Abstract

The embodiments disclose 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.

Claims (42)

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.

2 . The fire retardant barrier fabrication process of claim 1 , wherein the multi-layered fire-resistant barrier laminate has a weight between 650 grams/square meter and 1,000 grams/square meter.

3 . The fire retardant barrier fabrication process of claim 1 , wherein the metalized film has a thickness range from 7 microns to 25 microns.
