This was a great project! Our customer needed to convert living space BACK to a garage. After demolition of the area, we noticed very poor insulation, if any, on the buffer wall (wall opposite conditioned space) as well as on the ceiling. With 5" of closed cell foam on the ceiling and 2" of closed cell foam on the buffer wall, we were able to completely seal this garage from any air or moisture with incredible R-Values!! Not to mention adding structural integrity to the floors. The customer said, "I can't hear any of the creaks in the floor any longer and I don't need socks!!!"
