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.

If a company offers a mega-durable functional window from a thick branded profile frombloody "ridiculous" price (and with 100% prepayment of work) - at least you should be wary.

Sooner or later, but a sealant working in a stressful mode, which can withstand both mechanical and thermal and chemical influences, the material wears out. It is not difficult to make a replacement even on your own, if you choose a suitable sealant from the entire range of products offered by manufacturers.

PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.

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.

What does a plastic window consist of? Profile is the main element of a window block. Its purpose is to combine other components into a whole structure.

What you need to know when choosing pvc windows When you want to buy plastic windows, you get the feeling that they are all the same. White in color, with similar handles, glasses and seals - you just need to say the dimensions and choose those that are cheaper. But in this case there are many nuances that it is desirable to know when choosing a window.

Decorated and white windows differ in a number of mechanical indicators. The laminated frame, especially in dark colors, is more heated by the sun. This necessitates the mandatory reinforcement of the profile, regardless of the size of the structure.

Why plastic windows are better Hermetic design prevents heat loss, which is especially important in houses with insufficient heating system capacity and apartments in which heating appliances are equipped with meters and temperature controllers.
