Rehau Sib Design with thermoblock - the warmest windows

The plastic profile is the main structural element of window systems, so its characteristics become one of the selection criteria. It depends on them how long and effectively the window will last in the house. The German company Rehau has been producing profiles since 1954, so the description of its light-transmitting products, including Sib Design, can be given attention when searching for the optimal option.

Distinctive features of Sib Design

Most manufacturers of window systems offer 3-chamber profiles, but these products are not suitable for all weather conditions. The Sib Design profile production technology was designed specifically for Russia with its harsh winters. High thermal insulation properties are achieved by adding a thermal block to the structure. This is an air gap between the profile wall and the reinforcing frame.

Tests of the Rehau Sib profile system confirmed both temperature resistance and low thermal conductivity: the windows did not freeze or become covered with condensation. This feature will be appreciated even in the Far North, where it can be -45°C outside and +20°C indoors.

Window profiles of this brand have proven themselves in residential construction and when installed in public buildings. The versatility of Rehau Sib Design lies in its compatibility with other Rehau systems with an installation depth of 70 mm, as well as the ability to be built into window openings of any shape and size with various types of double-glazed windows.

Advantages of the Rehau Sib profile system

• Drainage is organized due to beveled seams.
• Modern aesthetics - 20-degree bevels add a special elegance to the design.
• Design possibilities. Profiles are not limited to the classic white color. When laminating, it is possible to either varnish or paste with a textured material to resemble wood, metal, etc.
• Additional profiles are securely fastened using mounting feet on the bottom of the main profile.
• Possibility of manufacturing windows and doors with both external and internal opening types.
• High levels of water and air tightness due to internal and external sealing with an overlap of 7 and 8 mm, respectively.

Minuses?

When ordering windows with a Rehau Sib Design 70 mm profile, the buyer often compares its cost with designs from other companies.

It is worth thinking about falsification if an installation company offers a window system under the Rehau brand at a price much lower than the market price.

Prices for Rehau products are slightly higher than the market average. There are several reasons for this:

1. Polyvinyl chloride (PVC) of the RAU-PVC brand (without cadmium additives) is characterized by high resistance to impacts, including at ultra-low temperatures, and increased fracture strength. It retains its properties under extreme atmospheric conditions, does not turn yellow, and does not change shape. Profiles made from such plastic do not emit harmful substances, can be recycled and have a long service life of 40 to 60 years.
2. Aesthetics of designs. The surface of the products has a pure white color with a muted gloss, but is resistant to external influences. The consumer will not see hand marks, scratches, or chips. This coating is perfect for additional design: lamination, painting, etc. And rubber seals, installed at an angle and necessarily closed along the contour, do not create a “frame” effect. In addition, manufacturers use elastic material that is resistant to temperature changes.
3. Easy to care for. Dirt and dust can be easily removed from the surface of windows with soapy water without the use of special cleaning agents. On the street side, the profile has bevels 15 mm wide, which makes maintenance even easier.
4. Reliability and attention to detail. Everything has been thought out in Rehau designs, from the U-shaped steel reinforcement to the protruding glazing bead, which prevents dirt from forming in corners and joints. If you buy these window profiles, you will receive a product that is strictly verified and produced according to technology.

Which is better Rehau Sib Design or Blitz?

Both Rehau window systems are made from high-quality materials, reinforced with a steel U-shaped contour, have increased strength, are burglary-resistant and are easy to clean. These profiles protect well from drafts, dust and extraneous sounds, reducing background noise by 40 dB to comfortable levels in residential areas. They are perfect for installation in the field of individual and public construction, fit into the interior and exterior of any design and are visually similar. Both Sib Design and Blitz apply a strict quality monitoring system.

But if the priority is warmth in the house, and the difference in seasonal temperatures reaches 60°C, then Rehau Sib 70 mm is preferable. The 3-chamber system in this profile will be wider and equipped with a thermal block, which acts as an additional air chamber. In addition, the thickness of the plastic walls will be increased to 3 mm as opposed to 2.7 mm in Blitz windows.

If the climate is moderate and there are no high requirements for thermal insulation, then the Blitz system will be a high-quality, but budget option for installation. The 60 mm profile and the possibility of installing a 2-chamber double-glazed window with a width of up to 32 mm allows you to achieve a heat transfer resistance coefficient of 0.64 (m²*°C)/W (class B1 according to GOST 23166-99). In this case, the consumer will save money without sacrificing functionality. You can read about other Rehau window models in our separate articles: Grazio, Intelio, Geneo, Euro, Delight.

Prices

Rehau Sib Design is considered the optimal example of the relationship between price and quality.

A standard double-leaf window measuring 1500x1500 mm will cost from 14 to 18 thousand rubles. But this is taking into account the complete turnkey package. This means that the final price depends not only on the costs of the plastic profile, but also fittings, double-glazed windows, trim, etc.

approximate price per meter from 4,200 rubles

The installation company determines the cost of the turnkey window, including the work of its installers and measurers. She also often offers a system of discounts. If you select a window design for the entire apartment, then Rehau plastic windows will be inexpensive for the buyer.
