fire resistance

Won't easily ignite

Fire resistance is the ability of a material or structure to withstand fire or high heat without igniting, collapsing, or losing integrity.

Building codes specify fire resistance ratings measured in hours: The wall has a two-hour fire resistance rating.

Materials like concrete and steel offer inherent fire resistance, while wood can be treated to improve it.
