Acoustical Solutions, Inc. AC100B 隔音和隔音材料

The Signature Sound Barrier Ceiling Tile is a double duty soundproofing ceiling tile. It works for both lowering sound transmission as well as reducing reverberation. The ceiling tile consists of a 1\" thick 6 pound density fiberglass covered with your choice of four facings. This fiberglass is an excellent sound absorber, which has a NRC rating of .80. Attached to the back of the fiberglass is a layer of our AudioSeal™ Sound Barrier with an aluminized facing. This adds a strong soundproofing material, STC rating of 27, which is not found in standard acoustical ceiling tiles. These sound barrier ceiling tiles are Class 1 fire-rated and come in standard sizes of 2' x 2' and 2' x 4' and standard thickness of 1\".
