Abstract
A structural, thermal barrier, architectural extrusion incorporating a rigid backbone which is embedded with the thermal break material in order to minimize relative longitudinal movement between the thermal break material and the extrusion.
Claims17
An architectural component, comprising:
- elongate, spaced, parallel, first and second frame members each made of a material with a high thermal conductivity;
- a thermal barrier member extending between said frame members and made of a material with a low thermal conductivity;
- interconnecting means which includes cooperating structure on said first frame member and said barrier member for substantially rigidly interconnecting said first frame member and said barrier member, and which includes cooperating structure on said second frame member and said barrier member for substantially rigidly interconnecting said second frame member and said barrier member, said interconnecting means restraining movement of each said frame member relative to said barrier member;
- and an elongate backbone member substantially embedded in said barrier member and having at spaced locations therealong a plurality of first portions which are each in direct contact with said first frame member at spaced locations along said first frame member, said backbone member having between each adjacent pair of said first portions a second portion which is free of engagement with said first frame member.

A structural, thermal barrier, architectural extrusion, comprising:
- an inner, elongated, extruded aluminum frame section;
- an outer, elongated, extruded aluminum frame section, said inner and outer frame sections being positioned in parallel, adjacent, spaced-apart relation to each other and having opposed surfaces, each of said surfaces having upper and lower, longitudinally extending walls projecting therefrom toward the opposing surface, said upper and lower walls each having a flange at its free end which flange extends toward the other one of said upper and lower walls, said walls and flanges defining an undercut, substantially C-shaped cavity which opens toward the opposing surface;
- at least one elongated, sinuous wire slidably disposed in one of said cavities and extending lengthwise therein with the crests and troughs of said wire bearing against said upper and lower walls and said wire being located in said cavities inwardly from said flanges;
- a block of polyurethane resin thermal barrier material formed in situ in said cavities and extending between them to connect said inner and outer frame sections solely by said thermal barrier material, said thermal barrier material filling said one cavity and encapsulating the wire therein whereby to restrain movement of said polyurethane resin thermal barrier material relative to said inner and outer frame sections.
