The Knauf GKB expansion board is a handy, floor-to-ceiling one-man panel for easy and quick installation as a dry plaster in interior fittings. The gypsum board can also be used as a load distribution board on Knauf dry fill, but is not suitable for stud constructions due to the low board thickness (9.5 mm). The Knauf expansion board is dimensionally stable and resilient, easy to process, non-flammable and free of harmful substances.
