MM Systems Pyro-Flex® PF-2012CF Series (formerly Pyro-Flex® PF-2000CF Series)
These asymmetrical expansion joint assemblies consist of various designs made up of one or two parts. The fire resistive Pyro-Flex® portion consists of flexible ceramic fiber blanket of varying sizes and thicknesses; and, when required, the architectural joint system portion, also called an architectural cover plate, which is elastomeric or metallic, and is able to be compressed and expanded or slide open and close. These fire resistive joint systems are recognized for use in horizontal assemblies that pass through chase wall construction, 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 floor assembly, forming protection from the underside of the floor assembly.
