On the exterior, we added a rain screen made of 1x3 furring strips over top of our water resistive barrier (#30 felt paper).

You can then strap furring strips over the insulation (attached through the insulation into the masonry) and hang drywall or resilient channel and then drywall from the furring.Polyisocyanurate foil faced rigid foam runs ~R6/inch, while closed cell spray foam runs R6 to R6.4 and provides a better air barrier.Alternatively, you could stand-up a 2x3 or 2x4 studwall in-front of the masonry wall (leave a 1/2" gap between the masonry wall and the studs and spray the stud cavities (and space behind the studs) with closed cell spray foam.  

They nailed 1x2 furring strips to the bottom of the joists, and then used long staples to attach the tiles to the furring strips.
