OSB, or Oriented Strand Board, is an engineered wood product made from layers of rectangular wood strands compressed with adhesives under heat and pressure. It is commonly used for structural applications like wall and roof sheathing, sub-flooring, and in furniture production. The strands are oriented in different directions in each layer, giving the final product consistent strength, durability, and fewer voids than traditional plywood.
