. The location of the jumpers is calculated mathematically - each of them performs a specific function.

On sale you can find 3-chamber profiles (this is the minimum possible number of cameras) and 7-chamber profiles. The most popular ones are 5-chamber ones. They offer the best combination of price and quality.

It is difficult to check the quality of the samples offered by the company by the installer, but you can pay attention to the little things that will say a lot:

• The company logo, date and place of manufacture applied to the protective tape will with a 90% probability confirm the origin of the product;

• The surface texture will also help: for high-quality windows, the surface of the plastic should be perfectly smooth. Graininess indicates the Chinese origin of the product or Russian handicraft production;
• The applied paint should be uniform in color and without streaks.

Profile Manufacturers Rating

The manufacturers' ratings will help you figure out which profile for plastic windows is better. In this case, the rating can be compiled based on the popularity of the product, its cost, levels of heat and sound protection, strength, etc.

There is also a commercial factor involved. Some manufacturers buy sites from sites in general ratings, which is difficult to do when ranking products based on one indicator. Therefore, so that the portal’s editors are not suspected of a commercial approach to ranking windows, we will create two types of ratings: for global brands and Russian manufacturers.

Rating of the world's best manufacturers of plastic windows

Various specialized sites put KBE, Rehau, Century, Salamander, Mont Blanc in first place. It all depends on the indicators that were taken as a basis. But these manufacturers are distinguished by nuances, and it may turn out that the leading Rehau is not exactly suitable for a particular buyer. Therefore, we will consider the products of these companies without determining a specific place in the ranking - they all deserve to be in first place.

In terms of popularity on the Russian market, it is inferior to all the companies listed in the rating, since there is no plant in Russia. In terms of technical indicators, it is not inferior to any manufacturer.

Produces profiles with a width of 60-76 mm:

• Design 2D - 60 mm, number of cameras 3.5 (4);
• Design 3D - 76 mm, number of cameras 4.5 (5);
• Streamline - 76 mm, 5 cameras.

Advantages:

• excellent design;
• European quality control;
• control of sales points (dealers) throughout Europe.

The main and only disadvantage is the high cost (compared to Veka and Rehau, it is 35-40% higher).

KBE

A famous German company with factories in Russia (the cities of Voskresensk and Khabarovsk). Experts did not find any differences in the quality of windows from the products of competing companies, with the exception of some nuances.

Attention: the company has come up with an excellent marketing ploy - it issues an “Official Partner Certificate” to the best window assemblers, which does not give any guarantees to the customer regarding the quality of the windows.

The factories offer the customer a fairly impressive line of profiles, with a width from 58 to 127 mm:

• “Engine” and “Etalon” - 58 mm, 3 cameras;
• "KVE-Expert" - 70 mm, 5 cameras;
• “KVE-88” - 88 mm, 6 cameras;
• “KVE-Expert+” - 127 mm with 5 cameras in the frame and sash and 4 in the impost.

Among the advantages it should be noted:

• democratic price - products are available to mass consumers;
• high quality;
• launch of the greenline technological line.

No disadvantages were identified either in consumer reviews or in the expert community.

MONT BLANC

Austrian manufacturer of budget, high-quality products. After the construction of a plant in the Moscow region (Elektrostal), it became well known to the Russian consumer.

Produces a line of 7 types of profiles with a width from 58 to 120 mm:

• “Logic” - 58 mm, 3-chamber;
• "Tempo 60" - 60 mm, 5-chamber;
• “Nord 70” - 70 mm, 5-chamber;
• "City 120" - 120 mm, 5-chamber.

Among the advantages:

• budget price;
• long period of operation without loss of consumer properties;
• wide range of produced profiles.

Among the disadvantages, one can note the shortcomings of the marketing service - for 15 years the company has not made any attempts to obtain an ISO certificate for the products of the Russian plant.

VEKA

The German company with half a century of experience is one of the sales leaders. Built the VEKA Rus plant in the Moscow region. It produces white and colored profiles with a width from 58 to 90 mm, which do not turn yellow when exposed to UV rays.

The profile line consists of a number of models with a width of 58-90 mm:

• “Euroline” - 58 mm, 3-chamber;
• “Proline” - 70 mm, 4-chamber;
• “Swigline” - 82 mm, 5-chamber;
• "Alphline" - 90 mm, 6-chamber;
• "Softline 82" - 82 mm with 7 cameras.

Product advantages:

• Consistently high quality;
• big the lineup.

A significant disadvantage of the product is that the consumer significantly overpays for the brand - Russian-made products are practically no different in price from the profile produced in Germany.

REHAU

Another German company with extensive experience in the production of plastic windows. The company was created to produce products for the middle class. Currently, this line has been erased - at a price you can find products for every taste. It adheres to an interesting tactic: it maintains the price level of its main competitor, the Veka company, on the market.

In 2002, the company launched its own plant in Gzhel (Russia). Profiles are available in widths of 60 mm, 70 mm, 80 mm and 86 mm:

• “Blitz” (economy class products) - 60 mm, 3 cameras;
• “Brillant-Design” - 70 and 80 mm, 5 and 6 cameras;
• "Geneo" - 86 mm, 6 cameras.

The manufacturer’s pros and cons completely replicate the advantages and disadvantages of its competitor, Veka (see above).

Rating of the best Russian manufacturers of plastic windows

Enterprises with purely Russian origin have a short history, but have managed to compete with Western manufacturers - the sales volume of Russian windows is increasing every year. Among the best:

Kaleva

A Russian company with a Finnish name, the only one in the country that operates on a full cycle: from profile production to installation of windows for the customer. This is both a plus and a minus for the company at the same time.

• Plus: by producing and installing a very high quality profile yourself, the manufacturer significantly reduces the price of the finished window.
• Disadvantage: in the regions, the majority are not ready to work at the level of the parent enterprise installed windows do not meet the warranty period and have to be reinstalled again. The company is not yet eager to somehow influence the work of its regional centers, leaving customers alone with dealers.

PANORAMA

The company from St. Petersburg has 20 years of experience. According to experts and consumers, the product quality is one of the best - it can easily compete with German brands. The profiles have an ideal balance of rigidity, good noise and heat insulation, and a pleasant design.

However, the legacy of the Soviet past is taking its toll - the company’s management works poorly with consumers and pays little attention to advertising. In terms of potential, the company is capable of becoming the leader of PVC windows in Russia.

PROPLEX

Proplex is a young Russian company that is rapidly winning the market from the old-timers. Windows developed specifically for Russian conditions (the model range consists of profiles with a width of 58-127 mm) have affordable prices and high consumer characteristics.

Further expansion in the Russian market and entry to the international level is hampered by two unpleasant moments:

• backward profile design;
• lack of an international ISO quality certificate.

Selecting the StroyGuru portal

When choosing a leader among global brands, the portal's editors unanimously voted for Rehau. Our choice is explained simply: thanks to this company, window production is on the verge of revolutionary changes - the innovative material “Rau-fipro” has been patented.

The portal’s employees would personally install windows from only two companies: “Mont Blanc” and “Panorama” - why pay for a brand if the quality of the named companies is no worse. The votes were evenly divided.

Conclusion

The polyvinyl chloride profiles presented on the Russian construction market are able to satisfy consumer requests in all basic parameters: cost, strength, durability, design, level of heat and sound protection. The only thing is to be careful and not fall into the hands of scammers.
