LP SmartSide Engineered Wood Siding in the Chicago Suburbs
LP SmartSide engineered wood siding gives Chicago-area property owners the dimensional warmth of wood without the maintenance demands that make natural wood impractical in the Midwest.
What LP SmartSide Is
LP SmartSide is not solid wood and it is not vinyl. It is an engineered wood composite manufactured from wood strands that are treated with LP's SmartGuard process, a borate-based treatment that is integrated into the wood fiber itself before compression, not applied as a surface coating. The result is a panel that resists fungal decay, termite damage, and moisture infiltration at the material level, not just at the surface.
The product is then finished with a resin-saturated overlay and factory primer, giving it a surface ready for field painting in a wide range of colors. The final appearance closely mimics painted wood lap siding, board-and-batten, cedar shakes, or trim profiles depending on the product line selected.
LP SmartSide vs. Natural Wood
Natural wood siding requires painting or staining every 5 to 7 years in the Chicago climate. It is susceptible to rot at joints, penetrations, and areas where finish has worn away. Moisture infiltration in a freeze-thaw cycle can cause significant damage to wood substrates in a single winter. Insects, particularly carpenter ants and termites, treat untreated wood as a resource.
- SmartGuard treatment provides resistance to fungal decay and insects
- Engineered composite does not absorb moisture like solid lumber
- Factory finish system holds field paint longer than raw or site-primed wood
- Repaint cycle extends to 8 to 12 years versus 5 to 7 for solid wood
LP SmartSide vs. Vinyl
The comparison most homeowners are evaluating is LP SmartSide versus premium vinyl. Vinyl requires no painting and has a longer maintenance-free period, but it looks like vinyl. The surface sheen and panel flex are visible cues that read as different from wood. LP SmartSide has the dimensional depth, texture, and shadow lines of wood siding.
For homes in neighborhoods where vinyl is aesthetically out of place, or for homeowners who want a painted-wood appearance without the maintenance burden of solid wood, LP SmartSide is the direct answer. LP SmartSide is also more impact-resistant than standard vinyl and holds fasteners more securely, which matters in the wind-driven conditions of the Chicago suburbs.
Installation Requirements for Warranty Compliance
LP SmartSide's warranty is contingent on installation compliance. That means: proper clearances above grade and above rooflines, full-perimeter back-priming on field-cut ends, appropriate flashing at all horizontal transitions and penetrations, and field painting within 180 days of installation. Missing any of these steps does not just void the warranty. It introduces the moisture pathways and UV exposure that cause premature failure.
Americanstruction installs LP SmartSide in full compliance with LP's published installation guidelines. Every field cut is back-primed. Clearances are maintained. Flashing is installed at every required location. The product performs as rated when installed as specified.
Frequently Asked Questions
LP SmartSide is an engineered wood siding product manufactured by Louisiana-Pacific. It is made from wood strands treated with LP's SmartGuard borate-based process, which provides resistance to moisture, fungal decay, and insects. It is available in lap, vertical, soffit, and trim profiles and is designed to replicate the appearance of painted wood siding with reduced maintenance requirements.
LP SmartSide provides a more realistic wood appearance with deeper texture, shadow lines, and dimensional character that vinyl cannot match. It requires painting, which vinyl does not. Vinyl requires no maintenance but reads visually as a manufactured product. LP SmartSide is more impact-resistant than standard vinyl. The right choice depends on the property's aesthetic requirements and the owner's maintenance preferences.
LP SmartSide carries a 50-year limited warranty against fungal decay and termite damage when installed per manufacturer guidelines. Structural performance over that period depends on proper installation, maintaining painted finish, and sealing field cuts. Correctly installed and maintained, the product is expected to outperform the building it covers.
Yes. LP SmartSide is delivered with a factory primer and requires field painting within 180 days of installation. It is not a paint-free product. The upside is that it holds paint longer than solid wood, typically 8 to 12 years between repaints depending on exposure and paint quality, and accepts any exterior latex or oil-based topcoat.
