JELD-WEN exterior window and door products should be installed in
accordance with JELD-WEN’s recommended installation instructions,
which are printed on the product label or can be found on our
website: www.jeld-wen.com. NOTE: When using ashing, spray
adhesive/primer, sealant and foam products, we recommend using
the same manufacturer and verifying compatibility. It is the End User’s
responsibility to determine if dissimilar materials are compatible with
the substrates in the application.
• Sealant: An exterior grade (High-Performing, Low VOC) sealant
is recommended for installation practices. Check with sealant
manufacturer for color-match options and paintability.
• Polyurethane Low-Expansion Window and Door Foam: A low-
expansion, polyurethane window and door foam is recommended for
installation practices. Avoid using moderate to high-expansion foam
products as operational issues or damage may occur.
• Backer Rod: 1/8" larger than the widest portion of the gap (used in
conjunction with sealant bead for interior air seal).
• Non-compressible or non-water degradable shims.
• Drip cap (if not supplied).
Potential Needed Tools
• Utility knife/shears
• J-roller
• Hammer
• Tape measure
• Caulking gun
• Level (4' minimum recommended)
• Drill with tapered bit and 3/8"
countersink
• Pry bar
Remove Packaging
• Remove shipping materials such as corner covers, shipping blocks,
shrink wrap or pads. If there is a protective lm on the glass, DO NOT
remove it until installation and construction are complete.
• DO NOT remove the installation label until after the inspection of the
job iscomplete.
Inspect Window
• Cosmetic and/or shipping damage.
• Product squareness (diagonal measurements not more than
1/4"different).
• Correct product (size, color, grid pattern, handing, glazing, energy-
efciency requirements, etc.).
• Cracked frame welds or other frame damage.
• Splits, cracks, holes, missing sections or other damage to the nailing n
longer than 6" and/or within 1/2" of the window frame.
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.
Needed Materials
• #10 pan-head or washer-head, corrosion-resistant fastener OR 1 3/4"
galvanized roong nails. Minimum embedment of 1 1/4" into the
structural framing (or as required by local code). Minimum embedment
of 1 1/4" into the structural framing (or as required by local code).
• 4", 6" or 9" wide self-adhered ashing.
• Sill Pan: A pan ashing system (as dened in ASTM E2112) is required
at the sill prior to window/door product installation. A sill pan should
have a positive slope, must be installed onto the sill of the R.O. in a
weather-tight manner and tied into the drainage plane of the building
envelope. For sill pans without a positive slope, place a 3/16"-1/4" tall
plastic shim 2" from each corner and no more than 8" on-center in
between (excludes Canada and potentially large door systems). If an
aftermarket sill pan is preferred, then we suggest the Manufacturer’s
instructions be followed.
