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.
Claims3
An elongated, composite, structural, insulated frame member comprising:
- a pair of elongated metal elements interconnected by an element of heat insulating material;
- one of said metal elements including an elongated pocket having an opening facing the other metal element,
- the other of said metal elements including an elongated tongue extending into said pocket through said opening, and
- said heat insulating element comprising a solid, non-porous, hardened plastic material, self-bonded to and disposed between adjacent facing surfaces of said pocket and said tongue for structurally interconnecting said metal elements forming a composite insulating frame member, said other member including a wall member forming a wall for at least one glazing recess removably interconnected with said tongue.
