SKY HORIZONTAL

CeilingFree-hanging

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 (1 mm 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.
