Question: Should I reduce the amount of cold air in the attic?
Eric writes again from Hamburg, New Jersey: "Thanks - porch is not heated and results in a lot of cold air in the attic."
Answer: Actually, cold air in the attic is not a problem if the floor of the attic/ceiling of the living space below is properly insulated. In fact, ventilation is a good thing in the attic for the life of the roof deck and to avoid moisture problems.
