INSTALLATION INSTRUCTIONS
for Vinyl Windows without Nailing Fin (JII011)

Flush Fin Window

A window without a nailing fin that has a face flange (trim only). Flush

fin windows may also be known as flange, stucco flange or Florida

flange windows.

Head Expander

A vinyl accessory used to cover the head of the window in some

retrofit applications.

Installation Clip

A vinyl accessory that snaps into the accessory groove of some fixed

windows, used to secure the window to the rough opening.

Precast Sill

A pre-formed concrete block placed in 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.

Sill Adapter

A replacement frame component attached to the sill of a finless

window being installed into an existing window frame with a sloped

sill. The component cancels out the sloped sill of the existing double-

hung, helping to support the front edge of the window sill.

Stop

The trim pieces on the frame that retain the sashes.

Weep Hole (weep channel)

The visible exit or entry part of a water drainage system used to direct

and drain water out of a window.

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 finless, flush fin and flange). 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.

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 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.
