We have a situation that has been talked about in the past but I can't remember what was resolved. Back to back sprinkler heads in a double 2X4 fire rated wall. The exception in the IBC 712.3.2 #3 deals with membrane penetrations and sprinkler escutcheon. What happens when you have a through penetration such as B/B sprinklers? There is no exception in section 712.3.1 of the IBC for sprinkler escutcheons in through penetrations and the manufacture states that you cannot fire caulk a sprinkler escutcheon. Would we need to use the donk style sprinkler esch and fire caulk around the pipe?
