Prepare/Shim the Sill
1. Install a sill pan in a
weatherproof manner on
the rough sill (refer to ASTM
2112 for types of sill pans).
Always allow water to drain
out of the pan and onto
the building wrap, drainage
plane or to the exterior.
NOTE: If using a rigid sill
pan, apply a continuous
bead of sealant to the
interior of the upturned leg
of the sill pan.
2. Apply a continuous bead of
sealant to the interior of the
upturned leg of the sill pan
(if using a rigid sillpan).
1. 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.
• Steps may not pertain to existing aluminum frames or sloped sill.
NOTE: For large, heavy or mulled units, shim at 8" on-center
and no more than 2" from each corner to maintain proper sill
alignment. This shimming schedule also pertains to regions where
the ambient air temperature reaches or exceeds 95°F (35°C).
Prepare Existing Window Frame (Aluminum 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.).
3. Seal all four corners of the
window frame asshown.
4. 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.
WARNING! To avoid injury, use at least two people to install.
Adequately support the window until completely fastened.
Installation Clips: If installation clips are to be used, reference Section 5
for proper clip application prior to setting the window.
Existing Window Frame: If installing into an existing window frame with
a sloped sill, reference Section 5 for proper stop-in application prior to
setting the window.
Through Frame Fastening: If installing by placing screws through the
main window frame begin by shimming the product in place using the
steps below.
• Place shims 4"- 6" from each corner on the side and head jambs.
Evaluate the window position with the opening for plumb, level, square
and twist (Reference the Product Installation Tolerance Table).
• Place the shims at the interlock
of hung windows or in the
center for all other windows.
NOTE: Some hung windows
have a “jamb jack” along each
side. Engage the #8 x 2" at
head screw until the rst click
is heard and then adjust the
side jamb as needed, prior to
adding shims.
