AKUSTIpan green silence Acoustic Panel

Description

AKUSTIpan green silence is an acoustic panel made from untreated solid spruce, produced as an 18 mm glued lamella with a stable finger-jointed bond. The spruce comes from sustainable forestry, the wood remains low-emission and this is documented by an emissions test to DE-UZ 38. The face is slotted at 2, 3 or 4 mm, the back carries openings and is optionally fitted with acoustic fleece. The panel is offered on a 16 mm grid (2940 x 160 x 18 mm) and a 32 mm grid (2940 x 192 x 18 mm), on request with irregular slotting to minimise the moiré effect. The edges are formed as a tongue-and-groove joint, producing a seamless continuous look; the surface can be left sanded raw, oiled, waxed or lacquered with water-based paints. Cuts, cut-outs and beam integrations can be carried out directly on site, which also makes the panel suitable for work on existing buildings. Acoustically, the panel only works through the interplay of the slotting on the face, the openings on the back and the build-up behind it: slot width and build-up depth determine in which frequency range sound is absorbed, and can be adjusted at no extra cost through the slot spacing. Sound absorption is determined in the reverberation room per EN ISO 354 and rated per EN ISO 11654; for design work the full third-octave curve matters alongside the weighted single-number rating, and not the individual figure alone.
