Just another case of NFPA #13 dictating how to build something. It's like NFPA went from protecting life and property at a reasonable cost to at any cost. I haven't found a way around it other than fill the space with insulation, usually not an option unless it's a small area. I have always thought that if I sent a sprinkler to UL for testing with a water truck from Phoenix and got UL to list the head with that water, every sprinkler installed in Phoenix would have to come from me. It would be the only sprinkler available that is Listed with Phoenix water.

Installing uprights in this space is very simple until you realize that the listed sprinklers required in this space require 1,000 sqft compartmentalization which would be very difficult and expensive. Does anyone have any related experience with a similar situation?
