More about Oriented Strand Board

Oriented Strand Board (OSB) is a structural wood panel product typically used for sheathing (roof, wall and floor), I-joists and rim boards. OSB is manufactured by debarking and cutting wood logs into strands, which are then dried and arranged in layers of alternating orientation. The strands are then glued together with waterproof adhesives, typically a combination of phenol formaldehyde and polymeric methylene diphenyl isocyanate, and cured under heat and pressure. Panels are typically constricted in three layers with the central layer oriented at a 90 degree angle to outer layers. Panels are dried and treated with a sealant along the edges for moisture resistance.
