MM Systems Pyro-Flex® BPF-2048F-SC Series
These asymmetrical expansion joint assemblies consist of various designs made up of two parts. The fire-resistive Pyro-Flex® portion consists of flexible, “U”-shaped, ceramic fiber blanket of varying sizes and thicknesses; and the architectural joint system portion, also called an architectural cover plate, which is elastomeric or metallic, able to slide open and close. These fire-resistive joint systems are recognized for use in horizontal assemblies, as well as at the junction or connection point. The horizontal Pyro-Flex® consists of a fire blanket system, which spans to each face of the underside of a floor assembly, forming a protection from the underside of the floor assembly.
