Through coloured facade boards have extremely natural appearance and premium quality
Boards are reinforced with mineralized cellulose fibres, they have smoothed surface and rectified edges
Twelve different through colored shades give StoneREX Palette boards an extremely natural appearance, which is their main feature. Its excellent mechanical characteristics make it one of the most suitable cladding materials for reliable, elegant and high quality solutions. Masscolored cement fiber boards are asbestos free double pressed and autoclaved flat sheets. Boards are reinforced with mineralized cellulose fibres, they have smoothed surface and rectified edges. They are through coloured and respond to the European standards EN 12467:2012.
