Revision of the (US) International Wildland Urban Interface Code shows wide discussion on materials fire resistance. The code defines requirements for land use and for buildings within wildland urban interface areas, with the aim of reducing impacts and dangers of wildland fires for buildings and preventing building fires spreading to wildland. Ongoing discussions concern whether wall or deck materials should have one hour fire resistance (to prevent fire penetration) or whether flame spread limitations are sufficient, definition of ignition resistant materials (to prevent buildings catching fire from e.g. burning embers), fire performance requirements for wood construction materials and wood roofings as for well as garage doors, fencing, etc.
