Fire resistant barrier for dynamic expansion joints

A fire resistant barrier system comprising a fire resistant barrier and at least one radiation heat shield, wherein said fire resistant barrier comprises a first mechanical support layer having a first and second major surface;

• a second layer having a first and second major surface, wherein said second layer provides protection and mechanical support to the fire barrier;
• and at least one layer of intumescent sheet having a first and second major surface, wherein said at least one layer of intumescent sheet is disposed between said first mechanical support layer and said second layer;
• wherein said first mechanical support layer, said second layer and said at least one layer of intumescent sheet are locally bonded together only substantially along a longitudinal center and substantially continuously along the length of said layers;
• and wherein said at least one radiation heat shield comprises a plurality of fire resistant material layers comprising at least one layer of inorganic fibrous mat material having a first and second major surface encapsulated by two separate layers of metalized, inorganic fiber reinforced polymeric material.

A method for installing an architectural expansion joint fire barrier comprising:

• providing a fire resistant barrier comprising a plurality of fire resistant material layers comprising a first mechanical support layer material having a first and second major surface;
• a second layer having a first and second major surface, wherein said second layer provides protection and mechanical support for the fire barrier;
• and at least one layer of intumescent sheet having a first and second major surface, wherein said at least one layer of intumescent is disposed between said first mechanical support layer and said second layer;
• wherein said first mechanical, said second, and said intumescent sheet layers are locally bonded together only substantially along a longitudinal center and substantially continuously along the length of said layers;
• and
• affixing said fire barrier to a building structure.
