Schallsauger ALU LINE SKY VERTICAL

Name: Schallsauger ALU LINE SKY VERTICAL
Brand: SCHALLSAUGER (KASPER GmbH)

SKY VERTICAL

Free-hangingFreestanding

Description

SKY VERTICAL is a vertically suspended room divider from the ALU LINE by SCHALLSAUGER. The free-standing modules acoustically separate open-space areas and create a semi-transparent, understated zoning without removing the open character of the room. Double-sided sound absorption: each screen, measuring 1000 × 2000 × 50 mm, absorbs sound on both sides. The akustikTex covering (1 mm polyester fabric, 220 g/m²) is individually printable; the powder-coated aluminium frame is available in all RAL colours. Mounting is via wire ropes with a screw cap and ceiling fasteners (the scope of delivery includes wire rope holders with a T-nut for the frame's function groove). Optionally couplable vertically beneath one another.
