March 15, 20233 yr Afternoon all. My SB is single-storey with a flat roof. Detail as shown: I will be running my services (Water, Electric, MHVR) through and between the posi joists, bringing the services into conflict with my insulation. I'm sure services vs insulation is as old as the hills, but would be interested in any best-practice tips, and in learning from anyone else's experiences. Thanks
