Faced or Unfaced batt insulation in basement walls?
I am finishing my below grade basement. I put Owens Corning R-5 against the slab walls. Now my question is do I put faced or unfaced batt R-15 between stud spaces on the exterior walls?

If you taped and sealed the R-5 rigid insulation, then you do not need faced batt insulation. I believe your intent is to use the R-5 to prevent conditioned air from hitting the cold surface of the foundation wall. The best way to achieve this is by taping and sealing all the seams of the R-5.
I attached an article that will provide some more insight to what I'm saying above. Good Luck!
