This unsanded OSB board is a versatile construction panel designed for projects where a raw, structural surface is needed. Measuring 2500 by 1250 mm with a thickness of 6 mm, it provides a lightweight yet stable base that is easy to handle and cut to size during installation. Because the surface is not sanded, it maintains a natural texture that allows adhesives and coatings to bond more effectively. This makes it a practical choice for underlayment, temporary partitioning, or internal cladding for those who plan to cover the boards with another finishing material.
