Installation Instructions
for Vinyl Windows with Integral Nailing Fin (JII001)
3
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.
4. Place shims on the buck 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.
• One shim placed 3/4" to
1" in from each side wall of
thebuck.
• 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. SKIP to section 5,
“INSTALL WINDOW.”
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.
Inspect Window
• Cosmetic damage.
• Product squareness (diagonal measurements not more than
1/4"different).
• Correct product (size, color, grid pattern, handing, glazing, energy-
efciency requirements, etc.).
• 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 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.
• Verify the rough opening is level and plumb (C, D and E). The maximum
allowable deviation is 1/16" for every 2' of rough opening (not to
exceed 1/8").
• Cracked frame welds or other frame damage.
• Splits, cracks, holes, missing sections or other damage to the nailing n
longer than 6" and/or within 1/2" of window frame.
• For side-by-side mulled units, a drip cap that extends the length of the
frame plus 1/8" overhang on each end is required.
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.
• 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 Retrot 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.
