How to choose high -quality plastic windows.
Modern plastic windows have a large number of advantages compared to windows with wooden frames. But you should figure out how to choose a high -quality plastic window?

To choose a high-quality plastic window, you should carefully study the manufacturers that produce metal-plastic windows. You also need to make sure that the certificate of conformity, the certificate of din ven is 9001, license for the production of building structures and the most important thing, this is a license for installation (installation) of structures.

You should also ask the quality of the reinforcing profile: the steel galvanized is good, and the usual metal is unstable to corrosion and has a low strength threshold. The inside of the profile is a hollow and consists of a large number of air chambers: it is better when there are many, because then the window will be warmer.
Next, you need to pay attention to the central part of the window – double -glazed window. It must have a thickness of 32 mm, the glass of the M1 brand, polished, have at least two inter -stacked chambers.
When choosing a high -quality plastic window, you should pay attention to windows with energy -saving glass. Such glass has two coating labeling, it is L – glass and K – glass. Air chamber is filled with transparent gas.
