Hey everyone, I am looking to install my wood stove in my living room, and want to get rid of the old drop ceiling and put up drywall instead. The attic has kraft-faced insulation stapled to the ceiling joists (paper facing down) and then there is blow-in insulation on top of everything. The trouble is that the faced insulation is sagging and coming down in places. So, I would like to staple up plastic to hold it all in place before I put the drywall up. Will this be an issue if I add another vapor barrier on the underside of the joists (where the kraft-faced paper is also at)? My house is in Central PA. The attic has some venting at the peak, but they didn't cut out the OSB everywhere underneath the ridge vent.
