Did you know that there are over 350,000 house fires every year in the United States? Here in coastal New England, house fires are most prevalent during the spring season when strong winds blow off the coast. It’s a time of year when you’ll want to think about home fire protection for peace of mind. However, the truth is that you need home fire protection all year long — especially since December and January are peak times for house fires. But is James Hardie fire resistant? Can it give you peace of mind in the event of a house fire?
If you worry about house fires, you can have peace of mind when you install siding that can potentially save your life. Let’s talk about how James Hardie takes the heat and what you need to know about class A fire resistant siding.
Is fiber cement siding fireproof?
No siding is truly fireproof, but James Hardie fiber cement comes very close as a non-combustible, Class A rated material.
The accurate terms are non-combustible and Class A, not fireproof. That distinction matters when you plan a fire-smart exterior. Knowing the real fire performance helps you set the right expectations.
What Homeowners Need to Know:
- Direct answer: No siding is genuinely fireproof, though fiber cement performs exceptionally. James Hardie fiber cement is non-combustible and Class A fire rated.
- What that means: Class A is the highest fire rating for residential siding. It is tested in accordance with ASTM E84.
- No added fuel: Fiber cement will not ignite from a direct flame. The material will not contribute fuel to a fire.
- Paint caveat: Fire resistance does not extend to applied paints or coatings. These finishes may char when exposed to flames.
- Why it helps: Non-combustible siding adds a meaningful layer of protection. It supports a more fire-conscious home exterior.

Should I choose fiber cement or vinyl siding?
Choose fiber cement for durability and fire resistance, or vinyl for lower upfront cost and faster installation.
Both materials perform well, so the right choice depends on your priorities. Fiber cement leans premium, while vinyl leads on value. Knowing how they compare helps you invest with confidence.
What Homeowners Need to Know About Fiber Cement Siding vs Vinyl:
- Core difference: Fiber cement blends cement, sand, and cellulose, while vinyl is molded plastic. The composition makes fiber cement heavier and more durable.
- Fire safety: James Hardie fiber cement is non-combustible and will not ignite from a direct flame. It carries a Class A fire rating per ASTM E84.
- Cost honesty: Vinyl averages $18,000 and installs faster. Fiber cement averages $21,500 and delivers a stronger long-term return.
- Resale strength: Vinyl siding returns 97% at resale nationally. Fiber cement returns an impressive 144.9% on the same report.
- Curb appeal: James Hardie resists fading, rot, and insects with baked-on color. It mimics real wood grain better than most vinyl.
Option | Pros | Cons | Best For | Price |
Vinyl Siding | Lower upfront cost, fast install, 97% ROI | Less durable, can warp in high heat | Budget-focused homeowners | $18,000 avg |
James Hardie Fiber Cement | Non-combustible, 144.9% ROI, wood-like look | Higher upfront cost, heavier material | Long-term value and fire resistance | $21,500 avg |

The Short Answer: Yes, Hardie Is Class A Fire Resistant
So is James Hardie fire resistant? Yes — James Hardie® fiber cement siding is Class A fire resistant, the highest residential fire rating available under ASTM E84.
- Class A fire rating when tested in accordance with ASTM E84
- Non-combustible — will not ignite when exposed to a direct flame
- Will not contribute fuel to a fire
- Note: fiber cement fire resistance does not extend to applied paints or coatings, which may be damaged or char when exposed to flames.
Learn why Coastal Windows is a James Hardie Elite Preferred Contractor serving 730+ New England towns.
What Does "Fire Resistant" Mean? (And Why It's Different from "Fireproof")
Let’s first discuss the meaning of fire resistant. When a building material is fire resistant, it means that the material contains the fire in a specific area to slow the spread. The building material will continue to burn for a specific amount of time–for example, 1 hour.
After that timeframe, the fire will continue to spread through the home.
No exterior siding is truly “fireproof” — but Class A fire-resistant materials like James Hardie® can slow flame spread long enough for your family to evacuate and for first responders to arrive.
So when homeowners ask “is Hardie board fireproof?” the technically accurate answer is no — but it IS Class A fire resistant and noncombustible, which is the highest performance tier you can buy.
Is Hardie® Board Combustible? Understanding Noncombustible Materials
No — Hardie® siding is non-combustible, will not ignite when exposed to a direct flame, and will not contribute fuel to a fire. So when homeowners ask, “is Hardie board combustible?” the answer is no — and the distinction between “noncombustible” and “fire-resistant” is important. A material can be fire-resistant without being noncombustible. Hardie® is both.
- Hardie® siding is non-combustible — it will not ignite when exposed to a direct flame
- Hardie® backer boards are recognized as non-combustible when tested according to ASTM E136
- Hardie® fiber cement products have a Class A fire rating when tested in accordance with ASTM E84
This combination of non-combustibility and a Class A fire rating is what makes Hardie® a preferred choice for fire-conscious homeowners across New England.
What Is the Fire Rating of Hardie Board? (Class A Under ASTM E84)
The fire rating for Hardie board siding is Class A under ASTM E84, the highest rating available for residential siding materials. Cement siding fire rating standards are governed by ASTM E84, and Hardie’s Class A score is the best available.
Below, we break down what those test numbers mean in real-world terms — and how Hardie qualifies for 1-hour fire-rated wall assemblies.
It’s worth noting that 1- and 2-hour fire-rated wall assembly designs featuring Hardie® siding are available above-code options. They are not a standard feature of every installation, but are available when a project requires it or a local jurisdiction mandates it.
Here’s what Hardie’s Class A fire rating means in practice:
- Noncombustible: Verified as noncombustible per ASTM E136 — Hardie® siding will not contribute fuel to a fire
- Class A fire rated: Tested per ASTM E84 with a flame spread of 0 — the best possible result under that standard
- Above-code wall assemblies: 1- and 2-hour fire-rated wall assembly designs featuring Hardie® siding are available when local jurisdiction requires it or a project calls for a higher level of fire protection
What “Class A Fire Rating” Means for Hardie® Siding
James Hardie’s Class A fire rating — the highest residential rating — comes from testing in accordance with ASTM E84, the industry-standard test method for surface burning characteristics of building materials.
Here’s what that means in plain terms for noncombustible siding:
- No ignition: Hardie® siding is non-combustible, will not ignite when exposed to a direct flame, and will not contribute fuel to a fire.
- Coatings caveat: Note that fiber cement fire resistance does not extend to applied paints or coatings, which may be damaged or char when exposed to flames.
- Whole-home protection: The use of noncombustible siding, combined with other fire mitigation measures, can help harden a home against external fire.
For broader context on how Hardie performs across all conditions — moisture, impact, and fire — see our fiber cement siding for New England homes overview.
Hardie® Backer Board Fire Performance
Hardie® Backer Board is James Hardie’s cement board product — distinct from HardiePlank lap siding. It carries its own verified fire performance credentials.
Hardie® Backer Board is recognized as non-combustible when tested according to ASTM E136. It is also verified for use as a fireplace facing, making it one of the few exterior and interior cement board products with documented fire performance across multiple applications.
Homeowners often ask, “is Hardie® Backer Board fireproof?” — and while no exterior or interior material is technically “fireproof,” Hardie® Backer Board is recognized as non-combustible per ASTM E136. 1/4″ Hardie® Backer Board can be used as a component in 1-hour fire resistive construction per National Evaluation Report NER-405.
Homeowners searching for the 1/2″ Hardie® Backer Board fire rating will find that all Hardie® Backer Board thicknesses share the same non-combustible classification per ASTM E136 — the distinction in thickness relates to application and installation requirements, not fire performance classification.
HardiePlank®, HardiePanel® & HardieShingle®: All Part of the Hardie® Fiber Cement Family
James Hardie’s primary exterior siding products — HardiePlank® lap siding, HardiePanel® vertical siding, and HardieShingle® — are all Hardie® fiber cement products.
Per James Hardie, Hardie® fiber cement products are noncombustible and/or have a Class A fire rating when tested in accordance with ASTM E84.
Product | Profile | Popular Use in New England |
HardiePlank® Lap Siding | Traditional horizontal lap; mimics wood clapboard | The most popular Hardie® fiber cement product across MA, NH & ME — versatile for colonial, craftsman, and cape-style homes |
HardiePanel® Vertical Siding | Large-format vertical panels | Accent walls and modern architectural styles; often paired with HardiePlank® for contrast |
HardieShingle® Siding | Fiber cement shake | Popular on Cape-style homes throughout coastal MA and ME; replicates the look of wood shake without the fire or rot risk |
All three are Hardie® fiber cement products and share the same verified noncombustible classification — no individual sub-product fire ratings are claimed beyond the umbrella Hardie® fiber cement designation.
Explore the different types of James Hardie siding to see which profile fits your home’s architecture.
How Does Hardie® Perform in a House Fire?
Wondering how does Hardie board perform in fire? Here’s how fiber cement works during a house fire. James Hardie will not ignite when exposed to a direct flame. It also will not contribute fuel to a fire. Essentially, you can compare Hardie® to a cooking pan. You can expose it to heat and it won’t burn. But you’ll need an interior wallboard to resist burning for 1-hour to buy you time.
“The only reason why we are alive today and that our own home wasn’t engulfed was thanks to your product,” -Simone V., homeowner and fire survivor. Source: James Hardie®.
How Does Hardie® Compare to Other Fire-Resistant Siding Materials?
When a home with wood siding catches on fire, it can be devastating. That’s because flames spread like–well, wildfire–when it comes in contact with wood. Lumber also ignites at a lower temperature than vinyl, coming in at 500 degrees F compared to 750 F for vinyl.
And the terrifying reality is that a house can burn down to the ground within 5 minutes. This leaves little to no time to escape.
Wood Catches Fire and Spreads it Quickly
When a home with wood siding catches on fire, it can be devastating. That’s because flames spread like–well, wildfire–when it comes in contact with wood. Lumber also ignites at a lower temperature than vinyl, coming in at 500 degrees F compared to 750 F for vinyl.
And the terrifying reality is that a house can burn down to the ground within 5 minutes. This leaves little to no time to escape.
Vinyl Siding: The Budget Alternative
Like James Hardie, CraneBoard® vinyl siding will help slow the spread of a fire. Vinyl will not melt until it reaches 750 degrees F.
For homeowners who want fire-slowing performance at a more accessible price point, see our companion guide: is vinyl siding fire resistant.
James Hardie® Siding Can Save Lives
Since Hardie® is non-combustible, there is documentation of this fiber cement siding saving lives during a house fire. It’s also Class-A fire-resistant in accordance with ASTM E84.
Does James Hardie® Siding Lower Home Insurance Costs?
Many homeowners ask if James Hardie® siding can lower their home insurance costs. The answer, per James Hardie: because Hardie® products are non-combustible, many insurance companies offer a discount.
For homeowners in Massachusetts, New Hampshire, and Maine — where older housing stock and coastal weather conditions can already affect insurance premiums — it’s a conversation worth having with your carrier.
- Hardie® fiber cement is non-combustible — a property that some insurance carriers recognize when calculating premiums.
- James Hardie recommends sharing fiber cement siding’s fire-resistant qualities with your insurance carrier.
- Discounts vary by carrier, state, and policy — your insurance agent is the right source for what applies to your specific policy.
Talk to your insurance agent about whether upgrading to James Hardie® fiber cement siding qualifies your home for a non-combustible siding discount on your policy.

Fire rated siding in New England stays stable in high summer heat, and Hardie fiber cement will not ignite from a direct flame.
Heat stability and fire resistance work together in quality siding. Fiber cement holds its form when temperatures climb. Knowing how it performs helps you plan a resilient summer-ready exterior.
What Homeowners Need to Know:
- Heat performance: Fire rated siding stays stable through high summer heat. Hardie fiber cement will not ignite from a direct flame.
- Class A rating: Hardie fiber cement products are Class A rated under ASTM E84. This is the top residential fire rating.
- One-hour assemblies: A 1 hour fire rated siding assembly resists fire spread for sixty minutes. These are above-code add-ons, not standard installs.
- Cement board: Quarter-inch HardieBacker can join a 1 hour fire rated cement board assembly per NER-405. The board is non-combustible per ASTM E136.
- Set expectations: Standard installs already use non-combustible Hardie products. One-hour assemblies are an extra, above-code upgrade.
