Which is better to choose rehau or century. Which profile is better Veka, Rehau or KBE? Choosing a Kaleo Age Rehau Profile

Among all the popular window profiles, VEKA and REHAU can be distinguished. It is these manufacturers that occupy the first lines of the ratings of the most famous and sought-after companies both in the Russian and international markets. A plastic window is a complex structure and it is impossible to unambiguously identify a leader, because some of the indicators among thermal protection, sound insulation, waterproofing, reinforcement, seals and PVC profile quality are better for REHAU, and some for VEKA.

Each has its own strengths, which must be relied upon and taken into account when choosing new windows. To do this, we determine the desired configuration and functionality: whether enhanced protection from external noise sources is needed, improved waterproofing, and how high-quality the thermal protection of the room should be.

Main characteristics of windows and profiles

The number of cameras in the profile.

A chamber is a hollow space between the profile partitions filled with air. The higher their number, the higher the room temperature. Usually 3 cameras are installed, this is the minimum allowable number. According to the number of chambers, the coefficient of resistance to thermal protection and the sound insulation index are calculated.

The profiles of VEKA and REHAU companies contain from 3 to 6 cameras; according to this indicator, the products are almost similar.

The width of the outer walls.

External walls determine the reliability and service life of the window, as well as its functionality. The level of thermal protection and sound insulation depends on the thickness, resistance to mechanical and physical stress, deformation is provided. According to GOST 30674-99, the wall thickness of the profile should not be less than 3 mm.

VEKA adheres to Russian and international standards, offering a profile with walls from 3 mm thick and above. No wonder it was VEKA products that became the basis of Russian window standards. REHAU, in order to reduce the cost of production, offers profiles with a smaller wall thickness - from 2.5 to 3 millimeters.

Glass pane width.

Not only the profile determines the performance of heat and sound insulation. It is necessary to take into account the thickness of the double-glazed window - the thicker it is, the better. But only profiles with special sash designs can withstand the high thickness of the double-glazed window.

The most stable profile of the VEKA line is VEKA-Alphaline, which can withstand a double-glazed window up to 50 millimeters thick. At REHAU, the strongest profile is REHAU Sib-Design with an indicator of only 44 millimeters.

Window thermal protection.

The heat-shielding properties of the profile are measured by the heat transfer resistance coefficient (KST). The higher it is, the warmer the room, since cold air does not penetrate inside.

To a greater extent it depends on the thickness of the double-glazed window: VEKA has 1.37 m 2 C / W, REHAU has only 0.79.

Waterproofing.

Moisture is always an unwanted guest in those areas where there is so much of it - kitchens, bathrooms, bathrooms. To ensure good waterproofing on the windows and prevent frost and condensation, elastic gaskets are used between the frame and the sash - seals. The tighter they fit, the better the room is protected from cold air and condensation.

Ethylene propylene rubber (EPDM) is a versatile material used by most window manufacturers. It does not deform when stretched, compressed and bent, and does not lose its properties at low temperatures.

At VEKA, single-lobe seals are mainly used, slightly separated from the product and similar in shape to a tube. REHAU has two petals and there is no additional airspace, due to which the service life is increased by 3-4 years.

Strength.

According to GOST, PVC profiles above 50 centimeters must be reinforced, since plastic without additional materials is not able to withstand the pressure of a double-glazed window and the environment. The insert is a galvanized metal tape 1.5-2 mm thick. Both can be square and U-shaped, the quality depends on its shape.

VEKA uses a square-shaped reinforcement in most profiles, for REHAU various options are allowed, in particular G-shaped. It is stronger than a square profile, but worse in terms of rigidity and stability.

External and operational characteristics.

VEKA and REHAU companies offer a wide range of window profiles, among which everyone can find something that satisfies in terms of functionality and external characteristics. You can choose a window of the optimal size, shape, color, shade and texture, and in terms of aesthetics, VEKA and REHAU are not inferior to each other.

Additional features are also provided: the choice of the location of the valves, lamination, climate control, mosquito net, toning, the choice of the type of opening.

PVC does not require special care and all that is required from window owners is to wash and wipe them periodically. REHAU has a smoother part of the profiles, which further simplifies the operation process.

Installation of plastic windows is an excellent solution of modern design, which provides comfort both at home and at work. Such windows provide reliable heat and sound insulation. But, in order for these functions to be performed with high quality, it is necessary to choose plastic windows from a good manufacturer, as well as install them in full accordance with the technological requirements.

The first stage of installation of plastic windows "Rehau"

Rehau energy-saving windows (reviews of people confirm this information) are quite difficult to install, but if all technological recommendations are followed, this process can be carried out even by a beginner in this business. The steps for installing windows are as follows:

measure the opening and order a window in a specialized organization;
dismantle old windows;
prepare and process the opening for the installation of the profile;
install and fix PVC windows "Rehau".

Feedback from those who have already performed such work indicates that measurements must be carried out with special care and thoroughness. Otherwise, the profile will be made with incorrect parameters and may not fit the opening.

In order to obtain the desired parameters, it is necessary to measure the height and width of the window separately with a tape measure outside and inside the room. Measurements are taken in different places, since the opening may be skewed, and the smallest of all the values obtained is taken as a basis. Then measure the parameters of window sills and slopes. Before ordering windows, you need to decide on the design and style, color, technical parameters, shape, number of partitions, and so on.

Before buying, many are wondering which windows are better - "Century" or "Rehau". Consumer reviews indicate that the latter provide a much larger selection of their products according to various criteria.

If a new window is inserted to replace the old one, then the latter is dismantled and the window opening is thoroughly cleaned.

The second stage - installation of windows

The second stage can be done in two versions:

First, dismantle double-glazed windows with hinged sashes. Using a metal drill on the window frame on the inside, make holes for attaching the window according to the following scheme: two - on top, three - on the sides, two - on the bottom. Fix the window with anchors.
Some models have already built-in special fasteners - they are attached with screws to the window frame.

In order to properly mount the Rehau windows (reviews from practitioners say so), wooden blocks are laid in the middle of the window sill, on which the frame is installed. Then fasteners or anchors are mounted in the window opening.

After that, the horizontal position of the window is checked with a water level, and the correct vertical installation is determined with a suspension. Only after carefully checking these parameters, proceed to the next step.

The third stage - fixing the profile

Most often, customers are satisfied and praise Rehau plastic windows, negative reviews are found only when the profile installation technology is violated.

Windows are fixed in two ways:

With the help of a frame. Holes are made in the wall with a puncher through which the lower part of the frame is attached. Then, after checking the verticality, the upper and middle parts of the window are fastened.
With the help of plates. Special metal plates protruding from the top and bottom of the window are fastened tightly to the wall with a ladder. Then, first, the lower part is strengthened with a puncher, and then the upper and middle parts.

The geometrically correct position of the window structure must be checked at each step of the installation.

Final step

At the last stage of window installation, drainage is installed, double-glazed windows and additional sashes are installed.

The gap between the window system and the opening is sealed with polyurethane foam. To prevent the foam layer from collapsing due to temperature changes and under the influence of moisture, a hydro- or vapor barrier film is attached.

Many customers confirm that Rehau windows have excellent technical characteristics. Reviews also indicate that the profiles of this manufacturer are equipped with the best fittings compared to others. But still, sometimes it becomes necessary to repair or adjust them. The reasons for this may be the following:

poor-quality, in violation of technology installation of windows;
long-term use and wear of the window system;
insufficiently tight connection of the sash and frame, which leads to excessive heat loss;
low degree of sound insulation;
sagging window sash.

Adjustment of the plastic system "Rehau"

When a client is faced with a choice - plastic windows "Newton" or "Rehau", reviews, as a rule, advise the latter. And this is due, among other things, to the ease of adjustment.

The main methods for adjusting Rehau plastic systems:

The sashes are brought with a hexagon depending on the season: in summer - a loose fit, in winter - vice versa.
Incorrect installation or bevel of the frame is adjusted by a couple of millimeters with a hexagon in the holes on the window hinges by turning it clockwise. Similarly, vertically - with a hexagon in the lower hinged loop.
With a loose seal, tighten the bolts with the sash open.
If the window creaks, the seal is lubricated with silicone oil. Similarly, if the handle creaks or is tight.
If the window handle sticks, it means that the moving elements of the system have dried up or the sash has sagged. First, lubricate the mechanism, and if it doesn’t help, adjust the window hinges with a hexagon by tightening the adjusting screw with the sash open perpendicular to the window frame.

In order for plastic windows of any manufacturer to serve for a long time and not fail, you should regularly inspect them, replace worn parts, and also systematically clean them, especially the seal. After all, small particles of dirt and dust undoubtedly affect the performance and condition of plastic systems.

And "Veka" took a leading position in the Russian market due to impeccable German quality and attractive price. They are manufactured at its base in Russia by the Plastek company. To answer the question which windows from these two brands are right for you, you should study in more detail the design and properties of windows from both manufacturers.

The main differences between the two competitors are Rehau and Veka.

It is very difficult to say unequivocally which windows of which manufacturers are better and which ones are slightly inferior to competitors. Much depends on the profile of the structure, consisting of several elements. Usually the construction consists of PVC, reinforcement and sealant. The main properties of plastic windows are saving heat in the winter season, sound and noise insulation, as well as waterproofing the room. According to some window parameters, Veka bypasses its main competitor, Rehau, and vice versa. In order to make the right choice in favor of one or another manufacturer, it is worth determining what is more important for the buyer: to achieve maximum silence or save on space heating, or can achieve perfect waterproofing?

Technical characteristics of a plastic window from the German brands "Veka" and "Rehau".

Window manufacturers "Veka" and "Rehau" produce double-glazed windows that look similar to each other, but they radically differ in the profile walls on the outside of the product, the number of chambers on the profile and the width of the package.

camera inside the window "Rehau" and "Century". - this is the space between the partitions. The level of heat depends on this characteristic. The more cameras, the warmer the building.

Differences in the design of the manufacture of windows "Century" and "Rehau".

Company "Rehau" manufactures double-glazed windows with a minimum of three chambers, the maximum number is 5.5. This figure appeared due to an additional iron partition. According to Russian law, such a partition is considered complete, but the company's management decided to designate its windows in this way so as not to mislead customers. The only difference in these characteristics of Veka windows is that they have 6 full-fledged cameras.

Differences in the outer wall of the PVC window profile from the German manufacturers "Veka" and "Rehau".

This indicator determines the wear resistance of German windows. According to the domestic standard, the outer wall should be made of a 3 mm profile or thicker.

Company "Veka" produces exclusively German windows only with a profile of more than 3 mm. The Rehau company is skeptical about this indicator, manufacturing window structures with a thickness of 2.7 mm, thereby taking care of the wallets of its potential buyers. Maximum width of Rehau and Veka plastic windows.

Noise and thermal insulation depends on the width of the profile. German windows "Veka", which are produced by Plastek, created the Alphaline profile. To date, it is recognized as the most stable among the wide range of products of this brand. Its thickness is 50 mm. The main competitor, the Rehau brand, manufactures plastic profiles with a maximum thickness of 44 mm.

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 stages. 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 German profile of the same name in 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

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. 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).

Profile Series	Number of chambers, pcs	Mounting width, mm	Heat transfer resistance coefficient, m2S/W

Euroline
Softline
Alfaline

Euro design
Sib design

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 facade structures and frame installations can be made from it. 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. A single-chamber double-glazed window is at least two glasses. The thicker the multilayer structure, the higher the technical characteristics of the window system: tightness, heat and sound insulation. Cameras in profile and in glass construction are different things.

with a 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 Veka profile, there is a technical possibility to install a glass structure with a thickness of 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. High-quality mechanisms for PVC windows are also provided by the German companies Roto and SiegeniaAUBI. The listed fittings are able to withstand a load equal to 20,000 full cycles of 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, the profile in the window unit does not leak and does not freeze, which has been experimentally proven. The Delight series is suitable for northern apartments with a lack of 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). 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 a variety of profile characteristics, there are also budget product options. A 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 the German brands for the production of the main elements for a plastic window by price, we can conclude a loyal pricing policy. 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 the important elements and details that make up the complex design of a plastic window. The profiles of the two brands being compared are top sellers. Both companies have production facilities in the Russian Federation, so there are no direct deliveries from Germany. The manufacturing technology of Veka and Rehau profiles complies with all state requirements and European certificates.

The only difference between plastic systems is 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, the specific properties of which determine the characteristics, quality, beauty, and service life of the finished product.

It is more correct to rate “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 ...

Whatever 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 of them, 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:

the Veka company produces window structures with 3-6 chambers;
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 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 accepted standards is 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 requires maximum protection from the cold, choose the appropriate 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 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 the load capacity, the profile is reinforced with a 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: it has been experimentally proven that Rehau windows will last about 60 years, while Veka windows will have to be replaced 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 overlooks the roadway or there is an airfield nearby, a factory that emits a constant hum, give preference to designs with the widest double-glazed windows. 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 of different companies do not have significant differences.

REHAU or Veka - which window profile is 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.
