Fire Resistant Siding

Fire Resistant Siding & Noncombustible Cladding in Colorado

Combustible siding can ignite from radiant heat before flames ever arrive. We install fiber cement, metal panel, stucco, and FRT wood systems that meet Colorado's exterior cladding requirements.

Quick Answer

Fire-resistant siding is noncombustible or fire-rated exterior cladding that resists ignition from radiant heat and direct flame contact. Blaze Blocker installs fiber cement (such as James Hardie), metal panel, stucco/EIFS, and fire-retardant-treated wood siding — all compliant with Colorado's wildfire resiliency code.

Radiant heat from a nearby burning structure or vegetation can ignite vinyl or untreated wood siding without any flame contact. Noncombustible cladding removes that pathway.

Why siding matters in a wildfire

Siding is the vertical face of your home that radiant heat strikes first. Vinyl melts and untreated wood ignites well before the fire front reaches the wall — opening a path into the structure.

Fire-resistant cladding, combined with proper trim and sealing at penetrations, keeps the wall assembly intact through ember showers and radiant exposure.

Siding systems we install

  • James Hardie fiber cement — Noncombustible, durable, and available in many profiles — a popular Colorado choice.
  • Metal panel siding — Fully noncombustible cladding with a clean, modern look.
  • Stucco & EIFS systems — Continuous noncombustible coverage well suited to many home styles.
  • Fire-retardant-treated (FRT) wood — Treated wood siding for homeowners who want a natural look with improved fire performance.

CWRC-compliant, every time

All materials and installation methods meet the Colorado Wildfire Resiliency Code (CWRC). We document completed work so your insurer can use it for premium review, and align every project with the IBHS Wildfire Prepared Home™ standard.

Done right, down to the details

Cladding only performs if it's detailed correctly — at trim, corners, soffits, and around windows and vents, where embers and heat concentrate. We install the full system, not just the panels.

You'll receive documentation for your insurer and for IBHS Wildfire Prepared Home™ certification on completion.

Common Questions

What is the best fire-resistant siding?
Noncombustible options — fiber cement (e.g., James Hardie), metal panel, and stucco — offer the strongest fire performance and meet Colorado's cladding requirements. The best fit depends on your home's style, budget, and HOA.
Is vinyl siding a wildfire risk?
Yes. Vinyl can melt and ignite from radiant heat before flames reach the wall, exposing the structure underneath. Replacing it with noncombustible cladding is a common hardening recommendation.
Does new siding qualify for insurance mitigation credit?
Many Colorado insurers recognize documented fire-resistant cladding as part of a mitigation package. We provide a completion certificate you can submit for premium review.
