ABSTRACT:
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 plastic insulating elements which thermally isolate the metal spacer from the panes of glass while permitting conventional application of the sealant to provide reliable bonding. On 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. In an alternative design the plastic insulator comprises extruded plastic strips which are attached through grooves in the metal spacer. In both designs the height of the insulating contact element can be selected to correspond to the desired gap width between the two glass plates.
