Hardie Board (Fiber Cement Siding)
Hardie Board is James Hardie's brand of fiber cement siding, manufactured from cement, sand, and cellulose fibers to create durable, fire-resistant, low-maintenance exterior cladding.
James Hardie fiber cement siding (commonly called Hardie Board) has become the premium choice for exterior cladding, offering exceptional durability and low maintenance. Composed of cement, sand, and cellulose fibers formed under high pressure, fiber cement resists rot, insects, fire, and moisture damage. It won't warp or crack like wood, fade like vinyl, or burn like traditional materials. Hardie Board comes in lap siding, vertical panels, shingles, and trim boards with various textures mimicking wood grain.
Why It Matters in Denver
Denver's climate and wildfire risks make fiber cement an excellent investment. The non-combustible material provides Class A fire rating—the highest available—crucial in Colorado's wildfire-prone areas. Hardie Board handles temperature extremes and intense UV exposure better than vinyl or wood, maintaining appearance for decades. The material carries a 30-year warranty and increases home resale value—buyers recognize quality when they see it. Professional installation with proper flashing and clearances from ground contact ensures maximum longevity.
