OSB3 Structural Board 18mm | 2440mm x 1220mm | 8ft x 4ft
High-Performance Structural Sheathing
Our OSB3 (Oriented Strand Board) is a high-precision, engineered wood panel designed for structural use in humid conditions. Manufactured by compressing layers of wood strands with moisture-resistant resins, it offers superior load-bearing capacity and dimensional stability compared to traditional plywood. At 18mm thick, this 2440mm x 1220mm (8x4) sheet is the industry standard for roofing, wall sheathing, and flooring. Engineered for Durability & Precision
Unlike natural timber, OSB3 is free from knots, voids, and core laps, ensuring consistent strength across every square inch of the board. It is specifically "Conditioned" for use in environments where incidental moisture or high humidity is expected, making it the ideal choice for flat roof decking and timber frame wall panels. Sustainable & Efficient Construction
This board is produced from fast-growing, small-diameter logs sourced from FSC-certified forests, making it one of the most environmentally friendly structural panels available. The smooth, consistent surface is easy to saw, drill, and fix with standard woodworking tools, providing a reliable substrate for felt, bitumen, or GRP roofing systems.
