Roof Decking

OSB and plywood of the same thickness comply with the same performance standards. While the American Plywood Association (APA) makes no distinction between the two products, the proven performance of OSB makes it an attractive alterative to plywood at a much lower cost.

Why Is It Better?
OSB is easy to install and has many applications. LP’s OSB panels are manufactured to ensure consistency. They hold nails and fasteners securely, and come pre- marked with nailing lines to make installation faster. In addition, to wall sheathing, OSB is used for roof sheathing, floor sheathing and other specialty uses.

How is OSB made?
OSB is made by blending rectangular wood strands with thermal-set, waterproof adhesives. The treated strands are arranged in cross-directional layers that are then pressed together under extreme heat and pressure. The result is a rigid, dense engineered panel that is stiff, strong and durable.

Oriented strand board (OSB) sheathing is an innovative, affordable and environmentally smart wood-based structural panel for use in roof, wall and two- layer sub-floor systems. Since it was first commercialized on a large scale by LP more than 25 years ago, OSB has become the most popular structural panel in the U.S. Today, LP produces 6 billion feet of OSB annually—more than any other building products manufacturer in the world.Oriented strand board (OSB) sheathing is an innovative, affordable and environmentally smart wood-based structural panel for use in roof, wall and two- layer sub-floor systems.

Why is OSB so popular?
Because it meets the same performance standards as plywood, yet is more cost- effective. OSB has excellent moisture tolerance and is much less susceptible to the stress related problems of plywood, such as warping and ply separation. Made from wood chips and resins, it has exceptional dimensional stability and consistent quality because it’s not dependent on the character of an individual log. LP OSB is easy to install, with pre-marked nailing lines and a skid-resistant surface, providing good traction on pitched surfaces.

Environmentally Smart
OSB is also environmentally smart because it’s manufactured from a wide range of fast-growing and relatively small trees. The production process uses a maximum amount of wood fiber from each tree harvested, making better use of our forest resources.
