6.0 GENERAL INSTALLATION OF GREENGUARD® BUILDING WRAPS
The following guidelines should be used when installing GreenGuard® Building Wraps
on exterior walls (see Figure 6.1):
Note: Alternative installation details may be used if approved in writing
by Pactiv Building Products prior to installation.
A. Install building wrap over structural sheathing board, over
foam plastic insulation board with fasteners extending through
insulation into framing members, over exterior gypsum board or
directly to framing members.
B. Begin by aligning the bottom edge of the roll with the base of the
wall, approximately 12 inches around the inside or outside corner
of the wall. The building wrap should overlap through-wall
flashing by a minimum of 6 inches. If no through-wall flashing is
being used, then the bottom edge of the building wrap should
overlap the sill plate at least 2 inches and should be sealed
using seam tape or an adhesive.
C. Unroll the building wrap with the printed side out, wrapping the
entire building, including window and door rough openings. Make
sure that upper courses of building wrap overlap lower courses
in water-shedding fashion. Vertical and horizontal seams must be
overlapped a minimum of 6 inches (vertical) and 2 inches
(horizontal), unless otherwise specified for a particular
application.
All building wrap seams must be taped using 3-inch wide
GreenGuard® Custom Seam Tape or an equivalent tape
approved by Pactiv. See Section 14.5 for an alternative method
of sealing building wrap seams. Ensure that building wrap
surfaces are clean and dry before taping seams. Press tape firmly
as it is applied to the building wrap.
D. Install fasteners based on the required minimum spacing
described in Section 4.0 of this Guide.
E. Fasteners must penetrate the nail base or stud a minimum
of ¾ inch.
F. Do not install fasteners within 6 inches of the sill at window
openings and around door openings. In addition, do not install
fasteners within 9 inches of a window or door head.
G. Make a modified “I” cut through the building wrap at window
openings. Fold excess material to the inside of the rough opening,
trim, and secure to a framing member. Make diagonal cuts at the
corners of the window head, fold the building wrap up, and
temporarily secure it to the wall with a small piece of tape. This
piece will be folded down over the head flashing during the window
installation (see Section 7.0 of this Guide). Note: The final
fenestration and flashing details are the sole responsibility of the
design authority on record for the project. Follow the window
manufacturer’s installation instructions to avoid potential issues
relating to the window warranty. (see Section 7.0 of the Guide.)
H. Seal around all wall penetrations using GreenGuard® Butyl
Flashings or other self-adhering flashings approved by Pactiv (see
Section 7.0 for Flashing Installation Details and Sections 9.0 -
14.0 for Sealing at Terminations and Penetrations).
