Adapted double stud walls
I am in climate zone 6 in Maine. I am looking to transition away from using foam in my wall assembly and I am (obviously) trying to optimize cost, performance, and durability. I have a sort of adaptation of a double stud wall that provides a good R-value and is cheap and easy to build. However, I am a little concerned about condensation. The wall, from the inside to the outside, is drywall, 2×6 dense pack cellulose cavity with studs 24″ oc, ZIP sheathing, the same 2×6 cavity with dense pack, 1.5″ rigid wood fiber, and then a rain screen. Should I be worried about moisture accumulating on the outer 2×6 studs or should they be able to dry adequately with the air gap near by? Attached is a rough plan view of the assembly.
I have read many of the other threads about double stud walls but if I missed something don’t hesitate to let me know.
