Oriented Strand Board (OSB) that is conditioned for structural applications in dry, interior environments.

In comparison to Medium Density Fibreboard (MDF), Chipboard and other cost effective plywood alternatives, OSB sacrifices a smooth surface for enhanced mechanical performance by using longer strands of wood.

The trade term OSB/2 comes from the technical class denoted in BS EN 300 for ‘load-bearing boards for use in dry conditions’. Dry in this instance meaning environments where the boards are completely protected from external weather and are not exposed to wetting.

Typical Applications
  • Boarding up
  • Packaging
  • Furniture
  • Pallet tops
  • Signboards
  • Temporary formwork
Applicable Standards
  • BS EN 300 – OSB Definition, classification and specification
  • BS5268 – Structural use of timber

Hanson Plywood sources OSB/2 from FSC® Certified forest concessions from the UK and Republic of Ireland. The company’s robust Chain of Custody management system ensures that these certifications are respected and adhered to throughout the supply chain.
