My garage wall ranges from 8" to 14" above grade and would like to know the best way to insulate the exterior walls. I was planning on putting 2" SM on the interior side below the floor.
It is a 5' poured concrete wall. The top of the wall at the back corner is 8" above grade and the front is 14" above grade. Again, what is the best product to insulate the exterior concrete? I live in Central Ontario.
