Aluminum foil laminated glass wool board phone number; 18630405298

The sound absorption properties of glass wool are not only related to thickness and bulk density, but also to factors such as covering material and structural structure. In construction applications, it is also necessary to take into account many aspects such as cost, aesthetics, fire protection, moisture resistance, dust, and aging resistance. Glass wool roll felt is a porous sound-absorbing material and has good sound absorption properties. The reason why centrifugal glass wool can absorb sound is not because of its rough surface, but because it has some small pores and holes that connect the inside and outside. When sound waves are incident on centrifugal glass wool, the sound waves can enter the material along the pores, causing the vibration of air molecules in the air space. Due to the viscous resistance of the air and the interaction between air molecules and pore walls, sound energy is converted into heat energy and is consumed.
