Oriented Strand Board (OSB) is an engineered wood product formed by layering strands of wood in specific orientations. OSB offers excellent workability as it is easy to saw and drill, paint, stain, glue and fasten. Traditionally a strong colour with mixed timbers, OSB can also be powder coated. As part of our DesignerPly range OSB can have the same colours and finishes. Containing recyclable material, OSB is available PEFC certified.
