ZIP002SH-R66

ZIP System™ R-Sheathing R-6.6 combines structural wall sheathing, continuous exterior insulation, and an integrated air and water-resistive barrier into one high-performance building envelope solution.

R-6.6 features 1" of rigid polyisocyanurate insulation, providing R-6.6 continuous insulation outside the wall framing. The continuous exterior insulation helps reduce thermal bridging through studs and improves the effective thermal performance of the complete wall assembly.

The exterior face incorporates ZIP System's integrated water-resistive barrier, eliminating the need for a separate layer of traditional housewrap. When seams, openings and penetrations are properly sealed using compatible ZIP System flashing tape or liquid flashing, the system provides continuous air and water protection for the exterior wall assembly.

By combining structural sheathing, continuous insulation and weather protection into one product, ZIP System R-Sheathing can reduce installation steps and simplify construction of energy-efficient exterior walls.

The R-6.6 configuration with 1" insulation provides a strong balance between exterior insulation thickness and thermal performance, making it suitable for high-performance residential and light commercial construction.
