INSTALLATION INSTRUCTIONS

for Wood/Clad Wood Windows with Exterior Trim or Nail Fin (JII024)

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 of the structure (typically building wrap).

Thank you for selecting JELD-WEN products. Attached are

JELD-WEN’s recommended installation instructions for metal clad

areas. Consult your local building code ofcial for applicable building

codes and regulations. Local building code requirements supersede

recommended installation instructions.

Please Note! 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 specically 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

FULLY SHEATHED WALL CONSTRUCTION

The wall framing is covered by sheathing. Windows will be mounted

ush 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

as vinyl sheeting. Completely

surround the rough opening with

the backing support. Backing support must be applied before building

wrap.
