Fine

Refined, natural mineral acoustic surface

Powerful sound absorption with an elegant aesthetic

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

Available in an extensive palette of colours, Acoustic Plaster Fine can be specified as a Class A or Class B system and applied seamlessly to flat or curved surfaces of up to 100m², delivering an elegant, high-performance finish.
