Homeowners often ask us, “What is fiber cement and how is it made?” In simple terms, fiber cement siding is a durable, high-performance exterior material crafted from a precise mix of cement, sand, water, and cellulose fibers. This combination creates a solid, dimensionally stable product that stands strong against moisture, temperature swings, and impact.

Unlike vinyl or wood, fiber cement doesn’t warp, rot, or attract pests. It delivers the classic look of natural materials, such as wood or stucco, without the constant upkeep. For Colorado homeowners facing intense sun, snow, and hail, fiber cement siding provides lasting beauty, dependable protection, and peace of mind for decades.

Why Homeowners Choose Fiber Cement Siding

We’ve installed fiber cement siding on thousands of Colorado homes, and for good reason, it delivers performance, safety, and timeless curb appeal all in one product.

1. Durability and Weather Resistance

Fiber cement siding withstands intense sunlight, high winds, and severe temperature fluctuations. It resists cracking and expansion during freeze-thaw cycles, providing reliable protection against hail impact.

2. Fire and Pest Protection

Unlike wood or vinyl, fiber cement is non-combustible and impervious to termites and woodpeckers. In Colorado’s dry, fire-prone regions, having a fire-resistant siding offers an added layer of security.

3. Design Flexibility and Curb Appeal

From modern board-and-batten siding to traditional lap styles, fiber cement comes in a wide range of textures and finishes. ColorPlus® baked-on coatings provide fade-resistant color that keeps your home looking fresh for years.

In short, fiber cement delivers the perfect balance of form and function, an exterior that looks beautiful, stands firm, and enhances the overall value of your home.

How Fiber Cement Compares to Other Siding Materials

Colorado homeowners often compare fiber cement to vinyl, wood, or aluminum. Here’s how it stacks up:

Fiber Cement vs. Vinyl

Vinyl is lightweight and budget-friendly, but struggles in Colorado’s intense UV rays and hail. Fiber cement offers far greater impact resistance, color stability, and lifespan, making it a smarter long-term investment.

Fiber Cement vs. Wood

Natural wood siding is beautiful but requires constant maintenance to prevent rot and pest damage. Fiber cement recreates that authentic wood-grain look without the worry of warping or moisture intrusion.

Fiber Cement vs. Aluminum

Aluminum siding is prone to denting easily and can lose its finish over time. Fiber cement is thicker, sturdier, and more versatile in design, delivering a cleaner, more substantial appearance.
