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.
  • Install temporary toe boards on roofs; seal holes after removal.

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.
  • Tape sizes: Flashing tape (3-3/4", 6", 9", 12"); stretch tape (3", 6", 10").
  • 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.

Decisions

  • Product limitations and requirements adopted for compliant installation — Ensures safety, code compliance, and preservation of product warranty.

Open Questions / Follow-Ups

  • For project-specific compliance or unusual conditions, consult the engineer/architect of record or contact Huber Engineered Woods LLC for clarification.
  • Confirm local code requirements and compatibility with third-party products as needed.
