OSB 3 Board 2440x1220x 9 mm Copy

Our OSB3 Boards are engineered for strength, stability, and durability in demanding construction environments. Each board is made from oriented wood strands bonded with wax and high-quality resin adhesives, providing superior structural integrity and moisture resistance.

Suitable for internal and external (protected) use, OSB3 is widely used in:

• Roofing and flooring systems
• Wall and roof sheathing
• Timber frame construction
• Site hoarding and packaging

At Wel Timber & Building Supplies, we’re proud to be a fully FSC® Certified company, committed to environmental responsibility. All our OSB3 boards are sourced from FSC® Certified forests, ensuring every sheet supports responsible forestry and sustainable building practices.

Manufactured to EN 300 standards, OSB3 offers consistent thickness, high load-bearing capacity, and an excellent surface for fixing or finishing.
