Aluminum foil facing glass wool felt

Aluminum foil facing glass wool felt 1 CE certificate 2 Grade A1 fireproof 3 moisture-proof 4 heat insulation

   Adopting all-directional paste form, which is firmer.    Unique technology; rebound degree after compressive packing is up to 99.2%.   Soft and long glass fibers can maximally lessen flying catkins in the construction.   Sound absorption and noise reduction; it can effectively prevent sound from spreading.   Grade A1 incombustible materials.   Easy for construction; cutting at will.   Antisepsis, ageing resistance, and anticorrosion, ensuring a healthy environment.   Strong moisture resistance can effectively prevent steam from permeatingScope of application:It is widely used for heat insulation and sound absorption in steel structures, industrial workshops, warehouses, public facilities, exhibition centers, shopping malls, and a variety of indoor playgrounds, sports stadiums and etc.
