A. Apply side flashing tape. Cut two pieces of flashing tape
4" longer than the frame height of the door. Apply one
piece 1/2" onto the frame cladding, over the nailing fin
and onto the water resistive barrier. The tape should extend
2" above the top of the door and 2" below the bottom of
the door. Press the tape down firmly while folding down
the excess tape at the top and bottom of the door.
B. Apply top flashing tape. Cut a piece of flashing tape long
enough to go across the top of the door and extend at least
1" past the side flashing tape on both sides. Apply the tape
1/2" onto the frame cladding, over the top nailing fin as
shown. Fold the overlapping tape down, and press all tape
down firmly.
Note: The top flashing tape must overlap the
side flashing tape to prevent water from getting
behind it.
C. Fold down top flap
of water resistive barrier (3C).

INTEGRATING THE DOOR TO THE
WATER RESISTIVE BARRIER
Note: The flashing tape must be applied approximately 1/2"
onto the frame cladding at the jambs and head. Pre-folding the
tape at 1/2" before removing the paper backing will make it
easier to apply the tape correctly. If the siding is less than 1/2"
thick, adjust the dimension of the fold so the exterior sealant
line will cover the exterior edge of the tape.
D. Apply flashing tape to diagonal cuts. Cut pieces of
flashing tape at least 1" longer than the diagonal cuts
in the water resistive barrier. Apply the tape covering
the entire diagonal cut in the water resistive barrier
at both upper corners of the door.
Note: Be sure to overlap the top corners (3D).
