James Hardie® Siding vs. Fires

Choosing siding with superior fire resistance improves the overall safety of your humble abode. James Hardie siding withstands fire better than other popular materials like vinyl and wood. It will not ignite flames even when exposed to a direct flame and won’t add fuel to the fire. Many insurance companies offer a discount for James Hardie siding because it is non-combustible.


James Hardie products won’t ignite under fire exposure, but they can still allow heat transfer. While they are not one-hour fire-rated, they can be combined with other components to qualify as a one-hour fire-rated assembly. A one-hour fire-rated assembly meets the requirements of ASTM E 119 tests.
