Basement wall insulation
I am considering putting up walls in my basement. The home is 25 years old, and has a french drain. It has been a very dry basement, there is 1 small 6″ spot of condensation at the bottom of the block wall.
If I read you correctly, I should install 2″ of rigid foam insulation directly on the block walls, then stud them with no FB batts, and then add green sheetrock.
and no other vapor barrier?
What about my sump pump, (it almost never runs). should I place the walls on the outside of the pump, making the finished room a little smaller, or somehow build around the pump?
