I have sheetrocked walls but not many ceilings. I am about to do my new shop ceiling. I plan to use 12 x 4 x 5/8" sheetrock. The ceiling is currently is trusses on 24" centers (the space is 11.5' x 26'). My question is can I just screw to the trusses and edges (I installed 2x4s around the edge to screw into)? Or do I need to install blocking between the trusses or fir strips to the trusses?
Thanks in advance for your help, you guys (and gals) are always great.
