INSTALLATION INSTRUCTIONS

for Wood Bay & Bow Windows with Nailing Fin or Exterior Trim (JII032)

1. Fold the head board piece

lengthwise into “L” shape.

Center and apply one leg

to head board and the

other to the wall above the

rough opening header. Cut

the corners to allow the

flashing to lay flat against

the wall.

2. Starting 2" above the

header, apply the side

pieces and overlap the

drain mat on the sill as

shown.

3. Center and apply the

header piece above the

header, overlapping the

side pieces as shown.

4. Press the flashing down

with a J-roller, being

careful to remove any gaps

or bubbles beneath self-

adhesive flashing (remove

and replace if necessary).

Cut four pieces of self-adhesive flashing as follows:

• One head board piece 6" longer than the head board
• One header piece 12" longer than the header
• Two side pieces 7" longer than each side

SPRAY ADHESIVE/PRIMER

Apply spray adhesive/primer
as instructed to nailing fin,
sheathing and building wrap
at the sides and head as
shown.

APPLY THE SELF-ADHESIVE FLASHING

Note!

Keep the edge of the self-adhesive flashing as close to the

window frame as possible and apply over the nail fin.

1. If the window has a pre-

installed cable support

system, follow the

instructions provided by

the manufacturer.

window contents). Primary

support should be provided

under the mull joints of the

unit.

3. Remove temporary support

after full support is

installed.

from above the header

(previously taped up)

and overlap the header

flashing. Seal the ends with

self-adhesive flashing or building wrap tape.

5. Seal all four corners of the window with a 1/4" bead of sealant. Tool

into a fillet shape.

6. The head and seat boards should be protected and insulated with a

structure designed and built as required by local code.

7. Create a continuous air seal

on the interior between

the rough opening and the

drain mat with the window

frame and the rough

opening.
