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": average temperature in January - minus 20°С 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, spraying silver particles retains up to 90% of thermal energy heating devices, and in summer the 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).

Allowed window structures made of PVC 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 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 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. The central compartment is complemented by a 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 similar systems in places where reliable protection against burglary is required. 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 of internal partitions - 3 mm;
• the thickness of the glass unit itself is 42 mm;
• thickness plastic profile- 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?

When choosing between a three-chamber and a five-chamber PVC profile, you should understand that the main purpose of windows of the second type is maximum heat conservation. Such designs are excellent for installation in regions where the weather prevails most of the year. low temperatures. 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 are distinguished by reliable protection against the penetration of extraneous sounds into the room. Blocks with 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 influences. However, it must be taken into account that, along with high strength, such structures have acquired extra weight. IN frame buildings It is not recommended to install them.

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. Also changes total weight block.

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 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 high degree 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 Features

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. Ultraviolet 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 designs are quite heavy, and secondly, their price tag is 18-20% higher than the cost of standard products with three chambers. 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 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.

Today window Rehau systems is 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. Glass 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 of window systems across 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 surface of the profile 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 appearance profile, 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 composition of the plastic, windows made from Rehau Euro Design 60 and Euro Design 70 profiles have excellent smooth surface, dirt is not absorbed, windows special care do not require 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 private house or a cottage with autonomous heating.
