Typical Applications:
Gyptone perforated plasterboard is typically used as a high performance plasterboard for ceilings in commercial constructions where a high level of acoustic performance is required. This includes applications such as theatres, restaurants, shopping centres and hotel foyers. Whilst perforated plasterboard in predominantly installed in ceilings, it is suitable for use in walls.
Gyptone joints are finished with a three coat jointing system and sanded smooth prior to decoration.
