My husband is finishing our basement and installed 1 inch foam insulation to the exterior wall before framing and then installing fiberglass insulation. When he began drywalling he noticed moisture behind the fiberglass on the secrion of the wall that is above ground. At this point we are wondering what we could do to remedy this. I should mention we live in the northeast and it has been very cold of late. Since it is on the part of the foundation that is above ground, is there something we could do to the exterior wall to prevent this? The foundation is damp-proofed below gound already on the outside so it seems the issue is condensation from the cold air. What can we do...help!
