Abstract: A three dimensional flame barrier is described herein. The three dimensional flame barrier comprises a flame resistant material, wherein the flame resistant barrier has a complex geometry that is defined by a height, width and length, wherein the height of the complex geometry is substantially greater than the thickness of the flame resistant material from which it is formed wherein the flame resistant material comprises inorganic fibers, inorganic particles and an inorganic binder. In some embodiments, the flame barrier article can further comprise a fire protection coating disposed on a first major surface of the flame barrier material.
