Fire-rated sealants for floor and wall through-penetrationsFire StopSystemsWhile electrical, plumbing and mechanical Systems are a necessity inbuilding construction, it is often necessary to pass these Systems throughhourly fire-resistive floor or wall assemblies. Typically, openings are cut or drilled through the floor or wall, and then the penetrating items are installed. However, this leaves an opening, or annular space, through which fire can spread. Firestop materials are installed within the openings andaround the penetrants to prevent the passage of flames and hot gasesthrough an otherwise fire-resistive assembly.
5 USG Fire Stop Systems Applications USG Fire Stop Systems consist of special sealants that are trowelled, poured, sprayed, wrapped or caulked around a penetrant (for example, pipe, conduit, duct or cable bundles) through a wall. The sealant prevents the passage of fire through a fire-resistive partition or floor-ceiling assembly.
