  • Insulative metallic channel and construction assembly
    Patent number: 8307610
    Abstract: An insulative metallic channel for supporting a construction assembly and resisting heat transfer includes an elongated web and at least one flange. The flange includes two ridges along the length of the flange and an inwardly-bent portion of the flange between the two ridges. The inwardly-bent portion extends between the two ridges approximately the entire width of the flange. An insulative material substantially fills the inwardly-bent portion of the flange.
    Type: Grant

  • Thermally-improved metallic framing assembly
    Patent number: 5592796
    Abstract: A thermally-improved metallic channel [50] having a web [60] with one or more flanges [62] extending at generally perpendicular angles therefrom. At least one of said flanges [62] incorporates an inwardly-bent depression [64]. This depression [64] forms contact ridges [66] that are used as bearing surfaces against which adjacent materials [56,58] may be affixed. These contact ridges [66] along with an air space [70] resulting from said inwardly-bent depression [64] serve to decrease the rate of heat loss or heat gain due to conductivity between said thermally-improved metallic channel [50] and adjacent materials [56,58].
