This OSB3 Sterling Board combines structural strength with moisture resistance in a practical 1 525 × 610 mm format. The 18 mm-thick panel offers solid load-bearing performance in applications such as flooring, roofing, wall sheathing and temporary hoardings—even in humid conditions. You can cut, drill, nail or sand it easily with standard tools. It remains stable under stress and resists warping or swelling in damp environments.
