REHAU is the patriarch of plastic windows. Four- and five-chamber double-glazed windows Description of a multi-chamber double-glazed window

Taking a stand in a highly competitive market PVC window profiles, Rehau company has updated its product line. Rehau plastic windows are traditionally famous for their profile quality. One of the most interesting new products from this popular European brand was no exception. Rehau Grazio windows have already captivated consumers with their beauty, elegance and ergonomics. The new profile system is structurally different from other profiles of this company and deserves attention.

The difference between the Gratio profile and other Rehau profile systems

The new product in the Rehau line, Rehau Grazio, stands out not only for its graceful name. The profile attracts with its special sophisticated appearance. With an installation depth of 70 mm and 5 internal chambers, the frame and sash of the Rehau Gracia are “lowered” compared to their neighbors in the line.

In other words, the profile sashes are narrower compared to ordinary windows, due to this, the glass occupies a larger area from the window, letting in more light.

This nuance gives ready window attractive appearance. The translucent structure has a larger light opening due to the unconventional geometry of the profiles, while its heat-shielding properties remain at a high level.

The test report, which is mandatory for any manufacturer of PVC profiles, indicates that energy-saving Rehau windows (Grazio system) are recommended for installation in climatic zones with an average temperature of winter period up to -40°C. In order for such energy-saving windows to perform their heat-protective role to the maximum in harsh climates, the profile must be supplemented with a 2-chamber thermal unit or a double-glazed window with a thickness of at least 40 mm with multifunctional low-emissivity glass.

You can get acquainted with the new profile and its description by the official representative of Rehau in Russia on the Russian-language portal of the same name or from processors - manufacturers of translucent structures.

Comparison of Rehau Grazio and Delight

By price system by 10-15% also more attractive than the 5-chamber These two lines are often compared with each other, considering Gratio visually more similar to Delight.

But the manufacturer still insists in its logic: the new profile is externally and structurally reminiscent of Delight in the number of chambers, mounting depth and “lowered” (narrower) sash, but it is still closer to the one taken out of circulation. True, it protects against heat loss better (its heat transfer resistance coefficient is higher) and has a higher sound insulation class.

The table below provides a comparison of the main characteristics:

*104 mm is better than 109 mm, since the area of the frame and sash (the opaque part of the window) is smaller.

Specifications

If we consider the geometric and technical specifications Rehau Grazio profile, 70 mm installation width (profile thickness) is far from its only advantage.

The main parameters of this system:

filling thickness - from 10 to 41 mm;
number of internal chambers of the frame, sash, impost - 5;
2-circuit seal along the rebate;
sound insulation class according to GOST 23166-99 - B;
air tightness class according to GOST 23166-99 - A;
water resistance class according to GOST 23166-99 - A;
heat transfer resistance coefficient - 0.85 m2oC/W;
thickness of the outer outer wall - 2.8 mm;
the height of the sash with overlap on the frame is 104 mm.

Such technical characteristics make it possible to produce structures with advantageous light transmission. This makes this system indispensable for the manufacture of products for small window openings and in those rooms where it is especially important to provide a lot of light without heat loss during operation for up to 60 years.

Technological innovations have also affected the sealing of the vestibule, which is made of cellular rubber and has excellent sealing properties.

The refined beauty of the new profile system, its rounded corners, beveled surfaces, and snow-white glossy color provide ample opportunities for interior designers and architects designing the filling of window openings.
Despite the lower sash and frame than other systems, Grazio can be used to produce traditional rectangular windows and doors, as well as arched or trapezoidal products.

The white Gratio profile can be safely laminated with a special film that is resistant to ultraviolet radiation and precipitation. It can also be powder-painted in any tone, and if you choose a 32 mm thick filling, a shaped rounded glazing bead can be placed on it. This opportunity expands the portfolio of interior solutions and makes the profile a godsend for everyone who prefers the extraordinary in the familiar.

Reviews and average cost

Any new item on window market perceived by consumers with caution. People, by inertia, trust resonant marks and brands. Rehau plastic windows are traditionally popular in the market, but clients of window companies are accustomed to the old names - Sib Design, Delight. Despite this trend, the innovative Rehau Grazio 70 mm in depth and number of internal chambers already conquered the market at the start of sales.

Product type	Price per product	Price per m2.
Single sash window	RUB 8,500	6700
2 - casement	RUB 13,400	7500
3 - casement	20,000 rub.	7100
Balcony block	17,000 rub.	6000

Gratio windows replaced windows. The replacement turned out to be beautiful and practical. Unlike its 3-chamber predecessor, the new profile system is 5-chamber. Glass area window frame, like the sash, due to the lowered profile, it turns out to be enlarged, which means that such a window lets in more light. Full reinforcement with a lower profile gives the products strength and holds their geometry well.

The original design of the frame and sash has chamfered surfaces characteristic only of this profile. 55 mm and 63 - a frame of this height makes the window of the Gratio system stand out in the Rehau line. The second standard size is recommended in the manufacturer’s official catalog for the manufacture of structures of significant dimensions or for products that will be used under conditions of increased wind load. This feature gives the translucent structure a noble lightness.

Premium German brand on the Russian market since 1995. With us you get real German quality from a company with a 48-year history around the world.

ALL profile systems of the highest class “A”
ALL are made frost-resistant and marked with the letter “M”
ALL have maximum 4-sided steel reinforcement
Uniform quality standard regardless of country of production

The more air chambers, the less air exchange and, accordingly, the higher the thermal insulation.

The wider the profile and the greater the installation depth, the higher the thermal insulation.

Profiles ONLY of the highest class “A”

According to the thickness of the internal walls, ALL of our profiles are of the highest class “A” - the thickness of their front wall is at least 3 mm.

class “A”: front wall not less than 3.0 mm
class “B”: front wall not less than 2.5 mm
class “C”: wall thickness is not standardized

Please note that 80-90% Russian market these are classes “B” and “C” and only 10-20% of class “A” profiles. At the same time, our assortment includes ONLY class “A” profiles.

We fundamentally DO NOT use profile systems of classes “B” and “C” (with a front wall width of less than 3.0 mm).

ONLY frost-resistant profiles

According to GOST 30673-99 “PVC profiles for window and door units” for resistance to climatic influences, ALL of our profiles are “frost-resistant” - for areas with an AVERAGE monthly air temperature in January BELOW minus 20°C.

GOST standards for different classes:

normal version “N”: the average temperature in January is minus 20°C and above
frost-resistant version “M”: the average temperature in January is lower than minus 20°C

Our assortment includes ONLY frost-resistant profile systems marked with the letter “M”.

Heat transfer resistance (thermal thermal resistance) is the main thermal insulation coefficient. Determined by the ratio of the temperature difference between outside and inside the room to heat flow passing through the window. The higher this number, the better the insulation performance.

Evolutionary double-glazed windows SmartGlass 2.0

Our multifunctional double-glazed windows work for you both in winter and summer. In winter, the spraying of silver particles retains up to 90% of the thermal energy of heating devices, and in the summer, a double-glazed window reflects 25% more solar heat than conventional plastic windows.

42% more HEAT in winter (energy saving properties)
25% less HEAT in summer (sun protection properties)

All our double-glazed windows contain special energy-efficient glass. We DO NOT use regular glass even in the most basic configurations.

AirDrive I, II and III climate control systems

Optimal ventilation mechanisms are built into the windows - the sashes open slightly by 1-5 mm, depending on the selected mode. These are NOT external devices (combs or valves), but BUILT-IN ventilation fittings.

Three options:

AirDrive I: slot ventilation (1 mode)
AirDrive II: discrete multi-stage ventilation (3 modes)
AirDrive III: discrete multi-stage ventilation (5 modes)

We try not to place combs based on their appearance (only at your request). In principle, we do not use valves due to the fact that they violate the integrity of the window, reduce its tightness and strength (since the profile and its reinforcement are drilled through).

Today, Rehau window systems are a combination of reliability, durability, practicality, and energy efficiency. In Ukraine, the following profiles are used: Euro Design 60 (3-chamber), Euro Design 70 (5-chamber), Brillant Design (5-chamber), Ecosol Design 70 (5-chamber) and Geneo (6-chamber).

To determine the differences between Euro Design 60 and Euro Design 70, let's look at their structure.

When choosing a basic system from Rehau, you should note the Euro Design 60 profile.

Rehau Euro 60 system (three-chamber profile):

1. Profile width - 60 mm;

2. Double-glazed window thickness - up to 32 mm;

3. Air chambers - 3;

4. Thermal insulation: U f = 1.6 W/m²K / R f **= 0.62 m²K/W;

5. Sound insulation: up to Rw,P = 41 dB;

Windows from PVC profile Rehau Euro 60 is the optimal solution for all types window systems on all technical specifications. The profile has three air chambers and two sealing circuits. Ideal for any design thanks to its external contours (ideal smooth surface). Near a 3-chamber plastic window high level energy saving and noise reduction.

Rehau Euro 70 system (five-chamber profile):

1. Profile width - 70 mm;

2. Double-glazed window thickness - up to 40 mm;

3. Air chambers - 5;

4. Thermal insulation: U f = 1.3 W/m²K / R f **= 0.77 m²K/W;

5. Sound insulation: up to R w, P = 43 dB;

6. Two sealing circuits ensure air and water tightness;

7. Easy to use and maintain due to the fact that the profile surface is smooth;

8. Environmentally friendly profile, recognized as safe for human health (recommended for installation in children's and medical institutions).

Excellent heat and sound insulation qualities, excellent profile appearance, smooth surface, optimal price. It is these characteristics of this system that are the result of the fact that 5-chamber PVC windows are considered best choice, taking into account that the cost of a profile in Ukraine is one of the most important indicators for the consumer.

Which metal-plastic windows to choose, from the 3- or 5-chamber Rehau profile?

Thanks to the plastic composition, windows made from Rehau Euro Design 60 and Euro Design 70 profiles have an excellent smooth surface, dirt is not absorbed, windows do not require special care and remain white.

When choosing a 3-chamber (Rehau Euro Design 60) or 5-chamber (Rehau Euro Design 70) profile system, you need to consider which object needs to be glazed.

PVC windows 3-chamber and single-chamber double-glazed windows with energy saving It is enough to install if the heating is centralized.

5-chamber PVC windows and double-glazed windows with energy saving specialists from the Harvest Industriales company offer, if glazing is necessary a private house or a cottage with autonomous heating.

Rehau plastic windows are designed specifically for our country, with its temperature changes. Double-glazed windows of this brand have good sound insulation, ventilation, burglary protection, stylish design, and, of course, reasonable prices.

The line of rehau profile models includes 3, 4 and 5 chamber products. Among the latter there are two main modifications:
Rehau Delight;
Rehau Brilliant.

Common parameters

5 chamber Rehau profile It is characterized by increased strength, since the chamber walls are reinforced. The depth of the chamber is 70 mm. The heat saving and sound insulation indicators are the highest possible thanks to the double-circuit seal. With them, not only will rain and wind not disturb the residents, but the possibility of dust ingress is also eliminated.

Another feature of these five-chamber Rehau is increased safety against damage to the integrity of the structure and fittings systems.

Differences between Delight and Brilliant profiles

The main difference between 5 chamber Rehau is the design. The more expensive Brilliant has smooth lines and can be stylized in a variety of colors, textures, and toning.
And Delight, thanks to the roundness of the corners, can significantly increase the flow of light into the room. For decoration, the kit includes special overlays. This profile is also susceptible to lamination.

But the main thing for choosing a profile is not technical or stylistic parameters, but the fact that 5-chamber Rehau products are the most durable and durable among all window systems.
