One reader asked a question about installing the doors with the exterior insulation, the Roxul mineral wool Comfortboard. Here's the question:
Hello, wanted to say great job on the house!
Im currently gutting a 1930's bungalow down to the frame & sheathing & am planning to add roxul comfortboard to the exterior. I see you went with the approach of mounting the doors and windows to the outside of the now-thicker walls. The windows are easy, but I'd like to see or hear about how you did the doors. Did you fir out the door opening, mount the door to the outside of the thicker wall, then trim the difference inside? If so, does this stop the door from swinging open fully? Thanks for any input on this detail....there is so little info online about the door installs on these exterior insulation jobs.
From looking at the photos the doors were installed on the outside of the thicker wall and trimmed out on the interior. It probably does prevent the door from opening more than 90 degrees. Here are some photos that might help explain it better than I could.

This is an article in Fine Homebuilding where they address your question when double stud walls are used:
