Unbranded Oriented Strand Board (Common: 7/16 in. x 2 ft. x 4 ft.; Actual: 0.435 in. x 23.75 in. x 47.75 in.)

Oriented Strand Board (OSB) is an engineered wood product manufactured from rectangular wood strands oriented in a cross-layered pattern and waterproof, heat-cured adhesives. This lightweight panel is easy to use and install and shares many of the same performance characteristics as plywood at a much more affordable price. Features include resistance to deflection, delamination and warping, making OSB ideal for small flooring, wall and roof repairs. OSB panels are even tough enough to resist distortion when faced with forceful wind and seismic conditions. Great for home décor projects too! California residents: See Proposition 65
