An improved insulating spacer to reduce the heat transfer between the two panes of glass of double insulated glass comprises an extruded or roll-formed metal spacer together with a plastic insulating element which thermally isolates the metal spacer from the panes of glass while permitting conventional application of the sealant to provide reliable bonding. In one embodiment the plastic insulator comprises an extruded plastic overlay which fits tightly over part of a conventional metal spacer and has projecting contacts which abut the glass.

An insulating spacer for precision separation of plates in double insulated glass, comprising: a metal spacer for interposition between two glass panes, said metal spacer permitting conventional sealant bonding of the glass to the spacer, said metal spacer having a slot running the length thereof; and insulating means attached to said metal spacer to thermally isolate said metal spacer from the two panes of glass, thereby greatly reducing the heat transfer from one pane of glass to the other through the spacer, said insulating means comprising an elongated plastic element formed of unitary, generally U-shaped section fitting tightly to a portion of said metal spacer and fixedly attached thereto by friction, said insulating means covering at least a portion of the two sides of the spacer which contact the glass plates, said insulator having a series of small diameter holes extending therethrough and aligned with the slot running the length of said metal spacer, the legs of said U-shaped element being biased toward one another, said frictional engagement being provided by the body of said metal spacer forcing said legs apart.
