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.
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.
The most common window profile width levels in Russia are 60 (from 58 to 62 mm) and 70 (from 70 to 76 mm). For most regions of our country, the second option is preferable.
Metal strips are hidden inside the profile and act as a strength enhancer. Sometimes windows of a similar design are called metal-plastic, which is more true than just plastic or PVC. The function of metal inserts is very important to ignore.

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.
Multifunctional double-glazed windows have good light transmission. Due to the thickness of the profile, they are resistant to mechanical damage.
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.
