Acoustic Plaster System is a beautiful smooth mineral surface with powerful sound absorption. Made in the UK from a minimum of 72% recycled material, it can be installed seamlessly over large expanses of flat, curved and vaulted ceilings as well as high level walls.

Over 35 years of expertise in the formulation of marble based plaster finishes have created a clean, elegant finish that still allows sound energy to pass through the surface. This enables sound to be absorbed and attenuated in the layer of natural mineral wool beneath, improving the quality of well being in interior spaces.
