Field applied water-soluble borate insecticide or fungicide treatments
applied to the non overlay side of the panel. See technical tip, "Termite
Treatments on ZIP System Roof & Wall Sheathing," on zipsystem.com for
more information.
Permeable laminated radiant barrier foil or paint. For a radiant barrier foil or
coating to be considered permeable, it must have an applied permeance of
five perms or greater as tested by the ASTM E 96 wet cup standard. For a
radiant foil, the permeance evaluation would include any adhesive and/or
backer used to laminate a foil. For a radiant paint/coating, the permeance
evaluation should be conducted at the applied thickness of the paint/coating.

Step 1. �^
Apply Z P System tape to every vertical and horizontal panel seam. It is
at the discretion of the installer whether to apply tape from the top down
or from the bottom up. However, working from the highest sections of
the roof�,and working down will minimize foot traffic on the tape.
Ensure hat the tape is centered over the seam within +/- 1/2" to provide
adequa ie coverage and to ensure that wrinkles in the tape are minimized.
Ensure that tape lengths are continuous across the 8' horizontal edge
of the panels. If splices are unavoidable, create an overlapping splice
of at le Est 3". Apply moderate pressure onto the surface of the tape to
ensure la secure bond between the panel and the tape.
Use ZIP System tape gun or tape roller to apply pressure to the tape
and smlooth out any wrinkles.
Take s El ecial care to remove any voids and/or trapped air at splice
areas 49d T-joints.
Step 2.
- For valley areas of framing, we recommend you use 6" wide ZIP System
tape. T �lis tape is wider than panel seam tape and is designed to give you
optima l protection in valley areas.
- Starting) from the bottom and working your way up, apply one continuous
piece of 6" tape so that the center of the tape is over the valley seam.
- Use th' f tape gun or tape roller to apply pressure to the tape to ensure
proper contact with the panel and to eliminate any wrinkles that might
have occurred in the tape. Take special care to seat tape completely
into th valley.
Note:
It is important to pay extra attention to valley taping as water is
directid toward the valleys during rain events.
Self -a hering ice and water barriers may be required by code. ZIP
SysterM tape is not considered a replacement for self -adhering ice

adhesive -backed flashing tape (must meet [CC -ES
Acceptance Criteria for Flashing Materials (AC148))
and apply to the rigid head flashing, ensuring
that the adhesive -backed flashing overlaps the
jamb flashings.
Once the tape is in place, use the tape gun or rollert
to seal the flashing to the sheathing.
10. From the interior, apply low-pressure polyurethane
foam (for windows) between the rough opening and
the window frame. (Caulk sealant compatible with
the sill flashing may be used at the sill if the opening
between the sill flashing and window is too narrow
to allow the use of low-pressure polyurethane foam.)
When using ZIP System tape, butyl, 100`/o silicone
or polyurethane sealants are acceptable. Do not
use latex or other water -based sealants with ZIP
System tape. If using another flashing tape, follow
the flashing manufacturer's recommendation in
selecting a sealant compatible with that flashing.
