ABSTRACT:
An improved bottom track for a stud wall assembly which includes a generally U-shaped channel member including two juxtaposed side wall portions connected at ninety degree angles to a base wall portion. A factory-installed elongated rectangular strip of a fire retardant material, such as caulking, extends along the length of each side wall. In use, the bottom track is secured in a conventional manner to the floor structure, through the base wall portion of the U-shaped channel member. Screws extending through the side walls of the channel member secure the channel member to a plurality of studs. Wall panels, such as dry wall, are attached to opposite lateral faces of the studs. The lower portion of the wall panels vertically overlap the fire retardant strips to create a continuous fire barrier from the wall panels to the floor substrate.
