PREPARE MASONRY OPENING WITH BUCK
1. Seal any joint larger
than 1/16" in the buck
and between the buck
and the concrete/
masonry with sealant.
2. Cover the buck and
the surrounding
concrete/masonry at
the head and jambs
with liquid applied
ashing as shown.
3. If installing into a
four-sided buck,
seal the sill in a
similarmanner.
Note! Where the
window will sit on the
sill, shim to provide
continuous support to
the sill. This shimming
must be 1/2" shorter
than the width of the
window frame, 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.
4. Center the continuous support on the sill of the opening, ush to the
exterior edge and leaving a 1/2" gap at the ends. Secure in place.
END of Buck Instructions, SKIP to section 4, “INSTALL WINDOW.”
PREPARE STUD-FRAMED WALL
PREPARE BUILDING WRAP
Trim building wrap
ush with the edges of
the rough opening (or
follow manufacturers’
instructions for
trimming).
PREPARE/SHIM THE SILL
1. Use self adhesive ashing to waterproof the sill.
2. Flashing must have at least 1"
of material wrapped below
the sill onto the vertical wall.
Flashing width must be at
least frame width + 1".
3. Measure the width of the
frame 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".
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. Staple ashing
to the wall, if needed, and seal
the corner edges as shown.
8. Smooth out any bubbles or
creases with a J-roller.
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
1/2" shorter than the width
of the window frame, 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.
