Acoustic Plaster

Pleasant acoustics with a smooth finish. Acoustic plasterwork improves the acoustics in any room. This exclusive product has been developed in-house and is only offered by Acosorb. Acosorb 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.


Acosorb acoustic plaster is available in two different thicknesses: 3mm and 32mm, with a smooth finish in a colour of your choice. The colours gold and silver have been added recently.
