Exterior rigid foam - horizontal furring?
I am designing a small commercial building for a client in climate zone 5A.
The design has two thermal challenges I am looking to get opinions on. For brevity, I will address only one here.
For detailing purposes and ease of constructibility, my initial thought for the exterior wall system was to use traditional 2x4 metal stud framing with batts. In addition, I was wondering if the group could post their thoughts on running horizontal furring at 24" on the exterior with 1.5" rigid in between, which would limit the thermal bridging to the intersections of the studs/furring. Then maybe an insulated sheathing over the whole assembly with drywall inside.
Then I wondered if furring / rigid on the interior would be easier and allow better ventilation on the exterior, but I haven't seen this detail before, so maybe there is a reason to avoid.
