4.B. Installation of Building Wrap at Window Frame Detail
Figure 4 shows an example of a window frame detail where the building wrap
is installed over the sheathing and is wrapped around the window jambs to the
interior of the wall. Windows should be sealed in accordance with the window
manufacturer’s installation instructions.
4.C. Installation of Building Wrap at Exterior Electrical Boxes
All exterior electrical boxes and other penetrations through the building wrap
should be sealed to prevent air and moisture intrusion at the openings. The
building wrap must be taped to the electrical box in order to provide an adequate
seal (see Figure 5).
4.D. Installation of Building Wrap at Wall Penetrations
When penetrations, such as those for pipes and ducts, breach the building wrap,
they must be sealed to the building wrap using a sealant that is compatible with
both the building wrap and the pipe or duct material (see Figure 6).
4.E. Installation of Building Wrap (Roof/Roof and Roof/
Wall Intersections)
GreenGuard® Building Wrap should overlap the step flashing at the
roof to wall intersection (see Figure 7).
