Product Overview
Structural OSB 3 Sterling board, measuring 2440mm x 1220mm (8' x 4') with a 15mm thickness.
Engineered from cross-laminated softwood strands and bonded with resin under heat and pressure, it delivers consistent strength and stability without knots or voids.
Certified to EN 300 OSB 3 for load-bearing performance in humid conditions, it serves as a practical and cost-effective alternative to plywood for many structural applications such as flooring, roofing, and medium-span structures.
Features & Benefits
- Structural classification: OSB 3 certified to EN 300, for load-bearing use in humid conditions.
- BBA approved: Permits use in a wide range of commercial and domestic projects.
- Void-free construction: Consistent strength with no knots or core gaps.
- Cross-strand stability: Resists warping, splitting, and expansion.
- Moisture performance: Reliable in humid environments, unlike OSB 2 (dry-use only).
- Workability: Easy to cut, drill, nail, and sand with standard tools.
- Board size 2440mm x 1220mm: Compatible with UK framing centres for straightforward fixing on standard stud/joist spacing.
- Thickness 15mm: Provides rigidity for floors, roofs, and medium-span applications.
Applications
- Timber frame structural panels: Acts as a primary component in housing systems, providing essential racking resistance and load-bearing capacity for floors and walls.
- Concrete formwork (shuttering): Provides high-strength containment for foundations and walls, serving as a robust alternative to shuttering plywood where a textured concrete finish is acceptable or the element is to be buried.
- Workbenches and heavy-duty shelving: Provides a rigid, deflection-resistant surface for garage and workshop tops supporting heavy machinery or tools.
- Roof decking: Acts as a stable, heavy-duty load-bearing base beneath membranes and primary roof coverings.
- Sarking: Used under the primary roof covering (like slates or tiles) to provide a secondary barrier and add significant rigidity to the roof structure.
- Site hoardings: Delivers a durable, moisture-resistant solution for secure temporary site enclosures and barriers.
- High-load structures: Ideal for platforms, staging, and demanding builds requiring high structural integrity.
- DIY and carpentry: Perfect for robust benches, shelving, and heavy joinery projects.
- Van and trailer lining: Rigid construction protects vehicle interiors from heavy equipment and shifting loads in professional transit applications.
Installation Guidance
- Allow for expansion: Leave a 3mm expansion gap between all board edges and a 10mm gap at rigid wall abutments to accommodate natural movement.
- Stagger the joints: Lay panels in a "brick-bond" pattern across supports to ensure structural loads are distributed evenly across the frame.
- Support all edges: Ensure every board edge is supported by a joist, stud, or noggin to prevent deflection and maintain a level surface.
- Apply correct fixings: Secure boards using galvanised nails or screws at 150mm intervals along edges and 300mm intervals on intermediate supports.
- Seal cut edges: Coat all field-cut edges with a high-quality water-resistant wood sealant immediately to prevent moisture ingress and edge swelling.
- Orient boards correctly: Install the long axis of the board perpendicular to the supporting joists or studs for maximum structural spanning strength.
- Protect from weather: Cover installed boards with a waterproof membrane as soon as possible if the structure is not yet fully weathered.
- Fixing distance from edge: Ensure all fasteners are driven at least 10mm from the board edge to prevent breakout and maintain pull-through resistance.
- Surface painting: Use a high-quality solvent-based primer or dedicated OSB sealer before applying topcoats to prevent strand swelling, as detailed in our comprehensive guide to painting OSB.
Compliance & Performance
- Standard: EN 300 OSB 3 classification, verified for structural use in humid environments.
- Certification: BBA approved for quality and compliance in construction.
- Bonding: High-pressure, resin-bonded layers provide long-term durability and resistance to delamination.
- Veneer quality: Free from internal knots and core voids, ensuring consistent structural integrity across the board.
- Important note: Colour and finish are representative only and may vary slightly as this is a natural product. Always ensure proper ventilation if using in enclosed spaces, though this board is manufactured to E1 low-formaldehyde emission standards.

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 areas
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.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
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.
