18mm OSB3 Tongue & Groove Flooring Board - 2400mm x 590mm

This 18mm OSB3 Tongue and Groove Flooring Board is designed for strong, stable and reliable floor construction. Made from layered wood strands that are bonded under pressure to create a dense structural panel, it provides consistently even strength across the board without knots, voids or weak grain.

The tongue and groove profile allows each board to lock securely into the next, producing a firm, level surface with reduced movement between joists. This helps prevent floor flex, creaks and uneven finishes, making it suitable for both new-build projects and refurbishments.

With its OSB3 rating, the board can be used in humid environments, making it a dependable solution for flooring, roof decking, timber frame systems and sheathing where moisture resistance is required.
