Vacuum glass is made of two layers of glass, and a certain gap is retained in the middle to vacuum. The sound insulation effect of this vacuum glass theoretically does not transmit sound, and the sound cannot be transmitted under vacuum conditions. But actually the vacuum glass, because after the vacuum is finished, the two pieces of glass are almost attached together. The gap is very small, and some tiny support is needed between the glass. If there is no support, the glass will be crushed, then these supports will become the medium of sound transmission.
Vacuum glass is not suitable as a family broken bridge aluminum after practice. Soundproof window to use. It is suitable for use in laboratories with relatively large sound insulation requirements, recording studios and other places that do not need to design windows but need to fix large-area glass sound insulation walls.
The soundproof glass that is more suitable for family use is hollow glass. If you are not satisfied with the sound insulation effect of insulating glass. So what is better than insulating glass at present is that laminated glass.
