  • All About the Fire Resistance of James Hardie® Siding

One of the most notable qualities of the James Hardie® fiber cement siding is its fire resistance. PJ Sullivan Exteriors, one of the top siding and roofing replacement companies in the area, discusses more below.

James Hardie’s Fire Protection Performance

In case a fire breaks out, you want to determine whether the wall of your house can protect you while you and your family are seeking safety. Home exteriors covered with wood siding are more likely to go up in flames quicker than vinyl siding. However, when the same thing happens to vinyl, expect the material to melt away if the flames aren’t put out immediately.

James Hardie’s fiber cement siding won’t ignite when exposed to a direct flame, nor will it serve fuel to the fire. According to the most knowledgeable siding contractors, the product complies with ASTM E136 as a non-combustible cladding. This standard for fire protection on building materials is the reason why the brand is recognized among fire departments across the United States.

The Importance of a Fire-Rated Assembly

Despite adhering to fire performance standards, you must be aware that James Hardie siding alone isn’t one-hour fire-rated. Even with the product being exposed to the fire, heat will transfer. For utmost fire protection for your home, the siding must be a part of a building assembly.

A one-hour fire rating is given to an assembly that can maintain the ability to confine a fire for at least an hour. For example, a one-hour fire-rated assembly composed of James Hardie siding and interior wallboard buys the homeowners time to escape the property and the firefighters to respond to the emergency.
