After kitchen rewiring and some minor plumbing work I am ready to insulate. The whole house, kitchen included, has what appears to be a foil/scrim/kraft type facing on fiberglass Johns Manville batts. The exterior sheathing is black cellulosic fiberboard and then brick veneer. No exterior vapor barrier from what I can tell. I need to put insulation back in the kitchen and was going to go back with what was there but it looks like the foil faced insulations are more of a commercial item. Not only that, it seems from the little reading I have done that for my location the foil as a vapor barrier is on the wrong side of the wall, and should be outside the sheathing if anything. So do I try to get the foil/kraft in the kitchen so it's like the rest of the house, or just go back with regular kraft? Or something else entirely? Thanks!
