LP® SmartSide® Trim & Siding products deliver the beautiful, authentic look of real wood. But they offer multiple advantages over traditional wood trim and siding materials. They’re free of knots so you don’t waste time sorting through flawed pieces. And unlike traditional wood, LP SmartSide Trim & Siding products resist cupping and warping. They’re factory pre-primed to take paint well, delivering optimal adhesion and consistent application. And our proprietary SmartGuard® manufacturing process helps protect against termite damage and fungal decay. Here’s some more smart protection: our 5/50 Year Transferable Limited Warranty provides a 5-year, 100% labor and replacement feature and a 5/50 Year Prorated Limited Warranty on the product. The difference is clear. LP SmartSide products are the smart choice.
