Abstract
Multi-dimensional, multi-layered, fire barriers for use in multi-dimensional architectural expansion joints may comprise a plurality of fire resistant material layers and the method for making such barriers is taught. The layers comprising the fire barriers may be connected together by stitching with high temperature thread, by stapling, by pins and bolts, by adhesive, or by any other bonding method. The fire barriers may be designed, for example, for use in a corner junction expansion joint, in a 'T'-shaped expansion joint, or in a 4-way expansion joint, for example. A fire barrier may comprise: at least one protective and mechanically supporting layer; at least one insulating layer, and at least one layer of intumescent material, wherein the insulating layer is disposed between the mechanical support layer and the intumescent layer. The fire barriers may be provided completely ready to install or ready to assemble, as desired.
