Grain

Lightly textured, natural mineral acoustic surface

Natural, delicately textured surface with powerful sound absorption

Acoustic Plaster Grain offers a lightly textured, seamless mineral surface designed to let sound pass through and attenuate within the mineral wool layer beneath. The result is a naturally granular finish that effectively absorbs unwanted reverberations, enhancing the acoustic comfort of interior spaces.

Available in an extensive palette of colors, Acoustic Plaster Grain can be specified as a 48mm or 28mm system and applied seamlessly to flat or curved surfaces of up to 2000ft², delivering a subtle, high-performance finish.
