A multi-panel glazing unit (12) comprising a transparent, fluid sol and at least two transparent sheets (16) of glazing material spaced apart to enclose the fluid sol (20), the sol wetting the inner surfaces of the glazing sheets and being thermally convertible to a cellular, non-flammable, inorganic material that adheres to the inner surfaces of the glazing sheets and that insulates against heat transfer. In an embodiment, the sol comprises a polar solvent, an aluminum compound, and a compound reactive with the aluminum compound under thermal influence to form an aluminous crystalline material. <IMAGE> |
