Because of moisture entrapment, I need to rebuild the outer portion of a wall. Originally a stucco on durock on WRB, on plywood sheathing, It is being replaced with Hardie plank on furring on Roxul rigid IS on WRB on plywood. This means the windows will end up being inset...and flashing will have to be installed at the sill, jamb and head. I'm concerned about the sill specially... how to handle the ends of it where it butts up to the jamb. I would appreciate creative ideas about how to handle this intersection specially...Also I'm open to any ideas for the head and jamb . here is a link to details I have come up with..
