What is an acoustic spray plaster solution?


An acoustic spray plaster solution is an extremely flexible seamless sound absorption solution. It’s a non-perforated, monolithic system consisting of a mineral fibre panel with a layer of micro-porous plaster. Our acoustic spray plaster system, the Absorb-R GypLine αw is a flexible plaster that behaves as a membrane sound absorber providing excellent sound absorption through the entire frequency range. It is non-combustible (A2-s1, d0) and can be installed on flat, horizontal, vertical and pitched surfaces, vaulted ceilings and surfaces with irregular forms. It can be used in large areas with no need for expansion joints.

Where can acoustic spray plaster be used?

This seamless and complete solution can be adapted to a wide range of rooms, from home use, office space to conference halls, auditoria, theatres, recreational sports and educational areas. The Absorb-R GypLine αw is environment-friendly, fully recyclable and has natural components that offer optimal sound absorption with extensive resistance to fire.

Does acoustic spray plaster work?

Our acoustic wall spray and acoustic ceiling spray has a structure that once applied acts as a membrane absorber reducing sound reflections making this product an excellent sound absorption solution. Our spray-on acoustic system dampens noise, absorbs airborne noise thus contributing to restful acoustics within educational, leisure, residential, industrial and public spaces.
