: It combines multiple steps (sheathing, WRB, and exterior insulation) into a single installation, which can be faster and cheaper than applying separate layers.
The primary benefit of the 1.5-inch ZIP-R system is the elimination of . In traditional framing, wood studs act as thermal bridges, conducting heat out of the building. The 1.5-inch ZIP-R provides continuous insulation that can cut wall heat loss by 20–30% compared to cavity-only insulation. Other advantages include:
: A factory-applied water-resistive and air barrier on the exterior face. Key Performance Metrics: R-Value : Provides a thermal resistance of R-6.6 .
: A layer of high-quality OSB that provides shear strength.
