5. Place ashing on rough
opening sill, wrapping the
ashing up 6" on each jamb
as shown.
6. Pull release tape and set
ashing into place.
7. Fold the ashing down onto
the sheathing. Mechanically
fasten if necessary.
8. Smooth out any bubbles
or creases with a J-roller.
Remove and replace
ifnecessary.
9. Install the shimming support
as follows:
Note! Where the window will
sit on the sill, shim to provide
continuous support to the sill.
This shimming must be 1/4"
narrower than the depth of
the window frame sill, should
level the rough opening
sill and be no more than
1/4"thick.
10. Align the shimming on the sill ush with the exterior and centered
between the side jambs. If installing a mulled unit, leave gaps at the
mull joint(s) so they don't sit on the shimming and tack into place or
secure 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 adhesive 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 + B + 1 3/4".
3. Measure the width of the
frame from the interior to
the nail n (measurement A)
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 fin
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
shimming and tilt into
the rough opening. The
window sill must rest on and
be fully supported by the
shimmingsupport.
3. Fasten window with a
galvanized roong nail
through the nail n
between 3"- 7" from one
upper corner.
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).
