What Is an OSB Floor?
An OSB floor is a layer of a flooring system that’s known as subfloor. Subfloor is the structure that lies beneath the visible floor, which could be hardwood, vinyl, carpet, or another material. OSB, or oriented strand board, is an engineered structural panel made from compressed strands of wood arranged in perpendicular layers. OSB is different from other types of wood panels because its pieces of wood are “oriented,” and placed deliberately, not at random. An OSB floor is an environmentally friendly flooring platform valued for its uniformity, strength, and versatility.
