This OSB3 conditioned tongue & groove board is a rugged engineered wood panel sized at 2440mm by 1220mm with a thickness of 18mm. It is designed for structural use in indoor or semi-enclosed environments where occasional moisture or humidity is present. The “tongue & groove” (T&G) profile on its edges ensures boards can tightly interlock, which helps reduce movement, minimise squeaks, and create a flush surface. Use cases include flooring, roof decking, sub-floors, wall sheathing, and platforms.
