Plastic windows reduce the penetration of the noise of the street into the living room, but it will be completely impossible to get rid of it, since low -frequency noises will still be audible, although their intensity will decrease significantly. The tightness of the plastic windows is that they exclude all kinds of drafts, but they are not sealed by themselves. The same misconception includes the opinion that between the glasses of the double -glazed window is a vacuum. If this were so, then atmospheric pressure would break these glasses. Although part of the truth is in this — so that the glass in the double -glazed window is pressed, reduced pressure is created, but this is not a vacuum in its physical sense.
