02 Why It Works

We introduced the integrated sheathing category. Here’s how building enclosures have evolved.

  • Structural Durability

    ZIP System® panels are available with a Structural 1 rating[1], so you can get shear strength to meet seismic and high-wind-zone requirements.

  • Integrated Water-Resistive Barrier

    By keeping bulk water out but allowing water vapor to pass through, ZIP System® sheathing achieves a delicate balance of water protection and drying potential.

  • Continuous Air Barrier

    ZIP System sheathing and tape forms a tight barrier against unwanted air leakage, for a durable building envelope that helps promote energy efficiency and increase interior comfort.

  • Speed & Ease of Installation

    Quick and simple two-step installation eliminates the need for housewrap, helping to save money on labor costs and improve project cycle times.

  • Quicker Rough Dry-In

    Simply install the panels and tape the seams to achieve a quicker rough dry-in, allowing mechanicals and other trades to start sooner.

  • 30-Year Limited Warranty

    The ZIP System product line is backed by a 30-year limited warranty and 180-day Exposure Guarantee[1].

  • Award-Winning Quality

    ZIP System wall sheathing and tape has been rated #1 in quality every year since 2015 in BUILDER magazine's Annual Brand Use Studies[2].

ZIP System® building enclosures are designed to streamline design and construction.

With integrated structural, water and air management layers, ZIP System® products offer interchangeable options for optimal roof and wall performance. Three panel thicknesses with various dimensional options let you choose the right panel for each design and application. All sizes are engineered to provide optimal roof and wall performance.
