INSTALLATION INSTRUCTIONS
for Vinyl Windows with Integral Nailing Fin (JII001)
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 Vinyl windows with an integral
nailing n. While the use of these installation instructions is recommended,
installation in strict compliance with AAMA specications (2400-02) is an
alternate method of window installation. Use of the AAMA specications
(2400-02) will not affect application of 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! 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.
