Looking for diagram showing how to detail felt or housewrap under 1.5″ foil faced foam with window sill extension
Hi, Hoping you can direct me to a good diagram showing how to detail wall and outie flanged window particularly for exterior foam insulation. We are set to begin within a few days and I am worried it won’t be done correctly. It is 2×6 wall 24″oc with 2×8 window box extension. The 1 1/2 foam will go over osb covered with #15felt (OK?) Vinyl siding (no furring?). We are in climate zone 5. I have poured over 100’s of articles and cannot seem to find how to detail the felt (or other product) correctly when the window is built out. The foil face foam will be drainage plane and flashing should be covered over that if I am following everything correctly. Can you assist please?
