LP SmartSide Engineered Wood Siding

LP SmartSide brings the natural warmth and workability of real wood to an engineered product treated with SmartGuard process technology that provides built-in protection against moisture, fungal decay, and termite damage. For Chicago homeowners who want authentic wood grain texture and the ability to receive custom stain finishes, LP SmartSide delivers what fiber cement and vinyl cannot: a genuine wood appearance that feels like wood when you run your hand across it, because it is wood, just smarter.

The SmartGuard treatment process infuses zinc borate throughout the oriented strand board substrate, providing protection not just at the surface but through the entire cross-section of the product. This is a meaningful advantage over surface-treated products, because any cut, nail hole, or field modification exposes fresh material that remains protected. In Chicago, where driving rain can find its way into the smallest unsealed gap, through-and-through treatment provides a critical safety net against moisture intrusion.

Cornerstone Roofing Co. is an LP SmartSide certified installer, and our crews appreciate the product's ease of handling on the job site. SmartSide weighs roughly half as much as fiber cement, which means faster installation, less fatigue-related quality issues late in the day, and lower labor costs passed on to the homeowner. The product cuts cleanly with standard carpentry tools without the silica dust hazard that fiber cement generates, creating a healthier work environment for our installers and your family.

LP SmartSide carries a 5/50 year limited warranty, with the first five years covering 100% of material and labor costs. Impact resistance testing shows SmartSide outperforms fiber cement in hail and debris impact scenarios, flexing rather than cracking under force. Wind resistance meets or exceeds code requirements for all Chicagoland wind zones. The primary durability consideration is finish maintenance: the factory-primed product requires painting within 60 days of installation, and the finish should be recoated every 10-15 years to maintain protection.
