I have a single outside wall in my garage that I am trying to finish on the inside. I have already installed insulation. The other two walls were finished by the builder with sheetrock. Since this area is used mainly for a catch all or game room it certainly doesn't have to be perfect. I would like to know what is the less expensive way to give a "finished" look to that wall (do not want to hire someone to do sheetrock). I was thinking pressed board or MDF or something of that nature. Also have to do the area above the garage door. I also put insullation on the door. Looks kinda dumb but I think it is keeping it warmer in there. Will hang some sort of covering over that maybe. HELP....
