Oriented Strand Board

ORIENTED STRAND BOARD (OSB) OSB is a performance-rated structural panel engineered for uniformity, strength, versatility, and workability. It is made of strands, flakes or wafers sliced from small diameter, round wood logs and bounded with an exterior-type binder under heat and pressure. It is utilized internationally in a wide array of applications including commercial and residential construction and renovation, packaging, furniture, shelving and do-it-yourself projects. Because it is engineered, OSB can be manufactured to meet specific requirements in thickness, density, panel size, surface texture, strength, and rigidity. This engineering process makes OSB the most widely accepted and preferred structural panel among architects and contractors.
