Wall service cavity insulation
Question is asked with climate zone 6 in mind.
Most wall service cavity examples seem to be made with 2×4’s “on the flat” perpendicular to studs, making 1.5” deep horizontal service cavities between the vertical stud bays and drywall. Is there widely available insulation that could be added to these horizontal service cavities? I’m having a hard time finding 1.5” batts. Would anyone recommend turning the strapping on edge to make the service cavity 3.5” and therefore more accommodating of conventional batts? Would that be problematic for mounting drywall?
