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
SKY HORIZONTAL is a horizontally suspended acoustic panel from the ALU LINE by SCHALLSAUGER. It offers an economical alternative to a full acoustic ceiling: individual panels suspended on wire ropes, available in almost any size and achievable seamlessly up to 20 metres in length. The powder-coated aluminium frame (all RAL colours on request) is designed as a closed frame for ceiling mounting. The akustikTex covering (0.04 in polyester fabric, 220 g/m²) can be individually printed. Installation uses wire ropes with a screw cap, ceiling fastener, and wire rope holder with T-nut for the function groove in the frame.
