Prepare Stud-Framed Wall
Prepare Building Wrap:
Trim building wrap ush with
the edges of the rough opening
(or follow manufacturer’s
instructions for trimming).
Prepare/Shim the Sill:
1. Use self-adhered ashing to
waterproof the sill.
2. Flashing must have at least 2"
of material wrapped below
the sill onto the vertical wall.
Flashing width must be at least
frame width + 1".
3. Measure the width of the
frame and subtract 1/4".
Transfer this measurement
from the outside edge of the
rough opening sill and draw
a line all along the rough
opening sill. This is where the
back of the ashing will sit.
4. Cut a piece of ashing the
length of the sill plus 12".
5. Place ashing on rough
opening sill, wrapping the
ashing up 6" on each jamb
asshown.
6. Pull release tape and set
ashing into place.
7. Fold the ashing down onto the sheathing. Staple ashing to the wall, if
needed, and seal the corner edges as shown.
8. Smooth out any bubbles or creases with a J-roller.
9. Place shims on the rough
sill as needed to level the
window and prevent sagging
or bowing. Shims should
be aligned in the following
fashion:
• Near the exterior edge of
the sill.
• 1 shim placed 3/4" to 1" in
from each side wall of the rough opening.
• No more than 24 inches on center between additional shims.
• For mulled units ensure there is a shim located 1/2" either side of the
mull joint.
Shims may be temporary held in place with sealant.

Prepare Existing Window Frame
1. Remove the sashes and/or glass
in the existingwindow.
2. Remove all hardware and
window components not a
part of the frame (meeting
stile, jamb liners, locking
mechanisms or other
hardwareetc.).
If Installing into an Aluminum
Window Frame:
1. Seal all four corners of the
window frame asshown.
2. Notch grooves across the
bottom of the continuous
support (see materials list)
to allow for water drainage
through the weep holes. Set
the continuous support into
the exterior sill track, creating a
level surface at the sill.
SKIP to section 4,
“INSTALLWINDOW.”
If Installing into a Wood Window Frame:
1a. If installing from the interior,
remove any trim on the inside
face of the wood frame. Do
not remove the exteriorstops.

remove any trim on the
outside face of the wood
frame. Do not remove the
interiorstops.
NOTE: Steps 2 and 3 are not applicable if installing into an existing
double-hung with sloped sill.
2. Place shims on the window sill as needed to level the window
and prevent sagging or bowing. Shims should be aligned in the
followingfashion:
• Near the exterior edge of the sill.
• 1 shim placed 3/4" to 1" in from each side wall of the window frame.
• No more than 24 inches on center between additional shims.
• For mulled units ensure there is a shim located 1/2" either side of the
mull joint.
Shims may be temporary held in place with sealant.

Prepare Masonry Opening with Buck
1. Seal any joint larger than 1/16" in the buck and between the buck and
the concrete/masonry withsealant.
2. Cover the buck and the surrounding concrete/masonry at the head and
jambs with liquid applied
ashing asshown.
3. If installing into a four-
sided buck, seal the sill in a
similarmanner.
4. Place shims on the buck
sill as needed to level
