Capping the thermal barrier and insulating behind the roof

This cold weather has encouraged us to hurry up and complete the insulation and waterproofing by capping the 4' thermal barrier with plastic and 4.5" of ISO foam insulation board.

Then we extended the insulation board up behind the roof overhang. Before today, a thin 60 mil layer of EPDM was the only thing between us and the freezing cold; so, the insulation board is a welcome addition.
