Once the WRB has been installed in accordance with Section 6.0,
proceed with the installation of the GreenGuard ® DC14 as follows:
7.1 Starting at a corner of the building, begin by installing the first
(lower) course of GreenGuard ® DC14 Drainage Mat so that the bottom
of the sheet is aligned with the bottom of the sill plate.
7.2 Continue unfolding the GreenGuard ® DC14 bundle and attach
the sheet to the wall using one of the fastener types described in
Section 4.0. Fasteners should penetrate the stud a minimum of
¾ inch and should be spaced approximately 2 feet apart along
vertical stud locations. The fasteners should be installed so that the
nail head or washer is flush with the surface of the GreenGuard ® DC14
(do not overdrive). The fasteners should be installed on raised areas
only (see Figure 7a).
7.3 Trim the GreenGuard ® DC14 to fit close around all window and
door frames. Installation of a drip cap is recommended at the top of
all window and door heads (see Figure 7b). The drip cap should be
installed prior to installation of the GreenGuard ® DC14. Trim closely
around all wall penetrations, such as electrical boxes, mounting boxes,
pipes, etc.
7.4 Install upper courses of GreenGuard ® DC14 so that the flat edge
overlaps the flat edge on the lower course of GreenGuard ® DC14 by
approximately 2 inches (see Figure 7c).
7.5 As an added level of protection, tape the seams of DC14 using the
GreenGuard ® Contractor Tape described in Section 5.2 (see Figure 7d).
7.6 In areas where the GreenGuard ® DC14 has been cut so that
there is no flat edge to overlap, it will be necessary to use a piece of
GreenGuard ® Flashing to effectively seal the seam by first installing
a piece of self-adhering flashing on the top edge of the lower course
of DC14 as shown in Figures 7e and 7f. Once the upper course
of GreenGuard ® DC14 has been installed, tape the seam using
GreenGuard ® Contractor Tape.
