The invention provides a cellular polyurethane foam composition for forming a cellular ceramic under fire conditions, the composition comprising: at least 40% by weight based on the total weight of the composition of a polyurethane; from 10% to 40% by weight based on the total weight of the composition of silicate mineral filler; from 5% to 20% by weight based on the total weight of the composition of at least one inorganic phosphate that forms a liquid phase at a temperature of no more than 800° C.; from 0.1% to 10% by weight based on the total weight of the composition of a heat expandable solid material; and wherein the total proportion of inorganic components constitutes in the range of from 20% to 60% by weight of the total composition.
