What Is Fiber Cement Siding Called? The Ultimate Name Breakdown

Shirley Jun 01, 2026

When homeowners and builders begin researching exterior cladding options, the question "what is fiber cement siding called" frequently arises. This specific inquiry points to a versatile and durable material that has earned numerous aliases within the construction industry. Primarily known as fiber cement siding, it is also referred to by brand-specific names and descriptive terms that highlight its composition. Understanding these various names helps contractors and homeowners communicate effectively when sourcing materials or discussing installation specifications. The product is celebrated for its ability to mimic the look of wood without the associated maintenance, making it a staple in modern residential design.

Common Names and Terminology

To answer "what is fiber cement siding called," one must look at the most widely accepted trade name. In virtually every market, the product is sold under the general descriptor "fiber cement siding." This term accurately describes the core components: cellulose fiber, cement, and silica sand. However, because the material is so durable and low-maintenance, it is often simply called "fiber cement" for short. This shorthand is common among contractors and DIY enthusiasts who understand the product's robust nature.

Brand Names and Proprietary Terms

While the generic term is useful, much of the market recognition for "what is fiber cement siding called" is dominated by specific brand names. These companies have become synonymous with the product itself due to their longevity and market presence. When discussing popular options, names like HardiePlank, Fiberon, and LapPlex immediately come to mind. These brands often have slightly different manufacturing processes, but they all fall under the umbrella of fiber cement technology.

  • HardiePlank: Perhaps the most recognizable name, often used as a verb (e.g., "I HardiePlanked my house").
  • Fiberon: Frequently chosen for its wide range of colors and styles.
  • Kraken: A newer entrant known for its impact resistance and warranty.
  • Evergreen: Marketed for its wood-like appearance and nailing surfaces.

Descriptive and Functional Names

Beyond brand loyalty, the material is often identified by its functional benefits, which inform what fiber cement siding is called in descriptive terms. Because it is made from cement, it is inherently fireproof, rot-proof, and pest-proof. As a result, it is frequently labeled as a "weather-resistant barrier" or "exterior cladding" in technical manuals. Builders might specify it as "non-combustible siding" to meet strict building codes in fire-prone areas, highlighting its safety profile over its aesthetic name.

Material Composition and Nicknames

The composition of the material directly influences what fiber cement siding is called in industrial settings. The mixture of Portland cement, wood fibers, and sand creates a product that is extremely dense and heavy. Due to this density, it is sometimes colloquially referred to as "cement board" or "composite siding." While these terms are not entirely specific to the finished shingle or panel, they accurately describe the foundational materials that differentiate it from pure polymer or vinyl alternatives.

Marketing and Aesthetic Terminology

Finally, the answer to "what is fiber cement siding called" expands when considering its role in curb appeal. Manufacturers often market these products under terms that evoke the natural materials they replace. You will hear it described as "synthetic stucco" when applied in a smooth, monochromatic finish, or "wood-grained siding" when the print mimics oak or cedar. These aesthetic-driven names help consumers visualize the final look, bridging the gap between the technical definition and the desired design outcome.
