Acoustic Absorption Glass Fiber Board
Main components:
Glass wool is a kind of manmade inorganic fibers. It uses natural minerals such as quartz sand, dolomitic and limestone as the main raw materials.
Advantage:
1. Low bulk density
2. Low thermal conductivity
3. Excellent sound-absorbing performance
4. Corrosion resistance and waterproof.
5. Stable chemical properties
Acoustic Absorption Glass Fiber Board Application:
1. Sound absorption for entertanment places like TV station, recording studio and theatre.
2. Thermal insulation and cold insulation for construction, like roof..
