Two out of three winning completed houses of the Wooden Building of the Year 2011 competition were constructed with Rigips fiber-reinforced and gypsum board systems. For both external and internal load-bearing walls, structures with cladding made of Rigidur fiber-reinforced boards were chosen. Rigidur fiber-reinforced boards are load-bearing structural boards made from gypsum, paper fibers, and other additives, pressed under high pressure. They have excellent mechanical, acoustic, and fire-resistant properties. The boards are intended for universal use as construction, fire-resistant, and impregnated materials.
