Zip R Sheathing panels make continuous insulation about as foolproof as it gets. As part of the Zip System Sheathing family, these panels are designed to combine multiple layers of building science into a single, easy-to-install product. Each panel integrates structural sheathing with a built-in water-resistive barrier and air control layer, then adds continuous polyisocyanurate foam insulation on the exterior. In just one step, you’re strengthening the wall assembly, improving thermal performance, reducing air leakage, and protecting against bulk water intrusion. It’s a streamlined approach that saves time on the job while meeting today’s stricter energy codes. Zip R Sheathing essentially takes the complexity out of multi-layer wall systems and turns it into a simple, efficient, and highly effective solution for durable, energy-efficient construction.
