SilentPICTURE Acoustic Picture

Name: SilentPICTURE Acoustic Picture
Brand: SilentFiber

EPD availableWallCeiling

Description

SilentPICTURE is the printed-motif version of the SilentRoot Torf acoustic panel. A custom-supplied image is printed directly onto the matt-porous fibre face — the fibre structure remains visible and the motif appears slightly darker after printing. Ideal where wall art and sound absorption should combine in a single element: conference rooms, corridors, stairwells, foyers. Maximum format 1.2 × 2.4 m per panel; larger wall pictures can be assembled from multiple panels (for example a 3.2 m wide composition from two pieces). Individual sizes from the first panel, four thicknesses (20 / 30 / 40 / 50 mm). Acoustic values are identical to SilentRoot: αw between 0.50 and 1.00 depending on wall standoff. The underlying measurements were carried out by Akustikverkstan Sweden in an accredited reverberation room per DIN EN ISO 354 + ISO 11654.
