Manufacturer
Acosorb
Acosorb (Acosorb GmbH, Bocholt) develops and applies seamless acoustic spray and gypsum plasters (acoustical plaster). The jointless wall and ceiling surfaces absorb sound, reduce reverberation, and keep a continuous look, with no visible joints, grids, or tiles. The spray plasters (Acospray range) consist of enriched, partly recycled cellulose fibers with a water-based binder and are sprayed on in several crosswise layers. Acoplaster F combines a noncombustible mineral wool board with an acoustic plaster top layer. Sound absorption depends on layer thickness and build-up. The materials are vapor-permeable and hygroscopic (usable even in swimming pools and semi-outdoor areas), Cradle to Cradle Bronze certified, and documented by an ISO 14025 EPD (MRPI) and VOC test evidence from Fraunhofer. Member of the DGNB. Reference projects in Germany and the Netherlands.
Description
The Acosorb Green Line is the most sustainable version of the Acospray range: an acoustic spray plaster made from 100 % post-consumer recyclate (recycled cellulose fibres). Available in the recyclate shades Apple Grey, Billboard Grey, Hong Kong Grey and India Yellow. Acoustically the Green Line matches its respective base spray plaster. The absorption values stored here are those of the DC3 base (coarse-grained spray texture, 0.39–2 in); for the fine DC2 versions (India Yellow, Hong Kong Grey) the DC2 values apply.
