Description

The SUAM Universal Absorber is the acoustic basic system made of thermally bonded polyester fiber. It has been accredited and tested by TÜV Rheinland in numerous configurations and achieves αw 1.00, absorber class A, in the basic configuration (80 mm, with wooden frame). Available in 15, 25, and 80 mm material thickness. The TÜV measurements cover flat installations, block arrangements, and suspended variants. Use as wall, ceiling, or block absorber, free-hanging or directly mounted. All variants are binder-free, 100 % recyclable, and meet fire class B1 according to DIN 4102. Over 1,000 color variants available.
