James Hardie Siding - Resistance to Fire

James Hardie fiber cement siding is becoming an increasingly popular choice for many homeowners due to the siding's extreme resistance to intense heat and fire. But how much resistance are we actually talking here?... Just watch this amazing video and see for yourself. 

As you can see, the average, run-of-the-mill vinyl siding melted within seconds of the fire heating it up. The wood siding, while it took it a little longer for the fire to ignite and consume it, burned longer and more intense than the vinyl siding. Obviously, that should be of no surprise because wood only adds fuel to fires.

But the James Hardie fiber cement siding passed the fire test with flying colors. While the fire appeared to be covering the bottom half the hardieboard sample, the hardieboard siding wasn't melting or warping at all. In fact, the fire basically burned itself out trying to eat away at the durable James Hardie siding.

Real-Life Testimonials

Here are several personal accounts of how the fire resistance of James Hardie fiber cement siding saved homes from what have been almost certain destruction.

"Three years ago I installed HardiePlank siding on my cabin in Tahoe. My cabin happened to be in the center of the hottest part of the fire but it survived. All 22 houses and cabins on the West side of my street were totally destroyed along with all cabins on the streets above and below me. The cabin next door burned completely. The firefighters said because the fire was so hot, if the Hardie siding had not been there I would not have a cabin." — Homeowner, Utah

"I want to thank your company for producing a truly fine product which saved our house from destruction. We were located in the worst part on the Angora Fire, all of the surrounding homes burned to the ground and my house is the only one standing on the block. We installed your cement siding about five years ago and it was the best investment we ever made. Thank you again." — Homeowner, South Lake Tahoe, Utah

"One well prepared house with hardieplank and boxed eaves that survived, and houses on either side that didn't. That tells you something about your product. I'm surprised anything survived this inferno. We're going to be requiring fire-resistant construction, will be listing James Hardie siding." — Kevin Dubler, Julian Fire Chief, San Diego Area
