This document serves as the installation manual for ZIP System® sheathing and tape, providing detailed guidance on safe, code-compliant installation for both walls and roofs.
It outlines safety protocols, product limitations, handling and storage, panel and tape specifications, recommended fasteners, compatibility guidance, and step-by-step installation practices.
The manual also covers repair instructions for common field issues, and specific details for integrating ZIP System® products with multiple cladding and roof types.
Emphasis is placed on quality installation for warranty coverage, safety compliance, and coordination with manufacturers’ and local building code requirements.
Action Items
None identified in this document. (This is a static installation manual, not a record of a meeting or collaborative session.)
Safety Guidelines and General Use Instructions
Follow all OSHA regulations and use appropriate fall protection during installation.
Install panels and tape only on clean, dry surfaces; do not work during rain, snow, or frost.
Wear appropriate footwear and keep surfaces free from hazards.
Install toe boards temporarily on roofs and tape any holes created by their removal.
You are responsible for meeting all safety and code requirements; consult with Huber Engineered Woods LLC or relevant authorities as needed.
Product Overview, Notes & Limitations
ZIP System® panels are OSB with a built-in barrier, eliminating building wrap or felt underlayment.
Panels must be covered with cladding or roofing within 180 days or additional WRB/underlayment is required.
Not suitable for manufactured housing under HUD code; warranty applies under IRC and IBC.
Do not use ZIP System® tape/sealants below specified temperatures (0°F) or for permanent sealing around round roof penetrations.
Additional WRB layers are required for stucco and adhered stone applications.
Do not apply fluid-applied WRB or coatings over panels except as specified.
Storage, Handling, and Product Specifications
Store panels off the ground, covered but ventilated; release banding in high moisture environments to prevent edge damage.
Use only mechanically attached exterior foam insulation; adhesives are not permitted.
Panels available in multiple thicknesses and lengths; check supply chain for non-standard sizes.
Tape comes in various sizes; follow manufacturing guidance for selection.
Installation – Wall Sheathing
Panels can be oriented vertically or horizontally; maintain 1/8" spacing at all edges.
Fasten with code-approved fasteners, 6" o.c. on edges, 12" o.c. on intermediates.
Overdriven or missed fasteners must be sealed with ZIP System™ tape or liquid flash.
Tape all seams with minimum 3-3/4" wide tape; roll thoroughly for adhesion.
Use ZIP System® liquid flash for additional protection, especially around fasteners.
Follow specific recommendations for flashing and integrating with cladding (brick, siding, stucco, EIFS, stone).
Installation – Roof Sheathing
Panels face overlay side out and should span at least three framing members.
Maintain panel spacing (1/8"); fasten per code and stagger seams appropriately.
For roof pitches ≥4:12, ZIP System® replaces underlayment; 2:12–4:12 requires additional underlayment.
Tape all seams after fastening; roll tape for best air and water seal.
Ice barriers must be installed as required by code—ZIP System® tape does not replace self-adhered ice barriers.
Flashing and Cladding Integration
Use ZIP System™ flashing tape or liquid flash for all seams and transitions.
Specific details are provided for flashing around foundations, pipes, windows, doors, and cladding transitions.
Always follow cladding and roofing manufacturer instructions for integration and fastener requirements.
Common Field Repairs and Fixes
Small holes: Cover with 1–2 layers of flashing tape, overlapping 1" beyond all sides.
Large holes: Remove panel from stud to stud, install new panel and tape seams.
Saw kerfs, chips, underdriven/overdriven fasteners: Cover with tape; roll for adhesion.
Siding removal: Replace WRB, tape edges.
Crane holes: Add blocking, patch sheathing, tape all seams.
Dirty panels: Clean with water and towel, ensure dry before applying tape.
Decisions
Panels and tape must be installed only in dry, clean conditions — Ensures adhesion and maintains warranty.
Additional WRB/underlayment required if panels are exposed for more than 180 days — Preserves product performance and warranty.
Fastener and tape treatments required for overdriven/missed fasteners — Prevents moisture intrusion and upholds warranty.
