Abstract: A portable gas grill features a combination of quick heat up and quick cool down in a compact and truly portable self contained grill for camping, tailgating, and other activities. The gill includes a lower housing containing a multilayer metal foil insulation/reflector member, a grill surface, a radiant heating element, and a grill cover with a multilayer metal foil insulating/reflector member. The radiant heating element utilized in the gas grill includes a gas jet burner in combination with a heat radiating tube which contains the flame extending from the jet burner. The radiant heat generated by the radiant heating tube heats a grill surface of 170 square in. or greater to adequate grilling temperatures such as 700° F. and higher.

Abstract: The invention provides a grill configuration which enables a 2400 Watt or smaller electric heating element to provide cooking temperatures of at least 500.degree. F. when food is present on a grill area of at least 200 square inches. The electric grill includes an electric heating element and a multilayer metal sheet insert shaped to reflect radiation heat from the heating element to impinge on the food present on the grill surface. The multilayer metal sheet insert is preferably metal foil layers which provide maximum insulation and heat containment to increase the efficiency of the limited heat available from the electric heating element of the grill.

Abstract: A multilayer metal sheet-polymer composite wherein the multilayer metal sheet side provides heat resistance and heat protection for the polymer side. The multilayer metal sheet component preferably comprises aluminum or stainless steel foils bonded to the polymeric component to form articles such as, conduits, panels, equipment housings and cooking devices.
