INTEGRATING THE WINDOW 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.
I. From the room side of the window, DRILL
clearance holes through the head, jambs and sill of the frame.
Space the holes as shown.

J. Place shims at each pre-drilled clearance hole between
the window and the rough opening.
K. Drill 1/8" x 1" deep pilot holes into the shims and rough
opening through the clearance holes in the unit frame.
L. Fasten the window to the
opening
corrosion resistant flat head wood
screws into each of the pre-drilled
clearance holes.
Note: Drive the screws until snug
but DO NOT over-tighten the
screws. DO NOT bend or bow the
unit frame.
M. Reinstall the clad/wood insert and sashes.
A. Apply side flashing tape.
than the frame height of the window. Apply one piece 1/2" onto the
window frame over the nailing fin and onto the water resistive
barrier on each side. The tape should extend 2" above the top of
the window and 2" below the bottom of the window. Press the
tape down firmly while folding down the excess tape at the top
and bottom of the 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 window 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.
