IMPORTANT INFORMATION AND GLOSSARY

INSTALLATION INSTRUCTIONS

for Wood/Clad Wood Windows without Exterior Trim or Nailing Fin (JII025)

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.

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.

Not all window types may be installed into every wall condition in all areas. Consult your local building code ofcial for applicable building codes and regulations. Local building code requirements supersede recommended installation instructions.

Please Note! This installation guide specically 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 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 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.

REMOVE PACKAGING

Remove shipping materials such as corner covers, shipping blocks or pads. If there is a protective lm on the glass, do not remove it until installation and construction are complete. Cut off any staple legs exposed on the side of the frame.

Note! Double-hung windows may have banding on the interior of the

unit. Do not remove until the window is secured in the opening to help keep the sash in place and the unit square.

• Verify the width and height of the window are each 1/2"-5/8" smaller than the rough opening width and height. Mulled units should be 3/4" narrower.

• Verify the rough opening is square. The (A) and (B) measurements above should be the same. Maximum allowable deviation from square is 1/8" for windows 20 sq. ft. and smaller, and 1/4" for windows larger than 20 sq. ft.

REMOVE PACKAGING AND INSPECT WINDOW

INSPECT ROUGH OPENING

Verify Square, Level, & Plumb

INSPECT WINDOW

• Cosmetic damage

• Product squareness (diagonal measurements not more than 1/4" different)

• Correct product (size, color, grid pattern, handing, glazing, energyefciency requirements, etc.)

• Drip cap that extends the length of the clad trim plus 1/8" overhang on each end (all units require a drip cap); drip cap may or may not be pre-installed

If any of the above conditions represent a concern, or if you expect environmental conditions to exceed the window’s performance rating, do not install the window. Contact your dealer or distributor for recommendations.

• Verify the rough opening is level and plumb (C) and (D). The maximum allowable deviation is 1/16" for every 2' of rough opening (not to exceed 1/8").

• The rough opening sill must not be crowned or sagged (D). A 5 degree sloped sill is recommended.

• The exterior face of the rough opening must be in a single plane (E) with less than 1/8" twist from corner to corner.

• Minimum double studs (king and jack/trimmer) should be used to support the header at all wood framed rough openings.

Note! This section applies to

installations into a masonry wall only. For installations into a stud-framed wall, begin with section 4, “PREPARE STUDFRAMED WALL.”

1. Seal any joint larger than 1/16" in the buck and between the buck and the concrete/masonry with sealant.
