Comparison table of characteristics

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

Today, Rehau window systems are a combination of reliability, durability, practicality, and energy efficiency. Profiles used in Ukraine are: 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, consider their structure.

Choosing basic system from Rehau, the Euro Design 60 profile should be noted.

Rehau Euro 60 system (three-chamber profile):

1. Profile width - 60 mm;

2. Thickness of a double-glazed window - 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 R w, P = 41 dB;

Rehau Euro 60 PVC profile windows are optimal solution for all types window systems for all specifications. The profile has three air chambers, two sealing circuits.

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

What metal-plastic windows to choose from a 3- or 5-chamber Rehau profile?

Due to the composition of the plastic, windows from the Rehau Euro Design 60 and Euro Design 70 profiles have an excellent smooth surface, dirt is not absorbed, windows special care do not require and retain whiteness.

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

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

PVC windows of 5-chamber and double-glazed windows with energy saving offered by Harvest Industriales specialists, if it is necessary to glaze private house or a cottage with autonomous heating.

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 highest performance and outperform 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 strip is removed from the window hinges, which prevents the occurrence of cold air currents in the most vulnerabilities designs.

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 cameras allows the use of such systems in places where reliable protection against burglary is required. 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.

The five-chamber profile of a plastic window is an 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 air chambers- 5 pieces.;
• thickness internal partitions- 3 mm;
• the thickness of the double-glazed window itself is 42 mm;
• thickness plastic profile- 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 years prevail 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 specifications 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 more cameras are different reliable protection from 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. V frame buildings it is not recommended to install them.

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. Also changes total weight block.

So, a 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 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 designs are quite heavy, and secondly, their price tag is 18-20% higher than the cost of standard products with three cameras. So what kind to buy?

When choosing a window block, rely on natural conditions your locality and 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 sound insulation of the unit, standard options preferred.

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.
