Our firestop products for joint systems between walls or between walls and ceilings are listed and tested under the UL 2079 or ASTM E1966 Test Standard Method for Fire-Resistive Joint Systems. For wall or ceiling penetrations, they are tested under the UL 1479 or ASTM E814–Fire Tests of Penetration Firestop Systems listing.

Buildings must ensure that any openings and gaps are fire stopped to restrict both lateral and vertical fire & smoke spread.
