LP SmartSide siding and trim are engineered wood products for finishing the outside of a new home or remodel. Lap siding, panels and shakes give you choices for the walls, with trim, fascia and soffit to finish the exterior. You can plan the wall treatment and finishing details together.
LP Building Solutions is Louisiana-Pacific Corporation, based in Nashville, Tennessee. Founded in 1972, the company is publicly traded on the New York Stock Exchange under LPX. LP pioneered the commercialization of oriented strand board.
Choose the siding and trim together
Lap siding gives you horizontal courses, panels give you larger wall sections, and shakes give you a smaller repeating pattern. Choose the main wall treatment first, then decide whether the gables need a different look. Plan the transitions before you start cutting.
Trim deserves attention early. Its width changes how a window looks, and its placement determines where siding courses and cuts land. SmartSide includes trim, fascia and soffit, so the roof edge belongs in that planning too. Settle the window trim and corner details before laying out the siding.
LP uses waxes, resins and zinc borate in its SmartSide engineered wood siding. Water still needs a planned route around openings and intersections. Handle the flashing details at windows, doors and roof intersections before covering them.
Plan the color and finish work
LP offers primed siding in a brushed smooth texture, while SmartSide ExpertFinish siding comes in 16 curated colors. Primed siding puts finish painting into your job plan. Settle the wall and trim colors together.
Cut edges and touch-ups belong in the installation plan. Reaching an exposed edge gets harder once the next piece covers it. Have the specified finishing materials ready and treat cut edges according to the product instructions as the work progresses.
LP also covers structural work
LP Structural Solutions includes FlameBlock fire-rated sheathing, BurnGuard fire-retardant-treated OSB, WeatherLogic air and water barrier, TechShield radiant barrier sheathing, and Legacy and TopNotch subflooring.
Installation affects coverage
A straight-looking wall can still have poor water details. For siding panels, work out the layout, support, flashing, fastening and joints before hanging them. LP provides installation guides and how-to videos. Use the instructions for the exact product, with window and door details resolved before the first panel goes up.
For long service, keep the finish maintained and pay attention to joints and places where water collects. LP’s warranty excludes damage resulting from incorrect installation. Follow the specified flashing, joint and cut-edge details.
LP’s replacement warranty provisions include five years of 100% labor and material replacement coverage and a 50-year prorated material replacement feature. Account for your share of a later replacement: after the first five years, the material replacement feature covers a portion of the material cost.

Frequently Asked Questions
What is LP siding?
LP SmartSide is engineered wood siding made with wood, waxes, resins and zinc borate. The siding comes in lap, panel and shake profiles. You’re getting an engineered wood product rather than boards cut from solid lumber.
Is LP SmartSide siding good?
LP SmartSide is a good fit if you want engineered wood siding with several exterior profiles to choose from. The finished wall still depends on the details you can’t see once it’s covered, especially flashing and drainage. A well-finished face won’t make up for water getting trapped behind it.
How long does LP siding last?
Installation, moisture exposure and finish maintenance all affect how long LP siding lasts. The 50-year prorated material replacement feature isn’t a promise of 50 years of service. You get a better measure of the wall’s condition by checking the finish and water-prone details than by counting years alone.
How do you install LP SmartSide siding panels?
Start with the instructions for the exact LP SmartSide panel you’re using, since fastening and joint details need to match the product. Before hanging panels, work out your layout and resolve support and flashing details. Keep the instructions handy as you work so fastening, joints and cut-edge treatment get checked before the next panel covers anything.
