For quality; subjected to a continuous quality control process, from forest to finish. Rigorous testing helps assure that each product meets the highest standards of quality. Advanced baked-on finish consists of five coats of baked-on paint, and a sealer providing increased resistance to cracking, splitting, warping, splintering and buckling of the substrate. Subjected to outdoor testing in seven different climates throughout North America. It has been shown to withstand the intense cold of the Canadian north, tropical humidity of Florida, scorching heat of Arizona, the salty air of the seacoast and the winds sweeping the prairies.

LP® TechShield® Radiant Barrier Sheathing helps block radiant heat from entering the attic. The result: LP TechShield can reduce monthly air conditioning costs up to 17%. It installs just like regular roof sheathing, with no additional labor costs. And unlike other radiant barriers, LP TechShield features VaporVents™ technology, which helps the panel dry quickly if it’s exposed to moisture during the construction process. We’ve been making LP TechShield for more than a decade. It was the first radiant barrier panel on the market and is still the brand that builders use and prefer the most.

LP Building Products pioneered oriented strand technology more than 35 years ago, and our leadership in the OSB category continues today. It’s no surprise that LP makes the world’s best-selling OSB sheathing. A cost-effective, high-performance structural panel, LP OSB is known for its uniformity, strength, density and workability.

LP® SolidStart® LVL is remarkably strong, straight, and consistent. It is an excellent choice for most load-bearing applications and offers several advantages over traditional lumber. Because of its consistency, you are able to reduce waste, save on material costs, and ultimately save time on the job site. LP SolidStart LVL is backed by our Lifetime Limited Warranty.
