About Fire-Rated Assemblies
Entries marked Verified reproduce real UL Designs or GA Files and link to the published source they were checked against — always confirm the current listing in UL Product iQ or the GA Fire Resistance Design Manual before specifying, since listings change and include item-level options not shown here. Entries numbered BS-… are generic illustrative examples of typical construction: they are not tested designs and must not be cited on construction documents. Substituting any material in a listed assembly may void its rating.
