ZIP SYSTEM® SHEATHING // OVERVIEW

ZIP System® roof and wall sheathing panels are oriented strand
board (OSB), wood structural panels with built-in protective
overlays that eliminate the need for building wrap or roofing
felt. Install the panels, tape the seams with ZIP System
and the building is rough dried-in.

When used on a wall, ZIP System

®

sheathing functions as a
combination wall sheathing and code-recognized water-resistive
and air barrier. The sheathing panel seams are sealed with
ZIP System
When ZIP System

tape, protecting the wall from water intrusion.

®

sheathing is utilized for roof applications,
felt underlayment is not required. In wall and roof coverings
system requiring multiple layers of water-resistive barriers or
underlayment, ZIP System

®

sheathing and tape is intended to

replace only the first layer.

ZIP System

®

sheathing may be used for roofs and walls in
Type V construction, in Type III construction as roof sheathing
only, and other construction permitted under the International
Residential Code.

ZIP System

use a primer such as 3M Hi-Strength 90 or rub the tape with an

ZIP System seam tape is shown.

WRINKLES IN THE TAPE

Rolling the tape during installation will significantly reduce the
chance of tape wrinkling occurring. If wrinkles occur in the ZIP
System™ tape there are two options. First, try to roll the wrinkles
out with the ZIP System™ tape roller. This should help eliminate
any wrinkles or fish mouths (avenues for water to get to the seam).
Secondly, if rolling the tape does not remove the fish mouths that
section of tape can be removed and a new piece of tape must be
applied that overlaps the existing tape by three inches or place
anther piece of tape over the fish mouth and roll the tape.

ZIP SYSTEM® SHEATHING // NOTES & LIMITATIONS

Do not use on roofs with slopes less than 2/12.

Do not use abutted against general stone or masonry

without providing a minimum of a 1/2" gap.

ZIP System products are not recommended for

manufactured housing applications that are built

12

under a federal building code administered by the
U.S. Department of Housing and Urban Development
(HUD).

™

Do not use ZIP System

tape to permanently seal
around circular roof projections (plumbing vents,
pipes, curved walls, etc.)

When original roofing is removed and replaced on

®

existing ZIP System

sheathing, the roof should be
covered with an additional roofing underlayment prior
to installation of the new finished roofing or cladding.

In roofing systems requiring multiple layers of water-

®

resistive barriers, like clay tile, ZIP System

sheathing

is intended to replace only the first layer.

// GENERAL INSTALLATION - ROOF

The following installation steps are presented as a general

installation recommendations – please visit ZIPSystem.com for
a library of flashing and installation details. You are fully and
solely responsible for all safety requirements. Good construction
and safety practices should be followed at all times.

ZIP SYSTEM® ROOF SHEATHING

// PANEL ORIENTATION AND SPACING

Ensure that the panel surface is dry and clean of any nails,
sawdust, or other debris or protrusions prior to installing or
walking on the panels.

After ensuring compliance
with all OSHA and local
code safety guidelines, install

®

ZIP System
with the moisture barrier
surface facing outside. The long
edge (8’) should be oriented

sheathing panels

perpendicular to the framing
members, and panels should be
installed with the 4’ edge seams

INSTALLATION MANUAL - ROOF

ZIP SYSTEM® ROOF SHEATHING // FASTENING

Fasten the panels to the framing members with code approved
fasteners. Space fasteners 6" o.c. along supported edges and 12" o.c.
at intermediate supports, unless otherwise specified by local code or
the designer of record. It’s the responsibility of the general contractor
to verify proper fastener type and spacing prior to installation. Apply
fasteners 3/8" from the ends and corners. ZIP System sheathing does
not have proprietary diaphragm values and have the same diaphragm
values of OSB or plywood of equivalent thickness.

14

HUB 81824 REV 9/18

ZIP SYSTEM® SHEATHING AND TAPE

INSTALLATION MANUAL - ROOF

ZIP SYSTEM® ROOF SHEATHING

// PANEL ORIENTATION AND SPACING

1/8” spacing between square edges of
all adjacent panels is recommended, in
accordance with industry standards for
wood sheathing. The unique edge profile
is designed to accommodate incremental
panel expansion and does not require
manual gapping along the 8’ edges.

15

Maintain 1/8” space wherever the tongue
and tongue profile does not exist. Unique
edge profile is on 8’ edges only. Ensure

®

that ZIP System

panels span at least three
framing members and a framing member
supports the entire 4’ edge of the panels.

We recommend the use of code recognized fasteners with the head

®

of the fastener driven flush to the surface of the ZIP System

panel.
Flush fastener placement is best achieved by properly setting the nail
gun air compressor to the manufacturer’s recommended setting or
using in-line pressure regulators. Many nail guns have depth control
adjustments to ensure fasteners are driven flush. For tools that do
not have a depth control adjustment feature, we recommend fitting
a flush drive attachment collar on the end of the gun to help limit
fastener embedment depth.

Ensure that the tape is centered over the seam within
+/- 1/2" to provide adequate coverage

Wherever tape splices occur at a horizontal or vertical
seam, create an overlapping splice of at least 3".

At T-joints, tape pieces should overlap by at least 1".

Tape over any areas of the panel that are damaged
during construction.

Use the ZIP System

to the tape and smooth out any wrinkles.

Avoid stepping on tape in high temperature

H-CLIPS

Huber Engineered Woods requires panel edge support for
7/16" ZIP System® sheathing installed on roof supports
spaced more than 16" on center. Panel Edge support might
be blocking, tongue-and-groove edges or panel edge clips
(H-clips).

18

When taping over H-clips, it is important to make sure that the
tape is centered and adequate pressure is applied on all sides
of the clip to ensure a proper seal. It should be noted that
the use of edge support (H-clips, blocking, tongue-and-groove
edges, etc.) does not increase the maximum allowable load on a
roof for a given truss or rafter spacing.
