For an apartment window in a big city, it makes sense to consider at least a three-chamber profile. For rooms located on high floors, apartments with a poorly functioning heating system, and rooms overlooking highways and multi-lane avenues, five- and six-chamber designs are suitable.

The seal should be: as flexible as possible; durable; do not lose their properties at low and high temperatures (-20 ... + 55 0С); do not emit odors and toxic fumes; do not change colors over time.

Three-chamber double-glazed windows are rarely used in PVC windows, as they are too thick and heavy. Modern technologies make it possible to achieve comparable indicators of thermal and noise protection in simpler ways.

The seal should be: as flexible as possible; durable; do not lose their properties at low and high temperatures (-20 ... + 55 0С); do not emit odors and toxic fumes; do not change colors over time.

The reinforcing element of the window is a U-shaped or square profile, which is inserted into the largest chamber located in the center. The thickness of the sheet metal from which the profile is formed is in the range of 1.5 - 2 mm. It is made of galvanized steel and is highly resistant to corrosion. An amplifier is installed in almost all structures, although according to the standards, with a frame length of less than 0.8 m, it can not be used.

On the market you can also find windows with a trapezoidal section of the front part of the frame, the so-called "Dutch" or "Danish". Their installation depth exceeds 100 mm and often they do not require the installation of external slopes, completely blocking the opening. Such windows are more efficient than conventional rectangular ones, but they are also more expensive.

Window profiles are produced according to EN 12608 SR (Europe) and GOST 30673-99 (Russia). According to the main indicators, they are almost identical. The main parameters are the thickness of the walls of the outer contour and internal partitions. According to these indicators, the profile is divided into three types - "A", "B" and "C".

Availability of certificates For each component of the window (profile, double-glazed window, fittings, components) there is a separate GOST. Manufacturers of materials and products for completing windows must obtain certificates of conformity for their products.

Order a free call Selecting the type of sash opening When choosing plastic windows, you should decide on the type of sashes. They determine the functionality of the design and comfort during its operation. The type of sashes must be selected depending on the size of the structure, how many windows are in the room and whether there is a need for regular ventilation.

Wooden frames, as an alternative, also cannot be called an example of environmental friendliness. In their production, glues, impregnations, varnishes and paints are used, often with a dubious composition.
