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. Acoustic Nonwoven is manufactured in 130 gr and 80 gr weight per square metre. Roll width is 1275 mm, roll length is 250 metres. Unrolling cost in the case of a shared roll €53 per occasion.
