Acoustical Surfaces Sound Silencer™ acoustical sound panels are made from Rigid Porous ARPRO Acoustical (P.E.P.P.) Planks and are Class A fire rated with both STC and NRC values. Sound Silencer panels are lightweight, impact-resistant, moisture-, bacteria-, & fungi-resistant, with a tackable surface. They work especially well for gymnasiums, ice rinks, swimming pools, clean rooms, laboratories, food prep areas, firing ranges and anywhere else where noise control is important. Panels can be applied directly to wall and ceiling surfaces for effective sound control.
