ABSTRACT:
Flexible composite materials which are suitable for use as fire barriers for either static or dynamic joints are cost effective and easy to install. In one preferred embodiment the flexible composite includes (a) a first layer material having first and second major surfaces, the first layer material including inorganic fibers and a binder in the form of a flexible mat; (b) a second layer material adhered to the first major surface of the first layer material, the second layer material consisting essentially of metal foil, the second layer material having a melting temperature of at least about 350.degree. C.; and (c) a third layer adhered to the second major surface of the first layer material, the third layer material including an intumescent fire retardant composite material.
