architect of record or other authority having jurisdiction. Please
acknowledge that it is solely your obligation for all safety
requirements and code compliance. For additional information,
contact Huber Engineered Woods LLC.
ZIP System® R-Sheathing Safety Guidelines
- Follow all OSHA regulations and any other safety guidelines and safety
practices.
- Use approved safety belts and/or harnesses or other fall protection
equipment.
- Install ZIP System® R-Sheathing and ZIP System™ tape only in dry
conditions and on dry surfaces. Do not install in rain, snow, frost or other
slippery conditions.
- Do not apply flame directly to foam layer. Foam will burn and smoke if
exposed to an ignition source of sufficient heat and intensity or open
flame, such as a welder's torch.
What is ZIP System® R-Sheathing?
ZIP System® R-Sheathing panels consist of an oriented strand board panel
laminated with a water-resistive facer on the exterior and a rigid foam
insulation panel bonded on the opposite (interior) face. When properly
installed and taped, ZIP System R-Sheathing provides a water-resistive
barrier, air barrier and exterior insulation in one product. It may also be
used in the construction of braced wall panels or shear walls in certain
conditions. See the Structural Bracing to Resist Lateral Forces section of
this installation manual for more information.
The OSB substrate complies with Voluntary Product Standard PS2 for wood
structural panels and the water-resistive barrier complies as an alternate to
the water-resistive barrier prescribed in the code. ZIP System® R-Sheathing
is available with a 1/2-inch, 1-inch, 1-1/2-inch and 2-inch foam insulation
panel.
ZIP System® R-Sheathing Includes:
- ZIP System® wall sheathing panels with built-in water-resistive barrier
and preprinted fastening and tape guides.
- Foam insulation panel.
- ZIP System™ tape.

- Outdoors, cover panels loosely with a waterproof protective material such
as a tarpaulin.
- Anchor covers on top of the stack, but keep away from sides and bottom
to assure good air circulation.
- In high moisture environments, cut banding on the panel stack to prevent
edge damage.
- Factory applied packaging is intended only for protection during transit.
- Packaged units must be stored indoors or within a covered structure.
- For temporary job-site storage, units should be stacked on pallets at least
three inches above ground level and completely covered with a
weatherproof covering such as a tarpaulin.
- The temporary factory-applied packaging should be slit or removed to
prevent accumulation of condensation.
- Do not stack more than three units high.
ZIP System® R-Sheathing Notes and Limitations
- ZIP System® R-Sheathing is approved for wall use only. Do not use on
roofs.
- Do not use abutted against stone or masonry without providing a
minimum of a 1/2-inch gap.
- Do not install ZIP System™ tape in temperatures less than 20° F.
- ZIP System R-Sheathing products are not approved for manufactured
housing applications that are built under a federal building code
administered by the U.S. Department of Housing and Urban Development
(HUD).
- Not intended to replace traditional wood structural panels in applications
where the wall sheathing is designed to resist combined wind uplift and
shear.
- Do not use in fire-rated assemblies in lieu of a required “wood structural
panel.”
- Do not apply secondary coatings to the overlay on ZIP System
R-Sheathing.
- Minimum 1/2-inch gypsum wall board must be installed on the interior
side of the wood wall studs as a thermal barrier using code-recognized
fasteners per IRC or IBC requirements.
- Only use in buildings of Type V construction or construction permitted
under the International Residential Code.
- In areas where the probability of termite infestation is “very heavy” the
clearance between ZIP System R-Sheathing and finished grade shall be no
less than 6-inches.
Note: In cladding systems requiring multiple layers of water-resistive
barriers, like traditional hard-coat stucco and adhered stone veneers,
ZIP System® R-Sheathing is intended only to replace the first layer.

ZIP System® R-Sheathing Installation Manual
ZIP System® R-Sheathing Installation
Overview: ZIP System® R-Sheathing is composed of ZIP System® wall sheathing panels, laminated exterior foam panel insulation and ZIP System™
seam sealing tape. ZIP System R-Sheathing panels should be fully installed before the seam sealing tape is applied. The following manufacturer
installation steps and recommendations are presented as a general outline of the installation process. You are fully and solely responsible for all safety
requirements. Good construction practices should be followed at all times.
Step 1. Install any necessary mechanical strapping directly to
framing. Any metal straps, ties or other connectors designed to
resist uplift, shear or diaphragm loading must be installed prior to
ZIP System® R-Sheathing installation. The requirement for
mechanical uplift connections shall be determined by the designer-
of-record, local building codes or authority having jurisdiction. Detail
A should not be considered typical and only applies when
mechanical uplift connections are specified.
Straps, ties and connectors installed on the exterior face of stud
will not be visible after ZIP System® R-Sheathing panels are
installed. Schedule any necessary anchor or nailing inspections
accordingly.
DETAIL A
Step 2. Install ZIP System® R-Sheathing panels positioned with the
water-resistive barrier facing out. The panels may be installed with
the long side of the panel oriented either horizontally or vertically to
the framing members. Wall panels that are designed to resist lateral
shear forces should have solid framing or blocking behind all panel
edges. Foam insulation is oversized on one 4-ft and one 8-ft. edge
relative to the ZIP System R-Sheathing face to accommodate proper
gapping of panels. Panels should be installed with foam edges
touching. Please coordinate panel field placement and orientation in
order to take advantage of this gapping feature.

Step 3. Fasten the panels to the framing members with code
approved fasteners. When used to resist lateral forces, nail
fastener penetration into the wood wall stud should be a minimum
of 1 1/2-inches. If staples are used (R3 and R6 only), fasteners must
penetrate a minimum 1-inch into the framing. See, Structural
Bracing to Resist Lateral Forces, on page 5, for fastener and
fastener spacing options. It is the responsibility of the general
contractor to ensure correct fastener type and spacing prior to
installation. Apply fasteners 3/8 inch from panel edge.
DETAIL B
ZIP System® R-Sheathing thickness may influence building interior
and exterior dimensions, framing layout or foundation design for
anchored veneers. For example: Foundation brick ledges may
need to be wider when using ZIP System R-Sheathing (See DETAIL
G on page 9), or wall stud placement may need to be adjusted
from building corners to allow for sheathing thickness. Designer
and general contractor should make necessary adjustments (if
any) to the design and/or construction methods to accommodate
these changes.
ZIP System® tape must be installed using a roller to apply
pressure to the pressure sensitive adhesive layer of the tape.

ZIP System® R-Sheathing Installation Manual
Structural Bracing to Resist Lateral Forces
ZIP System® R-Sheathing wood-framed walls may be designed to resist lateral shear forces by prescriptive or engineered methods in accordance with the
International Building and Residential Codes (See Table 1 and Table 2 below). All seams between panels used to resist lateral loads must be backed by solid
wood framing. If the panel is not required for structural bracing, the panels should be installed with a minimum 0.131” shank diameter nails (minimum 1-
inch embedment into wood studs) spaced at 6 inches on center on panel edges and 12 inches on center in the field of the panel. Minimum 1/2-inch thick
gypsum wallboard must be installed as a thermal barrier in accordance with Chapter 26 of the IBC or Chapter 3 of the IRC.
Installation When Not Part of Lateral Force Resisting System
ZIP System® R-Sheathing that is not intended to resist wind or seismic
loads may be attached to framing using 0.131” diameter shank nails.
Nails must penetrate the studs at least 1 inch.
Installation When used in Wall Bracing or Shear Walls
ZIP System® R-Sheathing may be used in the construction of braced wall
panels in accordance with WSP bracing method (2009 IRC) as an
equivalent alternative to the prescribed wood structural panels ONLY if
installed per Table 1 below. All requirements, restrictions and limitations
listed in the IRC regarding the applicability and use of prescriptive wall
bracing methods still apply.

ZIP System® R-Sheathing Installation Manual
ZIP System® R-Sheathing – Tape Installation
Apply ZIP System™ tape after ZIP System® R-Sheathing panels are fully fastened to wall framing. Only ZIP System tape should be used to seal the seams of ZIP
System R-Sheathing. Make sure that the panel surface is dry and free of sawdust and dirt prior to taping. ZIP System tape is a contact tape that requires
application pressure for an adequate seal.
Step 1. Tape all seams using ZIP System™ tape. Center the tape over
the seam within +/- 1/2 inch to provide adequate coverage and
reduce wrinkles in tape.
Use the ZIP System™ tape gun or ZIP System® roller to apply pressure
to the tape and smooth out any wrinkles.
Step 2. Wherever tape splices occur at a horizontal or vertical seam,
create an overlapping splice of at least 3 inches.
At T-joints, the tape pieces should overlap by at least 1 inch. Apply
pressure onto the surface of the tape to ensure a secure bond
between the panel and the tape.
Use the ZIP System™ tape gun or ZIP System® roller to apply pressure
to the tape and smooth out any wrinkles.
Take special care to remove any voids and/or trapped air at splice
areas and T-joints.
Step 3. Tape inside and outside corner seams.
Tip: When taping inside corner seams, it is helpful to cut a
manageable length of ZIP System™ tape and hold the ends in the
middle using only your index fingers and thumbs. Slightly pulling
both ends of the tape causes the tape edges to naturally curl inward.
With the tape in tension, place it in the inside corner. Repeat as you
go up the full height of the wall.

the general contractor to coordinate rough opening dimensions with window dimensions and install any necessary extensions or solid blocking as needed.
Step 1. Install sill/pan flashing that satisfies the requirements of
ASTM E 2112 and AAMA 711into the rough opening. ZIP System™
tape or ZIP System™ stretch tape may be used as pan flashing. Other
adhesive-based flashing tapes may be used if they satisfy ICC-ES AC-
148 or AAMA 711.
Step 2. From the interior of the rough opening, apply low-pressure
polyurethane foam (for windows) between the rough opening and
the window frame. (Caulk sealant compatible with the flashing and
backer rod may be used in lieu of polyurethane foam.) When using
ZIP System™ tape, 100% silicone, butyl and polyurethane sealants are
acceptable.
