3 INTEGRATING THE WINDOW TO THE WATER RESISTIVE BARRIER
A. Apply side flashing tape. Cut two pieces of flashing
tape4"longerthantheframeheightofthewindow.

window.
B. Apply top flashing tape. Cut a piece of flashing tape
long enough to go across the top of the window and
extendatleast1"pastthesideflashingtapeonboth
sides.Applythetape1/2"ontotheframe,overthe
top nailing fin as shown. Fold the overlapping tape
down, and press all tape down firmly.
Note: DO NOT tape or seal the bottom nailing fin.
C. Fold down top flap of the water resistive barrier.
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 window.
Note: Be sure to overlap the top corners.
4 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 window 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 window and the rough opening and apply
a1"deepbeadoffoam.Thiswillallowroomforexpansion

Window and Door Insulation Foam
Sealant by the Dow Chemical Company, allow the foam to
drycompletely(usually8to24hours)beforeproceedingto
thenextstep.
Note: DO NOT completely fill the space from the back of
the fin to the interior face of the opening.
B. Check window operation(ventunitsonly)byopeningandclosingthewindow.
Note: If the window does not operate correctly, check to make sure it is still plumb, level,
square and that the sides are not bowed. If adjustments are required, remove the foam
with a serrated knife. Adjust the shims, and reapply the insulating foam sealant.
