Vinyl Flush Fin Windows
Product Information
The product described in the user manual is a vinyl window,
available in two types: Vinyl Flush Fin Windows and Vinyl Windows
with Nailing Fin. The flush fin window is designed for retro-fit
installation into an existing window frame with a 3/8 or wider
return that protrudes past or is flush with the exterior siding.
The window is sealed to this surface, and there should be no fins
or lips extending beyond this vertical plane. The vinyl window with
a nailing fin incorporates an integral nail fin for
installation.
The installation instructions provided are recommended by
JELD-WEN but do not supersede any national, provincial, or local
building codes. In Canada, installation in strict compliance with
CSA A440-4 is considered an alternate method and does not affect
the JELD-WEN limited warranty. The instructions also mention that
newer construction methods have increased air and water tightness
in buildings, which can lead to negative air pressure inside the
home and draw water through small openings. The installation method
integrates the window with the weather barrier, typically building
wrap.
Product Usage Instructions
Vinyl Flush Fin Windows
Before installing Vinyl Flush Fin Windows, ensure the following
prerequisites are met:
- Drywall return
- Exterior siding
- No extending fins or lips
- Weep hole
- Minimum 3/8 return
If the existing window frame does not have a sufficient return,
consult an installation professional to design an installation that
completely seals the new window in a weatherproof manner.
Important information to note:
- This installation assumes that the existing frame has a
water-tight installation into the structure. - Any local building code requirements take precedence over the
recommended installation instructions. - Failure to install square, level, and plumb could result in
denial of warranty claims for operational or performance
problems. - Installation with the window sill higher than 35 feet above
ground level or into a wall condition not specifically addressed in
the manual must be designed by an architect or structural
engineer.
The estimated installation time for new construction is as
follows:
- First Time: 4 hrs
- Experienced: 3 hrs
- Professional: 2 hrs

window and the existing siding.
Installation Instructions for Vinyl Flush Fin Windows and Vinyl Windows with Nailing Fin
Vinyl Flush Fin Windows Vinyl Windows with Nailing Fin
The flush fin window is a retro-fit product designed for installation into an existing window frame with a 3/8″ or wider return that protrudes past or is flush with the exterior siding. There cannot be any fins or lips that extend past this vertical plane. The flush fin window will be sealed to this surface.
The attached are JELD-WEN’s recommended installation instructions for vinyl windows which incorporate an integral nail fin. These installation instructions do not supersede any national, provincial, or local building codes. While the use of these installation instructions is recommended, in Canada, installation in strict compliance with CSA A440-4 is an alternate method of window installation and will not affect the application of the JELD-WEN limited warranty.
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 weather barrier (typically building wrap).
*These installation instructions do not supercede any national, provincial or local building codes. They are meant as a guideline and reflect good installation practices.
INSTALLATION PREREQUISITES

GLOSSARY
SAFETY & HANDLING
Flush Fin Window: A vinyl window used for retro-fit installation into an existing window frame. The integral exterior trim is decorative and covers the gap between the new window and the existing siding.
Meeting Stile: A vertical frame member of a window that sits in the center of the exterior sill track and either holds one side of the fixed
glass or keeps the stationary sash from moving.
Minimum Opening Width/Height: Measurements taken to determine the size of window that will fit into a retro-fit opening. For example, the minimum opening height is the distance between the highest frame point on the sill to the lowest frame point on the header.
Return: The exterior face of an existing window frame that helps tie the window to the siding.
Mulled Unit: Two or more window units structurally joined together.
Minimum opening height
Header Sill
Shiplap: The layering method in which each layer overlaps the layer below it so that water runs down the outside.
Weep Hole (weep channel): The visible exit or entry part of a water drainage system used to drain water out of a window.

OPEN-STUD INSTALLATION
The wall framing needs to be covered by backing support before the window can be installed. The window will be mounted with the nailing fin 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 as shown. Backing support must be applied before building wrap. Note! For curved windows, ensure framing is sufficient around window perimeter to allow nailing fin to be nailed every 8″ to the framing.
