1.5.zip Info

The 1.5-inch panel is a composite material consisting of three primary layers:

: It combines multiple steps (sheathing, WRB, and exterior insulation) into a single installation, which can be faster and cheaper than applying separate layers. 1.5.zip

: In Climate Zone 5, the R-6.6 provided by the 1.5-inch panel is sufficient to keep the sheathing boundary above the dew point, preventing internal condensation when using fiber insulation in the stud cavity. 4. Application and Code Compliance Application and Code Compliance The primary benefit of

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: Other advantages include: Technical Analysis of 1
