Built to take a hit

Colorado weather doesn't stand a chance

Hail striking LP SmartSide siding on a home exterior
The myth

Engineered wood will crack when impacted by hail.

The truth

Built to withstand everyday impacts and hail up to the size of a golf ball, LP SmartSide siding and trim delivers lasting durability and curb appeal.

Protect your home against damage from hail

LP SmartSide is engineered to be exceptionally durable, to reduce hail damage and maintain its appearance after impact, saving on costly repairs. That's why builders, contractors, and homeowners in demanding climates rely on LP SmartSide.

How does LP SmartSide siding protect against hail?

LP SmartSide is a strong choice for hail-resistant siding thanks to its proprietary SmartGuard® manufacturing process. Every strand of wood is treated with a carefully formulated mix of resins, waxes, and zinc borate, then finished with an overlay to protect against tough weather elements.

Proven to perform against hail

In third-party testing commissioned by LP Building Solutions, LP SmartSide lap siding resisted hail damage better than comparable fiber cement or vinyl siding.
