A product made from wood strands arranged in layers and bonded with resin, OSB serves many uses including roof decking, sidewall sheathing and floor underlayment. A cost-effective, high-performance structural panel, LP OSB has been in use for more than three decades and is known for its uniformity, strength, density and workability.

LP® FlameBlock® Fire-Rated OSB Sheathing offers you the best of both worlds—impressive structural strength and remarkable burn-through fire resistance. Created by applying a patented, non-combustible Pyrotite® coating to LP® OSB panels, LP FlameBlock Sheathing is an ICC certified (ESR-1365), structural fire-rated sheathing with a Class A Flame Spread Rating.

LP® LongLength™ OSB Sheathing is a line of extended length OSB panels engineered specifically for wall applications. Designed for vertical installation, LP LongLength Sheathing can lower building costs, increase wall strength, and help meet code requirements in wind and seismic zones.

LP® TopNotch® Sub-Flooring is made with LP OSB, so it’s uniform, flat and rigid, with no core voids or knots.

LP® TechShield® is made by laminating a thin, durable sheet of aluminum to our LP OSB Sheathing. After the foil lamination process takes place, the panel is incised, resulting in small holes called VaporVents™, that penetrate the foil, glue and OSB substrate. This patented incising process, makes LP TechShield different from other radiant barrier products.
