Moved two walls in a bathroom and need to complete the ceiling plasterboard. The existing boards are 9 mm thick and 600 mm wide with a beveled edge. I have checked the websites of Danogips, Norgips, and Gyproc, but 9 mm ceiling plasterboard doesn’t seem to be available anywhere. It seems I might have to tear down the entire ceiling and replace it with 13 mm. :-/
Does anyone know if 9 mm ceiling plasterboard is still available somewhere?
