Nick writes from Horace, North Dakota: "I just purchased a home in North Dakota where the winter months get cold. I plan on installing a garage heater and insulating the garage. My dilemma is that there is already sheetrock on the ceiling, but no vapor barrier or insulation was installed. What are my options for insulating the ceiling and obtaining proper moisture barrier protection?"

Answer: I recommend blowing fiber glass insulation directly over the sheetrock in the attic.

Some building codes do not require a vapor barrier in your situation if the attic space has sufficient ventilation. If you need a vapor barrier, I recommend getting a "paint on" vapor barrier. This paint can be found at any local paint shop. Some building codes do not require a vapor barrier in your situation if the attic space has sufficient ventilation.
