Would like some advise on how to finish my basement interior with insulation. I live in South East Michigan area.
I have 2" foam board insulation on the exterior of the poured concrete wall. The board stops approx 6" from the exterior grade. I assume it goes down to the bottom of the basement wall. I have only been in the house for 6 months, however the basement does seem to keep a consistent temperature with the rest of the house.
This leave 3' of the interior basement uninsulated at the top of the wall. I would like to finish the basement (drywall with probably steel studs), however I am unsure on how to approach interior insulation.
Options that I can think of;
1. No interior insulation
2. Foam board (2") on the upper 3' of the interior.
3. Foam board (2") on the entire interior. This option leaves me concerned that by insulated both sides of the basement wall I will be trapping moisture and giving myself a big problem in a couple years.
Only evidence of moisture was when my inspector exposed a tie rod holes. I am knocking out all of these and filling them in with cork/concrete first.
