Window profile KBE (KBE): types and technical characteristics

Plastic windows KBE

developed by the German company Kunststoffproduktion fuer Bau und Elektrotechnik (KBE), which began its journey in 1980. After five years of research, the first profile system was released to the market. In Russia, this brand first appeared in 1995, after which the popularity of this PVC profile began to grow steadily. The high reputation of KVE is already evidenced by the fact that all Russian “window” GOST standards in 1997-1999 were created with the direct participation of KVE specialists. Even now, these GOSTs are mostly illustrated with diagrams, drawings and cross-sectional drawings of KVE profile systems.

KBE plastic windows for Russian consumers are currently produced by two factories, which are located in Voskresensk (near Moscow) and Khabarovsk. Manufactured products are distributed through a developed network of branches and dealers, due to which delivery deadlines for these systems are strictly observed.

In addition, KBE has a principled approach to training its dealers. Special training and seminars on new products and technologies are provided for them; dealers have a constant opportunity to visit the research laboratory and production in order to become more closely acquainted with the aspects of the production of profile systems. And only dealers who have proven themselves in terms of compliance with all KBE standards and who have undergone full comprehensive training are considered full partners and receive their own “KVE Quality Control Certificate,” which is a guarantor of the quality of the products supplied by this partner.

Plastic windows KBE

were among the first to be produced using the “greenline” technology, that is, instead of lead in the production of PVC profiles, CaZn began to be used - calcium-zinc, a safe and environmentally friendly compound. Such a replacement, in addition to not harming the environment during the production and disposal of the profile, also significantly improves the properties of the material. It becomes significantly more weather resistant, which increases its durability. And the ability to use reinforcing liners in each profile system significantly increases the strength of window structures. The highest quality of KBE profile systems is confirmed by the international certificate ISO 9001.

PVC profile KBE Etalon

Plastic windows KBE Etalon

— this classic window system has existed on the Russian market for more than 15 years, which indicates its undoubted popularity and demand. Over the years, all aspects of the production, assembly and maintenance of these windows have been brought to perfection. Therefore, if you are looking for a reliable and inexpensive window, then this is your choice.

It is no coincidence that KBE Etalon windows are called the classics of plastic windows! This is one of the very first profiles to appear on the market. In Russia, they have been used for glazing windows for more than 15 years, and during this time, the developers and engineers of the KBE company have brought it almost to perfection, and still continue to refine and improve its characteristics.

Technical characteristics of KBE Etalon windows:

• Three-chamber profile design with heat transfer resistance coefficient R=0.63m2C/W;
• Mounting profile width 58 mm;
• Double-glazed window thickness up to 34 mm;
• The maximum sash size is 1500 mm x 1500 mm.

Advantages of KBE Etalon windows:

KBE Etalon windows are universal - they can be used to glaze any objects in any climatic conditions.

The main advantages of KBE Etalon include the following:

• Excellent noise and heat insulation. For example, sound insulation is up to 46 dB, which is almost 80% of the normatively accepted street noise in a metropolis.
• KVE Etalon windows meet environmental requirements because they do not contain lead, they are even recommended for installation in children's and medical institutions.
• The durability of these windows is up to 40 years! At the same time, they do not lose their whiteness, technical and quality characteristics.
• One of the clear advantages of KBE Etalon windows is their aesthetics and beauty. The profile has a rounded edge, which makes it look more attractive; in addition, they have one secret - they can visually enlarge the window opening by using a gray seal rather than black.
• And finally, with high consumer and performance qualities, KBE Etalon windows are one of the most affordable not only among KBE systems, but also on the market as a whole.

Thermal protection and sound insulation of windows

These indicators depend on the profile itself and the thickness of the frame. A better quality package will be able to withstand the heaviest and thickest profile. The most reliable Veka profile is Alfaline, which holds glass units up to 50 mm. "KBE" 88 - up to 58 mm.

KBE has better noise and frost protection data than Veka.

The heat transfer coefficient is an important indicator that is formed from the ratio of the temperature at the edge of the frame to the air density inside the chamber. The higher the coefficient, the warmer the room will be, that is, the less cold the package lets in.

The thermal insulation parameters of windows depend on the quality of the seal. A good material for making seals is rubber. It is not damaged by cold, water or stress. Both companies use this seal, but also use TPE; it is produced together with the window profile and is characterized by high thermal insulation.

Veka seals are single-lobe. The petal is an element that is not very separated from the frame. These seals are in the shape of a tube. The same form of seals is used at KBE. Rehau has 2 petals and is not equipped with additional air space.

The quality of the Rehau seal is higher, since the petals do not collect moisture, which means condensation will not appear on the windows. The service life of this seal is 3-4 years longer than in other modifications. Thus, it can be noted that Rehau is more functional in terms of waterproofing and thermal insulation.

PVC profile KBE Engine

Plastic windows KBE Engine is the most popular window system in the 58 mm line at an affordable price category. It allows you to produce windows and doors of any configuration (round, triangular, trapezoidal and others), which can be installed both in apartments and country houses. The German reliability of KBE products is combined with an attractive price for consumers of any level and income. In addition, this profile system has a number of undoubted advantages characteristic of PVC KVE windows.

Positive aspects of KBE Engine:

• environmental friendliness - lead-free production using “greenline” technology;
• thermal insulation - the tightness of the seal along the contour and the possibility of combining with a wide frame perfectly solve the problems of “cold bridges”;
• durability - profile service life is more than 40 years;
• more light - the light transmittance of double-glazed windows in plastic windows is much higher than in old windows.

The use of a rebate expander allows the use of a 50 mm thick glass unit in the KBE Engine window system, which significantly increases sound insulation and reduces heat transfer. The calcium-zinc stabilizer makes KBE plastic windows not only environmentally friendly, but also has a beneficial effect on the preservation of the decorative properties of the PVC profile - it does not lose its whiteness and silky matte texture. KBE Engine plastic windows are a smart financial investment to save overhead costs.

Specifications:

• installation width – 58 mm; Plastic windows KBE Engine (KBE Engine)
• maximum glass thickness – 34 (50) mm;
• number of cameras – frame 3 / sash 3 / impost 3;
• possibility of combination with a “wide frame”;
• frost resistance – up to -60°С;
• the maximum sash size of a PVC window KBE is 150 cm x 150 cm;
• maximum leaf size for balcony doors is 90 cm x 235 cm;

Technical characteristics of windows with Veka and KBE profiles

Installation parameters of “Veka” and “KBE” windows:

1. The largest installation width “KBE” is in the “Expert+” model, which is 127 mm.
2. Similar Veka windows have 70, 90 and 104 mm.
3. The widest package is 58 mm.
4. The 6-chamber Alphaline profile is similar to the 5-chamber Select KBE and is 50 mm. The remaining models have a double-glazed window with a thickness of 42-44 mm.
5. If there is a flange expander, then the KBE packages are 58 mm. A wide double-glazed window has high thermal efficiency and low noise levels.
6. In terms of heat transfer coefficient among 3-chamber windows, “Engine” and “Etalon” are similar to “Euroline”: “Engine” has a heat transfer coefficient of 0.62. "Standard" - 0.64.
7. For 5-chamber rooms, the heat transfer coefficient is: 0.74-0.85 (“Expert”, “Select”, “Select +”); 0.74-0.78 (Topline, Softline, Swingline).
8. The 6-chamber Alphaline has a coefficient of 0.94.

PVC profile KBE Expert

Thanks to the increased profile width and the five-chamber design of the frame and sash profiles, the KBE Expert window profile has improved thermal insulation properties that comply with the latest European energy saving standards. In addition, the wide profile allows for better insulation of the seam between the window and the wall when installing the window - and this is also an important factor in preserving heat in the room. Moreover, the possibility of combination with a wide frame solves the problem of “cold bridges” in cold types of walls. However, most of the window heat loss occurs not in the profile, but in the glass unit. The KBE Expert system allows you to install wider and warmer double-glazed windows with a thickness of up to 42 mm (using a rebate extender - up to 58 mm!) - with proper installation of such a window, you will not be afraid of any frost!

We save energy and money . In Europe, plastic window profiles with a width of 70 mm have already become the standard. This is not surprising - European practicality suggested that it is better to install a more expensive window once and then save significantly on heating than to “heat the street” from year to year. Moreover, the difference in price between “narrow” and “wide” profiles is not so great.

More silence . Residents of big cities value silence so much - it is important for us that the house has its own atmosphere, without the noise of passing cars. In addition to excellent thermal insulation and energy saving characteristics, thanks to the possibility of installing wider double-glazed windows and high sash closing density, windows made from the KBE Expert profile have increased sound insulation properties. Appreciate the comfort and tranquility that windows from the KBE Expert profile can give you.

More security . An additional advantage of the KBE Expert system is the ease of installation of anti-burglary fittings, which will make it difficult for strangers to enter the house through a window. For this purpose, KBE developers have provided a special technical solution in the profile (removing the 13 mm fitting groove). What’s especially nice is that the height of the wide profile “KBE Expert” is absolutely identical to the height of the narrow one, that is, windows from it will look just as light and airy, leaving designers room for imagination. Like other profiles of the KBE brand, “Expert” is produced using the latest greenline technology, according to which lead stabilizers traditionally used in the production of PVC profiles are replaced with environmentally friendly stabilizers based on calcium and zinc. In addition, the surface of the profile based on the greenline formulation has a pleasant matte gloss and resists negative climatic influences better than others. According to test results, KBE profiles can withstand temperatures from minus 60˚С to plus 75˚С. Tests have shown that greenline KBE profiles do not change their characteristics for more than 40 years of operation.

Advantages and disadvantages of KBE windows

Of course, these windows are most valued for their functionality and high technical characteristics. Thanks to the high quality of KBE window profiles, the products are guaranteed to last at least 40 years. What other advantages can these windows boast?

Advantages:

• High quality. The windows of this company meet all sanitary and hygienic standards and GOST. Numerous tests carried out by independent research centers and in the company’s own laboratory are one of the best confirmations.
• High thermal insulation performance. When creating window profiles, the company’s specialists focused on the manufacturability of the product. KBE windows guarantee minimal heat loss and protect from street noise.
• Environmental friendliness. Many people value this quality of KBE profiles. Windows are manufactured using special technology. This means that during the creation of the profile, lead was replaced with a special and safer compound of calcium and zinc.
• Variety of colors and designs.

Flaws:

• Not everyone can afford KBE windows. For high-quality and environmentally friendly windows you will have to pay a hefty sum.

PVC profile KBE Extra

The extensive geography of use of KBE plastic windows is achieved by the company’s principled approach to production to adapt products to climatic conditions as much as possible. Thanks to a powerful design base and research into the Russian climate and the peculiarities of building codes used in Soviet times, the company developed the KBE Extra system with a wide frame . Wide frame 127 mm. distinguishes this system from similar ones, increasing thermal insulation in brick buildings

Everyone is familiar with frost on windows or drops of water on slopes, but not everyone knows that such troubles greatly reduce the service life of windows. This indicates that the surface of the glass and slopes is below the dew point. This is especially true in brick houses with deep quarters, which significantly reduces the effectiveness of plastic windows for thermal insulation. The KBE Extra system was developed specifically for such cases and is maximally effective in the difficult climatic conditions of Russia, which is recognized as one of the most successful developments in the window industry.

Specialists of the German concern conducted a series of studies of thermal fields (isotherms) in facilities built in Russia, the results of which required the creation of the KBE Extra system. It turned out that in the period from 1960 to 1995, insulation technology was very different from Western ones, without effective insulation in the middle, the walls were built from a single-layer structure of brick or concrete, which greatly affects the location of thermal fields, increasing heat loss.

Plastic windows “KBE Extra” allow you to most effectively adapt Western technologies to the Russian climate. At the very beginning of the KBE company’s arrival on the Russian market, KBE specialists carried out all the work on studying and developing the product in close cooperation with Gosstroy. Thanks to this, the KBE Extra system acquired a profile width of up to 127 mm. taking into account the experience of Russian and Soviet builders, along with advanced Western technologies. The wide frame and five-chamber profile system made it possible to solve the problem of “cold bridges” and became the widest on the Russian market.

Design features of "KBE Extra":

The frame/frame has five chambers, while it has the ability to use standard sash systems. This design allows you to reduce heat loss in the direction perpendicular to the window slope.

A wide box of 127 mm allows you to reduce the gap between the frame and the slope to 5-10 mm, in cases where the quarters in brick houses are 133/137 mm. This design eliminates the problem of “cold bridges” in single-layer walls.

The width of the box and special pockets for installing platbands allow you to reliably protect the installation seam, eliminating blowing and provide an ideal finish to the internal slopes.

KBE Extra in the climatic zone of Russia:

According to Russian building codes, the main thermotechnical indicator is heat transfer resistance (Ro) “KBE Extra” has indicators of 0.71 m C/W. which fully satisfies the requirements for thermal insulation, even in the coldest points of our country, such as Irkutsk or Yakutsk, where in winter the temperature drops to -600C. Windows made from the KBE Extra profile will provide reliable protection for your home from frost. In addition, we note that KBE Extra plastic windows have all the advantages of plastic windows, such as excellent sound insulation, long aging, and ease of operation. It is also possible to use wood decoration and paint the KBE Extra profile in any color.
