Frame partition walls AFTER strapping ceiling
I’m remodeling the upstairs of a 1.5 story Cape. I’m installing continuous interior foil faced polyiso from the 1st floor top plate, all the way up the rafters, across the collar ties (ceiling joists) and back down the other side, in addition to up the two gable walls. It will all be seam taped. I’ll then be leveling the ceiling with 2×3 strapping, while also creating a cavity to run electrical with minimal disturbance to the polyiso air seal.
Does anyone see any issue with me framing my interior partition walls AFTER installing the strapping? This would allow for longer runs of strapping, a continuous cavity for electrical from room to room, and because of my order of operations, make my polyiso install easier.
