Description
This version consists of pieces cut from PET staple-fibre boards, mounted in a row on round aluminium tubes and suspended beneath the ceiling on stainless steel cables at a continuously adjustable height. The round tube is natural anodized (E6/EV1) or, on request, powder-coated in colour. Like the directly mounted baffle field, the construction is suited to ceilings with densely packed building services and to thermally activated cooling ceilings. The fleece is available in black, mottled grey or white similar to RAL 9010.
