Plastic windows rehau and century comparison. Windows "Rehau": customer reviews, technical characteristics. Which windows are better than "Century", "Newton" or "Rehau"? Reviews. Profile outer wall thickness

If a person asks the question: "Which windows to choose: Veka (Veka), KBE (KBE) or Rehau (Rehau)?" in the rating of the most famous and demanded companies both in the Russian and international markets.

It is impossible to decide unequivocally that this or that manufacturing company is better, because the plastic window is different complex design, where constituent parts are: reinforcement, PVC profile, seals. The main operational properties of the profile are: heat protection, sound insulation and waterproofing. Some of these indicators are better for REHAU, others for KBE, and others for Veka.

If you want to get the most informative answer to your question, you need to clearly define what functionality you primarily need from new windows: maintaining an optimal microclimate at any time of the year, protection from extraneous noise from the outside, a good level of waterproofing, etc.

Technical characteristics of windows

1.1 Number of cameras in a profile

The air cavity that forms between the partitions of the profile is called a chamber. With an increase in their number, the temperature in the room also increases. The smallest number of cameras in a profile is three. In this case, the coefficient of resistance to thermal protection is on average 0.62. If the profile is four-chambered, the coefficient reaches 0.64, five-chambered - 0.68, six-chambered - 0.72. As for noise isolation - the three-chamber profile absorbs 15-20 dB of noise, this figure increases by another 8-10 dB with each additional chamber. Veka manufactures a profile with 3-6 chambers, KBE - 3-6.6, REHAU - 3-5.5.

Obviously, the number of cameras in the profile will not help us identify the leader - all three companies offer almost the same parameters.

1.2 Width of the outer walls of the profile

The functionality of the window, its reliability and service life depend on the width of the walls (external). After all, the thickness of the walls determines not only the level of thermal protection, sound insulation of the window, it ensures its resistance to physical and mechanical stress, deformation. The thickness of the outer walls of the profile, regulated by GOST 30674-99, must be at least 3 mm.

The manufacturing company Veka adheres to world standards and offers its customers a profile with a wall thickness of 3 mm. It is VEKA products that have become the basis of Russian standards.

The KBE company manufactures a profile with an outer wall thickness of 2.8 mm, which belongs to category "A" of the Russian standard (2.5 - 3 mm).

As for REHAU, in order to reduce the cost of production, the company offers its customers a profile with an outer wall thickness of 2.5 to 3 mm.

1.3 Maximum width of a glass unit

It is wrong to focus only on the profile, because the indicators of heat and sound insulation also depend on the thickness of the glass unit. Only a strong profile with a special sash design can withstand a glass unit of good thickness.

The most stable profile of the Veka product line is VEKA-alphaline, it is able to withstand a glass unit up to 50 mm thick.

Among KBE profiles, KBE Expert turned out to be the most stable - it can withstand a double-glazed unit up to 58 mm thick.

Rehau profiles have a permissible glass unit thickness of only 44 mm - this figure is typical of the REHAU Sib-Design model.

If we compare the readings of the KST (coefficient of resistance to heat transfer) of the three companies, then the picture changes somewhat - VEKA is ahead of the curve: Rehau - 0.79, KBE - 1.05, Veka - 1.37 m² ° C / W.

Physical characteristics of windows

2.1 Thermal protection of a window

The level of heat-shielding properties of a profile is measured by KST (coefficient of resistance to heat transfer). This indicator is formed from the ratio of the temperature at the edge of the profile to the density of the air inside. The higher the coefficient, the better the heat is retained in the room, the less cold air enters inside.

2.2 Waterproofing windows

In homes, moisture is always an unwanted "surprise". This is especially true for those areas where its concentration is high and without additional penetration from the outside, for example, kitchens, bathrooms. The waterproofing characteristics of a profile entirely depend on the shape and quality of the seal (elastic gasket between the frame and the sash). Due to it, the most tight fit is achieved, thereby protecting the room from moisture and cold air. Frost and condensation on the windows are signs of a bad seal.

To date, the most versatile material for the production of the sealant was EPDM (ethylene propylene rubber). It does not lose its properties when low temperatures, does not deform when compressing, bending and stretching.

All three companies use this type of seal, but the KBE company uses another type - TPE, which is manufactured simultaneously with the profile, and has high levels of tightness and thermal insulation.

The shape of the seal will help us to recreate the most accurate picture.

Veka seals are mostly single-leaf. A petal is a seal element that is slightly separated from the product. Such seals are shaped like a tube. A similar form of seal is used in KBE systems.

The standard REHAU gasket has two petals and there is no additional air space.

Practice has shown that the shape of the seal in Rehau window systems is the most practical. Due to the fact that the petals do not concentrate moisture, there is no problem of condensation. The service life of such a seal is increased by 3-4 years.

Obviously, REHAU windows are the most functional in terms of waterproofing.

2.3 Strength characteristics of the profile

Plastic serves as the main material in the process of manufacturing windows. However, he is not able to withstand the pressure from the glass unit and negative factors on his own. the environment... Therefore, a PVC profile with a length of over 500 mm, according to GOST, is subject to mandatory reinforcement. The reinforcing insert is a galvanized strip metal profile (thickness 1.5-2 mm). The quality of this part is largely influenced by its shape, it can be U-shaped and closed square. Qualitative characteristics this part depends on its shape.

During the reinforcement of the Veka profile, a square profile is used to a greater extent. For KBE and REHAU windows it is possible different options, more often it is a G-shaped or square profile. The first is more durable than square, but square wins significantly in terms of stability and rigidity.

2.5 External characteristics, the complexity of care during operation

Window REHAU systems, KBE and Veka are distinguished by a wide range, where products are presented that are different in functionality and external characteristics. Buyers are given the opportunity to choose the most suitable way the location of the sash, the type of opening, additional options: climate control, mosquito net, toning, laminating, etc. This allows you to order a window not only of a suitable shape, but also suitable color, shade and texture.

In terms of aesthetic characteristics, KBE, VEKA and REHAU windows are not inferior to each other.

Plastic windows require minimal attention and care during operation. They can be washed and wiped periodically special means Is all that is required from the owner of the windows. REHAU made the task even easier - the most smooth profile, which practically has no roughness, does not get dirty for a very long time, which eliminates the need for frequent washing.

2.6 Service life of windows

Durability of PVC profile windows is their main advantage. How can a client know the average service life of a company's products? The manufacturers did it for you with the help of special experiments - this experiment speeds up time and reproduces all possible loads on windows. Temperature, pressure, humidity are often changed in the chamber. As a result of such a study, the service life of the window is revealed. For standard Veka profile and KBE have defined a period of 40 years, the REHAU profile is much longer - 60.

2.7 Comparative characteristics of the profiles REHAU, Veka and KBE

It was not possible to identify a specific winner among the three leading manufacturers of window systems - each product is of high quality, good performance characteristics and excellent appearance. However, in terms of the level of sound insulation and thermal protection, the VEKA company has become the leader, in addition, the products of this manufacturer are the most durable and rigid due to closed reinforcement. But a better and more reliable seal has Rehau products, which prolongs the life of its windows. Worthy competition to them are profile systems KBE.

In a nutshell, profile differences based on customer reviews would look like this:

• “The VEKA profile is of high quality and durable, its walls are thicker and it is generally made soundly, has a noble white matte surface and is pleasant to the touch”;
• “REHAU is a very popular brand, but it is becoming more and more difficult to purchase windows from the original REHAU profile, because it is often counterfeited, has cheap Russian, Turkish, Chinese counterparts quite Low quality»;
• “KBE is a well-known brand on the market, but in terms of quality it is still inferior to VEKA and REHAU, although the differences between them are insignificant. There are also elite series of this brand, which are very good. "

But in order to get a complete and reliable picture, it is better to consider positive sides all three profile brands.

Plastic windows VEKA

One of the most popular types of profiles that are widespread in glazing country houses, balconies and apartments. Most of the VEKA window series have a low cost, which does not compromise quality. It is also necessary to note the following parameters:

• Only safe high quality materials are used in production;
• The profiles are elegantly shaped;
• The only A-class profile in Russia;

Only VEKA profiles are galvanized metal reinforcement closed section, which affects the mechanical stability of products. Vek's profile has rightfully earned the status of a high-quality profile in Russia, thanks to its unchanging principles in the field of quality control and building work with window manufacturers.

Plastic windows REHAU

The advantages of REHAU windows are best seen on the example of the most popular series - Rehau Basic-Design. This model has the following parameters:

• The width of the three-chamber profile is 60 mm;
• Standard indicators for noise and heat insulation;
• Windows do not require special care, they are very technological and reliable
• The main advantage is the relatively low prices for windows from this profile.

They are used for glazing of cottages, balconies and apartments, just like VEKA. but modern requirements for energy saving, they provide for the use of profile systems with a width of 70 mm in construction. Therefore, in the near future, in companies responsible to consumers, base case will become the Rehau Sib-Design profile.

Plastic windows KBE

KBE - are considered a classic brand of plastic windows. They have become widespread due to the following criteria:

• The production uses the "greenline" technology, which completely excludes the use of heavy metals;
• KBE windows can withstand temperatures up to -60 degrees;
• They have various design solutions.

Due to their properties, KBE windows are often used in the mass development of capital objects: residential new buildings, office centers, state buildings. institutions.

If you asked the question "Which windows are better than veka (century) or rehau (rehau)?", Then you have probably already studied enough and know that these manufacturers PVC profiles occupy a leading position.

It is unambiguous to say that one firm cannot be better than another. consisting of several different parts: PVC, reinforcement and seal. It has a lot of properties, such as sound insulation, heat protection, waterproofing. Some characteristics are better for REHAU, others for Veka. In order to understand this issue in detail, you need to understand what you expect from new windows in the first place: minimal heat loss, quietness in the room, high waterproofing rate, or something else.

Specifications

Number of cameras in a profile

The chamber is a hollow air space between the partitions inside the profile. The more such cameras there are, the warmer it is in the room. The minimum number of cameras in a profile is 3. The coefficient of resistance to heat protection in such a profile is 0.62 on average. For a four-chamber profile, the coefficient on average is 0.64, the same indicator for a five-chamber profile is 0.68, and a six-chamber profile is 0.72. The three-chamber profile attenuates an average of 15-20 dB of noise, and each additional chamber - another 8-10 dB.

Veka manufactures profiles with 3-6 chambers, REHAU - from 3 to 5.5. Why 5.5? The fact is that the reinforcement (an iron insert located in the middle of the profile) of some models of the REHAU profile is slightly mixed to the side and does not completely occupy the entire central chamber, which is why another partition is formed inside. According to modern Russian standards, such a partition and the airspace separated by it can be considered a camera. But the Rehau company itself does not position windows of such a configuration as six-chambered, but modestly names the number of cameras as 5.5 or 5 (6).

We will not be able to decide which windows are better than Veka (century) or REHAU (rehau) by the number of cameras in the profile. Both firms can offer a similar choice.

Profile outer wall width

The width depends not only on the thermal protection and sound insulation of the window, but also on its resistance to deformation.

According to GOST 30674-99 "Window blocks made of PVC profiles", the recommended thickness of the outer wall of the profile is at least 3 mm.

In the Veka product line, you will not find a profile with a lower index. Veka does not save on the thickness of the profile walls and is attentive to all world standards (by the way, Veka windows have become the basis of Russian standards).

But REHAU, in order to save money, can offer its customers a profile with thin walls from 2.5 mm and more.

Maximum width of a glass unit

It is wrong to say that the thermal protection and sound insulation of a window depends only on the profile. In many ways, these indicators are influenced by the glass unit, or rather its thickness. In order to install a double-glazed unit of maximum thickness, the profile must have special strength and a special sash design.

The most stable profile among Veka products - VEKA-alphaline can withstand the weight of a glass unit up to 50 mm thick. The maximum permissible width of a double-glazed unit of REHAU profiles is only 44 mm. This indicator is possessed by the REHAU Sib-Design model.

From the foregoing, it can be understood that Veka produces windows with a greater degree of sound insulation and heat saving. If you look at the maximum readings of the coefficient of resistance to heat transfer of these two companies, you can see another confirmation of our words.

The maximum CST of the Rehau profiles is 0.79, the Veka - 1.37.

Physical properties

Heat protection and noise insulation of a window

These two indicators depend on the same characteristics of the profile, so we will not separately consider noise insulation and thermal protection, but we will do it together.

The heat-shielding properties of a profile are measured by the coefficient of resistance to heat transfer (KST). This indicator is revealed by the ratio of the temperature at the edges of the profile to the density of the air inside it. The higher the coefficient, the less heat leaves the room and the less cold streams penetrate inside.

Noise is measured in decibels (dB). When comparing firms, we will take into account the noise level in the room with these windows, as well as how much the profile dampens sounds from the street.

Now we will take a closer look at each indicator and decide which better windows veka or rehau in terms of sound insulation and frost resistance.

Waterproofing a window

In residential areas (especially with high level humidity, such as kitchen and bathroom), it is very important how protected the window from moisture penetration from the street. Profile waterproofing depends on the quality and shape of the seal.

The seal is an elastic gasket between the sash and the frame. It serves for more snug fit, protecting the room from moisture and cold. Due to a poor-quality sealant, condensation and frost may appear on the window.

On this moment The most practical and versatile seal material is EPDM. It is the most frost-resistant, not subject to deformation during compression, stretching and bending. Both companies use this particular material, so that the seals of both companies are of excellent quality.

Decide which plastic windows better veka or rehau we can in the form of a seal.

Century seals are mostly single-lobed. The petal is the part of the seal that is slightly separated from the entire product. In addition, the seal of this company is a bit like a tube in shape.

The standard REHAU gasket has two petals and there is no additional air space in it. He's better than Century

Experiments show that the shape of the Rehau seal is more practical. Condensation does not accumulate in the petals (unlike a closed chamber, into which moisture can get), the seal does not freeze and does not wear out for 2-3 years longer.

In the question of which plastic windows are better waterproofed by veka or rehau, REHAU undoubtedly wins.

Profile strength

Plastic is not able to independently withstand the load from the severity of the glass unit and the influence external environment... Therefore, according to GOST 30674-99, all PVC profiles with a length of more than 500 mm are subject to mandatory reinforcement.

A metal profile made of galvanized strip 1.5-2 mm thick acts as a reinforcing insert. The quality of this part is largely influenced by its shape, it can be U-shaped and closed square.

For the reinforcement of the Veka profile, a square profile is mainly used. REHAU windows are available in square or G-shape. G-profile stronger than a U-shaped one, but it cannot be compared with a square one in terms of rigidity and stability.

Appearance and ease of maintenance

and Veka are distinguished by their enormous functionality: the choice of buyers is given a large selection of ways to arrange the sash, types of window opening, as well as a bunch of additional opportunities such as mosquito nets, climate control systems and more. In addition, the profile of both companies can be given any shape, shade and texture. In terms of external characteristics, the REHAU and Veka windows are on the same level.

Maintenance of plastic windows is minimal. All that is required of you is to wash them periodically. REHAU decided to make life even easier for its customers. Their profile has a perfectly smooth surface, PVC particles are located so close that irregularities or roughness of the profile can only be seen under a microscope. Thanks to this technology, the profile gets dirty less often and it is much easier to wash it.

Durability of windows

Hardly anyone wants to change their windows every 5-10 years, so their durability is of the utmost importance. In order to identify the maximum service life of the profile, special experiments are carried out. The window will be placed in the “accelerated time” chamber, where the load is recreated several decades in advance. In the chamber, the pressure, temperature and humidity level are periodically changed. The observation reveals the average lifetime of the window under normal conditions.

As a result of such experiments, it was revealed that the standard Veka profile will serve faithfully for 40 years, and the REHAU profile - 60.

Comparison of REHAU and KBE profiles

It was not possible to identify the winner in terms of the main characteristics of the profile - the undoubted leader in terms of thermal protection and sound insulation, in addition, the products of this company are more durable and tough. However, REHAU has a better seal. The windows of this company are easy to use and last much longer.

Now let's compare the individual profile models of both companies.

Main parameters of profiles

The optimal degree of thermal protection will be provided to you by models with a high coefficient of resistance to heat transfer. REHAU Delight-Design, REHAU Brillant-Design, VEKA-swingline, VEKA-softline are best suited, but VEKA-alphaline and VEKA topline + will be the best solution.

For windows where special meaning has sound insulation, you need to select a profile with the maximum possible width of the glass unit: REHAU Sib-Design, VEKA-alphaline and VEKA topline +.

In all other cases, you can choose a profile according to your financial capabilities and personal preferences.

In our country, equally popular metal-plastic profile systems from REHAU and Veka. The quality and characteristics of the products of both concerns are almost the same, the assortment is wide. Unsurprisingly, it can be difficult for shoppers to understand how different brands differ. And often they have to choose a solution at random. Comparison of profile systems by several key parameters will help to determine preferences: class, chamber, number of seals, type of reinforcement, installation depth, limiting thickness glass bag.

Class

The class of PVC profile depends on its thickness without metal reinforcement. The "A" class includes profile systems with an outer wall of 3 mm or more. Products with thinner outer walls up to 3 mm thick belong to class "B".

Both REHAU and Veka release plastic systems with 3 mm A-class walls.

Number of air chambers

Three- and five-chamber profiles

As a rule, budget systems have 3-4 chambers (cavities), which are enough to prevent the formation of condensation and reduce heat loss at facilities in central Russia. Veka has only Euroline profile with 3 chambers, REHAU has two three-chamber solutions - Basic and Euro Design. Also "REHAU" produces one four-chamber Thermo Design system. You can choose profiles from two manufacturers with 4 cameras and in the middle price niche. These are Veka Proline and REHAU Delight.

5- and 6-chamber products with a higher coefficient of resistance to heat transfer retain heat most effectively. For the six-chamber system Alphaline from "VEKA" the parameter is 0.94, for Brillant Design from "REHAU" it is slightly lower - 0.79.

In terms of thermal protection, the systems of both manufacturers are equivalent.

Number of sealing contours

Two and three contour seals from REHAU

A standard swing-out window is equipped with two cold-blocking seals. A three-circuit seal is more reliable, since it is considered reinforced. It is equipped with the Geneo system from REHAU. The three lip seals are more effective at closing gaps and isolating heat. The quality of the sealing rubber is much higher in REHAU.

REHAU offers the most insulated series with three sealing circuits.

Reinforcement type

Reinforcement varieties

So that the plastic does not bend and break under the weight of the structure, it must be strengthened metal profile- to reinforce. There are 3 types of reinforcement with different shapes. These are L-, U-shaped and closed reinforcement.

REHAU reinforces the plastic with U-shaped metal inserts, Veka reinforces the profile with hollow square tubes in almost all series, because the volumetric PVC systems from this manufacturer are stronger. However, it should be borne in mind that such a closed reinforcement affects the cost of products - VEKA windows and doors are more expensive.

Veka windows, reinforced around the entire perimeter, are stronger, but they also have a higher cost.

Installation depth

REHAU profile with an installation depth of 70 mm

The installation width is the depth of the window block. For budget systems like Veka Euroline or REHAU Basic, it is 60 mm. Most profiles are medium price segment both manufacturers have an installation depth of 70 mm. Thicker and warmer Veka Topline + profiles with 104 mm mounting width. They are designed for the same glass bags with maximum thickness as the GENEO counterpart from REHAU.

In terms of installation depth, the products of the concerns do not differ.

Maximum thickness of a glass unit

Thicker glass bags provide better thermal and acoustic insulation. Rehau Basic, Euro and Thermo systems suitable for thin 35 mm glass fillings are not the best solution for houses on busy streets. With them, street noise makes itself felt.

For reliable sound protection, it is better to choose the GENEO or DELIGHT profiles of the same manufacturer, designed for a thicker filling (53 and 40 mm, respectively). The plastic of these series in combination with a thick glass bag effectively blocks sounds from the street. This combination prevents the formation of condensation due to the installation of a two-chamber package with different chamber volumes.

The width of the glass filling of 50 mm in Alphaline PVC from "VEKA", sufficient for the installation of a three-chamber double-glazed unit, significantly affects the cost of glazing.

REHAU and VEKA produce profiles suitable for thick glass bags with 2-3 chambers. The advantage in the thickness of the filling is with REHAU, whose Delight system is designed for a double-glazed unit with a record thickness of 53 mm!

Aesthetics and convenience

Both manufacturers wide range of products. Find something suitable for functions and appearance not difficult. Windows can differ in shape, size, profile color or surface texture. Products of both concerns are decorated with lamination and toning, open in different directions, equipped with mosquito nets, and provide climate control. You don't need to take special care of the plastic. It is enough to wipe the windows from time to time from dust, wash.

In terms of aesthetics, the VEKA and REHAU systems are not inferior to each other. Many REHAU profiles surpass VEKA counterparts in terms of smoothness - they are easier to care for and need to be cleaned less often.

What to choose?

Each concern improves technology and offers quality products, attractive in appearance and easy to operate. To choose a suitable solution in any case for the buyer. It is not easy to decide, so we turned to an expert. To the question "Which is better - the" REHAU "or" VEKA "systems?" the specialist of the company "Window Systems" answers:

“Veka reinforces plastic with metal in a closed loop and offers stronger profiles. But the U-shaped reinforcement of REHAU also provides sufficient strength. The advantages of REHAU plastic windows are a more durable seal and longer service life. Therefore, if tightness and durability are a priority, it is better to choose the REHAU system. Such windows will last up to 60 years. "

Alexey Mironov, master window maker with experience window mounting more than 20 years

Both companies have long proven their competence as manufacturers. Both have developed and produced a wide range of profiles with different technical parameters... All structures are made of durable PVC, with good seals and reinforcement, on the specific properties of which the characteristics, quality, beauty, and service life of the finished product depend.

It is more correct to assess "good and bad" for each individual parameter, and having decided what is more important in your case, buy windows from a particular manufacturer. To be as objective as possible, let's try to compare the designs of two well-known companies in terms of the main technical indicators, but ...

Whichever profile you choose - the amount of heat and silence saved in the house will depend on professional installation. Handicraft work will ruin the highest quality product, no matter how many chambers there are in the profile and the glass unit.

Number of cameras

The PVC frame consists of many cavities, separated from each other by partitions. These are air chambers: the more of them, the less chances for the cold to penetrate into the room, which means that the heat in the house also depends on their number. Each window of any company has at least 3 cameras. Compare:

• Veka company produces window constructions with 3-6 cameras;
• in the Rehau windows there are 3-5.5 of them (the half indicator is associated with the features of the profile design. According to Russian standards, this is equivalent to 6 cameras).

Conclusion: by the number of cameras, the windows of both manufacturers are in the same position. Both will offer similar solutions if the intimacy of the profile is a fundamentally important choice parameter.

Outer wall size

Width affects:

• on the ability of windows to retain more heat;
• for noise insulation;
• on the rigidity of the structure, its resistance to mechanical damage, deformation under the influence of a heavy glass unit.

The norms in force on the territory of Russia in relation to the width of the profile are specified in GOST 30674-99. The document states that the outer wall cannot be less than 3 mm. Century maintains this standard. In the model line of the company, all window profiles have a large width. This means that the manufacturer does not save on materials and seriously evaluates the practice of world standardization.

In the list of Rehau window profiles there is an economy class product with a wall width of 2.5 mm. Minus half a millimeter may not critically affect the atmosphere in the room, but the very fact of non-compliance with the accepted standards is alarming.

Glass unit width

Warmth and silence to a greater extent depend on the installed glass unit, more precisely on its thickness. To keep heavy weight over several decades, a frame of appropriate size and strength is required.

Conclusion: if the window requires maximum protection from the cold, choose suitable design among the profiles of the Century. This is also indicated by the heat saving coefficient: 0.79 for Rehau versus 1.37 for a competitor.

Other important characteristics to compare

Pay attention to:

• waterproofing: depends on the seal, on its quality and shape. According to this parameter, Rehau windows with two-leaf gaskets win, which are more practical, do not contribute to the accumulation of condensate, do not freeze and serve for 2-3 years more;
• strength: to increase permissible load, the profile is reinforced with a galvanized metal frame. The toughest are closed square shape... Veka releases such windows. The competitor produces profiles on a L or U-shaped frame. They are less stable;
• service life: it has been experimentally proven that Rehau windows will last about 60 years, and Veka will have to be replaced 20 years earlier.

The models with the highest heat transfer coefficient will provide an optimal atmosphere in the house. In this category are windows from Rehau - Delight-Design, Brillant-Design and Century - Swingline and Softline.

If the apartment overlooks the roadway or there is an airfield nearby, a plant emitting a constant hum, give preference to structures with the widest glass unit. Vek has such - alphaline and topline +, and Rehau - Sib-Design.

When preference is given to design, color, toning, fittings shape and other parameters, you should be guided by your own taste, general interior concept and price. By the way, according to this criterion, the models of different companies do not have significant discrepancies.

REHAU or Veka - which one window profile better? There is no single opinion. Focus on the indicators that are more important. If the second is leading in terms of sound insulation, heat conservation, profile strength, then the first is ahead in terms of sealing quality and durability.

Anyone who wants to understand which profile is better - Veka or Rehau, probably already knows that both of these companies are recognized leaders in the production and sale of PVC profiles. But which brand is still better? To answer, let's compare plastic eyelid and rehau windows according to several main criteria.

Compare profiles

One of the main indicators is the number of chambers, air cavities in the profile. The more of them, the warmer and quieter the room. A profile with three cameras reduces the level of street noise by 15-20 decibels, each subsequent camera (fourth, fifth) will reduce the noise by another 8-10 dB.

So, Veka profiles have 3-6 cameras, Rehau - 3-5.5. How is this possible - "half a camera"? It's all about the "modesty" of the manufacturer - according to Russian standards, its windows are considered six-chambered, and the company itself, due to the design features, positions them as 5.5 or 5 (6) -chamber.

Conclusion: choosing the eyelid profile or rehau, we will not be able to find out which is better, since the number of cameras is the same.

Compare waterproofing

The waterproofing of the profile is largely dependent on the seal. It consists of an elastic rubber gasket located between the sash and the frame. Thanks to him, the room is protected from cold and dampness, and due to poor-quality material, frost and condensation can form.

Both companies make seals from frost-resistant EPDM - ethylene-propylene rubber that resists any deformation. Since the material is the same, let us compare the seals in shape: in the Century they are single-lobed and tubular. And at Rehau, the seal has 2 petals, there is no air space in it. Due to its more practical form, condensation and freezing are not allowed in the petals, and its overall service life will be 2-3 years longer than that of a competitor.

Conclusion: according to the criterion of waterproofing plastic windows veka definitely lose to models rehau.

Compare appearance

Both the one and the other company have carefully worked on the functionality of the windows. The buyer can choose any shape, texture and shade. In the construction of windows there is different ways sash and window opening positions, they can be equipped with additional options... Therefore, externally, the windows of Rehau and Veka look dignified.

As for care - plastic windows are easy enough to clean. But even this process has been simplified by Rehau even more: their profiles have absolutely smooth surface due to the closest arrangement of polyvinyl chloride particles. Therefore, roughness or irregularities can only be seen under a microscope. As a result, the profile is less dirty and will need to be washed even less frequently.

Plastic windows Veka vs Rehau: which ones will last longer?

Perhaps, the issue of durability is the most important one. To find out the answer, real scientific experiments were carried out: the windows were placed in chambers of "accelerated time". They create conditions that are equal to the load for tens of years. As a result, it was concluded that the average service life of a standard Veka profile is 40 years. Rehau double-glazed windows will withstand all 60!

Choose quality, reliability and durability!
