Textile-covered wall absorber

Wall

Description

The textile-covered wall absorber is frameless and is supplied pre-assembled so that it can be fixed directly to the wall with a mounting rail. Thanks to its low weight, mounting is easy to carry out on all wall surfaces. The covering is available in polyester, pure new wool, blended fabrics or non-combustible glass fabric in over 300 colours and textures; a display fabric can optionally be stretched over it as a projection surface. If required, non-combustible material of class A2 per DIN 4102-1 is available.
