creases with a J-roller. Remove
and replace if necessary.

sagging or bowing. Shims should be aligned in the following fashion:
• Near the exterior edge of
thesill.
• One shim placed 3/4" to
1" in from each side of the
roughopening.
• No more than 24 inches
on center between
additionalshims.
• For mulled units ensure
there is a shim located 1/2"

Shims may be temporarily held in place with sealant.
Prepare Building Wrap
NOTE: Check with the
building wrap manufacturer
to verify the following steps
will not void their product
warranty.
1. Trim building wrap ush with
the rough opening.
2. At the head, cut building wrap
at 45° and tape up as shown.
3. Trim the sides sufciently to
allow the nailing n to be mounted against the sheathing.
Prepare/Shim the Sill
1. Use self-adhered ashing to
waterproof the sill.
2. Flashing must have at least 2"
of visible material below nail
n. Flashing width must be at
least measurement A (Frame
Width) + B (Nail n Width)
+13/4".
3. Measure the width of the frame from the interior to the nail n and
subtract 1/4". Transfer this measurement from the outside edge of the
rough opening sill and draw
a line all along the rough
opening sill. This is where the
back of the ashing will sit.
4. Cut a piece of ashing the
length of the sill plus 12".

WARNING! To avoid injury, use at least two people to install.
Adequately support the window until completely fastened.
1. Run a continuous 3/8" bead
of sealant around the interior
side of the nail n on the side
jambs and head. On the sill,
leave at least a 2" gap every
8" where it will contact the
rough opening.
2. Place window onto the
shims and tilt into the
roughopening.
3. Fasten window through the
nailing n between 3"- 7"
from one upper corner.
NOTE: On some double-hung
operating units only, jamb
adjuster hardware is mounted in
the middle installation holes to
allow for some jamb adjustment.
Install jamb adjuster screws until
captured (rst ‘click’), the screw
may then be screwed in or out to
adjust the jamb as needed.
4. Shim at each interlock, or in
the center, and within 4"- 6"
of each corner on the side and
head jambs. Apply additional
shims to the side and head
jambs as necessary to ensure
window position within the
opening is plumb, level, and
square. Larger windows
usually need additional shims.
Shims can be secured with
sealant or adhesive.
5. Inspect window for square,
level, and plumb. Test for proper
operation (remove and reinstall
ifnecessary).
