Core Features That Define Fiber Cement
- Composite Material: Cement, sand, and cellulose fibers combine into a dense, stable board that resists rot, pests, and fire better than wood or vinyl alternatives.
- Wood-Look Profiles: HardiePlank lap siding, HardieShingle, and Hardie Panel vertical siding mimic cedar, shakes, and modern farmhouse looks without the upkeep headaches.
- ColorPlus Technology: Color is baked into each board during manufacturing for a finish that resists fading, chipping, and peeling through South Shore seasons.
- Class A Fire Rating: James Hardie carries the highest fire rating available, slowing flame spread — note this slows but does not stop fire, so it is not fireproof.
- Coastal-Grade Durability: Fiber cement shrugs off salt air, humidity, and wind-driven rain — a big deal for Cohasset homes that face Massachusetts Bay weather.
- Strong ROI: Fiber cement siding delivers 144.9% return on investment, giving Cohasset homeowners one of the best exterior upgrades for long-term value.
- 30-Year Warranty: Every board carries a 30-year nonprorated limited warranty on materials, plus 15 years on the ColorPlus finish.
