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].
Claims9
A thermally improved framing assembly, comprising:
- a planar wall component;
- a bottom metallic runner having a substantially flat face and at least one substantially flat flange extending transversely from said flat face;
- a metallic channel disposed transverse to said bottom metallic runner, said metallic channel comprising an elongated web and at least one elongated flange extending transversely from said web, said at least one elongated flange comprising first and second continuous ridges along the length of said at least one elongated flange which contact an inner edge of said at least one substantially flat flange of said bottom metallic runner and confront and support said planar wall component along first and second lines of contact transverse to said substantially flat face of said bottom metallic runner, and said at least one elongated flange further comprising an offset portion laterally spaced from said planar wall component, said offset portion extending between said first and second ridges approximately the entire width of said at least one elongated flange along the length of said metallic channel;
- and
- fastening means for connecting said planar wall component against said first and second ridges of said at least one elongated flange of said metallic channel, said fastening means extending through said planar wall component and said at least one elongated flange to rigidly connect said planar wall component to said at least one elongated flange so as to form a closed air pocket between said planar wall component and said offset portion of said at least one elongated flange which is bounded on either side by said first and second lines of contact formed between said first and second ridges and said planar wall component and which is bounded on one end by said bottom metallic runner.
