Acospray is a seamless acoustic spray plaster. Acosorb applies the product in one phase to any surface, in any desired thickness on walls and ceilings of any size. The product is available from fine to coarse texture and in an extensive range of colours. This spray plaster is primarily composed of recycled natural cellulose fibres. By blending with additives, Acosorb optimizes durability and fire safety. In a thickness of 3.5 cm, sprayed directly onto the substrate, an alpha w = 1.0 is achieved.
