THERMAL BROKEN GLASS SPACER ABSTRACT OF THE DISCLOSURE An improved insulating spacer assembly for reducing heat transfer between panes of an insulated glazing unit comprises an extruded or roll-formed hollow metal spacer together with thermal breaks and primary sealant. The spacer and thermal breaks are preferably coextruded together, with the thermal breaks being extruded along the upper third portion of the spacer sidewalls, lengthwise along the spacer sidewall. The primary sealant is extruded along the middle third of the spacer sidewalls, parallel to and in cohering relationship to the thermal breaks. The invention also provides insulated glazing units wherein the spacer assembly is sandwiched between two glass panes to provide an exterior channel which is filled with a secondary sealant composition which also covers the exposed edges of the glass panes.
