Fire barrier component

Abstract

A fire barrier component has an outer sleeve retaining and protecting a fire stop material therein which is preferably compressed. The outer sleeve when exposed to a fire condition partially fails and the fire stop material forms the fire stop barrier. The fire stop material if compressed expands and can cooperate with adjacent components to form an effective fire stop barrier. The firestop barrier component can be factory made and used in complete fire barrier systems, or the component can be used as part of a specific field application. The component may be sold in longer lengths and cut as required to meet a particular application. Conventional saws work satisfactorily in cutting of the component while maintaining the performance of the component when exposed to a fire condition.
