Where does the flashing sit? above or below the isoline sheet?
  1. The flashing piece is OVERLAID onto the bottom and side of the ISOLINE® sheet.
  2. The top ISOLINE® sheet (the one above the penetration) is then OVERLAPPED onto the flashing piece.

This layered approach ensures that water shedding off the top sheet runs onto the flashing, which then directs the water over the bottom or side sheet, maintaining the system's waterproof integrity.
