Basement Insulation

Basement Insulation
I'm new to this forum and I'm looking for some help with a project. We are in the process of finishing our basement and are using 2 1/2 inch steel studs 16 inches on center during framing, placing them 1 inch out from the exterior concrete walls. What type of insulation do we use in our project? The only requirement we have (I believe) is to use a minumum of R11 per the building code. Do we use a vapor barrier or not? Any guidance would be greatly appreciated.

brucesmom,
Since you are using steel studs, you may want to use a W/T bottom plate so that it's easy to attach wood base molding, if applicable.
Since you are using R-11 minimum, you could use R-13. I would recommend Friction Fit Unfaced batts. Apply a 6 mil vapor barrier over the insulation using duct tape to secure poly to studs or you may staple your poly to joists, then apply your drywall over this. No need to tape seams of poly as long as they overlap.
Hope this helps!
