AKUSTItrenn Acoustic Partition

Description

AKUSTItrenn is a partition and screen element from BVS, micro-perforated on both sides, made from a double-sided acoustic wood-fibre insulation board with an integrated insulation layer. The visually calm micro-perforation on both sides is produced with hole diameters of 1 mm (standard) through 1.5 and 2 to 2.5 mm as well as grids from 4 to 8 mm and a staggered 6/3 mm grid. The integrated insulation layer removes the need to build up multi-layer partitions by hand; direct edge banding produces high-quality components with predictable absorption values. The edge-free perforation allows precise cuts for demanding geometries and the integration of glazing, doors, switches and other components, while reinforced edge sections for fittings as well as cuts and cut-outs are possible directly on site. The entire panel build-up is bonded formaldehyde-free to the NAF standard and is therefore low in emissions. Elements are produced up to 3010 mm in length and 1300 mm in width with margin widths to order and are suited to fixed and mobile interior fit-out as well as exhibition construction. Acoustically, AKUSTItrenn works through the interplay of the micro-perforation on both sides with the wood-fibre insulation behind it, which damps the sound inside the element and keeps both sides of the room absorbent. The sound absorption coefficient 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 single-number rating. In addition, the sound insulation of the element is documented as the weighted sound reduction index Rw per EN ISO 10140-2, so the component addresses both the reverberation time in the room and sound transmission between the separated areas.
