We at DFI had the pleasure of working for this very nice couple in the Sunday River area. We applied 6" R 42 Bayer closed cell foam underneath the roof deck of there home and 3" R 21 to the gable ends. After deciding they were going to finish of the second floor, they wanted to make the upstairs as energy efficient as possible. Not only a pleasure to work for, they make some of the best chocolate chip cookies around.
