Contrast plywood window RO extensions with other method?
I wonder if I could get some discussion on the pros and cons of two window methods with outsulation.
I’ve seen the plywood RO extenders used.
Contrast that with:
(for a 2 in exterior detail) 1 layer of foam right to window RO, with the RO then surrounded with 1x 3+/- as an attachment surface for the window flange. Second inch of foam buts up to the wood around the RO.
Similar situation for thicker foam I suppose.
