An engineered wood panel made of compressed wood strands used for wall and roof sheathing.

Definition

Oriented strand board (OSB) is a structural panel manufactured by compressing and gluing wood strands in specific orientations to achieve structural properties similar to plywood. It is widely used for wall sheathing, roof decking, and floor underlayment in wood-frame construction. OSB is generally less expensive than plywood and is manufactured from fast-growing, sustainably managed species.
