Creating calm and inviting spaces.

Acoustic Plaster allows sound energy to pass through the mineral-based surface and attenuate in the layers below, reducing reverberations that can otherwise impact the enjoyment of the space. Absorbing unwanted sound, Acoustic Plaster helps create calm, restful spaces that support the wellbeing of those using them.

Made in the UK from a minimum of 72% recycled material, Acoustic Plaster can be seamlessly installed over large expanses of flat, curved and vaulted ceilings as well as high level walls. The system is also suitable for well-ventilated areas exposed to moisture, such as swimming pools.
