    Hi Jerry,

    §13-606.1.ABC.1.2 Exterior Joints or Openings in the Envelope. Exterior joints, cracks, or openings in the building envelope that are sources of air leakage shall be caulked gasketed, weather stripped or otherwise sealed in accordance with the criteria in §13-606.1.ABC.1.2.1 through §13-606.1.ABC.1.2.5.

    Hi Richard,

    I would apply all of the following sections are they each potentially cover various aspect of the installation.

    - - - R703.8 Flashing.
    - - - - Approved corrosion-resistive flashing shall be provided in the exterior wall envelope in such a manner as to prevent entry of water into the wall cavity or penetration of water to the building structural framing components. The flashing shall extend to the surface of the exterior wall finish and shall be installed to prevent water from reentering the exterior wall envelope. Approved corrosion-resistant flashings shall be installed at, but not limited to, all of the following locations:
    - - - - - 1. Flashing for windows and doors shall be in accordance with Section R613.8.
