I love these doors ! One opens out,...and the other opens in ! How cool is that !? The thing is there is only an interior cover for them which means my R value for insulating will be down. Any ideas on how to make these doors air tight along this hinge from top to bottom ? Should I also make covers for the outside to help ? The doors are part of this sweetheart and to think of taking them out and putting a regular door in screams taking value from its age and character. Any advice would help. Thanx guys ! Cheerz !
