I recently remodeled the second story of my cape and used both EPS  and Polyiso... over the studs/joists before the drywall went up.
I now wish to add some insulation to the exterior of a small addition. The addition was built several yrs ago and has fiberglass/ 4mil poly vapor barrier inside. checking the info on buildingscience.com I am now concerned that the vapor barrier could cause problems if I do add a layer rigid foamboard to the exterior. Any thoughts? Fine Homebuilding has an article on this but I need more confirmation.
Also anyone have any troubles with building inspectors requiring the use of house wrap even though foamboard sheds water?
