Summary
| Description | "HOW" (Head Of Wall) Building Joint: Concrete Masonry Unit Wall stopping short of the underside of a concrete slab above. The joint is penetrated both by electrical conduit (EMT = Electrical Metallic Tubing) and a steel pipe. Building joints are routinely penetrated by mechanical and electrical penetrants. For that reason, joint firestops that are also qualified to be used in mechanical, electrical and structural through-penetration firestop systems provide the best evidence of building code compliance because they have demonstrated the ability to cope with the heat that travels through to the unexposed side during an accidental or test fire exposure - without spontaneous ignition or degradation that would fail the hose-stream test or permit smoke migration. |
