A method of fabricating a thermal pane window or door and the product so produced. The method comprises assembling at least two panes of glass in spaced parallel relation to each other, defining a space therebetween and separated all around the edges by a metal spacer frame, and electrostatically bonding the frame to its adjacent panes in the presence of heat and pressure. The resultant thermal pane window or door is characterized by a hermetically sealed space between the two panes of glass that preferably has been evacuated so as to contain no moisture and oxygen and then preferably is filled with a low heat-loss gas or left under vacuum.

A method of fabricating a thermal pane window comprising: (a) providing an assembly of at least two panes of glass in spaced parallel relation to each other so as to define a space therebetween and separated all around the edges by a metal spacer frame; (b) inserting a spacer electrode within said metal spacer frame; (c) roll bonding said assembly all around said edges by concurrently applying heat and pressure to one point at a time along said edges while passing an electric current across the glass-metal, glass interfaces at said one point, said pressure being applied to said one point being about 1000 p.s.i., said roll bonding said assembly hermetically sealing said space between said panes of glass; (d) evacuating said hermetically sealed space to about one torr or less; and (e) sealing off said evacuated space. A thermal pane window exhibiting no corrosion and condensation characteristics despite prolonged use comprising: (a) at least two panes of glass in parallel spaced relation to one another and separated by a thin metal spacer frame said spaces offset from the edges of said panes of glass along opposed interfaces formed between said spacer frame and said panes of glass, said spacer frame being electrostatically sealed to said panes of glass along said opposed interfaces hermetically sealing the space between said panes, said metal spacer frame being formed of aluminum alloy, and a plastic material disposed in and occupying the space between said panes of glass outwardly of said thin metal spacer frame toward the edges of said panes of glass, said plastic material provides structural strength and rigidity to said thermal pane window; and (b) a low heat-transfer gas devoid of oxygen and moisture contained within said space, said low heat-transfer gas being selected from the group including argon, krypton, and Freon R-12.
