6.5 Install self-adhering flashing (see Section 5.1) in shingle
fashion by first installing the sill flashing (see Figure 6c). Then install
the window in accordance with the manufacturer’s installation
instructions. When the window is in place, install the jamb and
head flashings in shingle fashion (see Figures 6d and 6e). Then
cover the head flashing at the top of the window with the building
wrap (see Figure 6f).
6.6 When the end of the roll is reached, fold the edge of the
building wrap under itself and fasten securely.
6.7 Vertical and horizontal seams must be overlapped a
minimum of 6 inches (vertical) and 2 inches (horizontal) unless
otherwise specified for a particular application. Upper courses
of building wrap must overlap lower courses in water-shedding
fashion. Building wrap seams can be taped using GreenGuard ®
Custom Contractor Tape or an equivalent tape approved by Pactiv
(optional, see Section 5.2). If the building wrap is intended to
perform as the primary air barrier in the wall system, then all
seams must be taped and all penetrations must be sealed using
GreenGuard ® Contractor Tape, GreenGuard ® Flashings, sealant, or
spray foam.
