OSB T&G Board ? Interlocking Strength for Flooring & Roofing

Our OSB Tongue & Groove (T&G) Boards are high-performance, engineered panels designed to create a tight, secure fit between boards? perfect for load-bearing applications such as floor decking, roof decking, and loft panels. The interlocking tongue and groove edges provide superior joint strength, stability, and easier installation compared to square-edged boards.

Made from multiple layers of wood strands bonded with waterproof adhesives, OSB T&G boards deliver long-lasting durability even in demanding environments.

• Tongue & Groove Profile: Precision-machined edges ensure tight, secure joins with reduced movement.
• Structural Grade (OSB/3 or OSB/4): Suitable for load-bearing use in humid or dry conditions.
• Durable & Stable: Engineered for strength, with excellent resistance to warping or swelling.
• Ideal for Flooring: Suitable for domestic and commercial subflooring, including under carpet, tile, or wood.
• Standard Sizes: Commonly 18mm or 22mm thickness, with sheet sizes like 2440 x 590mm or 2400 x 600mm.
