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 (1 mm polyester fabric, 220 g/m², printable on both sides). Available in project-specific sizes; acoustic classification based on a 1000 × 2000 × 50 mm reference element. Three mounting variants: Z-rail (standard wall mounting, closed frame, 25 mm drilling distance to the top edge of the frame), L-rail (closed frame, recommended from 4 m² panel area, 63 mm wall clearance) or optional ceiling mounting with wire ropes (frame with function groove).
