A composite insulator is formed having evacuated hollow plastic enclosures arranged in a closely packed configuration with a foamed plastic resin filling the interstice between the plastic enclosures. According to a preferred aspect of the invention, hollow evacuated spheres are embedded into a matrix of polyurethane foam. The composite insulator can be formed directly within an insulating cavity of an appliance or can be formed into customized panels which can be inserted into an appliance. Also, disclosed is a method of manufacturing the composite insu...


A method of making an insulating wall comprising the steps of blowing a glass sphere having an inside surface, an outside surface and a tubular neck portion, introducing a metered amount of a thermoplastic resin into said sphere, evacuating gas from the glass sphere through said neck portion to create at least a partial vacuum in said sphere, heating and fusing said neck portion adjacent said sphere to seal said sphere while the said sphere is subjected to said vacuum, heating said sphere and rotating said sphere about two mutually perpendicular axes to ...
