Insulative compositions are prepared by agitating an aqueous mixture of aerogel and gelatin. Insulation obtained with such methods is non-toxic, environmentally safe, fire resistant with low smoke, has good handling properties, and provides low thermal conductivities. The insulation can be made in sheets, loose fill, or can be molded into particular shapes to provide particular types of insulation such as pipe insulation.

[ What is claimed is:] [1.] A process for making a thermally insulative foamed composition which comprises combining aqueous gelatin and particles of an inorganic, hydrophobic aerogel to form a mixture, agitating the mixture to form a wet foam, and drying the wet foam, wherein the gelatin is present at an amount of at least about 2% by dry weight, the said gelatin having a minimum Bloom of at least about 60, and the aerogel being present at an amount of at least about 5% by dry weight, wherein further there is a sufficient amount of water in the mixture to wet the hydrophobic aerogel and also allow the mixture to foam.
