Description
Baffles absorb sound on both sides and leave the ceiling between them free. The baffle field is therefore suited to rooms with a densely occupied ceiling due to lighting or fire protection installations and is the first choice for acoustically improving thermally activated cooling ceilings. The absorber has a fleece-like texture and is available in black, mottled grey or white similar to RAL 9010. In this version it is fixed with adhesive dots directly beneath the ceiling.
