SCHALLSAUGER (KASPER GmbH)
SCHALLSAUGER is the acoustics product brand of KASPER GmbH in Rielasingen-Worblingen on Lake Constance. Founded in 1977, the family business manufactures printable fabric absorbers, LED-integrated acoustic panels and frameless wall and ceiling solutions on 26,910 sq ft of production space. The ALU LINE, FRAMELESS, LIGHTBOXX, MONO-LIT and ORION 8 product ranges cover wall, ceiling, room-divider and lighting applications. All covering fabrics (akustikTex) are certified to Öko-Tex Standard 100 and fire-tested to DIN 4102 B1 / EN 13501-1 B-s1,d0. Acoustic measurements were determined by the Fraunhofer Institute for Building Physics (IBP) to DIN EN ISO 354 (test report S 10734-Alpha, 2014).
Description
SCHALLSAUGER WALL is the ALU LINE picture wall for wall mounting: a wall-mounted acoustic absorber with individually printable fabric covering. As early as the turn of the millennium, SCHALLSAUGER was the first manufacturer to bring large-format acoustically effective picture walls to market. Motifs from the in-house image archive with a three-dimensional effect can be printed onto the akustikTex surface. Construction: powder-coated aluminium frame (all RAL colours on request) with akustikTex covering (0.04 in polyester fabric, 220 g/m², printable on both sides). Available in project-specific sizes; acoustic classification based on a 39 × 79 × 2 in reference element. Three mounting variants: Z-rail (standard wall mounting, closed frame, 0.98 in drilling distance to the top edge of the frame), L-rail (closed frame, recommended from 43 sq ft panel area, 2.5 in wall clearance) or optional ceiling mounting with wire ropes (frame with function groove).
