When choosing a PVC double -glazed window, note that polished glasses should be installed not lower than M1 brand. If you will be offered brands M2, M3, M4, then you do not need such plastic windows. The manufacturing company can be asked to provide a documentation that confirms the glass brand.
According to the requirements of regulatory documentation, as a rule, two -chamber double -glazed windows, or single -chamber with energy -saving glass, are used.
Plastic windows have the main parameter – the thickness of the double -glazed window reaching 32 mm (especially if the window goes outside).
Once the time comes when the question arises in my head, how to choose plastic windows correctly so that the funds spent on them are invested correctly.
For the correct investment of your money, the plastic windows that you purchase must be very high quality, and they also must meet all aesthetic environmental and modern requirements.
Now such windows are made from PVC (polyvinyl chloride). This is a traditional and time -tested material for the production of metal -plastic windows. Goods that are made of PVC will serve for at least three decades, while they will retain all their best qualities throughout the entire operational period.
PVC is a thermal insulation material that does not accumulate moisture, the fungus does not develop in it. Also, the main advantages of such windows include resistance to ignitability, and in the case of a fire, they are characterized.
As a rule, in the production of PVC windows, special additives are used, which ensure the stability of windows to various climatic factors (snow, hail, rain).
