LP® 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. OSB 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.
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. It even comes with a transferable 20 year limited warranty.
LP® OSB Flooring Top Notch® family consists of three grades: our standard LP OSB
TopNotch, LP OSB TopNotch Orange Plus, and LP OSB TopNotch High Performance.
