A nonveneered wood panel product commonly used for sheathing and as subflooring, made by bonding three or five layers of long, thin wood strands under heat and pressure using a waterproof adhesive. The surface strands are aligned parallel to the long axis of the panel, making the panel stronger along its length. Abbr: OSB. (Ching, 1995)
