Structur of the system:

Any stable ceiling and wall construction, such as concrete ceilings, plasterboard constructions or metal constructions, is suitable as a substrate.

The Sonaboard is glued to the existing ceiling construction with Sonaglue without visible seams. Sonacoustic PL1 is then sprayed-applied and troweled. After drying, the surface is sanded to achieve a perfect finish. Openings or separations to other surfaces can be finished with profiles.

With fire class A1, Sonacoustic PL1 is also suitable in environments with the highest fire protection requirements.
