03 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, 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].
