fermacell® gypsum fibre board

fermacell® gypsum fibre boards consist of recycled paper fibres, gypsum and water and are pressed under high pressure – without any further binders – into stable and odourless boards. Constant quality and quality controls through self-monitoring, laboratory tests and official materials testing institutes ensure consistently high quality.

The special manufacturing process and the homogeneous mixture of natural raw materials make the gypsum fibre boards stable, resilient and resistant to mechanical stresses. They can be used universally as building, fire protection and damp-proof panels and also ensure a good indoor climate – tested by building biology.
