2.vapor impermeability
3.no water absorption
4.incombustibility
5.sound absorption

 Application

 

1 . used in the designing of sound effect in halls and auditoriums to control the interior reverberation time .for instance ,it can be used as a sound effect solution in music halls, theaters, movie theaters,auditoriums,conference hall and dancing hall as well as the studios for broadcasting ,TV and movie productions.

 

2.Since the sound absorbing cellular glass has sound waterproofing and aging resistance,it is especially suitable in the humid environments and open air with windy and rainy weather.For instance,it can be used for noise reduction or sound barriers on road or in swimming pools ,subways,underground engineering and chilling towers.

 

3.Used in waiting rooms  at airports, bus stations,ports or shopping malls as well as exhibition halls, the flat roofing and wall made with sound absorbing cellular glass can reduce the reverberation and thus increase the clearness of the broadcasting.

                

4.The sound absorbing cellular glass can be used as silencers too. Compared with fiber sound absorbing materials,the cellular glass does't emit fiber dust into the air ,thus suitable for the ventilation and air condition which requires clean environment .
