To what extent do PVC windows provide sound insulation?

The level of noise insulation provided by the metal-plastic windows depends on the characteristics of both the window profile and the insulated glazing unit: the tightness of the insulated glazing unit and the installed window as a whole, the multi-chamber feature of profile and the peculiarities of the sealers.

After a preliminary estimate of the noise level outside the window, a professional gauge will be able to select the desired glazing option. This can reduce the noise even from the busiest city main road to 40-45 dB (rustling of leaves in light wind).
