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 2 in. 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 79 × 14 in and 39 × 14 in. Custom sizes between 24–93 in. in width and 14–59 in. in height; maximum delivery length 93 in. 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.
