Ceiling Raft

EPD availableFree-hanging

Description

Free-hanging metal ceiling raft for flexible room acoustics, available as a single-piece or multi-piece version with a 55° or 90° folded edge. It can also be installed retrofit, without modifying the existing lighting. It can be combined with a cooling and heating function for later climate retrofitting. The structural ceiling remains visible and accessible for maintenance. Available formats: 2.88 m² (2.4x1.2 m), 3.45 m² (3x1.15 m), 1.35 m² (3x0.45 m), 2.70 m² (3x0.9 m), 4.05 m² (3x1.35 m), 2.88 m² (4.8x0.6 m), 3.60 m² (3x1.2 m), 1.96 m² (1.98 x 0.99 m).
