Aluminium profiles with acoustic fleece ALU AKUSTIK®

The Aluform acoustic fleece improves the acoustics of rooms via the absorption of sound waves. It is glued onto the back of the different perforated aluminium profiles in order to optimize the sound absorption of ceiling systems.

The absorption degree alpha indicates how high the percentage of the absorbed sound waves is.
This degree depends on the distance between the perforated panels andthe solid ceiling, as well as on the hole percentage of the perforation. The Aluform acoustic fleece has been examined with respect to fire protection properties according to DIN 4102 and has been allocated to class B 2. In connection with the corrugated profile 18/76, the Aluform acoustic fleece has been subjected to a testing of the degree of sound absorption according to DIN EN ISO 354 and has been allocated to the sound absorption classes D and C.
