Will mold grow between foam panels in the wall?
Hi, I am planning a new house in Wisconsin with 2" x 12" wood framing. The wall will be: drywall, 6" thick faced fiberglass batt, 3 foam panels 2" thick each, plywood sheating, house wrap, tar paper, corrugated stucco wrap, stucco. I am wondering if there is a problem with condensation between the foam panels causing mold. I am planning on making the drywall and plywood be air barriers. Also, instead of 2" x 12" wall studs, I am planning on two 2" x 4" studs with a 4" space between them for insulation.
The foam panels will be placed against each other but there may be a tiny space between them which will condensate when it is cold outside. The wall should be able to dry to the inside and the outside.
