Description

The Absorber stretch ceiling is a fabric covering system for ceiling or wall installation that is visually indistinguishable from an ordinary ceiling. It can be stretched across the full surface up to the walls or installed as a suspended system covering partial areas. The covering comes in white or black as standard, optionally printed with a motif or colour of choice. Existing or new ceiling installations such as lighting, air-conditioning or security systems are integrated into the system.
