I'm finishing a 1950's basement in Michigan. The basement is dry, but before we started we ground out all cracks in the walls and filled them with hydrostatic cement and then used DriLock paint on the walls. Now I'm putting up steel stud walls, including around the perimeter and I'm trying to get advice on how to insulate these walls. Everything I've read says don't put anything directly against the block wall, because if warm moist air touches the cold block it will condense and you don't want insulation for eaxmple getting wet. Therefore, I'm planning to build the perimeter walls 1" away from the block.
How do I insulate? I don't want to glue rigid foam insulation board to the block wall because I'm afraid that if moisture gets between the wall and the insulation board mold will grow. I don't want to use fiberglass because I believe it will sag over time and end up resting against the block wall anyways. So, I'm thinking about using rigid foam board in the metal track between the studs, 1" away from the block wall, no vapor barrier. Does this make sense? Am I getting any R value by doing this or should I just not bother with insulation?
Thanks for the help.
