IMPORTANT INFORMATION AND GLOSSARY
INSTALLATION INSTRUCTIONS
for Aluminum Windows without Nailing Fin (JII031)
Thank you for selecting JELD-WEN products. Attached are
JELD-WEN’s recommended installation instructions for aluminum
windows without a nailing n (including nless, ush n and
ange). Read these instructions thoroughly before beginning.
They are designed to work in most existing applications, however;
existing conditions may require changes to these instructions.
If changes are needed, they are made at the installer’s risk. For
installations other than indicated in these instructions, contact a
building professional.
Newer construction methods have led to an increase in air and water
tightness in buildings. This frequently leads to negative air pressure
inside the home, which can draw water through very small openings.
Our installation method creates an air seal on the interior, integrating
the window with the rough opening.
Not all window types may be installed into every wall condition in all
areas. Consult your local building code ofcial for applicable building
codes and regulations. Local building code requirements supersede
recommended installation instructions.
Note! Installations where the sill is higher than 35 feet above ground
level, or any product installation into a wall condition not specically
addressed in these instructions, must be designed by an architect or
structural engineer.
Failure to install windows into square, level, and plumb openings could
result in denial of warranty claims for operational or performance
problems.
Note to Installer: Provide a copy of these instructions to the building
owner. By installing this product, you acknowledge the terms and
conditions of the limited warranty as part of the terms of the sale.

FOR RETROFIT INSTALLATIONS
After removing the old window,
remove sufcient siding 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. Continue
with the instructions.
PREPARE BUILDING WRAP
Note! Check with the building wrap manufacturer to verify the
following steps will not void their product warranty. Follow
manufacturers' instructions.
1. Trim building wrap ush with
the rough opening.
2. At the head, cut building
wrap at 45° and tape up as
shown.
3. Trim the sides sufciently
to allow the nailing n to
be mounted against the
sheathing.
PREPARE STUD-FRAMED WALL
45°
PREPARE SILL
1. Use self adhesive ashing to waterproof the sill.
2. Flashing must have at least 2"
of visible material below nail
n. Flashing width must be at
least frame width + 1 3/4".
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 and seal the corner
edges as shown.
8. Smooth out any bubbles or
creases with a J-roller.
9. Install the continuous shim as
follows:
Note! The continuous shim
must be 1/2" shorter than the width of the window frame, be 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.
Align the shim on the sill ush
with the exterior and centered
between the side jambs. If
installing a mulled unit, leave
gaps at the mull joint(s) so
they don't sit on the shim and
tack into place or secure with
sealant.
