"Adding insulation to walls of an older house with no vapor. Here's an old study by the Forest Products Laboratory done in 1978 in Madison, WI on interior paint as a vapor barrier. Maybe people aren't using the plastic any longer and we just haven't caught on? If the paint weren't stopping the vapor where would the moisture escape to once it was trapped behind the drywall and in front of the plastic barrier? Doesn't it seem like a bad idea to let the moisture be held here? It seems it would be easier to handle the moisture inside of the house if it was obstructed from entering the drywall by the interior paint.
