    Description

    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.

    Features & Benefits

    • OSB3 classification: Suitable for structural, load-bearing use in humid service conditions (Service Class 1 & 2).
    • 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.
    • Smooth, uniform surface: Suitable for direct coverings or secondary finishes.
    • Workable timber panel: Can be cut, screwed, nailed, or glued using standard tools.
    • Board length 2400mm (8ft): Designed for rapid installation across joists or rafters.
    • Thickness 18mm, width 590mm: Provides reliable structural strength with manageable handling.


    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.
    • Fixing method: Panels can be screwed or nailed directly to joists or rafters; secret nailing is recommended for a flush finish.
    • Moisture protection: For permanent external use, apply exterior paint and a waterproofing sealant, allowing full drying before installation.

    Compliance & Performance

    • Preservative treatment / classification: OSB3 manufactured with waterproof adhesives and edge-sealed for resistance to swelling in humid environments.
    • Service class: Classified for use in Service Class 1 (dry) and Service Class 2 (humid) applications in line with BS EN 300.
