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.

- BBA approved: Permits use in a wide range of commercial and domestic projects.
- Void-free construction: Consistent strength with no knots or core gaps.
