Product Overview
Structural OSB 3 Sterling board, measuring 2397mm x 1197mm (8' x 4') with a 9mm 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 sheathing, panelling, and internal construction.
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 2397mm x 1197mm: Designed to suit UK construction modules (based on 600mm and 400mm centres), reducing cutting and waste.
- Thickness 9mm: Lightweight panel suited to sheathing, soffits, and panelling.
Please Note: Colour and finish are representative only and may vary slightly as this is a natural product.

- Roof decking (sarking): Forms a solid deck beneath membranes.
- Light flooring and underlayment: Suitable for domestic floors with close joist centres.

- Sheds and garden buildings: Panels for walls, floors, and roofs.
- Shopfitting and displays: Useful for racking, stands, and panelling.
- General domestic use: Shelving, craft projects, and utility joinery.
Installation Guidance
- Seal cut edges when exposed: Prevents moisture ingress.
- Use correct fixings: Galvanised or stainless fasteners recommended.
- Fix to 600mm or 400mm centres: Ensures stable support and correct edge alignment.
