hopefully this is an easy question. When a fire wall terminates at an exterior wall then the walls on either side need to be 1 hour rated for 4 feet. Per 706.5 when the fire wall extends 18" beyond the exterior wall then there is no rating required on either side?
I have a fire wall on 1 side of a vestibule. if the fire wall extends 18" beyond, then the there can be glass directly against the fire wall?
