Double hung exterior doors in same RO ??
Anyone seen or heard of an in-swing and out-swing exterior door hung in the same rough opening for increased insulation. I have 9" thick wall depth to work with. Energy efficient(HI-R) doors are hard to find and extremely costly for the ones I have found. Only problem I can foresee is possible frosting between doors if in door seal leaks, or thru lock sets.
