Quad FeltForms Ceiling Tiles

4 tiles

FeltForms ceiling tiles are designed to dampen noise while increasing sound clarity and speech intelligibility in spaces with 2 x 2 drop ceiling grids. FeltForms modern patterns and beautiful felted textures transform the acoustics and aesthetics of lay-in ceilings. The tiles are designed as a tool kit for improving sound in a variety of environments including living rooms, home theaters, restaurants, lobbies and conference rooms. Quad Ceiling Tiles provide a combination of absorption and diffusion. This combination reduces reverberation but additionally scatters directional sound, controlling flutter and slap-back echoes while retaining a certain amount of “live” room characteristics. This is adequate for a “warmer” sound in classical and background music program. For volume pricing, custom designs and colors contact us!
