I would like to finish my 2 car integral garage. 2 outside walls are below grade. Can I insulate the walls with standard fiberglass insulation? Can I cover fiberglass insulation with paneling (easier to install than drywall). What about vapor barriers? Should there be a vapor barrier over the foundation walls then insulation then another vapor barrier before the paneling?
What about being able to wash cars in the garage? What steps can I take to protect the finished walls?
