02 Why It Works
The front fights air and moisture. The back fights heat and cold. Together, they knock out the elements.
-
Built-In Exterior Insulation
Polyisocyanurate rigid exterior insulation on the back of the structural panel reduces heat transfer to help keep homes consistently comfortable year-round.
-
Integrated Water-Resistive Barrier
A resin-impregnated, water-resistive barrier manufactured onto the structural panel eliminates the need for housewrap, sheds water to the exterior and is backed by a 180-day Exposure Guarantee[2].
-
Continuous Air Barrier
Sealed seams with advanced acrylic ZIP System tape and ZIP System liquid flash form a continuous air and water barrier that manages water and reduces air leaks for an energy-efficient exterior.
-
Structural Durability
The integrated structural sheathing system meets wall bracing requirements and contributes to shear wall assemblies. Plus, the engineered wood panel provides a nailable, easy-to-flash base.
03 Code Requirements

With ZIP System R-Sheathing, we are able to essentially terminate ‘thermal bridging’ which is the transfer of heat/cold thru areas of least resistance like common wood on wood framing connections. Hummingbirdhill Homes@hummingbirdhillhomes
