3 INTEGRATING THE WINDOW TO THE WATER RESISTIVE BARRIER (continued)

Curve Top and Angle Top Units Only:

A.Units that do not have pre-applied fin corners:

Cut four pieces of flashing tape 1-1/2" long. Apply one piece of flashing tape to each end of the sill fin so that it extends 1-1/2" past the end of the sill fin.

Apply one piece of flashing tape to the bottom end of each flexible fin, beginning 1-1/2" from the end of the fin and lapping over the flashing tape that extends from the end of the sill fin.

B.For Curve Top Windows: Several pieces of flashing tape will be needed to cover the top fin.

Start taping from the sides of the window working toward the peak. To determine the length of cuts, hold the tape along the radius, and cut the tape just past where it leaves the top fixed extruded fin or for the flexible fin, just past the flexible weather strip. The top tape must overlap the one beneath it in order to divert water properly. The sharper the arc of the window, the shorter the pieces of tape will be.

C. Apply top flashing tape to an angle	3C
top window 1/2" up onto the frame
cladding, over the top fin onto the	3C
sheathing. On the short side of a
trapezoid window, do not allow the
side flashing tape to extend higher than
what the top tape will cover. Fold the
overlapping tape down, and press all
tape down firmly.
