Getting heavy condensation on the inside of the exterior boards.
I'm in a 50s bungalow in southeast michigan that has a walk in closet built into one of the attics. The closet was recently gutted when my wife discovered mold on the drywall on the only exterior wall of the closet. The exterior wall was poorly insulated and I figured that's why it was wet. I left it open for two weeks to dry out, which it did so I installed r-13 faced fiberglass insulation and left it for a week. I pulled back the insulation a week later to find the wall was soaked again. The exterior is aluminum siding on top of the old tile based siding a visual inspection did not reveal any leaks so I figure I'm dealing with an air issue that I want to solve before closing the wall up. I could always do a rubberized coating on the inside of the exterior wood boards but that won't solve the moisture problem that would rot the boards it would just prevent interior moisture and mold. I'm looking for a solution and welcome any help or ideas. Thank you
