Louisiana-Pacific® Building Products

LP, or Louisiana-Pacific Corporation, began in 1972 with a goal to responsibly create a better structural panel out of a renewable natural resource. Their siding and structural solutions are both durable for homeowners and workable for the professionals who install it. McCoy’s Building Supply is proud to partner with LP whose dedication to creating sustainable products that are lighter, stronger, and easier to work with than traditional wood is unrivaled. LP WeatherLogic, LP SmartSide Trim and Siding and Legacy Sub-Flooring are available in-stock in select stores and with a two to three-week availability in all stores. Plus, first time purchasers of LP SmartSide, LP Structural Solutions including Legacy and WeatherLogic, and LP SmartSide Trim may be eligible for a rebate!

The Original and Best


Treated with an exclusive LP SmartGuard process, LP SmartSide Trim and Siding is formulated with zinc borate, adhesive resins, and water-resistant waxes. This means it’s engineered to withstand whatever nature throws at it. The ultra-durable LP SmartSide is available in either smooth or cedar textures. In fact, Louisiana-Pacific offers the ONLY smooth siding and trim in 16-foot lengths, resulting in faster installation and fewer seams. Both the smooth and textured versions of LP SmartSide are treated with SmartGuard which protects the product from termites and decay while allowing it to withstand humid coastal climates. Additionally, LP SmartSide brings impact resistance unmatched by vinyl or fiber cement siding, making it ideal for areas with wind or hail threats. In fact, it’s so tough it comes with a limited 50-year substrate warranty!

In addition to its strength, LP SmartSide is also known for being easy to work with and producing beautiful results. Its unique strand size and orientation make it less prone to breakage when being handled, easing frustrations and waste on the job. LP SmartSide Smooth captures the beauty and charm of “real wood” without knots, cracking or splitting and is pre-primed for excellent paint adhesion. Their cedar textured siding gives homeowners the look of real cedar siding with less maintenance and game-changing strength.
