Basement Insulation Options (half concrete wall)

Just in the process of finishing the basement of a new used home we purchased.  We are in Vancouver BC.  I'm leaning toward the following:

  1. Attach XPS ridgid to the concrete with it going up and over to the bottom plate
  2. Use spray foam to seal all the cracks and gaps
  3. Remove old insulation and replace with Roxul
  4. Place a vapour barrier over top of the Roxul on the top section
  5. Frame a pony wall 1/2" from the ridgid that will extend up to where the bottom plate making a shelf type arrrangment.
  6. Once the framing has been completed fill the voids with Roxul.
  7. I'm either going to use Dricore or 2" xps with 3/4" t&g plywood with hardwood nailed to that.

I've video a lot videos on this type of arrrangement and Building Science would NOT put a vapour barrier on anything below grade>.

Comments/suggestions?

Thanks, Dennis
