Stop Fungal Decay Before It Starts
To create durable siding, every fiber and strand of LP® SmartSide® Trim & Siding is fortified throughout the material with our proprietary SmartGuard® process to resist termites and fungal decay. SmartGuard halts the decay cycle. LP SmartSide stands up to some of the world's harshest climates with virtually no decay.
LP SmartSide has all the benefits of traditional wood with none of the drawbacks. Cuts with traditional carpentry tools. Weighs less than fiber cement, won’t shatter and installs faster. Learn about how we engineered to get the most out of wood.

Withstand the Worst
Siding protected with SmartGuard resists fungal decay. 
Since 1996, we’ve put our siding through brutally wet testing in Hilo, Hawaii. With more than 170 inches of annual rainfall and exposure to Formosan termite colonies, it remains structurally sound. Take a visit to the SmartGuard testing grounds.
There aren’t many special needs for our siding, but if you’re interested in power-washing or repainting LP SmartSide, take a look through our care and maintenance information.
