OSB boards, short for oriented strand boards, are an engineered wood item used in construction. In terms of manufacture, These are akin to the two plywood and chipboard. They're manufactured from sheets of timber strands, that should be placed on best of one another at 90-degree rotations in the course of the manufacturing system, and can then be connected to each other with adhesives, just before staying bonded with heat and force.
