Question:

Why is the outside wall in the closet wet?Additional info needed.?

This question was raised by MIKU HAUONE I felt the answer by LJC was the best answerIn my situation I have discovered there is no insulation in the wall, just around the heat registers and in the atticThe house was built in the 1950s, we thought it was insulatedI don’t think this happened last winterTwo things different, a humidifier that works (mounted on the furnace), we painted the exteriorI don’t believe there is a vapor barrier etherThe roof was new 3 years ago and no signs of a leak, vented at the eves, ridge and has three roof ventsIn the basement all the wall stud spaces have insulation stuffed up into them resting on the sillThe one wall I washed with soap and water, removing the mold and drying itIt has remained dryAnother factor is, we live in southwest MI and we’ve had a bad rain storm and several bad snow stormsThe house is 35’ long and 24’ wide the long side faces north on the front and south on the backSo, any other ideas?

Answer:

Its too keep the heat in the food and protects it when cooking itLike garlic bread that's in foilIt cooks nice and evenly and soft, as soon as you take the foil off it gets crusty and can burn.
You say that there is no insulation in that wallFeel itIt is probably really coldThis is where the warm moist air on the inside of the house will condenseIt is amazing how much water can come out of a persons breathI noticed the same thing in my bedroom closetIt got worse when I switched away from incandescent bulbsYou might want to get a closet dehumidifierI like the convenience of theseThe one that comes with a hanger is great for the spot on the rack right next to the wall that seems to get dampSmall investment for saving a ruined jacket.
