(continued)

B. Cut another piece of 3M™ All Weather Flashing Tape 8067 12" longer than the

opening width. This is in order for the tape to extend 6" up each side of the

opening. Apply the flashing tape to the inside of the sill as shown in Fig. 3B, so it

overhangs 1" into the exterior wall and over the WRB and tape applied in step 1.

Cut the 1" overhang at each corner, as shown in Fig 3B. Fold tape to the exterior

over the WRB or tape and press firmly to obtain good contact and adhesion. This

is the 2

sill flashing tape.

C. Cut another piece of 3M™ All Weather Flashing Tape 8067 12" longer than the

opening width. Apply the tape to the inside of the sill overlapping the 2

sill tape

by at least 1" as shown in Fig. 3C. The tape should NOT extend beyond the

interior face of the framing, and does not need to extend all the way to the interior

of the window opening. This is the 3

sill flashing tape.
