We recommend choosing plastic (PVC) windows in which the air chambers between the panes are filled with argon or krypton. This design will significantly save the cost of heating in winter and air conditioning in summer.

Reinforced profile PVC profile and negative temperatures One of the important characteristics of metal-plastic windows is frost resistance. This is the ability to maintain the integrity of all elements and heat-saving properties at a certain temperature. For the Russian climate, it is necessary to choose windows marked with the “M” index - frost-resistant. They retain all their characteristics down to -20 0C.

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".

Experience suggests that expensive quality profiles, as a rule, are used by responsible performers who produce excellent windows.

The more chambers, as well as the distance between their walls, the higher the noise performanceo- and thermal insulation. Two-chamber profiles are intended mainly for cold glazing, unsuitable for windows in heated rooms due to low thermal insulation.
