AKUSTIpan SL Acoustic Impact Wall

Description

AKUSTIpan SL Prallwand is the ball-impact-resistant acoustic panel from BVS with a linear structure, produced as a three-layer spruce board or as birch plywood. The fine slotting on the face with drilling on the back gives the element a modern, joint-free look and makes it acoustically effective. Slot widths are 2 and 3 mm on a 16 mm or 32 mm grid as well as in irregular slotting; the drilling diameters on the back are 6 and 4 mm for spruce and 8 mm for birch plywood. A ball-impact-resistant tongue-and-groove connection allows concealed screw fixing, a seamless appearance and quick installation; cuts and cut-outs are possible directly on site. The spruce version is made from wood from sustainable forestry, formaldehyde-free special adhesive and environmentally friendly lacquer, and is therefore low in emissions. Acoustically, the impact wall works through the interplay of the slotting on the face, the drilling on the back and the build-up behind, which turns the panel into a broadband sound absorber. Absorption coefficients are 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 single-number rating alone. Across the different slot and grid versions, absorption can be tuned specifically to the requirements of the room.
