Foil faced fiberglass insulation…..what to replace it with?
I’m renovating my master bath, and for a number of reasons had to remove both the drywall ceiling and the foil faced insulation (to the attic) in the ceiling. I wanted to take this opportunity to better insulate the ceiling but find that Foil faced insulation doesn’t seem to be used for this anymore. My understanding was that it was not only a vapor retarder, but a “thermal” reflector. What should i replace it with? Kraft faced? Vapor barrier with unfaced?
I should mention……i have to do this from underneath, so blown in is not an option…..i was going to “push the batts” up between the joists/rafters and staple to ceiling side of structure
Sorry if this seems like a silly question…..any help would be appreciated.
