Frequently asked questions
What is OSB3 and how does it differ from regular OSB or plywood?

OSB3 is a high-performance structural Oriented Strand Board designed for use in humid conditions. Unlike standard OSB (often OSB2), OSB3 is suitable for load-bearing applications in both dry and humid environments, such as roofing, flooring, and wall sheathing. It is a cost-effective alternative to softwood plywood, offering excellent strength and rigidity while being more affordable and sustainably produced.

What are the main uses for OSB3 boards?

9mm OSB3 is commonly used for:

  • Roof decking (flat and pitched roofs)
  • Wall sheathing
  • Flooring (especially as a subfloor)
  • General construction and renovation projects
    It performs reliably in a wide range of conditions and can be used in house building and structural applications.
Is this OSB board suitable for outdoor use?

Yes, OSB3 is suitable for humid conditions and temporary outdoor exposure. While it is not fully waterproof like exterior-grade plywood, it performs well in wet environments when properly sealed. For additional protection, we recommend applying a suitable sealer or covering the boards to prevent prolonged direct exposure to rain.
