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 + B + 1 3/4".
3. Measure the width of the
frame from the interior
to the nail n/trim
(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.
SEPARATELY SUPPLIED DRIP CAP
This step applies to nail fin
units only, windows with
exterior trim will install drip
cap in section 6, “INSTALL
WINDOW.”
Lay a 1/4" bead of sealant
across the header as shown,
and tap the drip cap into the
groove with a wood block.
SEAL WINDOW
• For units with exterior trim: inspect the bead of sealant around the
interior of the window where the trim meets the window frame. Add
more sealant as necessary to ensure a water tight seam.

4. Cut a piece of ashing the
length of the sill plus 12".
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 wall. Mechanically fasten
if necessary.
8. Smooth out any bubbles
or creases with a J-roller.
Remove and replace
ifnecessary.
9. Install the continuous
support as follows:
Note! Where the window will
sit on the sill, shim to provide
continuous support to the
sill. This shimming must be a
minimum of the width of the
window frame and a minimum
of 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, shim under the
mull joint(s) and tack into place or secure with sealant.
INSTALL MASONRY CLIPS ON THE SILL
Note! Install clips on any
windows that DO NOT have
exterior trim or a fin on
thesill.
1. Install masonry clips 4" from
each corner and every 16"
on center under sill with two
#8 x 3/4" screws per clip.
