Insulative Metallic Channel And Construction Assembly

US Patent:
8307610, Nov 13, 2012
Filed:
May 25, 2010
Appl. No.:
12/786807
Inventors:
LeRoy A. Landers - Portland OR, US
International Classification:
E04C 3/00
US Classification:
52846, 524811, 52144, 524831
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.

Thermally-Improved Metallic Framing Assembly

US Patent:
5592796, Jan 14, 1997
Filed:
Dec 9, 1994
Appl. No.:
8/353090
Inventors:
LeRoy A. Landers - Philadelphia PA
International Classification:
E04B 260
E04C 332
US Classification:
52241
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].
