OSB (Oriented Strand Board) is an engineered wood-based panel consisting of strands of wood which are bonded together with a synthetic resin; the strands are pressed together in layers.
OSBâs performance continues long after the panel is put to use. The panels exhibit excellent fastener-holding capabil-. ity, even when nailed close to the panel edge. OSB resists deflection, delamination and warping because the wood and. adhesives work together to create a strong, dimensionally stable panel. OSB panels are made of real wood, a natural. insulator which provides excellent protection against heat loss and condensation. Many OSB panels are manufactured. in large dimensions, minimizing the number of joints that can âleakâ heat and admit airborne noise into the struc-. ture.
