LP makes two product lines that matter: SmartSide engineered wood siding and Legacy Premium sub-flooring. Both solve real jobsite problems with proprietary technology that competitors haven’t matched.
SmartSide: The Siding That Works Like Wood But Doesn’t Act Like It
SmartSide features SmartGuard treatment that resists termites, decay, and weather damage. The products resist impact, freeze-thaw cycles, fungal decay, and moisture. They cut and install like traditional wood.
The lengths tell the efficiency story. Lengths ranging from 16 to 20 feet mean fewer seams on big Montana custom homes. Fiber cement tops out at 12 feet. Those extra 4-8 feet per board add up fast on a 3,000 square foot siding job.
Pre-primed for optimal paint adhesion with realistic woodgrain textures. The 5/50 year limited warranty beats most fiber cement options and includes hail damage coverage. That hail coverage matters in Montana where summer storms pound the Flathead Valley every July.
| SmartSide Specifications | Value |
|---|---|
| Length Options | 16-20 feet |
| Treatment | SmartGuard with zinc borate |
| Warranty | 5/50 year limited |
| Hail Coverage | Included |
| Installation | Cuts like traditional wood |
| Weight vs Fiber Cement | Lighter |
The weight difference changes everything on second-story applications. Crews move faster when they’re not wrestling heavy fiber cement boards up scaffolding.
Legacy Premium Sub-Flooring: Gorilla Glue Changes the OSB Game
LP Legacy Premium Sub-Flooring features strand-based composite construction with industry-leading stiffness verified by APA testing. Its unique Gorilla Glue Technology coating enhances moisture resistance and bonding strength, complemented by high-performance edge seals and rain drainage notches.
That Gorilla Glue coating isn’t marketing fluff. Standard OSB swells when wet during framing. Legacy’s coating protects against the moisture that’s inevitable when you’re framing through Montana’s spring rains.
The product includes a no-sand, lifetime limited warranty. No sanding means no callbacks to fix squeaky floors or proud edges where moisture caused swelling.
| Legacy Sub-Flooring Specifications | Value |
|---|---|
| Construction | Strand-based composite |
| Moisture Protection | Gorilla Glue Technology coating |
| Edge Protection | High-performance seals |
| Drainage | Rain drainage notches |
| Stiffness Rating | APA-verified exceptional |
| Warranty | No-sand lifetime limited |
What Sets LP Apart
LP focuses exclusively on engineered wood products with proprietary SmartGuard treatment technology. They pioneered OSB in North America and maintain market leadership as the world’s largest OSB producer by scale.
Their products are carbon-negative, providing an environmental advantage. The company achieves this through proprietary wood science and resin-binder chemistry that maximizes yield from every log.
LP’s strategy centers on branded systems rather than commodity products, moving from basic OSB to high-performance integrated systems like LP WeatherLogic. This approach provides resilience against the commodity price swings that plague basic OSB manufacturers.
The safety record speaks to operational excellence: achieving 1 million incident-free hours 18 times. That’s the kind of consistency that translates to product quality.
The Bottom Line on LP
LP earned its reputation by solving the two biggest exterior problems in construction: siding that acts like wood when you don’t want it to, and subflooring that fails when it gets wet. SmartSide gives you wood’s workability without wood’s weaknesses. Legacy gives you OSB’s cost advantage without OSB’s moisture problems.
Both product lines reflect LP’s focus on engineered solutions that perform better than traditional materials. The 50-year siding warranty and lifetime subflooring warranty back up the performance claims. For Montana contractors dealing with freeze-thaw cycles, spring moisture, and summer hail, these aren’t luxury upgrades — they’re insurance against callbacks.
Frequently Asked Questions
Q: What warranty does LP SmartSide siding offer?
LP SmartSide comes with a 5/50 year limited warranty that includes hail damage coverage. This warranty exceeds most fiber cement options and provides protection against Montana’s summer hailstorms.
Q: How long are LP SmartSide siding boards compared to fiber cement?
LP SmartSide siding comes in lengths ranging from 16 to 20 feet, while fiber cement typically maxes out at 12 feet. Those extra 4-8 feet per board mean fewer seams and faster installation on large siding projects.
Q: What makes LP Legacy subflooring different from standard OSB?
LP Legacy Premium Sub-Flooring features Gorilla Glue Technology coating that enhances moisture resistance and bonding strength, plus high-performance edge seals and rain drainage notches. The product includes a no-sand, lifetime limited warranty, eliminating callbacks for squeaky floors or swollen edges.
Q: Is LP SmartSide easier to install than fiber cement siding?
LP SmartSide cuts and installs like traditional wood while weighing less than fiber cement, making it faster to handle on scaffolding. The pre-primed surface with realistic woodgrain textures is ready for optimal paint adhesion right out of the box.
Q: What pest and weather resistance does LP SmartSide provide?
LP SmartSide features proprietary SmartGuard treatment with zinc borate that resists termites, decay, and weather damage. The product withstands impact, freeze-thaw cycles, fungal decay, and moisture damage better than traditional wood siding.
Q: Does LP make anything besides SmartSide siding and Legacy subflooring?
LP focuses exclusively on engineered wood products and is the world’s largest OSB producer by scale. Beyond SmartSide and Legacy, they produce LP WeatherLogic integrated weatherization systems and maintain their position as the pioneer of OSB in North America.
