Interview rehau veka. Comparison of REHAU and Veka window profiles - which windows to choose? Comparison of wall thickness

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 specific 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 stored in the house will depend on professional installation. Handicraft work will spoil the highest quality product, no matter how many chambers there are in the profile and in the glass unit.

Number of cameras

The PVC frame consists of many cavities, separated from each other by partitions. That's what it is air chambers: the more there are, the less chance the cold has to penetrate into the room, which means that the warmth 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 chambers;
• in the Rehau windows there are 3-5.5 of them (the half indicator is associated with the design features of the profile. 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 window profiles Rehau 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. Supporting heavy weight for decades requires a frame of the right size and strength.

Conclusion: if maximum protection from the cold is required from the window, choose a suitable design among the Veka profiles. 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 last for 2-3 years more;
• strength: to increase permissible load, the profile is reinforced with a galvanized metal frame. The most rigid ones have a 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 changed 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 or a plant nearby, 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 window profile is 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 saving, profile strength, then the first is ahead in terms of sealing quality and durability.

Choosing from all the variety, you often hear statements that windows from the Veka profile are better than PVC windows from Rehau. Is it so? - We invite you to figure it out for yourself, based on their main differences.

The surface of the VEKA profile, in comparison with the surface of the REHAU profile, has a more matte finish, which ensures, even after several years of operation of the plastic window, an impeccable look. Such a window will not capture your fingerprints, and in case of abrasion of the surface, the abrasion will not be noticeable.

Sealant

The location of the seal in the frame, sash and glazing beads of the product is made taking into account the need for tight pressure and, at the same time, invisibility from the side. The angle of inclination of the seals to the horizontal plane provides a more accurate and aesthetic appearance, in full compliance with the requirements for class "A" window constructions.

In our production we use only original seals recommended for installation in modern Euro windows that meet the conditions of the harsh Russian winter.

Internal structure of the profile

The PVC profile is a hollow structure with internal stiffening ribs. Thanks to the obligatory standard of the VEKA company, all the profiles produced by the enterprise correspond to the highest class "A" in terms of the thickness of the outer walls, as well as the specified geometric parameters.

The reinforcement installed in the central chamber of the Veka plastic profile, in contrast to the reinforcement in the frame of the REHAU plastic window, has a closed loop (in the shape of a square), which ensures high strength of the finished product and compliance linear dimensions... Convenient fastening of the frame in the opening and its reliable fixation is also a significant advantage when comparing the windows of the considered profile systems.

Other important parameters to compare

In order for the comparison to be made on identical systems, it is important to mention that manufacturers, both Rehau and Veka, release several different types profiles - the so-called series. These same series can be roughly divided into clear classes: design, universal, standard, premium.

Design - the simplest and, accordingly, the most inexpensive. Among them distinctive features- the presence of the minimum permissible number of internal chambers (3) and the minimum width (less than 70 mm).

Universal - suggest them effective use in most modern multi-storey residential buildings, offices and other civilian facilities.

Standard - type series, which meets the high requirements for thermal insulation and therefore, are more widely used in the case of private glazing projects for country houses and objects with passive heating.

Premium - ultra systems High Quality heat conservation and insulation. They are used in facilities where heat conservation is a key selection factor.

Conclusion

In conclusion, we would like to note the fundamental similarity in terms of quality characteristics Veka and Rehau profiles from the same "class" category. Therefore, in pursuit of a cheaper window from the REHAU profile, take into account the fact that this window can be made from a lower REHAU profile. The same is true for inexpensive VEKA windows.

Are you having difficulty making a choice? - Call us on the phone and get an instant answer!

Buying housing on the secondary real estate market, or having inherited an apartment built during the Soviet Union, the owners face the question of overhaul at home. The improvement of living conditions, as a rule, begins with the replacement of communications and windows. On the market of plastic profile systems huge selection firms, among which the leading positions are held by products German manufacturers... Which is better: "Century" or "Rehau" windows? It is impossible to unequivocally answer 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 passing through several links. At the first stage, there are firms 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 characteristics as PVC construction. Then the six-meter PVC structure goes to the recycler, where it turns into a finished window structure. Dealers, with whom the customer communicates before choosing windows and installing them, conclude an agreement with a processing plant for the supply of ready-made PVC profile systems. Although there are firms that make their own 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 in question about windows of European manufacturers, this is an indirect sale of goods from Germany. For example, plastic windows "Veka" or "Rehau" are made of 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.

"Century" and "Rehau": what do they have in common?

Which is better: "Veka" or "Rehau" windows, if both manufacturers produce profiles using German quality control. The history of the two companies begins in the 20th century. The first plastic profile in "Rehau" was realized in 1958, 10 years later the company "Veka" was competing. The main 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, the production of components for the furniture industry.

With a slight 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 shop for the production of plastic profile systems, and in 2003 the construction of a plant began in Gzhel, which was completed by 2008.

Profile

The main structural element in the window is considered to be a PVC profile, 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. Firms of plastic windows produce products from profiles, the minimum number of chambers in which is 3.

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

Profile Series	Number of cameras, pcs	Mounting width, mm	Heat transfer resistance coefficient, m2С / W
Euroline
Softline
Alphaline
Euro design
Sib-design

From the characteristics of the profile, it can be said unequivocally that it is better, the "Century" or "Rehau" windows cannot be, unless the analyst is an employee of one of the listed companies, since the technical indicators of identical series of the profile 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 you can make from it 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 shorter service life than its predecessor.

On the official resource, Veka plastic windows in a series with a four-chamber design are declared with an outer wall thickness of 3 mm, there is no such information about Rehau's opponent. Although on competing sites, the allegedly real (not declared by the manufacturer) characteristic of the thickness of the profiles of both firms is 2.8 mm. There is still hope for your own measurement when choosing windows.

Glass unit

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

• with a polymer film are called triplex.
• Standard.
• Energy saving.
• Sunscreens.
• With different thicknesses of glass - 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 capability install a glass structure with a thickness of 24 mm to 50 mm.

Fittings

Choosing plastic windows, it should be understood that this structure 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. She is entrusted with constant load, and the uniform adhesion of the sashes to the frame depends on the quality of the mechanisms.

Firms of plastic windows independently choose suppliers window fittings... On Russian market the burglar-proof window handle of the company REHAU is presented. Reliable fittings: hinges, pins, clamps are produced by the Austrian company MASO. High-quality mechanisms for PVC windows are also provided by the German firms Roto and SiegeniaAUBI. The listed fittings are capable of withstanding a load equal to 20,000 full cycles of opening and closing windows. The prices for standard "Veka" windows with installed German fittings are 65% higher than similar designs with Turkish or Chinese mechanisms.

Plastic windows for the house "Rehau"

When choosing a decent filling of a window opening, it is necessary to take into account the natural and climatic conditions. Which Rehau windows are better for urban high-rise buildings? Professionals recommend staying on windows with a 70 mm wide profile, for example, the SIB-DESIGN series. Soldered, with the fulfillment of all requirements, the profile in window block does not leak and does not freeze, which has been experimentally proven. The Delight series is suitable for northern apartments with a shortage 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 glazing, from five chamber profile SIB-DESIGN, without lamination is 9 350 rubles (without a window sill and low tide). The cost of a profile system with the possibility of obtaining additional light will cost the buyer, as of November 2015, 10,240 rubles. Since the "Rehau" windows have various profile characteristics, there are also budget options products. Standard window from the BLITZ category will cost 7,980 rubles.

Windows "Century": prices

To compare the pricing policy of both firms, the monitoring of Veka windows was based on determining the cost of a double-leaf product of the same 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. A series of Proline windows, consisting of a four-chamber plastic system, was estimated by the manufacturer at 8,400 rubles. The cost of a window system from a five-chamber "Softline" profile is not much different from a similar "Sib-design" series of a "Rehau" window. The construction price is 9,100 rubles. Comparing German brands for the production of basic elements for plastic windows by price, we can conclude about a loyal pricing policy. The price of a standard double-leaf window (without window sills and ebb tides) in Russia is on average 10,000 rubles.

Bottom line: which is better, the "Century" or "Rehau" windows?

If the reader has reached this section of the article, it means that he has an idea of ​​all the important elements and details that make up complex construction plastic window. The profiles of the two brands being compared are the top sellers. Both companies have production facilities in the Russian Federation, so there are no direct deliveries from Germany. The technology of manufacturing profiles at "Vek" and "Rehau" meets all state requirements and European certificates.

The only difference between plastic systems is the ability to place a 50 mm thick double-glazed window. Here, by a small margin, the Veka firm is in the lead. The service life of the windows depends on the fittings supplied by the manufacturer and on 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 manufacturer of the fittings, if there is no data, then there is a high probability that the locks, handles, hinges will not correspond to the declared quality.

Or Veka is quite difficult, since these manufacturers are widely known, popular, occupy leading positions and produce PVC profiles High Quality.

It is difficult to say that the products of one company are better or better than another. It all depends on the technical parameters of the profile, which is a structure consisting of several elements. The structural parts of the profile include PVC, sealing and reinforcement. The main operational properties of the profile are:

• soundproofing;
• waterproofing;
• thermal protection.

Some parameters are better in Veka and others in Rehau. To make a choice, first of all, you need to decide what you want from new plastic windows. For example, you want to ensure maximum quietness in a room, strive for minimal heat loss, or prefer windows with high waterproofing rates.

Technical parameters of plastic windows

Externally similar plastic windows may differ in the number of profile chambers, the width of the outer profile wall, and the maximum width of the glass unit.

Number of cameras in a profile

The chamber inside the profile is a volumetric space that is formed in the middle of the partitions. Therefore, the temperature level in the room depends on the number of chambers. The room in which the window with the maximum number of cameras is installed will be warmer. The minimum number of chambers is 3, and their thermal protection coefficient is approximately 0.62.

In a 4-chamber profile, this coefficient is increased to 0.64, in a 5-chamber profile - to 0.68, and in a 6-chamber profile - to 0.72. The profile, which consists of three chambers, drowns out approximately 15-20 dB, while each subsequent chamber increases this figure by another 8-10 dB.

Veka manufactures a high quality profile, which consists of 3-6 chambers, and Rehau - from 3 chambers to 5.5. Confused by the figure 5.5? There is nothing to worry about, since the profile design is slightly different. The iron insert, which is located in the center of the Rehau profile, is deliberately biased to the side. Consequently, the special position of the reinforcement adds another air baffle. If we rely on Russian standards, then this partition and the space formed is considered to be a full-fledged camera. But profile manufacturers position their windows as 5.5-chamber or 5 (6).

Both firms offer a similar range of windows in terms of the number of chambers in the profile. Therefore, determine on specific choice based on this parameter alone, it is almost impossible.

Profile outer wall width

This indicator determines not only the heat and sound insulation properties of windows, but also their resistance to mechanical stress and deformation. According to GOST, it is recommended to make the outer wall of the profile with a thickness of at least 3 mm.

Veka company does not produce window profiles in which the wall thickness is less than 3 mm. The manufacturer does not save on this indicator, and also carefully and responsibly follows international requirements and standards.

The Rehau company is more loyal to this issue, and produces profiles with thinner walls, the thickness of which ranges from 2.7 mm and more. These windows are intended for budget-conscious buyers.

Maximum width of a double-glazed window

The level of thermal protection and sound insulation depends not only on the profile, but also on the thickness of the glass unit. Installation of a double-glazed window with a maximum thickness is possible if there is a special profile that has high strength, as well as a specific sash design.

The VEKA Alphaline profile is the most sustainable among the Veka product line. It is able to withstand the weight of a glass unit, the thickness of which is 50 mm. At REHAU, the maximum width of a glass unit does not exceed 44 mm. This indicator is possessed by the REHAU Geneo-Design window model.

Based on the indicator of the maximum width of the double-glazed window, it can be concluded that Veka windows have higher parameters of heat conservation and sound insulation. Thus, the maximum level of the coefficient of resistance to heat transfer in the Rehau profile is 1.05, and in the Veka profile - 1.37.

Physical properties of plastic windows

Windows can have the following physical properties: heat insulation, sound insulation, waterproofing and some other properties.

Soundproofing and heat-shielding properties

The indicators are considered together as they depend on the same parameters and characteristics of the profile. The coefficient of resistance to heat transfer determines the heat-shielding properties of the window, therefore, the higher the coefficient, the more heat is retained and less through and cold flows seep into the room. The KST indicator is determined by the ratio of the temperature in the extreme parts of the profile to the density of the air that forms inside the profile.

Noise and sound levels are measured in decibels. The most soundproof windows are those that muffle outside sounds from the street.

Waterproofing plastic windows

In rooms where humidity levels are increased, it is necessary to install windows that maximally protect the room from the penetration of additional moisture from the street. For example, bathroom, kitchen. The waterproofing properties of a profile directly depend on the shape and quality of the sealant used.

The seal is an elastic gasket that is located between the frame and the sash. It promotes a tighter fit, and also reliably protects the room from permeable cold and moisture. If a low-quality seal is used in the manufacture of windows, then later condensation and ice may appear on the windows.

Today, a practical and practical sealant is used as a seal. universal material- ethylene-propylene rubber. The main properties of the material are:

• frost resistance;
• lack of tendency to deform when bending and squeezing;
• long service life.

Seals made by Veka and Rehau are identical, since they use the same material in their production. In addition, the seals are of excellent quality.

The shape of the seal will help you decide in favor of a particular window profile. The Veka firm produces a one-leaf seal, which resembles a tube in shape. The petal is a part of the seal that is located separately from the product.

The standard Rehau type seal consists of two petals, between which there is no additional gap. In the course of experiments, it was found that the shape of the seal, which is manufactured by Rehau, is more practical and reliable. Thanks to the shape, condensation does not accumulate in it, and it does not freeze and does not wear out for many years.

If you make a choice in terms of waterproofing properties, then the undoubted winner is the Rehau plastic window.

The strength and shape of the profile structure

Plastic cannot alone withstand the weight of a glass unit, negative impact environment... In this regard, a window profile that is made of PVC and has a length of more than 500 mm must be reinforced.

For reinforcement, a metal profile is used, made of galvanized 2 mm tape. The shape of the tape can be in the form of a square, the letter P. The firm of the Veka uses a square tape, and Rehau - a profile of a square shape or in the shape of a letter G. This profile stronger than a U-shaped profile, but incomparable with a square structure in terms of reliability and rigidity.

Thanks to modern developments, Rehau has managed to create a unique plastic profile, reinforced in bulk. This was made possible thanks to the use of the innovative RAU-FIPRO fiber material, which has incredible strength and resistance to stress. Refusal of steel reinforcement, allowed to reduce the total weight of the window structure by 40%.

Maintenance conditions and appearance of windows

Plastic windows are presented by both companies in a huge range and functionality. Customers are offered a choice of windows that have different opening methods, sash arrangements, and also have additional capabilities. For example, mosquito net, climate control and others. Moreover, each firm produces products in different shapes, colors and textures. If we consider the external characteristics of the firms Rehau and the Century, then we can conclude that they are on the same level.

Plastic windows are very easy to clean. To keep them clean, it is enough to wash them several times a year with water and a cleaning agent. Rehau decided to make it easier to care for its products. She makes a profile that has a perfectly smooth surface, PVC substances are so close that it is impossible to see the smallest flaws with the naked eye. Thanks to this, the profile is much less dirty.

Service life of windows

To reveal maximum term service of a plastic window, it is placed in a special chamber of "accelerated time". It recreates a powerful load that simulates decades. At the same time, it constantly changes temperature regime, humidity level and pressure. In the course of the experiments, it was revealed that the Veka windows can last up to 40 years, and the Rehau windows - up to 60 years.

Comparison of Rehau and Veka windows

Profile model	Glass unit thickness	Number of cameras in profile	Coefficient resistance heat transfer
REHAU Basic-Design	30-35 mm	3	0.62
REHAU Euro-Design	30-35 mm	3	0.64
REHAU Thermo-Design	30-35 mm	4	0.67
REHAU Sib-Design	35-44 mm	4	0.72
REHAU Brillant-Design	35-41 mm	5(6)	0.79
REHAU Delight-Design	35-44 mm	4	0.74
REHAU Geneo-Design	35-44 mm	6	1.05
VEKA Euroline	35-42 mm	3	0.64
VEKA Softline	35-42 mm	5	0.78
VEKA Topline	35-42 mm	5	0.74
VEKA Proline	35-42 mm	4	0.75
VEKA Swingline	35-42 mm	5	0.77
VEKA Alphaline	35-50 mm	6	0.94
VEKA Topline +	40-44 mm	4	1.37

Based on the technical parameters of the profile, it is impossible to determine the winner, since the Veka windows are the leader in thermal insulation, strength and rigidity of the structure. Rehau windows, in turn, have a high-quality seal and can be used much longer.

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

Rehau and Veka windows: information on manufacturers

Rehau and Veka are well-known German brands of manufacturers of 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 intended for certain requirements, differing in climate, requirements for operating conditions and even wall material from which this or that building is built. Therefore, the main characteristics should be compared - the number of chambers, the thickness of the outer wall of the glass unit, 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 coefficient of resistance to heat transfer (KST) is 0.62, and for a 6-chamber window it is about 1. Comparing PVC windows Veka or Rehau - which is better or worse in this indicator, it should be said that both profiles have models with the number from 3 to 6, but for VEKA Topline + with 4 cameras, the coefficient is 1.37, and for 6-chamber REHAU Geneo-Design - 1.05.

Comparison of wall thickness

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 Blitz and Delight Design lines.

Physical properties

Thinking about the question "Windows of the Century or Rehau: which is better to install"? Don't forget to compare the main physical parameters:

• heat protection. For comparison, you need to look at the level of heat transfer. The coefficient has values ​​from 0.62 to 1.37 (Century). The higher this indicator, the better the specified properties;
• noise insulation is estimated in decibels and for both manufacturers 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 moisture and wind penetration from the street. Materials for seals Veka and Rehau use similar ones, but the shapes differ. Vek has a one-petal design, and 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 appearance and function, but it should always be borne in mind that plastic windows of the Veka or Rehau can be retrofitted with additional fittings and change the appearance using lamination.

In terms of care, both manufacturers have taken great care to keep it as simple as possible. Windows and frames are easy to restore original view 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, and regular maintenance of mechanical components play a significant role. However, during testing, it was found that average term the service of the windows of the Century is about 40 years, while the Rehau - 60 years.
