  • Thermally insulated composite frame member and method for the manufacture thereof
    Patent number: 5617695
    Abstract: A composite thermally insulated architectural frame member is provided which is comprised first metal section, a second metal section and a preformed thermal break section. The first metal section has a longitudinal inner channel. The second metal section has an extension positioned within the channel of the first section in a predetermined spaced apart relationship from the first metal section. The second metal section is positioned in a longitudinal channel in the thermal break section in a spaced apart relationship from the first metal section.
