I am re-finishing my basement and will be using fiberglass batts for insulation. Should I install the vapor barrier between the studs and the concrete wall or between the studs and the drywall (sealing in the insulation in)? I have had friends of mine who build/remodel houses give me both as the correct way. How do I correctly seal the vapor barrier as well? So I am looking to the TOH masses for a consensus. I live in Belgium Wisconsin along Lake Michigan, the basement is poured concrete 8" thick and 8' high. Finishing with 2X4, insulation, vapor barrier and drywalling over. Also had interior drain tile repairs this spring and have the waffle board that was installed along the bottom edge when it was re-concreted. If the correct way is in-between the studs and concrete wall, can I just tuck the vapor barrier into the waffle board to allow any moisture through it and under the floor and into the new drain tile?
