ABSTRACT:
A formed sheet metal stud having a flange on the opposite side of the wall from that which is exposed to a fire, which flange is formed by a double thickness of the sheet metal which is loosely folded, leaving a finite space between the two thicknesses to function as a chimney, providing a cooling effect on portions of the stud adjacent the highest temperatures of the fire. Small holes are formed in the outer face of the loosely folded flange to permit cooler air from the unexposed side of the stud to enter the void within the loosely folded flange, where the air rises and cools the stud, and/or they permit heated air rising within the void to escape.
