Hi All, I'm going to build a small room in my garage to do wood working and put in a small a/c unit. It's going to be about 10' x 15' and I'm using 2x4's construction with walls and ceiling insulated. My question is what wall material would you use? I'm trying to decide between OSB (oriented strand board) and drywall. I think I would just paint the drywall but no taping/mudding etc. For the OSB I would just prime and paint also. I'm thinking the drywall would cut easier than OSB. Which do you think you'd go with? Thanks!
