The Excellent Fire Resistance Value of James Hardie® Siding

Published April 10, 2020

There are many factors to consider when choosing new siding for your home. Product quality is one of the most crucial–you’ll want to make sure your new exterior is not only weather-proof, but fire-resistant as well. You may find James Hardie® fiber cement siding to be a prime example of this. But how well can this particular siding choice handle a fire? 


Lincoln Exterior Renovations, your siding and window installation expert, answers that here.

James Hardie® Siding and Fire Protection

Unlike many materials, fiber cement siding from James Hardie, such as HardiePlank®, offers great fire resistance. Wood usually feeds the fire, while vinyl melts instantly–but fiber cement will not ignite when exposed to a direct flame. It also won’t contribute fuel to a fire. In fact, this siding complies with ASTM E136 as a non-combustible cladding, and is recognized by fire departments across the country. 

That said, while James HardiePlank siding won’t allow fire to penetrate your home’s interior, it does allow heat to transfer. It is not 1-hour fire-rated, but it is still classified for use in certain 1-hour fire-rated Warnock Hersey and UL assemblies. Having a siding that is installed properly by exterior home contractors, and can resist burning for an hour, is especially handy for homeowners looking to keep themselves and their property safe in case of emergencies. 

Other Benefits of James Hardie Siding

With their exclusive HardieZone® System, James Hardie can help homeowners choose the siding product that perfectly suits their region’s specific weather patterns. Come rain, sleet, snow, high winds, or blistering heat, there’s a James Hardie siding that can effectively withstand them. What’s more, their fiber cement siding is a champion in increasing your home’s curb appeal. It comes in a variety of styles and profiles, and with their ColorPlus™ Technology, allows for consistent, baked-on finishes that last longer than a regular paint job.
