REMOVE PACKAGING
Remove shipping materials such as corner covers, shipping blocks or
pads. If there is a protective lm on the glass, do not remove it until
installation and construction are complete. Cut off any staple legs
exposed on the side of the frame.
Note! Double-hung windows may have banding on the interior of the
unit. Do not remove until the window is secured in the opening to help
keep the sash in place and the unit square.
INSPECT WINDOW
• Cosmetic damage
• Product squareness (diagonal measurements not more than
1/4"different).
• Verify the width and height
of the window are each
1/2"-5/8" smaller than the
rough opening width and
height. Mulled units should
be 3/4" narrower.
• Verify the rough opening
is square. The (A) and (B)
measurements above should
be the same. Maximum
allowable deviation from
square is 1/8" for windows
20 sq. ft. and smaller, and
1/4" for windows larger than
20 sq. ft.
• Correct product (size, color, grid pattern, handing, glazing, energy-
efciency requirements, etc.).
• Drip cap that extends the length of the exterior trim plus 1/8"
overhang on each end (all units require a drip cap); drip cap may or
may not be pre-installed.
• Splits, cracks, holes, missing sections or other damage to the nailing
n longer than 6" and/or within 1/2" of window frame.
If any of the above conditions represent a concern, or if you expect
environmental conditions to exceed the window's performance
rating, do not install the window. Contact your dealer or distributor
forrecommendations.
• Verify the rough opening is plumb and level (C, E) and (D). The
maximum allowable deviation is 1/16" for every 2' of rough opening
(not to exceed 1/8").
• The rough opening sill must not be crowned or sagged (D), but rather
level or sloped (positive slope) to the exterior.
• The exterior face of the rough opening must be in a single plane (E)
with less than 1/8" twist from corner to corner.
• Minimum double studs (king and jack/trimmer) should be used to
support the header at all rough openings.
FOR RETROFIT INSTALLATIONS
After removing the old window, remove sufcient cladding (siding,
stucco etc.) to expose enough intact building wrap to properly seal
the window to the opening. If damaged, apply new building wrap in
shiplap manner. Verify the rough opening framing is structurally sound.
Contact your local waste management entities for proper disposal or
recycling of products being removed.
Note! This section applies to
installations into a masonry
wall only. For installations into
a stud-framed wall, begin with
section 4, “PREPARE STUD-
FRAMED WALL.”
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.
Note! Where the window will sit on the sill, shim to provide continuous
support to the sill. This shimming must be a minimum of the width of
the window frame and a minimum of 1/4" narrower than the depth of
the window frame sill, should level the rough opening sill and be no
more than 1/4" thick.
4. Align the shimming on the sill ush with the exterior and centered
between the side jambs. If installing a mulled unit, shim under
the mull joint(s) and tack into place or secure with sealant. SKIP to
section 5, “PREPARE WINDOW.”
