Application
After compunding corresponding veneer materials, glass wool felt and glass wool board products can be used as packaging material of the thermal insulation layer of duct outer wall, or mounted on inner wall of the duct as sound elimination liner to control heat transfer effectively through duct wall and reduce the loss of heat during ventilation and gree eliminate sound transfer in duct.
