Reply to comment by rumenocity5 in Do i need vapor barrier or can i leave it and drywall over it? by slickwrick21

This is probably the best recommendation, honestly. I've also heard of people doing foam board against the concrete and then batting over that.

I also second the other recommendation to see if there's code specific to your area since it is likely high moisture/humidity

The problem is that concrete is a huge thermal mass. Any change in humidity in the conditioned space will cause a surface effect on the concrete and adversely affect the fiberglass insulation and wood framing.

I did that, but I used rockwool which is moisture resistant.
