INSTALLATION INSTRUCTIONS
for Wood/Clad Wood Windows without Exterior Trim
or Nailing Fin (JII025)
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 rough opening
by creating an air seal on the interior with low expanson foam.
Thank you for selecting JELD-WEN products. Attached are
JELD-WEN’s recommended installation instructions for metal clad
wood windows without nailing n or primed wood windows
without exterior trim. Read these installation 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.
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.
Please Note! This installation guide specically addresses installation
into block/masonry wall, sheathed wall and open-stud wall
construction. These instructions do not apply to bow and bay
windows and apply only to windows with a horizontal at sill.
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 product warranty as part of the terms of
the sale.
