You want your exterior siding to last … and last, and last – regardless of the climate you live in. That’s why all LP® SmartSide® Trim & Siding products are engineered using our proprietary SmartGuard® manufacturing process. The process begins with quality wood strands or wood fibers.
Next, every inch of every LP SmartSide product is treated to the core with an advanced formula of waxes, adhesive resins and zinc borate applied before being bonded with a resin-saturated, water-resistant overlay. This process helps the products resist termites and fungal decay, for long-term strength and durability in a variety of weather conditions.
Extreme Protection in Tough Climates

Exterior trim and siding are subjected to many weather conditions and termites. The SmartGuard process offers four elements of protection against these damaging forces.
Zinc borate. Engineered wood products treated with zinc borate have been proven to effectively resist damage from termites and fungal decay for decades. This safe, naturally-derived additive provides long-lasting performance to help preserve LP SmartSide trim and siding.
Adhesive resins. LP SmartSide products have incredible resistance to impacts from hail, thanks in part to industrial-grade adhesive resins.
Waxes. Special water-resistant waxes coat each strand or fiber of wood for enhanced durability in rainy, humid environments.
Resin-saturated overlay. Offering the final layer of protection against the elements, a resin-saturated overlay resists excessive moisture intrusion while providing a durable base for quality paint adhesion and beauty.
Real-World Testing
How can you know that the SmartGuard process truly provides long-lasting protection? The durability of LP SmartSide treated engineered wood products has been tested in the tropical climate of Hilo, Hawaii, where nearly 170 inches of rain falls annually and termite colonies thrive. Samples of the material were left in this brutal environment at a reputable third-party testing site for more than 20 years. Even after all those years of exposure, LP SmartSide products remained structurally sound.
