I need some help guys! lol..So we have a converted garage but in the first room which we use as a laundry/micro kitchen it has exposed unfinished ceiling. The other room separated by a door is the bedroom and bathroom and it is finished with a window unit AC. We are in Florida and that first room gets soooo hot. Does anyone have any suggestions for a easy/cheapest solution to keep the exposed beams but still insulate to cut down on the heat. Thank yoU!
