Description

aPerf® panel, formerly aPerf board, is the self-supporting polyester acoustic board of the aPerf® family and the base material for wall panels, ceiling clouds, desk dividers and furniture. Needing no frame or cover, it can be cut like particleboard into clouds, discs and free forms with grooves or rebates, and printed or painted. It mounts directly or with an air cavity on Z-rails or rebate battens, optionally with bass trap inserts, or hangs from steel cables or as a baffle.
