Why Choose Hardie® Trim Boards?

Add beautiful finishing touches that are built to last.

Hardie® siding is noncombustible—it will not burn.** It resists damage from moisture and holds no appeal for pests like woodpeckers or termites.

Our fiber cement siding and trim products are formulated to offer superior performance based on your region's unique climate needs, and help protect against damage from weather extremes, hurricanes, winter storms and more.

Enjoy a low-maintenance exterior with a 30-year non-prorated limited, transferrable substrate warranty for lasting peace of mind and quality you can trust.

Create unmatched curb appeal

ColorPlus® Technology finishes provide countless color options in an ultra-durable finish. Our factory-applied, baked-on color is cured between coats for superior color consistency, adhesion and durability.
