My house (currently being constructed in SW Colorado) will have Sheetrock walls and ceilings throughout. Will vapor barrier paint on the ceilings prevent most of the air and moisture migration from the living space into the attic?
There are several dropped ceiling soffits wrapped in sheetrock. If I paint these per above, and fill the inside cavity with the same blown-in insulation used throughout the attic (R60 cellulose), will I need to do any further sealing of the soffits?
Thanks for any help or suggestions!
