What should we do if there is too much noise when we live near the road or near the construction site? Today KXG(Kunxing Building Glass Factory) will introduce the sound insulation capabilities of different types of glass doors and windows.


The ranking of the sound insulation ability of common double-glazed doors and windows on the market: Vacuum glass>Inert gas filled insulated glass>Ordinary insulated glass

Vacuum glass and insulating glass are both double-layered glass, and vacuum glass is to vacuum the middle layer of two pieces of glass. Sound transmission requires a medium. The middle layer of vacuum glass does not have any medium for sound transmission, which is equivalent to cutting off the path of sound transmission. So vacuum glass is the best sound insulation glass.


Some insulated glass will be filled with inert gas in the middle layer, such as argon, krypton, xenon. The sound transmission ability in inert gas is weak, so filling the inert gas in the insulated glass can greatly reduce the transmission of noise.


There is air in the middle layer of ordinary insulated glass, and the medium for sound transmission is still there, but the consumption of double-layer glass can also reduce a certain amount of noise.

The sound insulation of windows is not only related to glass, but also related to the metal frame of the window, sound insulation strips and other factors. If you want to achieve a good sound insulation effect, you need to pay attention to the closeness of the window frame and the window sash during installation, and use high-quality sound insulation strips, seals and other issues.
