I have a garage that is attached to my house on one side (side shown in the picture). I want to frame and insulate the walls, but I want lose as little space as possible (since the garage isn't very large to start with and the opposite wall has only 2 inches clearance between garage door rails and wall).
Can I frame the walls with 2x4 on the flat edge (Tapcons into the brick/cinderblock, maybe glue as well), and then install 2" thick foam board insulation?
I want some kind of framing, so I can hang things if needed, and possible finish the wall down the line.
I tried looking it up and couldn't find any questions where the person had them attached directly to a sturdy wall.
