[ What is claimed is:] [1.] A fire barrier system for a joint formed between a first structural element having a first attachment area and a second structural element having a second attachment area, the first and second structural elements defining a space having a width and a length, the width varying from a minimum width to a maximum width as the first and second structural elements move with respect to one another, the fire barrier system comprising:a flexible sheet of a fire barrier material comprising a first portion attachable to the first attachment area by a first attachment means, a second portion attachable to the second attachment area by a second attachment means, and an intermediate portion having an intermediate mass located generally in the space, at least one of the attachment means comprising an adhesive material of a type that provides an adhesive material bond having at least one of a tensile or shear bond strength which in force units is at least equal to 1/4 of the product of the mass of the intermediate portion of the flexible sheet times 1.0 g, whereby the adhesive material provides a barrier to smoke passing between the flexible sheet and the first structural element.
