Osb 4 X 8

Oriented strand board (OSB) and plywood are wood structural panels made by compressing and gluing pieces of wood together. While OSB and plywood appear similar and are generally interchangeable, the different ways that each material is manufactured contribute to each having its unique strengths and weaknesses.

Oriented Strand Board (OSB) is a widely used, versatile structural wood panel. Manufactured from water-resistant, heat-cured adhesives and rectangular-shaped wood strands that are arranged in cross-oriented layers, OSB is an engineered wood panel that shares many of the strength and performance characteristics of plywood. OSB's combination of wood and adhesives creates a strong, dimensionally stable panel that resists deflection, delamination, and warping; likewise, panels resist racking and shape distortion when subjected to demanding industrial applications. Relative to their strength, OSB panels are light in weight and easy to handle and machine.
