unheated vestibules
(OP)
what do you guys do for unheated vestibules? they never wrote anything in the code about it
I put a note on a recent drawing that says 'unheated vestibule, open to above, no storage', fingers crossed.

RE: unheated vestibules
For areas like you state, we often put a dry sidewall or something along those lines. You can't just not protect an area because you don't know how, or because it is difficult.
To paraphrase Johnny Cochran: "If the standard don't omit, you must protect it."

Love the dry upright above!
RE: unheated vestibules
That diagram of the dry pipe head for the vestibule appears to violate the 2013 NFPA 13, 8.11.4.1.1. The head does not appear to be within code limit from the high point. What this actually approved by the AHJ?
RE: unheated vestibules
8.11 is for CMSA sprinklers..
Did I miss something?

You don't want to look at ESFR obstruction criteria for standard spray sprinklers.
We once had an AHJ that try to mandate all dry systems had to be galvanized. I asked where that came from. He pointed to the section on CMSA sprinklers. Again, location has meaning.
