Acoustical Surfaces' Sound Silencer™ tackable ceiling and wall acoustic panels provide high-performance sound control with a clean, modern finish. Made from rigid, porous ARPRO Acoustical Porous Expanded Polypropylene (P.E.P.P.), these lightweight panels deliver both sound absorption (NRC) and sound blocking (STC) — offering an effective, versatile solution for noise reduction across a variety of interior settings.
With a Class A fire rating (ASTM E84) and a non-fibrous, impact-resistant surface, Sound Silencer™ panels are ideal for projects where durability, hygiene, and acoustical performance are critical — including gymnasiums, natatoriums, clean rooms, laboratories, food prep areas, firing ranges, and high-moisture environments.The cleanable acoustic panels can be applied directly on wall and ceiling surfaces, installed with adhesives, direct attach, or lay-in for attractive and effective sound control.
