A composition for insulation which may be used for reducing thermal transmission, for absorbing sound waves and for providing a fire spread barrier, and which may be sprayed on surfaces in relatively thick coats. The composition includes a blended mixture of cellulose fiber, mineral wool, boric acid and expanded silicate glass. The blended fibers are mixed with an adhesive and sprayed on a surface to be insulated, and the adhesive preferably is a fire retardant, nontoxic adhesive which remains flexible after it has dried so that expansion or contraction of the insulation or the insulated surface will not result in cracks in the insulation.

A building insulation comprising thirty-five percent (35%) to fifty-three percent (53%) by weight of cellulose fiber, three percent (3%) to five percent (5%) by weight of an acid-containing fire retardant for reducing the flammability of said cellulose, seven percent (7%) to nine percent (9%) by weight of expanded silicate glass for reducing the corrosive effect of said acid-containing fire retardant, and thirty-five percent (35%) to fifty-three percent (53%) by weight of mineral wool.
