Prevention Against Damage

LP SmartSide siding is a more durable material than James Hardie boards because of its proprietary SmartGuard® manufacturing process. This process ensures that every strand of wood is treated with a carefully formulated mix of resins, waxes, and zinc borate, and finished with an overlay to offer complete protection against extreme heat, moisture, termites, and fungal decay.

This naturally derived additive helps engineered wood resist damage from termites and fungal decay.
Engineered wood stands up to impact and survives freeze/thaw cycles due to resins that offer incredible strength.
Designed to resist moisture, waxes coat each strand to offer enhanced durability in humid environments.
This final element of protection resists moisture intrusion, providing a durable base for a finished look.
