I will be installing fiberglass batts as part of a bath remodel in a 1920s brick veneer house w/ 2×6 framing in Wisconsin climate (i.e. range from cold/dry to hot/moist, and that’s only June). That part of the house is heated by a hot water system, and there is a sizeable radiator in this room already.
I admit to being guilty of inattentive insulation practices in the past, so I’d like to do this right. In this case, is it better to use faced or unfaced batts? Approximately half the interior wall area will be covered with DensShield, which has an integrated waterproofing membrane- in fact the mfg specifically states not to use a vapor barrier behind the board. Will this also affect my choice of insulation?
Thanks
Andy

I'll add my vote to Jeff's for the unfaced behind the dense shield. I would also use unface throughout, because I have never had much success with keepiing kraft face tight to the sides of the studs, and it is harder to fit around wires, pipes and boxes in the wall.
FHB did an article on correct f/g installation last year. By taking the time to cut around obstruction in the wall you don't reduce the effectiveness of the insulation fron over compressing the batts and or missig spots and creating voids. Use a poly vp behind mr drywall for the areas that don't get the dense shield.
