Since 2004, freiraum Akustik has developed custom-made acoustic art panels, room dividers, desk partitions and ceiling rafts for offices, medical practices, meeting rooms and residential spaces. The focus is on combining effective sound absorption with individual design, art motifs, custom colours and personal acoustic consulting all the way through to installation.
WebsiteAcoustic Ceiling Raft in Custom Colors
Acoustic ceiling rafts are an elegant and highly efficient way to improve room acoustics over large areas. They utilize unused ceiling surfaces to absorb sound early and significantly reduce reverberation in offices, meeting rooms, waiting areas, and living spaces. Freiraum Akustik produces all ceiling rafts individually according to selection, in custom sizes and on request also in XXL formats or as part of complete room concepts. Colors and formats are coordinated with the interior. The elements combine high sound absorption with a dimensionally stable frame construction, low-emission materials, and ready-to-install delivery.
