How to block and insulate the space between bottom of the roof sheathing and the top plate?
My attic has twelve inch rafters that are notched out and sit on a top plate. There are large air gaps between the bottom of the roof sheathing and the top plate. What is the correct, and by code, to seal off these gaps? Currently my insulation contractor has these areas blocked off with rigid foam and air sealed appropriately.
Please see attached pics. The pic of the home is my home showing the area in question blocked off with the rigid foam board.
