Protecting Homes From Wildfires

James Hardie fiber cement has been tested by various IAS Certified Laboratories to ASTM International standards. The results: not only is James Hardie non-combustible, it also has a flame spread index of zero and a smoke developed index of less than five. That’s protection for your home buyers.

Some wood and vinyl sidings are combustible and will ignite and add fuel to a fire. According to University of California researcher Stephen Quarles, combustible siding, like wood and vinyl, can make your home vulnerable to wildfire by making it easier for fire to penetrate through a horizontal or vertical lap joint between individual pieces of siding, into the stud cavity and then into the living space of a home. If no one is present to extinguish the fire, the home could be lost. When wildfires are present, more homes burn due to contact with embers than flames, and it’s times like these where non-combustible exterior siding can add an extra layer of protection to your home.

During a typical house fire, fiber cement siding — when combined with certain one-hour related Warnock Hersey and UL assemblies, will make a wall assembly that resists flames and heat damage for as long as an hour, buying home owners and fire fighters critical time to extinguish flames before extensive damage is done. Because of its non-combustible properties, James Hardie siding is recognized by fire departments nationwide.*

Looking Toward the Future of Wildfire Protection

As devastating as the 2018 wildfires have been, many experts predict that they will continue to get worse over time as annual temperatures creep higher and conditions get drier. For these reasons, it’s necessary to look toward the future and develop long-term solutions to better protect homes before disaster strikes.

* James Hardie siding complies with ASTM E136 as a noncombustible cladding and is recognized by fire departments across the U. S. including Marietta, Ga., Flagstaff, Ariz. and Orange County, Calif. Fiber cement fire resistance does not extend to applied paints or coatings, which may be damaged or char when exposed to flames. ¦
