INTEGRATING THE DOOR TO THE
WATER RESISTIVE BARRIER
A. Apply the side flashing tape. Cut two pieces of flashing
tape 4" longer than the frame height of the door. Apply
one piece to each side 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.
B. Apply the 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 over the top nailing fin as
shown. Press the tape down firmly.
Note: The tape should cover the
entire nailing fin, but not extend
onto the door frame. The top flashing tape
must overlap the side flashing tape to prevent water
from getting behind it.
C. fold down the top flap of the water resistive barrier.
D. Apply flashing tape to the 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. Press the tape down firmly.
Note: Be sure to overlap the top corners.
E. Attach the wood blocking or aluminum sill support to the
exterior of the opening to support the edge of the door sill.

INTERIOR SEAL
Caution: Ensure use of low pressure polyurethane window and door insulating foams
and strictly follow the foam manufacturer's recommendations for application. Use of
high pressure foams or improper application of the foam may cause the door frame to
bow and hinder operation.
A. Apply insulating foam sealant. From the interior, insert
the nozzle of the applicator approximately 1" deep into
the space between the door and the rough opening and
apply a 1" deep bead of foam. This will allow room for
expansion of the foam and will minimize squeeze out. If
using foam other than Great Stuff™ Window and Door
Insulating Foam Sealant by the Dow Chemical Company,
allow the foam to cure completely (usually 8 to 24 hours)
before proceeding to the next step.
Note: It may be necessary to squeeze the end of the
tube with pliers to be able to insert into the space
between the door frame and the rough opening. DO
NOT completely fill the space from the back of the fin
to the interior face of the door.
