We have a multistory hotel building with the rooms opening to an exterior corridor. There is Exterior Insulation Finish System (EIFS) along the walls of the exterior corridor.
NFPA 13 (2022), Section 220.127.116.11 allows omission of sprinklers from exterior exit corridors where the exterior wall of the corridor is at least 50% open and where the corridor is entirely of noncombustible construction.
It seems from research that EIFS is considered combustible and would require sprinkler protection along the exterior corridor.
Has anyone done more research on this or has this come up before for other projects with EIFS in the exterior corridors and ultimately required sprinkler protection?
Thanks in advance.
