OSB Sheathing

Oriented Strand Board - is manufactured from waterproof heat-cured adhesives and rectangularly shaped wood strands that are arranged in cross-oriented layers, similar to plywood. This results in a structural engineered wood panel that shares many of the strength and performance characteristics of plywood. Produced in huge, continuous mats, OSB is a solid panel product of consistent quality with no laps, gaps or voids.

Oriented Strand Board (OSB) is used to sheath lumber joists. The joists are supported by lumber headers. Builders may use bridging to maintain floor joist spacing.

Walls are typically framed with double top-plates. Piping and wiring penetrate the double-top plate.

OSB is stored off the ground on the job site.
