Bathroom remodeling & insulation
Two questions on insulating exterior wall of tub/shower area. I am in northern Pennsylvania.
Currenlty the wall has hardboard siding and sheathing that is not vapor resistant, the rest is stripped down to the studs. I plan on adding fiberglass, then 6-mil poly, then cement board, and tile.
Is this method appropriate for the area i live in?
Second, there is a small area on this wall that was patched to shorten a window. This area is 2×2 ft. The sheathing is a foil backed foam board. vapor resistant. Is it acceptable to add fiberglass and poly before the cement board and tile for this area?
The layers, from out to in, are: hardboard siding, sheathing, studs and fiberglass, poly 6-mil, cement board and tile. (Only difference is in the patch area)
Or does anybody have a better recommendation?
