2. Cut the building wrap along the marked vertical lines on the sides of the
opening. The cut will end at the parallel point along the bottom of the rough
opening. Remove wrap from the inside of the rough opening and install sill
flashing (see Figure 4B). Follow sill flashing recommendations in Section 5A.
3. Install the window in accordance with the window manufacturer’s installation
instructions. (see Figure 4C). Typically, this requires that a bead of sealant be
applied to the back side of the window flange prior to installing the window.
IMPORTANT: DO NOT SEAL THE BOTTOM FLANGE OF THE WINDOW. Attach the
window using fasteners specified by the window manufacturer.
4. Install the jamb flashing so that it overlaps the sill flashing (see Figure 4D).
Notice that the flashing will now seal directly to the window flange and the
sheathing, while still integrating the edge of the building wrap.
5. Install the head flashing so that it overlaps and extends beyond
the jamb flashing. Fold the building wrap down at the header so that
it overlaps the head flashing (see Figure 4E). As part of the enhanced
installation, seal the diagonal cuts with a section of GreenGuard® Flashing.
Also install a 3-inch section of flashing at the center of the header flap to hold
the wrap in place (see Figure 4F). If the building wrap is the primary air barrier,
then tape across the entire header.
