LP siding and structural panels cover exterior siding and trim, sheathing and subflooring for builders and homeowners. SmartSide handles the finished exterior, and Structural Solutions gives you dedicated lines for the layers underneath. You can plan each part of the job within LP’s engineered wood range.
Louisiana-Pacific Corporation uses the name LP Building Solutions. The company is based in Nashville, Tennessee, and develops engineered wood products for residential and light commercial construction. Its range includes OSB, and it introduced SmartSide Trim & Siding in 1997.
SmartSide for the finished exterior
SmartSide includes lap, panel and shakes, along with trim, fascia and soffit. Lap gives you horizontal courses, panels give you larger sections to lay out, and shakes change the pattern on an accent area. Plan the trim with the siding. Settle how the courses and panel joints meet your windows, corners and roof edges before installation starts.
SmartSide ExpertFinish comes in 16 curated colors. For a painted exterior with a quieter surface pattern, SmartSide primed siding includes a brushed smooth texture. Judge your color and texture beside the roof, windows and masonry you’re keeping.
On an older house, the historical premature-deterioration complaints concerned Inner-Seal siding. Identify the installed siding before planning a repair.
Sheathing and subflooring for the rest of the job
LP also offers sheathing and subflooring through Structural Solutions. FlameBlock serves fire-rated sheathing applications, WeatherLogic provides an air and water barrier line, and TechShield is radiant barrier sheathing. Legacy and TopNotch cover subflooring. That gives you a separate product family to work from for the structural panels beneath the finished surfaces.
FlameBlock comes in one-sided and two-sided variants, while BurnGuard is LP’s fire-retardant-treated OSB line. Match the panel and its sidedness to the assembly specified in your plans.
For the floor, choose the subfloor panel with the framing and finished flooring requirements in hand. LP identifies Legacy as its premium subflooring line and includes TopNotch in its subflooring range. Match the panel specification to the whole floor assembly.

Frequently Asked Questions
What is LP SmartSide siding made of?
LP SmartSide is engineered wood siding that incorporates waxes, resins and zinc borate. You still need good flashing and joint details, because siding is only one part of keeping water out of a wall.
Does LP SmartSide come in panel siding?
Yes, LP SmartSide includes panel siding. Your layout matters: the panel joints determine where seams fall, and planning around openings helps avoid awkward narrow pieces beside windows and doors.
What colors does LP siding come in?
LP SmartSide ExpertFinish comes in 16 curated colors. If you’re matching an existing exterior, a physical sample beside your roof and trim tells you more than a color on a screen.
Is LP Inner-Seal siding the same as SmartSide?
No. LP Inner-Seal is an older siding line associated with complaints of premature deterioration. SmartSide was introduced in 1997. If you’re repairing an older wall, identifying the existing siding comes before matching its appearance.
What is LP OSB used for?
LP OSB includes sheathing, which forms part of the building beneath the finished surfaces. You need the panel thickness and span rating specified for your framing; the material name alone isn’t a complete panel specification.
