JELD-WEN JII032 Wood Bay or Bow Windows with Nailing Fin or Exterior Trim - Manual

INSTALLATION INSTRUCTIONS
for Wood Bay or Bow Windows with Nailing Fin
or Exterior Trim (JII032)
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.
GLOSSARY
Backer Rod (backing material)
A material (e.g. foam rod), placed into a joint primarily to control the
depth of the sealant.
Buck
A wood framework attached to the masonry inside a window or patio
door rough opening.
Mulled Unit
Two or more window units structurally joined together.
Mull Joint
The joint where two or more window units are structurally joined
together.
Precast Sill
A pre-formed concrete block placed in the sill of a masonry/block wall
to support a window.
Shiplap
The layering method in which each layer overlaps the layer below it so
that water runs down the outside.
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 seals the window with the weather barrier
(typically building wrap).
Thank you for selecting JELD-WEN products. Attached are JELD-WEN’s
recommended installation instructions for wood and clad wood
bay and bow windows. 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. 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 official for applicable building
codes and regulations. Local building code requirements supersede
recommended installation instructions.
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 warranty as part of the terms of the sale.

and seat board must be placed on a structure that provides continuous
support to the sill.
MASONRY/BLOCK WALL CONSTRUCTION

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.
