Note: The flashing tape may not fully cover the framing
members.
SETTING AND FASTENING THE WINDOW
A. Install and level sill spacers. Place 1" wide by 3/8" thick spacers
on the bottom of the window opening 1/2" from each side.
Spacers are also required at points where windows are joined in
multiple window applications. Add shims as necessary to ensure
the spacers are level. Once level, attach spacers and shims to
prevent movement.
2A
Note: Improper placement of shims or spacers may result in
bowing the bottom of the window.
B. Remove plastic wrap and cardboard packaging from window. DO NOT remove plastic
shipping spacers located between the window sash and frame. The shipping spacers will
help keep the window square during installation. DO NOT unlock or open the window
until it is fully fastened.
Note: If screens, grilles or hardware are removed from the window at this time, label
them and store them in a protected area.
C. Fold out installation fin to 90°. Be careful not to remove or
tear the fin corners.
2C
Note: If the fin is not at 90°, the window will not line up
correctly on the interior.
D. Curved Units with Fins:
Curved Units with frame radius > 12" will be provided with fixed fin.
On windows with fixed extruded fin, drill 1/8" diameter holes in the fin every 12".

Installation Clips for Structural Support:
Determine installation clip placement. Clips
(provided) should be evenly spaced across the curved
frame member and no more than 16" on center.
Place the clips so the lip is facing up and against the
instillation fin. Secure each clip by driving a #6 x 5/8"
corrosion resistant screws through the outer two holes
of the three holes shown.

TWO OR MORE PEOPLE WILL BE REQUIRED FOR THE
FOLLOWING STEPS.
2E
E. Insert the window from the exterior of the building. Place
the bottom of the window on the spacers at the bottom of the
opening, then tilt the top into position. Center the window
between the sides of the opening to allow clearance for
shimming, and insert one roofing nail in the first hole from
the corner on each end of the top nailing fin. These are used
to hold the window in place while shimming it plumb and
square.

2F
F. Plumb and square window. Place shims 1" from
the bottom and top of the window between the
window and the sides of the opening. Adjust
the shims as required to plumb and square the
window in the opening. If the frame height
exceeds 53", place shims at the midpoint of the
window sides.
2F
Note: Do not shim above the window or in the
space between the spacers at the bottom of the
window. DO NOT over shim.

H. Check window operation (vent units only). Unlock the window by
lifting the lock handle up. Open the window by rotating the crank
handle. Remove the shipping spacers. Open and close the window a few
times to check for proper operation. Close and lock the window.
Note: If there are any problems with the operation of the window,
recheck shim locations and adjust for plumb and square.
I. Fasten the window to opening by driving 2" galvanized roofing
nails into each pre-punched hole in the nailing fin.
Note: Make sure the fin corner is lying as flat as possible.
2I
J. For units with flexible non-structural curved fin on which
clips were added: Fasten the clips to the opening by driving
two #6 x 1-1/2" or longer corrosion resistant into the pre-
punched holes in the clips. If clips are bent and fastened to the
interior stud, install the screws as close to the bend as possible.
2J
Note: DO NOT shim above the window.
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.

Flashing
Tape
Rectangular Units Only:
A. Apply side flashing tape. Cut two pieces of flashing tape
4" longer than the frame height of the window. Apply
one piece to each side 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 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.
3B
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
3B
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.

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.
3D
Note: Be sure to overlap the top corners (3D).
Curve Top and Angle Top Units Only:
A. Units that do not have pre-applied fin corners:
Cut four pieces of flashing tape 1-1/2" long. Apply
3A
one piece of flashing tape to each end of the sill fin
so that it extends 1-1/2" past the end of the sill fin.
1st
Apply one piece of flashing tape to the bottom end
of each flexible fin, beginning 1-1/2" from the end
of the fin and lapping over the flashing tape that
extends from the end of the sill fin.
3A
2nd
B. For Curve Top Windows: Several pieces of flashing tape will
be needed to cover the top fin. Start taping from the sides
of the window working toward the peak. To determine the
length of cuts, hold the tape along the radius, and cut the
tape just past where it leaves the top
fixed extruded fin or for the flexible
3B
fin, just past the flexible weather
strip. The top tape must overlap the
one beneath it in order to divert
water properly. The sharper the arc
of the window, the shorter the pieces
of tape will be.
3C
Exterior
C. Apply top flashing tape to an angle top
window 1/2" up onto the frame cladding,
over the top fin onto the sheathing. On
3C
the short side of a trapezoid window, do not
allow the side flashing tape to extend higher
than what the top tape will cover. Fold the
overlapping tape down, and press all tape
down firmly.

INTERIOR SEAL
4
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.
4A
Interior
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 of the foam and will minimize
squeeze out. If using foam other than Great Stuff ™ 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.
SEALING THE WINDOW TO THE EXTERIOR
WALL CLADDING
When applying siding, brick veneer or other exterior finish material, leave adequate space
between the window frame and the material for sealant. Refer to the illustration that
corresponds to your finish material.
