ABSTRACT:
The process of making a fire-retardant insulation barrier provides a single step of applying an emulsion comprised of aluminum trihyridate and polyvinylchloride to one side of a foamed molded or extruded or fabricated polystyrene board. After the emulsion dries to a coating, the board can be shipped. The aluminum trihydrate and polyvinylchloride are in a ratio of approximately 4 to 1 to 1 to 4 and the emulsion is applied at a wet weight of 1 to 6 pounds per 32 square feet of board area.
