SmartSide™ Trim and Fascia offer consumers superior product-performance and aesthetic appeal. Specifically developed to coordinate with the SmartSide family of treated engineered wood siding, SmartSide products can also serve as stand-alone replacements for solid wood or other trim materials for all alternative exterior-cladding products. SmartSide Trim and Fascia products are manufactured using the borate-based SmartGuard™ process to resist termites and fungal decay.
