Note: The flashing tape must be applied approximately 1/2" onto the frame cladding at the jambs and head. Pre-folding the tape at 1/2" before removing the paper backing will make it easier to apply the tape correctly. If the siding is less than 1/2" thick, adjust the dimension of the fold so the exterior sealant line will cover the exterior edge of the tape.

C.Circle top window:

Apply top flashing tape. First layer: 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

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	'JSTU -BZFS
