The FSC Steel and Wood Wall Calculator tools provide water vapor control guidance to the user. The technical basis for the water vapor control checks has served as the basis for significant updates to the water vapor retarder provisions of the 2021 and 2024 editions of the IBC (Section 1404.3) and IRC (Section R702.7). While the calculator strives for code consistency, it has intentional differences and provides additional features that are omitted from the limited prescriptive scope of the codes.
