Fire-resistant solutions for the whole home exterior
Why fire-resistant materials matter now more than ever
Wildfire risk is reshaping how homes are designed and built. Climate-adaptive design helps harden the exterior with code-compliant materials that may resist ignition and slow flame spread. In many wildfire-prone areas, including Wildland Urban Interface (WUI) zones, building codes may require specific fire-performance standards for exterior applications. But fire risk extends beyond wildfire zones. A grill flare-up, stray ember, or electrical fault can put almost any home at risk, making fire resistance important for every homeowner.Help harden your home's exterior with the James Hardie family of brands
A more fire-resistant home isn't about one product. It's about the full exterior working together.

Hardie®
Hardie® fiber cement is noncombustible per ASTM E136, meaning it won’t ignite under direct flame or contribute fuel to a fire. It is ignition resistant, Class A fire rated, and WUI compliant for wildfire-prone regions. Along with other home-hardening measures, noncombustible Hardie® siding may help resist damage from external fire.*
