Thank you for selecting JELD-WEN products. Attached are JELD-WEN’s
recommended installation instructions for vinyl 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, however, approved methods will not typically
affect warranty coverage. See the appropriate warranty for details.
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 house, 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 official for applicable building
codes and regulations. Local building code requirements supersede
recommended installation instructions. Areas such as Florida and the
Texas TDI region have different anchoring requirements based on
product certification. For information on specific products, visit
www.floridabuilding.org or www.tdi.texas.gov and follow the
anchoring schedule given in the drawings for the product instead of
the anchoring schedule in this document.
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.
