Abstract: A fire barrier for use in dynamic voids to seal against the spread of fire. Flexible foil-backed insulation material is supported by a woven metallic support screen positioned in the void. As the surfaces defining the void undergo relative movement, the ability of the individual wire elements of the screen to move in a scissor-like fashion relative one another allow the screen to distort laterally without shearing, wrinkling, or buckling while the insulation material floating thereon is effectively isolated from any shear forces. The foil backing allows the insulation to freely shift relative the support screen.

Abstract: A barrier system provides protection for isolators from fire and heat. Insulative panels are positioned about said isolator and are attached thereto and to one another in such a manner so as to allow the isolator to distort without compromising the barrier's ability to effectively shield the isolator.

Abstract: A fire barrier for use in dynamic voids to seal against the spread of fire. Flexible barrier material is suspended below a lazy tong arrangement spanning the void while the edges of the barrier material are biased against the walls of the joint to provide the necessary seal.
