It is worth noting that any window, even in an ordinary wooden frame, protects us from external noise from the street. Just the amount of penetrating noise depends on the density of the adjustment of the window to the frame. As you know, plastic windows have a special design, thanks to which all their details are close to each other.
From the school physics course, we all remember that sound is fluctuations in physical bodies, and it is transmitted through air fluctuations, solid objects or water. Noise penetrates due to air fluctuations between the glasses and the rubber seal of the frame itself. We see this with examples of ordinary wooden windows. They, thanks to gaps in frames, pass up to 70% of external noise.
However, plastic windows are made using reliable locking accessories, and a sealed rubber seal is laid throughout the edge of the double -glazed windows. Thus, if the window is mounted in compliance with all technologies, external noise through the wings can penetrate the room only through sound fluctuations in the PVC or air profile inside. But the percentage of penetrating noise is much lower – up to 30%.
When you choose plastic windows for your home, ask the consultant how much the double -glazed window has air chambers. In the cold season, a window with more air chambers will protect you from cold. In general, it is necessary that the window has from three chambers and higher in the profile and in the wings, but the more there are, the thermal insulation in the room, and noise insulation will be more reliable. In the warm season, such a design will also serve as a thermostat for your apartment and will not allow air overheating inside.
The glasses themselves can also transmit sound vibrations. But since they are firmly fixed in the double -glazed window with a rubber gasket, the oscillations are possible minimal – they are immediately neutralized. That is, the complete tightness of the plastic window serves as a protection against noise.
In the event that you live opposite the highway or near the railway or tram tracks, the problem of external noise will eliminate the installation of a glass packet with the help of specialists of the installer. You will be recommended to order PVC windows with thick glasses of at least 5 mm, with a rate of 4 mm. Or you can choose “triple” plastic windows – this is a glass consisting of 3 or more tightly glued together glasses. Only they have a large weight compared to standard glass packet. This situation must certainly take into account and choose special PVC profiles for such heavy glasses.
