Norboard 1/2 x 2 x 2 OSB Handi-Panel

Oriented strand board, also known as OSB, is an engineered wood product formed by layering strands of wood in specific orientations. OSB panels have no internal gaps or voids and are ideal for construction and other uses. OSB panels are water resistant, although they do require additional membranes to achieve impermeability to water and are not recommended for exterior use.
