155 - ZIP-R on the Roof? Structural, Hygrothermal & Durability Tradeoffs
Can ZIP-R panels work on a roof—and should they? Steve, Jake, and Nick Sabol from Huber’s Technical team dig into a topic that’s getting a lot of attention in the field.
This episode breaks down the full set of considerations behind putting insulated sheathing on the roof deck: structural loading, fastening and shear, hygrothermal behavior, condensation risk, and long-term durability.
