I recently glued 2' 4x8 (XPS) rigid foam to my basement walls. I cut pieces to fit between the joists and along the rim joist. I put pieces on top of the cement wall, and then foamed around all those pieces, and the bottom of the 4x8 sheet. I then installed a 2x4 wall in front of and touching the rigid foam.
Do I need to put unfaced batts in the bays ?
