Garage Framing Question
I am converting my garage into a living room, and have a question about framing.
I have 11 foot ceilings, soon to be 10 foot once I add the floor. 7' is 2x4, and the bottom 3' is concrete block.
Of course, the block sticks out further than the 2x4. I need advice on how best to even this wall out. I want to add a 1x3 or 2x3 frame from floor to ceiling, and then drywall.
I've been told that 4" of insuation (R13) is enough, so I do not intend to bring out the 2x4 any further.
This new frame will be flush against my block, but there will be a 7"+ gap between the frame and the 2x4's.
(1) Will a 1x3 frame be strong enough to support 10' of drywall? Or do I need a 2x3?
(2) What do I do with the 7"+ gap between the frame and the existing 2x4's? Do I leave it alone, pack with more insulation ???
