COPERSOUND PE is a rolled multi-layer product for acoustic insulation of partitions walls, composed by a bitumen polymer membrane with green fabric surface finishing coupled on the upper face to a sound resistant expanded/reticulated closed-cell polyethylene layer - density 33 kg/m3.
The sound insulating bituminous membrane ensures watertightness, resistance to water vapor diffusion and, at the same time, improves acoustic insulation performance by acting as a continuous barrier against airborne noise transmissions.
The physical reticulation of the sound resistant PE layer and the water tight closed-cell structure allow the product to have remarkable long lasting sound & heat insulating properties.
