A fire-retardant, intumescent laminate system suitable for application to combustible or heat-sensitive substrates comprises an intumescent layer which is a porous sheet material, e.g., paper or foams saturated with an intumescent composition and having a flexible protective layer adhered to the intumescent layer. The intumescent laminate system may include a vapor barrier layer, e.g., aluminum foil and/or a thermal barrier layer, e.g., glass wool or cardboard adjacent to the intumescent layer, and is particularly suitable as a protective, fireretardant overlay on thermally delicate substrates such as organic foams, e.g., polystyrene.

An intumescent, fire retardant laminate system for application to a substrate to be protected from fire and heat comprising a. an intumescent layer comprising at least one porous cellulosic sheet material selected from tHe group consisting of paper and fabric, impregnated with a water-soluble intumescent composition consisting essentially of 1. a heat-curable amino-aliphatic aldehyde condensation product as a resinous carbonific, 2. a non-resinous carbonific selected from the group consisting of carbohydrates and polyhydroxy alcohols, and 3. a spumific selected from the group consisting of monoammonium phosphate, di-ammonium phosphate, phosphoric acid, ammonium sulfate, ammonium bromide, sodium tungstate and mixtures thereof; and b. a flexible, protective layer adhered to the outer surface of said intumescent layer, said protective layer being selected from the group consisting of organic thermoplastic resin layers and metallic foils. A fire retardant laminate comprising: a. an organic polymeric foam to be protected from fire and heat, b. at least one intermediate barrier layer selected from the group consisting of a thermal barrier layer and a vapor barrier layer adhered to said foam, said thermal barrier layer consisting essentially of at least one heat insulative material that is thermally stable at least up to 200°C selected from the group consisting of mineral wool, glass wool, inorganic cements, expanded vermiculite, expanded perlite, wood, cardboard, cellulosic webs, and asbestos paper; and said vapor barrier layer consisting essentially of at least one vapor impermeable material that is thermally stable at least up to 200°C selected from the group consisting of metallic foils; and synthetic plastic films; and c. an intumescent layer adhered to said intermediate barrier layer, said intumescent layer comprising at least one porous cellulosic sheet material selected from the group consisting of paper and fabric, impregnated with a water-soluble intumescent composition consisting essentially of 1. a heat-curable amino-aliphatic aldehyde condensation product as a resinous carbonific, 2. a non-resinous carbonific selected from the group consisting of carbohydrates and polyhydroxy alcohols, and 3. a spumific selected from the group consisting of monoammonium phosphate, di-ammonium phosphate, phosphoric acid, ammonium sulfate, ammonium bromide, sodium tungstate and mixtures thereof; and d. a flexible, protective layer adhered to the outer surface of said intumescent layer, said protective layer being selected from the group consisting of organic thermoplastic resin layers and metallic foils.
