Which code commonly governs firestop requirements in the U.S.?
The International Building Code (IBC) establishes fire-resistance ratings and requires proper firestopping of penetrations and joints.
What does UL 1479 specifically address?
UL 1479 is the standard for fire tests of penetration firestop systems and evaluates their ability to prevent the spread of fire.
Which organization publishes codes that influence firestop system requirements?
The International Code Council (ICC) develops the International Building Code (IBC) and other construction codes used in the U.S.
What is required by IBC when sealing penetrations in fire-resistance-rated assemblies?
Penetrations must be sealed with tested and listed firestop systems that maintain the required fire-resistance rating of the assembly.
Which standard evaluates firestop systems in joint applications?
UL 2079 is the test standard for evaluating the fire resistance of firestop systems used in building joints.
Why is third-party listing important for firestop systems?
Third-party listing ensures that a firestop system has been independently tested and meets specific fire-resistance performance standards.
