Product Overview
18mm OSB3 tongue-and-groove flooring board, measuring 2400mm x 590mm (8' x 2').
Each board is manufactured from strands of softwood arranged in cross-oriented layers, bonded with moisture-resistant resin, and hot-pressed to form a dense, structural panel with excellent strength and stability.
The tongue-and-groove edges are precision-machined to ensure a tight interlock between boards, helping to minimise deflection, reduce squeaks, and produce a flush, even surface ready for direct coverings.
With its OSB3 classification, the panel is designed for load-bearing use in both dry (Service Class 1) and humid (Service Class 2) conditions, making it a dependable choice for flooring, flat or pitched roofing, and wall sheathing where durability and moisture resistance are critical.

- Engineered from oriented wood strands with resin binders: Provides resistance to rot, fungal decay, and swelling.
- Tongue-and-groove edge profile: Ensures secure jointing, reduces movement, and creates a flush surface.

Please Note: Colour and finish are representative only and may vary slightly as this is a natural timber-based product. Additional weatherproofing is recommended if used externally for prolonged exposure.
Applications
- Roof decking: Reliable choice for structural roof build-ups in humid service conditions.
- Wall sheathing: Provides racking strength and structural stability in timber frame construction.
- Furniture and fit-out use: Can be adapted for non-structural purposes such as signboards, furniture, or concealment panels.
- Mezzanine flooring: Structural 18mm thickness provides a rigid, high-capacity decking solution for industrial platforms and storage mezzanines.
- Garage flooring overlay: Moisture-resistant OSB3 construction creates a durable, thermally improved floor surface when installed over concrete bases with a suitable damp proof membrane.
-
Garden room and office flooring: Certified structural board provides the necessary load-bearing capacity for habitable timber-frame buildings in compliance with building regulations.
Installation Guidance
- Tongue-and-groove jointing: Boards slot securely together; edges may also be glued for added stability.
