Acoustical Plaster in London

London Acoustic Plaster

Acoustic Plasters are the solution for noisy rooms

Pleasant acoustics with a smooth finish. Acoustic plasters improve the acoustics in any room. This unique product has been developed with wellbeing in mind and is only offered by Quiet Interiors. Quiet Interiors plaster is completely seamless and can be applied directly to the architectural substrate or on a lowered construction. The plasterwork consists of acoustic board material that is seamlessly finished with an acoustic transparent plaster layer. This breaks down sound energy and creates a pleasant acoustic climate.

Quiet Interiors acoustic plaster is available in four different thicknesses: 30mm, 40mm, 50mm and 70mm with a smooth finish in a colour of your choice. The colours gold and silver have been added recently.
