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.
Claims14
A fire barrier system for sealing a dynamic void between architectural structures, comprising:
- a metallic support screen spanning said void, a portion of said screen affixed to at least one of the architectural structures;
- and
- insulation material non-rigidly coupled to and supported by said support screen in a free-floating manner such that said insulation material is substantially isolated from sheer forces resulting from relative movement between the structures.
A fire barrier system for sealing a dynamic void, comprising:
- a loosely woven stainless steel screen spanning said void and rigidly affixed to the edges of said void;
- a layer of stainless steel foil positioned over said screen in a free floating manner, said foil being narrower than said screen, the foil non-rigidly coupled to the screen;
- and
- refractory matting of substantially the same width as said foil positioned over said foil.
