Acoustic Nonwoven

The surface of many of our products is a variation of polyester nonwoven. With its airpermeable, micro-perforating qualities the sound is reflected at a minimum when hitting the surface, so that the sound absorbent can absorb at maximum. It can stand dampness, is free from smell, does not rot or mould and does not cause any allergic reactions.

Fields of application

  • Concerthall
  • Music studio
