CS fire and vapor barrier systems are designed to be used with most of our expansion joint cover assemblies. All fire barrier systems have been tested at Underwriters Laboratories and are UL Classified and Labeled. Multiflex® is a patented system of insulation layers encapsulated in stainless steel mesh. The mesh keeps the insulation in place and allows up to 50% lateral shear, a unique feature in the industry. Multiflex® is supplied in standard 10’ lengths.
