Finishing rigid foam against an innie window
So I read the innie vs. outie window article on GBA and decided to go with the innie route as I had already made my R/O to size and didn't have time to fir out the windows before my window installer (friend) showed up. So I have my windows in with flanges against sheathing and they stick out just over 2" from the sheathing. I am putting 2' rigid polyiso on the exterior and butting it into the windows. This means there is no foam showing. Do I need to put peel and stick flashing on the exposed foam before installing it? should I leave it away from the window slightly and spray foam that gap? Wondering what the flashing detail will be. I will then put 3/4" vertical strapping and then siding. I have put my WRB against my sheathing. The polyiso is fiberglass faced not foil faced. Thanks in advance.
