Susan writes from Whiting, Maine: "We live in downeast Maine. We turned our old, outdoor porch into a sunroom with a vaulted ceiling. We insulated with faced pink fiberglass. The walls are fine, but the ceiling keeps trapping moist air and then dripping late in the day...so we have not dared put up finished exterior (tongue & groove pine) ceiling. How should we have insulated? Foam board taped to the hilt? Plastic sheathing over the faced fiberglass? Ceiling/roof is not vented as it was an outdoor porch. There seems to be no one or clear answer, help please!"

Answer: This problem may be caused by the lack of roof ventilation. Please call the Owens Corning customer service department to discuss your situation in greater detail. The number is 1-800-Get Pink (438-7465).
