Metal-plastic windows are five-chamber (5). Five-chamber profile - description, features and types Example of the cost of Rehau Grazio in a Moscow company

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 profile Rehau is characterized by increased strength, since the walls of the chambers 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 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.

Defending its position in the highly competitive market of PVC window profiles, Rehau has updated its product line. Plastic Rehau windows 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. New profile system It 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 conventional windows, due to which the glass occupies a larger area of the window, letting in more light.

This nuance gives the finished window an 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 windows Rehau (Grazio system) are recommended for installation in climatic zones with average temperatures in winter 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 specifications make it possible to produce structures with advantageously different 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 subtle beauty of the new profile system, its rounded corners, beveled surfaces, snow-white glossy color provide ample opportunities 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 painted with powder paint 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 product on the window market is perceived with caution by consumers. People, by inertia, trust resonant marks and brands. Rehau plastic windows are traditionally popular in the market, but customers window companies got used 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.

We allowed PVC window structures to become the most popular in both the domestic and foreign markets. Manufacturers are constantly improving their products, improving their sound and heat insulation capabilities.

One of the latest innovations is a five-chamber profile. Such systems have the highest characteristics and are superior to their two- and three-chamber counterparts. What are their features? Do such designs have any disadvantages? We will talk about this in our article.

Features of PVC windows with 5 chambers

Speaking about the five-chamber profile, you need to clearly understand what a camera is. In this case we are talking about empty sections located in the window structure. The air inside each chamber prevents cold from penetrating into the room, which means heat is retained much more efficiently.

The main difference between five-chamber systems is that the metal reinforcing strip is removed from the window hinges, which prevents the occurrence of cold air currents in the most vulnerable places of the structure.

If we look at the five-chamber profile in section, we will see that it consists of 5 sections. The central compartment has been expanded metal profile, which is a reinforcing element. There are two more hollow sections on both sides. They do not allow heat to escape outside the room, and flows of cold air to penetrate inside.

Design features

The high strength of plastic windows with 5 chambers allows the use of such systems in places where it is required reliable protection from burglary. The profile is suitable for use in the temperature range from -60 to +60 degrees. At the same time, manufacturers guarantee an impeccable 40-year service life of their products.

Five-chamber profile plastic window- the opportunity to make your home quiet and warm, but before choosing such systems, pay attention to their parameters. Standard options are characterized by the following indicators:

number of air chambers - 5 pcs.;
thickness internal partitions- 3 mm;
the thickness of the glass unit itself is 42 mm;
plastic profile thickness - 70 mm;
The block reinforcement system is of a closed type.

These values are important in cases where you need to accurately calculate the load that the PVC system will exert on the opening. In most cases this concerns dilapidated buildings.

How does a 5-chamber profile differ from a 3-chamber profile?

Choosing between three-chamber and five-chamber PVC profile, it should be understood that the main purpose of windows of the second type is maximum heat conservation. Such designs are ideal for installation in regions where most Low temperatures prevail throughout the year. In the central part of Russia, systems with three cameras are quite sufficient.

You also need to take into account the increased parameters of the unit with 5 cameras. If a system with a triple profile has a width of 60 mm, then the option we are considering is 10 mm wider. If you decide to give preference to this particular design, pay attention to the parameters of your window opening. Sometimes installing wide systems is simply not possible.

Comparison of technical characteristics

When choosing a three-chamber or five-chamber profile, pay attention to the technical characteristics of both systems. Their main difference lies in the difference in heat retention coefficients. For blocks with three chambers, this figure varies from 0.6 to 0.65 m 2 /kW, and for similar systems with 5 chambers - from 0.75 to 0.8 m 2 /kW.

In addition, improved systems with an increased number of cameras provide reliable protection against the penetration of extraneous sounds into the room. For blocks with a three-chamber profile, this figure is 30% lower.

PVC systems also differ in strength. Five-chamber varieties are much more reliable; they can withstand significant physical impacts. However, it must be borne in mind that along with high strength, such structures have acquired additional weight. It is not recommended to install them in frame buildings.

Types of 5-camera systems

In PVC structures with a five-chamber profile, several types of double-glazed windows are used. Namely:

single-chamber varieties;
two-chamber options;
three-chamber types.

The chosen glazing option directly affects the heat and sound insulation capabilities of the system. The total weight of the block also changes.

Thus, the single-chamber version consists of two glasses 4 mm thick, between which there is a gas or air layer. The total width of this variety is 24 mm. This is the most a budget option with low functional indicators.

The five-chamber profile with a two-chamber double-glazed window consists of three layers (4 mm). This design can provide a high degree of protection from cold and noise. Such systems are widely installed in residential premises.

Options with three-chamber double-glazed windows consist of 4 layers. In this case, the thickness of the glass can be increased to 6 mm. Such varieties are ideal for use in harsh climates.

additional characteristics

The five-chamber window profile can have Additional features. This includes a high degree of noise insulation, energy saving, protection against burglary and ultraviolet rays.

The systems acquire the ability to save energy through the use of special glasses. UV protection is achieved by applying a special tinting film to the glass, and resistance to mechanical stress is achieved through an anti-vandal coating.

There are varieties with curved and decorated glass, but they are rarely found on sale and are often made to order.

Which profile to choose: single-chamber or three-chamber?

Five-chamber systems are superior to analogues with three sections in all respects, but their installation is not always advisable. Firstly, such structures are quite heavy, and secondly, their price tag is 18-20% higher than the cost standard products with three cameras. So which variety should you buy?

When choosing a window unit, rely on the natural conditions of your area and the specifics environment. If the climate is close to harsh, and there is a noisy highway outside the window, then options with 5 cameras are ideal for you.

Three-chamber systems are quite suitable for operation at average temperatures (up to -25 degrees). If there is no need for improved sound insulation of the block, standard options are preferable.

Let's sum it up

When choosing window systems, cost always plays a big role. The price tag depends on the capabilities of the system and the manufacturer. For example, a five-chamber Rehau profile with basic characteristics will have a price tag of 6,000 rubles for a standard double-leaf window. At the same time, products with a triple profile can be purchased for 3000-4500 rubles.

If you want to install a unit with maximum energy efficiency and UV protection, expect to pay 20% more. The maximum price tag is for varieties with anti-vandal coating and decorative processing. Designs with non-standard parameters can also cost an order of magnitude more.

You can also purchase cheaper options from Chinese manufacturers, but the quality and durability of such products remain in question.
