Soundproof glass

The soundproof window is composed of double or triple layers of different thickness glass and window frame. There are two kinds of processed methods for the glass,one is laminated glass which the glasses are bonded by high temperature and high pressure using PVB, especially using acoustic PVB. The other is insulating glass which glasses are combined by the aluminum alloy frame filled with a desiccant (molecular sieve) and the edge with a sealant (butyl rubber, polysulfide rubber, structural adhesive).

1. The thickness of the hollow layer of the sound-insulating glass: generally about 6 mm, 9 mm or 12 mm, too small hollow layer, the basic meaning is not big.

2. The more the number of glass layers, does not mean that the sound insulation effect is better: Many consumers think that if two layers of glass can not be sound-insulated, three layers of glass are installed. In fact, this method is extremely wrong. The more layers used by glass, the more it will cause. The smaller the air layer between the glass, the worse the sound insulation effect. The sound insulation effect of the three-layer glass may not be as good as that of the double-layer glass, especially for the low-frequency noise generated by automobiles, trains, airplanes, etc.

3.Install a layer of the same hollow glass window, the sound will be half the sound of the present: In fact, this is a common sense misunderstanding, the more the sound wants to descend below, the more difficult it will be! The physical properties of the insulating limit of insulating glass are certain. Even if a few layers of insulating glass are added, it is difficult to reduce the sound more, because if it breaks through the noise limit of the insulating glass, it will be easy to use insulating glass. Breakthrough, this is why many of the noise-contaminated glass is difficult to play a good soundproofing effect.

4.Vacuum glass sound insulation effect is not necessarily good: some consumers believe that the vacuum sound insulation effect is excellent, this understanding is also a misunderstanding, although the vacuum can prevent the sound, but in order to ensure the vacuum layer, the vacuum glass is added to the naked eye between the glass The solid support that is not visible forms a solid sound, and the sound insulation effect is not as good as imagined. It is understood that the cost of vacuum glass is very high, the price per square meter can reach 1200-1400 yuan, the market is really a lot of situation.
