How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.

Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.

What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview
Structural hardwood plywood board, measuring 2440mm x 1220mm (8' x 4') with a 15mm thickness.
Made from cross-laminated hardwood veneers, kiln-dried and bonded with moisture-resistant adhesive, classified to EN636-2 (suitable for humid interiors or sheltered exteriors when sealed), it provides high strength, stability, and impact resistance.
Widely used for partitions, subfloors, and medium-span structural work, the smooth hardwood face is pre-sanded, allowing for painting, staining, or clear finishing where appearance matters.
Features & Benefits
- Cross-grained veneer construction: Alternating layers distribute weight evenly, reduce warping, and improve strength in tension and compression.
- Moisture-resistant: EN636-2, suitable for humid interiors or exterior use when treated and sealed.
- Hardwood face veneers: Smooth, sanded surface can be painted, stained, or clear finished for decorative use.
- Durability: Designed to resist bending and surface distortion under load.
- Strength-to-weight ratio: Provides reliable performance in demanding flooring, decking, and roofing applications.
- Standard sheet size (2440mm x 1220mm): Compatible with common framing centres, easy to cut, and minimises waste.
- Thickness 15mm: Robust panel suited to subfloors, partitions, and medium structural spans.
Please Note: Colour and finish are representative only and may vary slightly as this is a natural product.
Applications
- Flooring: Functions as a structural subfloor when installed across joists spaced at appropriate industry-standard intervals.
- Heavy-duty workbenches: Provides a high-strength, impact-resistant surface suitable for intensive workshop environments.
- Furniture frames: Used for primary carcass construction in heavy-duty wardrobes, tables, and large storage units.
- Roof decking: Suitable for flat or pitched roof decks on outbuildings when the span is correctly matched to the board thickness.
- Mezzanine floors: Utilised for platform construction in domestic or light commercial storage areas to increase usable floor space.
- Exhibition stands: Applied in the construction of reusable display platforms and structural wall panels that require a paintable finish.
- Van flooring: Serves as a durable, impact-resistant floor lining for commercial vehicles to protect the metal chassis and provide a secure fixing base.
- Internal partition skins: Used in high-traffic commercial environments (like corridors) where standard plasterboard lacks sufficient impact resistance.
Installation Guidance
- Condition the boards: Store panels flat in the environment where they will be installed for 48 to 72 hours to allow moisture content to stabilise.
- Maintain expansion gaps: Leave a 2mm to 3mm gap between sheet edges and a 10mm to 12mm gap at room perimeters to allow for natural thermal and moisture movement.
- Seal all edges: Apply a high-quality wood sealer or primer to all factory and site-cut edges immediately to prevent moisture ingress and swelling.
- Space fixings correctly: Secure boards with screws or nails at 150mm intervals along the sheet perimeter and 300mm intervals on intermediate supports.
- Position joints on supports: Ensure all short-edge joins fall directly over a joist or noggin to maintain structural continuity and prevent deflection.
- Use compatible fasteners: Utilise galvanised or stainless steel fixings to prevent corrosion and potential staining of the hardwood face in humid conditions.
Compliance & Performance
- Service class: EN 636-2, verified for use in humid internal conditions or protected exterior applications.
- Bonding quality: EN 314-2 Class 2, ensuring the glue line performance is maintained in humid environments.
- Structural certification: CE/UKCA marked for use in permanent construction, meeting BS EN 13986 standards.
- Important note: This product must be fully sealed on all faces and edges with an appropriate preservative or microporous coating if used in sheltered exterior locations to prevent moisture-related degradation.
