Stepped Foundation Metal Flashing Detail with Exterior Rigid Foam
I am replacing my existing siding and I am doing the following -stud - 5/8" plywood - 1-1/2" of Polyisol, 3/8", WRB, rain screen, fiber cement siding. The house is in the San Francisco bay area on a hill with a stepped foundation.
I plan on putting a galvanized metal flashing were the bottom of the plywood meets the foundation (the rigid foam board will be slightly above the metal flashing). I have read numerous articles on this in regards to a horizontal run, but have not found one with details for a stepped foundation. I am assuming that the metal flashing should also run vertically. Should the metal flashing extend beyond the bottom of the fiber cement siding, or just up to it, or just before it? Have any of you had experience with this detail? Any suggestions?
