2006 Utah UWUI Table 503.1 N.C. exterior-wall addition
When Table 503.1 returns an N.C. result, the 2006 Utah UWUI adds both a one-hour exterior-wall rating and a noncombustible exterior surface.
This conjunctive row covers documented duration and noncombustibility for a siding or wall product only. The official hazard, water-supply, and defensible-space inputs must produce the N.C. result; the complete wall, log-wall allowance, local map, project, and approval remain separate checks.
Published requirement text
“Exterior walls shall have a fire-resistance rating of not less than 1-hour and the exterior surfaces of such walls shall be noncombustible.”
