Would installing vertical furring strips next to the sheathing and behind the rigid foam help the wall to breathe?
Would installing vertical furring strips next to the sheathing and behind the rigid foam help the wall to breathe and still maintain R values? I am in Zone 7 and considering adding foam to the exterior since I am residing. Or is this just overkill? Thanks for any replies.
My wall from the inside out would consist of:
Poly Vapour barrier
2"x4" studs ( fiberglass batt insulation)
** 1/4" furring strips **
2" rigid foam
Tyvek building wrap
Hardie Plank siding
