Which windows are better: VEKA or REHAU. Which is better: Veka or Rehau windows? How to choose plastic windows for the house? Which window profile is better than century or rehau

Today, the market for window products is simply filled with offers from various manufacturers. However, everyone is hearing plastic windows Veka, KBE, Rehau. For a long time they occupy leading positions in the ranking of Russian and European companies which undoubtedly testifies to their demand. For example, the company Windows of Comfort has been producing plastic windows in Kaluga based on the Veka profile for almost 15 years. What then are the advantages and disadvantages of this profile compared to other competitors?

In loggia glazing, especially when it comes to the warm method, various PVC profiles from the above world brands are also used. We will briefly talk about the main qualitative characteristics of Veka, KBE, Rehau profiles in this article.

Firstly, it is impossible to give an unambiguous answer to the question which of these profiles is better - Veka, KBE or Rehau. Each of them has its own advantages, which are manifested, for example, by comparing the parameters of the properties of heat, sound, waterproofing. So, first things first.

Technical parameters of Veka, KBE, Rehau windows: similarities and differences

Profile

The number of air chambers - cavities in the profile directly affects the preservation of heat in the room and sound insulation. The more of them, the higher the level of protection. Let's compare the number of air chambers, which, although they differ, but slightly, in our companies:

• Veka - 3–7;
• KBE, 3–6;
• Rehau - 3-5.

Another important indicator for the profile is the thickness of its walls. The thicker the profile, the more reliable, stronger, more durable it is, the higher its performance characteristics. GOST 30674-99, this parameter is regulated at 3 mm or more. It is also followed by other global manufacturers. If the wall thickness is from 2.5 mm to 3 mm, it is classified as category A. For our companies, the indicator is kept at the level of:

• Veka - from 3 mm;
• KBE - 2.8 mm;
• Rehau - 2.5–3 mm.

One simple conclusion follows from this: the Veka profile is able to withstand more intense mechanical loads than its competitors.

Additionally, in order for the plastic profile to withstand significant loads, it is subjected to reinforcement. In accordance with the standard, this is a mandatory procedure for products exceeding 50 cm in length. It is the use of metal galvanized L-shaped or square frames 1.5-2 mm thick in the profile. Veka profiles are more common with square, closed-section reinforced inserts, which give significant stability and rigidity to the frame, KBE and Rehau are characterized by L-shaped frames - somewhat less durable than square ones.

double glazing

By analogy with a profile in a double-glazed window, its thickness is important. The minimum allowable parameter is 4 mm. At the same time, the profile must also withstand heavier, large tempered and shockproof glasses. So, in the modern Veka Softline 82 profile system, it is possible to install a double-glazed window with a thickness of 52 mm. For KBE in 88 mm systems (the name is given by the installation width) it is 52 mm, and with a rebate expander it is possible up to 58 mm (typical for 70 mm systems: Select, Expert, Expert+, Energy). In the Rehau Geneo model, the thickness of the double-glazed window is listed at the level of 53 mm, and with folds - up to 66 mm.

Physical characteristics of Veka, KBE, Rehau windows: similarities and differences

thermal insulation

The thickness of the frame and double-glazed window, seals and fittings directly affect what temperature will be kept in the room and whether you will have to overpay for electricity or heating. Index heat-shielding properties design is determined by the coefficient of resistance to heat transfer. The higher it is, the more comfortable you will feel in an apartment or house. The maximum possible indicator for individual Veka models is 1.04 m²C / W, KBE - 1.05 m² C / W, Rehau - 0.79 m² C / W.

Waterproofing

Waterproofing - important parameter when choosing a window. It is unpleasant when, during the rainy period, precipitation begins to seep into the room. To try to avoid this, it is worth specifying the material, the shape of the seals, the number of seal contours used in the profile. The sealant may not be the only reason for the appearance of moisture, icing of the window, since well-made installation of the structure is also important here. Today, manufacturers resort to the use of rubber, silicone, thermoplastic. Ethylene propylene rubber is a fairly versatile solution, since it is not subject to deformation, cracking during low temperatures. It is found in the products of our manufacturers. Veka has models with silicone seals, KBE has a thermoplastic.

As for the shape of the seal, they can be one- and two-petal. Petal - a part slightly separated from the product and resembling a tube. Veka and KBE profile systems have one lobe, Rehau has two, which is more practical, since there is no air opening in such a sealant, as a result of which moisture is not concentrated in the petals.

Life time

Companies that are fully responsible for the quality of their products, as a rule, prescribe their average operating life in the characteristics. It is formed on the basis of readings obtained during test experiments, when the structure is subjected to intense loads, largely “playing” with temperature, humidity, and pressure. As a result of these experiments, the following data were obtained:

• Veka and KBE guarantee 40 years of service life of the structure if they meet the requirements for quality and reliability and function in the usual normal mode;
• Rehau has 60 years of conditional operation.

External similarities and differences of products

All three manufacturers of plastic windows do not skimp on imagination and offer their customers a wide the lineup products that differ in functionality, shape and size, color and texture solution, the number of doors and the way they open / close, additional options and accessories. These parameters will form the final price of the window. From the point of view of the aesthetic component, all three manufacturers have succeeded in this matter, they have models of elegant outlines, interesting design solutions.

Caring for products made of plastic windows

Plastic windows are relatively easy to maintain. It is enough to wipe them from dust or adhering dirt with a damp cloth. For Rehau windows, this task is even more simplified: the absence of roughness allows you to increase the intervals between maintenance, since windows get dirty much less often.

Summing up

Correlating all of the above parameters, it is impossible to give leadership to any one company with confidence. Each of them is good in its own way. Thus, Veka is ahead of its competitors in terms of profile rigidity. In terms of sound and heat insulation properties, KBE does not lag behind it, which also uses the “greenline” technology, which excludes the use of heavy metals. Rehau windows are famous for their longer service life and improved waterproofing properties. Approximately at the same level, companies keep the brand for wide choice windows and their aesthetic appearance, providing a thorough quality control of their products, which are characterized by safety, environmental friendliness, resistance to drops temperature conditions. Therefore, the choice of the buyer should be individual based on his preferences, requirements, type of climate and financial capabilities.

When choosing a particular brand of profile, consumers always face a logical question: which profile for windows pvc is better Rehau or Veka, by what parameters to compare them to choose best option for a particular case? The article compares profiles according to the main parameters.

Windows Rehau and Veka: information about manufacturers

Rehau and Veka are well-known German brands of manufacturers metal-plastic profiles for windows. Both companies appeared on the Russian market at about the same time: Rehau in 1999 and Veka in 2002. Both manufacturers have a long history, practical experience, new developments and ongoing research.

It is impossible to give an unambiguous answer to the question “which plastic windows are better - Rehau or Veka”: each of the brands and lines is designed for certain requirements that differ in climate, requirements for operating conditions, and even wall material from which a building is constructed. Therefore, it is necessary to compare the main characteristics - the number of chambers, the thickness of the outer wall of the double-glazed window, physical properties, appearance and service life.

Number of cameras

The number of chambers determines the thermal conductivity of the window as a whole: the more chambers, the lower the thermal conductivity. For a 3-chamber window, the heat transfer resistance coefficient (KRT) is - 0.62, and for a 6-chamber window it is about 1. Comparing PVC windows Century or Rehau - which is better or worse in this indicator, it should be said that both profiles have models with a number of 3 to 6, but for VEKA Topline + with 4 cameras the coefficient is 1.37, and for 6-chamber REHAU Geneo-Design - 1.05.

Wall thickness comparison

When deciding which profile for plastic windows is better than Rehau or Veka, take a closer look at the thickness of the outer wall of the profile: the best value is 3 mm. This recommendation is strictly followed by the manufacturer VEKA, and REHAU is somewhat inferior, offering 2.7 mm instead of 3 in the budget lines Blitz and Delight Design.

Physical Properties

Are you thinking about the question “windows of the Century or Rehau: which is better to install”? Do not forget to compare the main physical parameters:

• thermal protection. For comparison, you need to look at the level of heat transfer. The coefficient has values ​​from 0.62 to 1.37 (Centuries). The higher this indicator, the better these properties;
• noise isolation is rated in decibels and for both manufacturers it has the same range - 30 - 36 dB;
• waterproofing. Provided by installing a gasket between the opening sash and the frame. This approach provides a barrier to the penetration of moisture and wind from the street. Materials for seals Veka and Rehau use the same, but the forms differ. Vek has a single-petal design, while Rehau has a 2-petal design, which is recognized by experts as more reliable.

Appearance and care

Standard models from both manufacturers are the same in their appearance and functions, but you should always keep in mind that Veka or Rehau plastic windows can be equipped with additional fittings and change their appearance using lamination.

In terms of care, both manufacturers have taken care to simplify it as much as possible. Windows and frames easily restore their original look using the most common detergents. Once a season, it is necessary to lubricate the hinges and locking mechanisms, once every 5 years - change the seals and lubricate them with a special silicone compound 2 times a year.

Service life and guarantee of profiles

The durability of the Rehau or Veka window profile is determined by the material itself - PVC, as well as additional reinforcement. Careful operation, the use of neutral detergents, regular maintenance play a significant role mechanical units. However, during testing, it was found that average term the service life of Veka windows is about 40 years, while Rehau is 60 years old.

comparison table

If a person asks the question: “Which windows to choose: Veka (Century), KBE (KBE) or Rehau (Rehau)?”, He, of course, is already familiar with the market for PVC profile window products, and knows that the above manufacturers occupy a leading position in the ranking of the most famous and sought-after companies both in the Russian and international markets.

It is impossible to decide unequivocally that one or another manufacturer is better, because a plastic window has a complex design, where constituent parts are: reinforcement, PVC profile, seals. Main operational properties profiles are: thermal 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, first of all, need from new windows: saving optimal microclimate at any time of the year, protection from extraneous noise from the outside, good level waterproofing, etc.

Technical characteristics of windows

1.1 Number of cameras in a profile

The air cavity that forms between the profile partitions is called the chamber. With an increase in their number, the temperature in the room also increases. Smallest number There are three cameras in the profile. In this case, the coefficient of resistance to thermal protection is on average 0.62. If the profile is four-chamber, the coefficient reaches 0.64, five-chamber - 0.68, six-chamber - 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 similar 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, noise 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 the category "A" of the Russian standard (2.5 - 3 mm).

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

1.3 The largest width of the double-glazed window

It is wrong to focus only on the profile, because the indicators of heat and sound insulation also depend on the thickness of the double-glazed window. Only a strong profile with a special design of the sashes can withstand a double-glazed window of good thickness.

The most stable profile of the Veka product line is “VEKA-alphaline”, it is able to withstand a double-glazed window up to 50 mm thick.

Among the KBE profiles, the most stable was KBE Expert - it can withstand a double-glazed window up to 58 mm thick.

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

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

Physical characteristics of windows

2.1 Window thermal protection

The level of heat-shielding properties of the profile is measured by KST (heat transfer resistance coefficient). 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 Window waterproofing

In homes, an unwanted “surprise” is always moisture. This is especially true for those areas where its concentration is high and without additional penetration from the outside, for example, kitchens, bathrooms. Waterproofing characteristics profiles entirely depend on the shape and quality of the seal (elastic gasket between the frame and the sash). Due to it, the tightest fit is achieved, thereby the room is protected from moisture and cold air. Signs of a bad seal are frost and condensation on windows.

To date, the most universal material for the production of the seal was EPDM (ethylene propylene rubber). It does not lose its properties at low temperatures, does not deform during compression, bending and stretching.

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

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

Veka seals, for the most part, are single-lobe. A petal is a sealing 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 seal has two petals, and there is no additional air space in it.

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 is the main material in the window manufacturing process. However, it is not able to withstand the pressure from the double-glazed window on its own and negative factors environment. Therefore, a PVC profile with a length of more than 500 mm, according to GOST, is subject to mandatory reinforcement. The reinforcing insert is metallic profile from galvanized tape (thickness 1.5-2 mm). The quality of this detail is largely influenced by its shape, it can be U-shaped and closed square. Qualitative characteristics this part depends on its shape.

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

2.5 External characteristics, complexity of maintenance 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 sash location, type of opening, receiving additional options: climate control, mosquito net, tinting, laminating, etc. This allows you to order a window not only of a suitable shape, but also suitable color, hue and texture.

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

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

2.6 Service life of windows

The durability of PVC profile windows is their main advantage. How can a customer find out the average service life of a company's products? 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, and humidity are often changed in the chamber. As a result of such a study, the life of the window is revealed. For the standard Veka and KBE profile, a period of 40 years was determined, the REHAU profile is much longer - 60.

2.7 Comparative characteristics of REHAU, Veka and KBE profiles

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

If we say in a nutshell about the differences in profiles based on customer reviews, then it will look like this:

• “The VEKA profile is of high quality and durable, its walls are thicker and it is generally well made, it has a noble white matte surface and 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 faked, has cheap Russian, Turkish, Chinese counterparts of rather low quality”;
• “KBE is a well-known brand on the market, but still inferior in quality 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 have become widespread in glazing country houses, balconies and apartments. Most of the VEKA window series have a low cost, which does not come at the expense of quality. It is also necessary to note the following parameters:

• Only used in production safe materials High Quality;
• Profiles have elegant outlines;
• The only profile in Russia of class "A";

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

REHAU plastic windows

Windows Benefits REHAU is better just look at the example of the most popular series - Rehau Basic-Design. This model has the following options:

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

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

Plastic windows KBE

KBE - are considered a classic brand of plastic windows. They are widely used due to the following criteria:

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

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

When purchasing housing in the secondary real estate market, or having inherited an apartment built during the Soviet Union, the owners face the question of a major overhaul of the house. Improving living conditions, as a rule, begins with the replacement of communications and windows. There is a huge choice of companies on the market of plastic profile systems, among which the leading positions are occupied by products of German manufacturers. Which is better: Veka or Rehau windows? It is impossible to answer unequivocally in favor of a particular company, however, having analyzed the characteristics and advantages of the goods of each manufacturer, it will be possible to make an objective choice.

Manufacturers

The window, as a finished product, reaches the customer after going through several links. At the first stage, there are companies that produce plastic profiles by extrusion. In everyday life, windows made from the profile of a particular company have its name, which indicates the importance of such a characteristic as PVC construction. Then the six-meter PVC structure goes to the processor, where it is converted into a finished window structure. Dealers, with whom the customer communicates before choosing windows and installing them, conclude an agreement with the processing plant on the supply of finished PVC profile systems. Although there are firms that independently manufacture plastic windows, acquiring only a profile for their production, and directly sell them to the customer, bypassing the dealer link.

It is important to understand that if we are talking about windows of European manufacturers, then this is an indirect sale of goods from Germany. For example, plastic windows "Veka" or "Rehau" are made from the same name. german profile on the territory of Russia under the license of the concern. And the profile is also produced locally at one of the company's production facilities.

Veka and Rehau: what do they have in common?

Which is better: Veka or Rehau windows, if both manufacturers produce a profile using German quality control. The history of the two companies begins in the 20th century. The first plastic profile in Rehau was implemented in 1958, after 10 years the competition was made by the company Veka. The main representative offices of the companies are located in Germany, and production facilities operate in Russia, Poland, Ukraine and other countries.

The only difference between the companies is that Rehau specializes not only in window and door profile systems, like Veka, but also in engineering communications, the supply of polymer systems for the automotive industry, and the production of components for the furniture industry.

With a small time difference, a representative office of companies appeared in Russia: first, Rehau in 1995, and in 1997, Veka. The first plastic extrusion plant in the Moscow region was opened by VEKA, in 2004 similar facilities were located in Novosibirsk. In 2002, Rehau opened a workshop for the production of plastic profile systems, and in 2003, construction of a plant began in Gzhel, which was completed by 2008.

Profile

Main constructive element a PVC profile is considered in the window, which on the cut is a contour with many partitions. The voids between the plastic walls are called chambers. The more air spaces, the higher the coefficient. Plastic window companies produce products from profiles, the minimum number of chambers in which is 3.

"Rehau" and "Veka" in the product line have window profiles from 3 to 6 cameras. Comparative table (information is objective and taken from official sources).

It is impossible to say from the characteristics of the profile which is better, the “Century” or “Rehau” windows, unless the analyst is an employee of one of the listed companies, since the technical indicators of identical profile series are the same.

Profile class

The outer frame of the profile according to the European standard must have a thickness for class A: 2.7 - 3 mm. Then it can be made facade structures and frame installations. If the profile walls are less than 2.7 mm, then the manufacturer saved on PVC, and such a profile belongs to class B, which has a service life less than its predecessor.

On the official resource, Veka plastic windows in the four-chamber version are declared with an outer wall thickness of 3 mm, there is no such information about the Rehau opponent. Although the competing sites provide an allegedly real (not declared by the manufacturer) characteristic of the thickness of the profiles of both companies 2.8 mm. It remains to hope for your own measurement when choosing windows.

double glazing

A large area of ​​the window opening falls on glass, so noise insulation and energy saving depend on its thickness and other characteristics. A double-glazed window consists of at least two glass panels, the space between which is filled with air. Single-chamber double-glazed window- at least two glasses. The thicker layered construction, the higher specifications window system: tightness, heat and sound insulation. Cameras in profile and in glass construction are different things.

• With polymer film are called triplex.
• Standard.
• Energy saving.
• Sun protection.
• With different glass thicknesses - soundproof double-glazed windows.

Rehau windows are installed using double-glazed windows with a thickness of 24 mm to 44 mm. In the profile "Century" there is technical possibility install glass structure thickness from 24 mm to 50 mm.

accessories

When choosing plastic windows, it should be understood that this design does not consist of one profile and glass. Mechanisms that open and close up to five locks at the same time with one turn of the handle are called fittings. A constant load is assigned to it, and the uniform fit of the sashes to the frame depends on the quality of the mechanisms.

Plastic window companies independently choose suppliers of window fittings. A burglar-proof window handle from REHAU is presented on the Russian market. Reliable fittings: hinges, trunnions, clamps are produced by the Austrian company MACO. Quality mechanisms for PVC windows also provide German firms Roto and SiegeniaAUBI. The listed accessories are capable of withstanding a load of 20,000 full cycles opening and closing windows. Standard windows "Veka" prices with installed German fittings are 65% higher than similar designs with Turkish or Chinese mechanisms.

Plastic windows for the house "Rehau"

Choosing a worthy filling of the window opening, it is necessary to take into account the natural and climatic conditions. Which Rehau windows are best for urban high-rise buildings? Professionals recommend stopping at windows with a profile 70 mm wide, for example, the SIB-DESIGN series. Soldered, with the fulfillment of all requirements, profile in window block does not leak and does not freeze, which is experimentally proven. The Delight series is suitable for northern apartments with a disadvantage natural light. The profile of this series is narrower than usual, due to which the light flux is increased by 10%.

What other features do Rehau windows have? The price of a construction with a size of 1400x1450 mm, with a double-glazed window, with a five-chamber SIB-DESIGN profile, without lamination is 9,350 rubles (without a window sill and ebb). Price profile system with the possibility of receiving additional light will cost the buyer, as of November 2015, 10,240 rubles. Since the Rehau windows have a variety of profile characteristics, there are also budget product options. standard window from the BLITZ category will cost 7,980 rubles.

Windows "Century": prices

To compare the pricing policy of both companies, the monitoring of Veka windows was based on determining the cost of a double-leaf product of similar dimensions, as for Rehau 1400x1450 mm.

Plastic window systems from the Euroline profile, consisting of three chambers with double glazing, will cost the customer 7,300 rubles. If the work will be carried out on a turnkey basis, then it is necessary to count on 13,600 rubles. The Proline window series, consisting of a four-chamber plastic system, is estimated by the manufacturer at 8,400 rubles. The cost of the window system from the five-chamber Softline profile is not much different from the similar Sib-Design series of the Rehau window. The price of the structure is 9,100 rubles. Comparing German brands for the production of basic elements for a plastic window by price, we can conclude that the pricing policy is loyal. The price of a standard double-leaf window (without window sills and ebbs) in Russia is on average 10,000 rubles.

Bottom line: which is better, Veka or Rehau windows?

If the reader has reached this section of the article, then he has an idea about all important elements and the details that make up complex structure plastic window. The profiles of the two brands being compared are top sellers. Both companies have production capacity on the territory of the Russian Federation, so there are no direct deliveries from Germany. The manufacturing technology of profiles at "Vek" and "Rehau" corresponds to all government requirements and European certificates.

The only difference plastic systems- the ability to accommodate a double-glazed window with a thickness of 50 mm. Here, with a small margin, the company "Veka" is in the lead. The service life of the windows depends on the fittings supplied by the manufacturer and the installation.

When choosing windows, it is important to entrust the installation of the structure to professionals. When signing the contract, it is necessary to check the information about the hardware manufacturer, if there is no data, then it is likely that the locks, handles, hinges will not meet the declared quality.

Both firms have long proven their competence as manufacturers. Both have developed and produced a wide range of profiles with different technical parameters. All designs 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 rate “good and bad” for each a separate parameter, and having decided what is more important in your case, buy windows from a specific manufacturer. To be as objective as possible, let's try to compare the designs of two well-known firms according to the main technical indicators, but ...

Whichever profile you choose, the amount of warmth and silence stored 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 double-glazed window.

Number of cameras

The PVC frame consists of many cavities separated from each other by partitions. These are the air chambers: the more there are, the less chance the cold has 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 structures with 3-6 cameras;
• in Rehau windows there are 3-5.5 of them (a half figure is associated with the design features of the profile. According to Russian standards, this equates 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 selection parameter.

External wall size

Width affects:

• on the ability of windows to retain more heat;
• for soundproofing;
• on the rigidity of the structure, its resistance to mechanical damage, deformation under the influence of a heavy double-glazed window.

The standards in force in Russia regarding 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 windows Rehau 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 the discrepancy accepted norms alarming.

Double glazing width

Warmth and silence are more dependent on the installed double-glazed window, more precisely on its thickness. To hold heavy weight for several decades, you need a frame of the right size and strength.

Conclusion: if the window is required 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 Comparison Specifications

Pay attention to:

• waterproofing: depends on the sealant, on its quality and shape. In this parameter, Rehau windows with two-lobe gaskets win, which are more practical, do not contribute to the accumulation of condensate, do not freeze and last 2-3 years longer;
• strength: to increase permissible load, the profile is reinforced with galvanized metal frame. The most rigid have a closed square shape. Such windows are produced by Veka. The competitor produces profiles on L or U-shaped frame. They are less stable;
• service life: experimentally proven that Rehau windows will last about 60 years, and Veka will have to be changed 20 years earlier.

Models with the highest heat transfer coefficient will provide an optimal atmosphere in the house. This category includes windows from Rehau - Delight-Design, Brillant-Design and Veka - Swingline and Softline.

If the apartment faces carriageway or there is an airfield nearby, a factory that emits a constant hum, give preference to designs with the widest double-glazed window. Vek has such - alphaline and topline +, and Rehau - Sib-Design.

When preference is given to design, color, tinting, shape of fittings and other parameters, one should be guided by one's own taste, general interior concept and price. By the way, according to this criterion, the models different firms no significant differences

REHAU or Veka - which one window profile better? There is no clear opinion. Focus on the metrics that matter most. If the second one is the leader in terms of sound insulation, heat saving, profile strength, then the first one is ahead in terms of sealing quality and durability.
