I am re-finishing my attic which has a cathedral ceiling. The attic ceiling used to have wood panelling applied over 1x3 strapping. I took down the panelling and want to apply 1/2" drywall it its place. The ceiling rafters are really crooked (as much as 1 inch difference from one rafter to the next), so I *think* I need to use *some sort of strapping*.
A) Should I leave the 1x3 strapping and shim the strapping level to prepare for the 1/2" drywall? (The strapping is not shimmed at all right now). I suspect this would take a-lot of work, and I am not sure how to do it.
B) Or should I take down the 1x3 strapping, and apply 2x2 strapping in its place. The 2x2 strapping would simply be 2x4's ripped in half. I suspect this method would be much easier as the 2x2's will be much stiffer.
C) In either case, should I screw or nail up the strapping? Thanks!!!
