Abstract
Vertical and/or horizontal frame members for use in a curtain wall construction including a framework and one or more glazing panels include a pair of elongated, spaced apart, metal elements structurally interconnected with a heat insulating element. One of the elements is formed with a pocket having an opening in a wall portion facing the other metal element and the other metal element includes a tongue extending into the pocket through the opening. The heat insulating element of resinous plastic material structurally interconnects the tongue and pocket of the metal elements into a composite frame member and provides a heat insulating thermal barrier therebetween.
