Quick Answer

LP SmartSide engineered wood siding costs $7–$11 per sq ft installed in Wisconsin and lasts 25-40 years. It uses treated wood strands with a SmartGuard process that resists fungal decay, termites, and moisture. It offers a natural wood aesthetic at lower cost than fiber cement but requires repainting every 8-12 years.

LP SmartSide: How Engineered Wood Works

Engineered wood siding is not plywood or OSB — it's a specifically engineered product:

  • Wood strand substrate — Oriented wood strands bonded with resin under high heat and pressure
  • SmartGuard process — Zinc borate treatment penetrates the entire panel for fungal decay and termite resistance
  • Overlay — Engineered resin overlay on the face for moisture resistance and paint adhesion
  • Deep wood grain texture — Realistic cedar texture that vinyl and fiber cement can't match

Wisconsin-Specific Considerations

  • Moisture management is critical — Despite treatment, engineered wood needs proper installation with housewrap and flashing. Wisconsin's driving rain and snowmelt mean zero tolerance for installation shortcuts.
  • Paint maintenance required — Unlike ColorPlus fiber cement, LP SmartSide needs repainting every 8-12 years. In Wisconsin's UV and weather, plan for the shorter end of that range.
  • Excellent impact resistance — The wood strand construction absorbs impact better than any competitor. Hail, baseballs, and tree branches rarely cause visible damage.
  • Installation weather window — Best installed when temps are above 40°F and dry. Similar to fiber cement in this regard.
Our Recommendation: LP SmartSide is an excellent choice when you want the warmth and character of real wood at a lower cost than fiber cement. It's particularly popular for craftsman-style, farmhouse, and cottage-style homes in Waukesha and Milwaukee counties.

Frequently Asked Questions

LP SmartSide is treated with the SmartGuard process specifically to resist rot. However, installation quality is everything. Cut edges must be sealed, flashing must be installed correctly, and caulking must be maintained. With proper installation and maintenance, rot is not a concern.

Very well. The wood strand construction handles freeze-thaw better than solid wood and doesn't become brittle in cold like vinyl. It's dimensionally stable across temperature extremes. Our main caution is ensuring paint integrity is maintained to prevent moisture infiltration.
