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 2,500 m² 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 FRAMELESS BAFFLE is a vertically suspended acoustic baffle made of thermally bonded polyester nonwoven for sound absorption in tall rooms. The C-rail mounting system allows individual baffles to be repositioned later, so the acoustic damping effect can be flexibly adapted to how the room is used. Material: SCHALLSAUGER FRAMELESS, thermally bonded nonwoven made of 100% PES staple fibres, area weight 3200 g/m², thickness 50 mm. Made 60% from recycled PET bottles, 100% recyclable, fire class C-s2,d0 per DIN EN 13501-1 / B1 per DIN 4102-1. Available in white, mottled light grey or black; lacquered in any RAL colour on request without acoustic disadvantage. Standard formats 200 × 35 cm and 100 × 35 cm. Custom sizes between 60–236 cm in width and 35–150 cm in height; maximum delivery length 235 cm. Several mounting variants: C-rail with wire-rope suspension (FLBDC) or with screw connection (FLBDC0), direct ceiling connection without rail (FLBD2), plug-in plate fastening as a cost-effective alternative (FLBDS / FLBDSC / FLBS) or Odenwald ceiling-clip adapter for grid ceilings (FLZDOWA). Axis spacing of the suspension is 0.5 × baffle width by default. Mounting hardware in black, white or light grey.
