JELD-WEN JII024 Wood/Clad Wood Windows with Exterior Trim or Nail Fin - Manual

INSTALLATION INSTRUCTIONS
for Wood/Clad Wood Windows with Exterior Trim or Nail Fin (JII024)
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 integrates the window with the weather
barrier of the structure (typically building wrap).
Thank you for selecting JELD-WEN products. Attached are
JELD-WEN’s recommended installation instructions for metal clad
wood windows with nailing fin or primed wood windows with
exterior trim. While the use of these installation instructions
is recommended, installation in strict compliance with AAMA
specifications (2400-02) is an alternate method of installation and
will not affect the JELD-WEN limited warranty.
Not all window types may be installed into every wall condition in all
areas. Consult your local building code official for applicable building
codes and regulations. Local building code requirements supersede
recommended installation instructions.
Please Note! These instructions do not apply to bow and bay windows
and apply only to windows with a horizontal flat sill. Installations
where the sill is higher than 35 feet above ground level, or any product
installation into a wall condition not specifically 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 product warranty as part of the terms of the
sale.

Buck
Sheathed Wall
This installation guide specifically addresses masonry/block wall,
sheathed wall and open-stud construction.
MASONRY/BLOCK WALL CONSTRUCTION
This installation assumes that
a framework of studs (often
called a buck) has already been
properly fastened and sealed to
the concrete/masonry wall by a
building professional.
FULLY SHEATHED WALL CONSTRUCTION
The wall framing is covered by sheathing. Windows will be mounted
flush against the sheathing. This installation assumes building wrap is
properly installed prior to installation.
OPEN-STUD CONSTRUCTION
The wall framing must be
covered by backing support
before the window can be
installed. The window will be
mounted with the nailing fin/
exterior trim flush against the
applied backing support.
This backing support should be a
non water-degradable, thin (max.
1/8" thick) sheet material such
as vinyl sheeting. Completely
surround the rough opening with
the backing support. Backing support must be applied before building
wrap.
