This Sterling Board conforms to OSB 3 standards, indicating its suitability for structural applications in humid conditions. It meets or exceeds the requirements for strength, stiffness, and durability, ensuring reliable performance in demanding environments.

15mm OSB Board - Moisture Resistance
Unlike MDF and other interior laminate sheet materials, 15mm OSB is able to hold its own in humid environments, making it ideal for house building.
While the OSB2 board is only suitable for dry conditions, OSB3 board can withstand more challenging conditions. While the boards are moisture resistant, this does not mean that the boards are completely waterproof.
As a rule of thumb we always suggest adding further weather protection if you plan to use it for permanent outdoor use.
You can do this by adding weather-proof exterior paint. Follow the exterior paint with a wood waterproofing sealant and allow 12-14 hours for it to dry before installing it - you can add a second coat if required.
