This PLANK 19mm plasterboard is appropriate for dry lining internal surfaces or linings in places such as lift shafts, stairwells or auditoriums. It is moderately effective as a sound and moisture resistant plasterboard. It also provides a certain amount of resistance when exposed to temperatures above 49°C.
