What I have is a exterior 8" cmu wall. The cells are grouted and the truss roof meets up and the wall cap is at the same roof pitch. Fire Marshall indicated that it needed to be a certain UL listing.
Actually I thought the wall was already a 2 hour rated wall so that is why I was asking. Maybe I am missing something
