Flashing Application Instructions for Windows

Based on the climatic conditions and the exposure of the window, there are a

number of different flashing options. The method below is only one

of the recommended options (see Detail VCRDET-102) which meets AAMA

criteria. Refer to the subsequent details (VCRDET-100 to 106) for additional

flashing options located on pages 27-33.

Step One:

Pre-cut the Grace Vycor

Plus flashing using the

measurement markings.

The length of the flashing

should extend beyond the

sill equal to the width of the

jamb flashing (see Table I,

page 8).

Step Two:

Before installing flashing

on sill and jambs, locate

the RIPCORD.

Split the release paper

in half allowing for easy

installation.

Step Three:

Rewind the pre-cut flashing.

Position inside rough opening

on the vertical jamb 9 inches

up on each side. Apply to win-

dow sill, removing half the

release paper and exposing

the adhesive.

Roll firmly into position.

Make vertical relief cuts

starting from corner of win-

dow sill upward. Roll firmly

into place as necessary.

Note: Do not remove the

release paper on the bottom

half of the flashing until

future tie-in with the

weather-resistive barrier.

WINDOW INSTALLATION

METHOD A: BEFORE WEATHER-RESISTIVE BARRIER

Install window as per manufacturer’s recommendation.

If sealant is used, ensure all excess sealant is removed from

nailing flange and surrounding area to provide a smooth con-

tinuous substrate. (ASTM does not require a sealant on top

of window flange when using self-adhered flashing.)
