Insulating a concrete block bathroom addition
I'm in zone 5A. This is our second winter in our 1948 ranch built out of concrete block. In the master bedroom there was an addition put on, also concrete block but a slab on grade floor. Needless to say, the heat in that room could also use help.
Recently a few tiles fell off the shower wall reveiling wet, moldy cement board and EPS. We gutted the shower and have been avoiding that bathroom for over a month (busy with other big projects, new baby, holidays, birthdays, and of course lack of $). But its even colder now in the bedroom and there is a breeze in the bathroom, so we really need to at least seal and insulate ( and hope to not find more issues).
What do you think is the best way to insulate?
2.5 in of polyiso, vaporous barrier, green board, tile?
I think the slab floor is a lost cause at this point...even though I would love to insulate and install radiant electric heat there.
I'd love to insulate the exterior but there is a great rock facade on the front and new stucco on the rest (plus lack of funds).
