Safety Guidelines
Follow OSHA regulations and local safety codes during installation.
Use appropriate fall protection, ensure dry installation conditions, and wear high-traction footwear.
Remove debris and tripping hazards from panel surfaces before installation.

Product Overview and Limitations
ZIP System® sheathing panels are OSB with a built-in overlay, eliminating the need for separate wraps or underlayments for most wall/roof applications.
Achieves rough dry-in after proper flashing and window/door treatment.
Compatible with a wide range of claddings and roof coverings, but not for HUD code manufactured homes.
Must be covered by finish cladding/roofing within 180 days or an additional WRB/underlayment is required.
Restrictions apply to certain uses, flashings, and cladding transitions; see manufacturer requirements and local codes.
Storage, Handling, and Compatibility
Store panels off the ground with air circulation; cover loosely with waterproof material outdoors.
Tape and stretch tape are pressure-sensitive and must be rolled to achieve a full bond.
Compatible with a variety of substrates; do not apply adhesives for foam insulation.
Consult additional technical tips on fastener and sealant compatibility at the manufacturer’s website.
Panel and Tape Specifications
Panel thicknesses: 7/16", 1/2", 5/8", with various sizes and edge profiles.
Markings on panels assist with framing but do not dictate fastener placement.
Use code-approved fasteners; follow spacing and edge distance recommendations.
Wall Sheathing Installation
Panels may be installed horizontally or vertically, water-resistant side out.
Maintain 1/8" spacing between all square panel edges; manual gapping required for 4' edges.
Fasten with code-approved hardware; use flush fastener placement.
Overdriven or missed fasteners must be sealed or replaced per warranty guidelines.
Taping: Use minimum 3-3/4" ZIP System™ flashing tape or liquid flash, centered and overlapped at seams, corners, and T-joints. Always roll the tape.
Common Wall Details
Foundation transitions: Provide proper alignment and flashing.
Penetrations (pipes/windows/doors): Detailed multi-step taping and flashing requirements; follow sequences for each penetration, using stretch tape and sealants as specified.
Cladding: Follow specific details for lap siding, brick, stucco, adhered stone, EIFS, decks/porches, and transitions to masonry.
Always check and follow additional manufacturer and code requirements for fasteners and water barriers.
Roof Sheathing Installation
Panels installed with overlay facing out; maintain 1/8" spacing at all panel edges.
Orient long (8') edge perpendicular to framing; stagger seams as required.
Use code-approved fasteners, placed flush.
ZIP System® sheathing replaces one layer of underlayment for roof pitches ≥4:12; additional underlayment required for 2:12–4:12 pitches; below 2:12, acts as structural decking only.
Common Roof Details
Taping: All seams taped with 3-3/4" (or wider for valleys) ZIP System™ flashing tape; roll for full adhesion.
Ice barriers may be required per code; install in addition to ZIP System tape.
Flashings (drip edges, valleys, ridges, pipe boots): Use ZIP System flashing tape; special instructions for valleys and ridges.
Repairs for holes, kerfs, chips, and dirty panels provided; follow respective multi-step procedures.
