PVC profile filled with polystyrene What affects the width of the profile The correct choice of plastic windows should be based on a comprehensive analysis of their parameters. One of the main ones is the width of the profile, in a professional language - the mounting depth. For standard windows, it is 50 - 80 mm. If the width of the frame barely reaches 60 mm, then there are no more than three cameras in it, and with a depth of up to 70 mm there are four or even 5.

What fittings for plastic windows are better? Professionals advise choosing only products from well-known manufacturers. Cheap low-quality analogues can quickly become unusable.

Polyvinyl chloride itself for windows was not chosen by chance. This synthetic material is distinguished by: high weather resistance; low coefficient of thermal conductivity; low cost of production; environmental friendliness; excellent adhesion to most types of paints and varnishes; durability (at least 50 years of preservation of the main properties); weak conductivity of sound vibrations.

Decoration of PVC profiles Who produces high-quality profiles Basic profiles, from which window structures are assembled, are produced by several dozen factories in Europe, Russia and the CIS countries. Only one name of the manufacturing company can tell you how to choose plastic windows correctly. But as a finished product, a lot depends on the specific window assembler and its installation. Experience suggests that expensive quality profiles, as a rule, are used by responsible performers who produce excellent windows.

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.

How to determine the quality of the profile The first thing you need to pay attention to when buying windows is the appearance of the plastic. If the window is not laminated with decorative wood-like film, then the type of material will tell you a lot. High-quality polyvinyl chloride is a monolithic material, completely smooth, uniform in color. If spots are visible on it, or, worse, small or large grains, this is a fake, which is not worth buying in any case.

Frame profiles are slightly different. There are separate designs for bearing racks, sashes, crossbars). In any case, profiles from one manufacturer are used for one window, which are cut at the factory to the required length and assembled into one structure. The elements are connected by special welding or mechanical hardware.
