Really Smart Wood
Everyone knows LP® OSB as a cost-effective alternative engineered to meet the same performance standards as plywood. But it's things like our 25 years of experience, superior customer service and 20-year limited warranty that make LP OSB Sheathing the No. 1 selling sheathing in the world.

Get it done quicker and with less fuss. LP had the worksite in mind with touches such as a skid-resistant surface and pre-marked nail lines. Plus LP OSB comes in all the standard sizes you'd expect: from 4'x8' to 4'x10' and 3/8" to 7/8" thickness. Get LP OSB Sheathing specifications.

OSB meets the same performance standards as plywood, yet it won't cup or warp as easily. See how LP makes OSB.
OSB is efficient not just on the work site, but also in its manufacture: we use wood from small, fast growing trees. That means less waste and a better use of our forest resources.

About Faces
Since the pre-marked nail lines on OSB sheathing are on the rougher, textured side, you’ll probably want those facing outward. When framing walls, however, it makes no structural difference which side of the OSB faces in or out.
