INTEGRATING THE WINDOW TO THE
WATER RESISTIVE BARRIER (continued)
Curve Top and Angle Top Units Only:
A. Units that do not have pre-applied n corners:
Cut four pieces of ashing tape 1-1/2" long. Apply
one piece of ashing tape to each end of the sill n
so that it extends 1-1/2" past the end of the sill n.
Apply one piece of ashing tape to the bottom end
of each exible n, beginning 1-1/2" from the end
of the n and lapping over the ashing tape that
extends from the end of the sill n.

B. For Curve Top Windows: Several
pieces of ashing tape will be
needed to cover the top n.
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 xed extruded n
or for the exible n, just past the
exible weather strip. e top tape
must overlap the one beneath it in
order to divert water properly. e
sharper the arc of the window, the
shorter the pieces of tape will be.
C. Apply top ashing tape to an angle
top window 1/2" up onto the frame
cladding, over the top n onto the
sheathing. On the short side of a
trapezoid window, do not allow the
side ashing tape to extend higher than
what the top tape will cover. Fold the
overlapping tape down, and press all
tape down rmly.
