Installation Instructions
for Vinyl Windows without Nailing Fin (JII011)
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.
Thank you for selecting JELD-WEN products. Attached are
JELD-WEN’s recommended installation instructions for Vinyl Windows
without a Nailing Fin (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. Areas such as Florida and
the Texas TDI region have different anchoring requirements based
on product certication. For information on specic 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.
