Acoustic Room Divider
Acoustic Room Divider
Description
Acoustic room dividers structure rooms and contribute to pleasant room acoustics. Design motifs and desired colors make work environments inspiring and representative; the acoustic benefit remains effective on both sides. Freiraum manufactures all elements individually according to selection, in desired size and, on request, also as an XXL format or as part of a larger room concept. Room dividers are particularly suitable for open office structures, waiting areas, or multifunctional rooms where visual privacy and acoustic calming are to be combined.
