Clay drybuilding


Wood fibreboard for cladding of wood and metal post structures of inner walls, facing shells, ceiling and roof surfaces. CLAYTEC HFA N+F are light and breathable. The small format and the tongue-and-groove ensure best workability, even joints are possible in the field. It is very reasonably priced, making drywall affordable for everyone! As supplement to this product sheet the CLAYTEC Guidelines for ecological drywalls in system apply
