Les plaques de Fermacell boards are composed of 80% gypsum (sedimentary rock component of plaster) reinforced with cellulose fiber, derived from recycled paper (20%), without chemical additives.
The mixture of these natural components with additional water is then compressed at high pressure and dried at high temperature to obtain a board with an incomparable rigidity.
