SilentFiber

SilentFiber offers a broad portfolio of sustainable acoustic elements made from natural fibres. The product family ranges from the peat-based SilentRoot acoustic panel through the hemp-based SilentHEMP line to specialty products such as SilentSPA (wet room), SilentMOSS (moss picture) and SilentBEE (hexagon). Owner Dipl. Ing. Robert Schwemmer operates as a brand owner with selected European manufacturing partners. Custom formats and individual cutting are available from the first panel onward (max. 1.2 × 2.4 m). Awards: Green Product Award 2022, Klimaschutzpreis (Climate Protection Prize), Austrian Bauherrenpreis, Green Product Award Finalist 2026.

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.

Technical data

Material: Peat-fibre acoustic panel made from surface peat, custom-printed motif

Surface: Direct print onto the matt, porous fibre face; the panel texture stays visible and the motif appears slightly darker

Up to fire class: B-s3,d0 per EN 13501-1:2018 (low flammability)

Application: Acoustic pictures as motif walls in conference rooms, foyers, stairwells, corridors and reception areas
