31.   There is not enough to allow water vapor to escape, and the water vapor is condensing on the cool, north side.

32.   These holes will allow trapped moisture vapor to escape harmlessly to the outside instead of condensing on the cold glass of the storm window.

33.   This extra humidity will eventually condense on insulation, timbers and metal, causing them to deteriorate, rot or rust.

34.   This will keep the wall warmer, and water vapor is less likely to condense on it.

35.   This will keep the ducts warmer, and moisture is less likely to condense on them.

36.   This moisture, in the form of water vapor, condenses on the cool floor into water.

37.   This will help some, even though the closet is unheated, because the walls will be warmer and water vapor will be less likely to condense on them.

38.   Warming up that ceiling will help prevent anything from condensing on it.

39.   Water vapor builds up in the closet because it cannot escape, then condenses on a cool surface and you can get mold growing.

40.   Water vapor condenses on that cool area, making it damp.
