Abstract:
1. Multi-dimensional fire barriers shaped for use in multi-dimensional architectural expansion joints comprising a plurality of fire resistant material layers, comprising: a) at least one intumescent layer; b) at least one insulating layer having a length, a width, a first lateral surface, and a second lateral surface; c) at least one mechanical support layer having a length, a width, a first lateral surface, and a second lateral surface, d) said width of said mechanical support layer being greater than said width of said insulating layer; e) said intumescent layer positioned against said first lateral surface of said insulating layer; and f) said mechanical support layer positioned against said second lateral surface of said insulating layer so that the width of said mechanical support layer is parallel to but extends beyond the width of said insulating layer, g) said mechanical support layer, said insulating layer, and said intumescent layer affixed together providing for a multi-dimensional fire barrier configured for fitting an L-shaped expansion joint that occurs at junctions formed by the confluence of at least one wall and a floor or by the confluence of at least one wall and a ceiling, wherein said fire barrier configuration described as: each of said flanges providing means for attaching said shaped fire barrier to a building unit.
