1. A fire retardant barrier fabrication process, comprising:
adhering a first layer comprising a metalized film to a second layer comprising a heat treated aluminized fiberglass cloth;
spreading a heat resistance adhesive between the first layer metalized film and the second layer heat treated aluminized fiberglass cloth;
adhering a third layer comprising intumescent paper to a back side of the heat treated aluminized fiberglass cloth with a polyurethane adhesive;
applying a heat resistance adhesive to a fourth layer material comprising a second metalized film;
adhering the fourth second metalized film to the third layer intumescent paper; and
wherein the adhered first, second, third, and fourth layers form a multi-layered fire-resistant barrier laminate configured to be applied to building materials.
