I am working on a small mixed-use building with commercial space on the first floor and an apartment with loft above. Part of the apartment has a cathedral ceiling, which needs to have sprinklers on the slope. No other options. The roof is framed with 2x10s and they plan to use a spray in foam insulation the entire depth of the joists. My thought was if they took one joist bay and only put 5" of insulation and create a space to run the pipe. Would that be sufficient to prevent pipe from freezing? I also thought about putting a small grate at the bottom and top of the channel to allow heat to flow into the space. Has anyone done anything like that before? Thoughts on weather it would work? Not a lot of options and I don't want to go with an antifreeze system
