5A. Installation (Windows with Mounting
Flanges – Wrap Pulled Into Opening)
Note: The following installation information is intended to represent a “best
practices” approach and is not intended to address all possible construction
scenarios. Some of the information described below for installation of building
wrap and flashing materials is similar to that described in ASTM E 2112, Method
A1.
1. Install GreenGuard® Building Wrap over the entire exterior wall and
make a modified “I” cut through the building wrap at the window
opening (see Figure 1A). Cut a header flap in the building wrap and
fold material above top of window and tape. Cut building wrap on
sill to promote flashing to wood adhesion (see Figure 1B).
2. Optional Sill Flashing Method No. 1 : Cut a piece of GreenGuard®
SuperStretch ™ Flashing that is at least 12 inches (304 mm) longer
than the width of the rough opening. Remove the release paper
and align the flashing so that it extends 2 inches (50 mm) onto
the sill and up the inside jamb (see Figures 1C and 1D).
