Metal-plastic windows are five-chamber (5). Five-chamber profile - description, features and types An 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, two main modifications are:
Rehau Delight;
Rehau Brilliant.

Common parameters

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

Another feature of these five-chamber Rehau is the increased safety against violation of the integrity of the structure and fitting systems.

Differences between Delight and Brilliant profile

The main difference between the 5 chamber Rehau is the design. The more expensive Brilliant has smooth lines and lends itself to a variety of styling in terms of color, texture, and toning.
And Delight, due to the roundness of the corners, allows you to significantly increase the flow of light into the room. As a decoration, special overlays are included. This profile also susceptible to lamination.

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

Defending its position in the highly competitive PVC window profile market, Rehau has updated its product line. Plastic Rehau windows are traditionally famous for the quality of the profile. One of the most interesting novelties of this popular European brand was no exception. Rehau Grazio windows have already captivated consumers with their beauty, elegance and ergonomics. New profile system constructively differs from other profiles of this company and deserves attention.

The difference between the Grazio profile and other Rehau profile systems

The novelty 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 Rehau Grazia frame and sash are “lowered” compared to their neighbors in the line.

In other words, profile sashes are narrower than conventional windows, due to which the glass occupies a larger area from 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 non-traditional geometry of the profiles, while its heat-shielding properties remain at a high level.

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

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

But the manufacturer still insists in its logic: the new profile outwardly and structurally resembles Delight in the number of chambers, installation 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 compares the main characteristics:

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

Specifications

Considering geometric and technical specifications Rehau Grazio profile, 70 mm mounting width (profile thickness) is far from its only advantage.

The main parameters of this system:

filling thickness - from 10 to 41 mm;
the number of internal chambers of the frame, sash, impost - 5;
2-loop seal along the porch;
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 an 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 in small window openings and in those rooms where it is especially important to provide a lot of light without heat loss during operation up to 60 years.

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

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

The white Grazio profile can be safely laminated with a special film that is resistant to UV and precipitation. It can also be painted with powder paint in any tone, and when choosing a filling with a thickness of 32 mm, put a curly rounded glazing bead on it. This opportunity expands the portfolio of interior solutions and makes the profile a godsend for everyone who prefers the extraordinary in the usual.

Reviews and average cost

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

Product type	Price per item	Price per m.2.
Single sash window	8 500 rub	6700
2 - folding	13 400 rub	7500
3 - folding	20 000 rub	7100
Balcony block	17 000 rub	6000

Grazio windows have replaced windows. The replacement turned out to be beautiful and practical. Unlike its 3-chamber predecessor, the new profile system is a 5-chamber system. glass area window frame, as well as sashes 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 the geometry well.

The original design of the frame and sash has beveled surfaces, characteristic only for this profile. 55 mm and 63 - a frame of this height favorably distinguishes the window of the Grazio system in the Rehau line. The second standard size is recommended in the official catalog of the manufacturer for the manufacture of structures of significant dimensions or for products that will be operated in conditions of increased wind load. This feature gives the translucent design a noble lightness.

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

One of the latest innovations is the five-chamber profile. Such systems have the highest performance and surpass their two- and three-chamber counterparts. What are their features? Do such structures have disadvantages? We will talk about this in our article.

Features of PVC windows with 5 chambers

Speaking of a 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 the penetration of cold into the room, which means that heat is stored much more efficiently.

The main difference between the five-chamber systems is that the metal reinforcing bar is removed from the window hinges, which prevents the occurrence of cold air flows 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. Center compartment added metal profile, which is an amplifying element. On both sides there are two more hollow sections. They do not allow heat to escape outside the room, and cold air flows to penetrate inside.

Design features

The high strength of plastic windows with 5 chambers allows the use of such systems in those places where required reliable protection from hacking. The profile is suitable for operation 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 ability 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 pieces;
thickness internal partitions- 3 mm;
the thickness of the double-glazed window itself is 42 mm;
plastic profile thickness - 70 mm;
block reinforcement system - 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 applies to dilapidated buildings.

How is a 5-chamber profile different 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 to maximize heat savings. Such designs are excellent for installation in regions where most year is dominated by low temperatures. In the central part of Russia, systems with three cameras are quite enough.

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

Specification Comparison

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 conservation coefficients. For units 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, advanced systems with an increased number of cameras are distinguished by 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 differ in strength. Five-chamber varieties are much more reliable, they can withstand significant physical impact. However, it should 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.

Varieties of systems with 5 cameras

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 views.

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

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

A five-chamber profile with a double-glazed window consists of three layers (4 mm). This design is able to provide a high degree of protection against cold and noise. Such systems are widely installed in residential premises.

Options with triple glazing consist of 4 layers. In this case, the thickness of the glass can be increased up to 6 mm. Such varieties are ideal for use in harsh climates.

additional characteristics

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

The ability to save energy systems acquire through the use of special glasses. UV protection is achieved by applying a special tint 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 more often made to order.

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

Five-chamber systems are superior in all respects to analogues with three sections, 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 what kind to buy?

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

For operation at medium temperatures (up to -25 degrees), three-chamber systems are quite suitable. If there is no need for improved noise isolation of the unit, standard options are preferable.

Summing up

When choosing window systems, cost always plays an important role. The price tag depends on the capabilities of the system and on 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 has varieties with anti-vandal coating and decorative processing. Non-standard parameter designs 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.
