Beauty of Engineered Wood Siding

The beautiful contrast of these exterior claddings creates architectural balance that’s visually appealing and welcoming.

  • Rich cedar grain texture or smooth finish
  • Longer lengths may reduce seams
  • Unmatched consistency for curb appeal


LP SmartSide Trim & Siding is treated to the core with LP’s proprietary SmartGuard® process, making it one of the most durable siding solutions available on the market today.

  • LP lap siding resists hail and impact damage better than fiber cement and vinyl siding
  • Stands up to harsh weather in any climate
  • Resists damage from termites and fungal decay


LP SmartSide treated engineered wood siding cuts out the time you spend dealing with warped and split pieces when properly stored and applied. Virtually every piece leaves the mill straight and ready to use.

  • Works and cuts like traditional wood
  • Requires fewer tools than fiber cement products
  • Weighs less, easier to carry, less breakage than fiber cement
  • Longer lengths may mean fewer seams and less waste when compared to fiber cement
