Re: GBlist: Masonry wall insulation -Reply

I wonder if the description of the masonry wall insulation in Home Energy
might have left out a couple of important details--so, just in case, allow
me to restate the obvious: the wet-spray insulation should dry out before
it is covered, so it doesn't end up growing mold. There should be a
continuous vapor retarder, such as clear poly sheet, installed over the
insulation. The drywall should be mudded or caulked to stop air leaks, at
penetrations like pipes, outlet boxes, air conditioners etc., and along the
bottom plates.
