Abstract: A firewall system includes a wall stud; a wall covering; and an expansion furring. An expansion furring can have a top having first and second top edges; a side, having a side edge, and extending from one of the first and second top edges; and a furring flange, extending from the side edge, and being formed of one or more deformable materials. The furring flange can be attached to the wall stud and to the wall covering with the expansion furring being disposed between the wall stud and furring. The furring flange absorbs, via deformation, at least a portion of movement of the wall stud due to heat-based expansion of the wall stud.

Abstract: An expansion bracket absorbs movement of a wall stud to prevent damage to a wall covering attached to the wall stud. The expansion bracket can include a main body having a main body flange, formed of a deformable material, and having a wall stud attachment end configured to attach to the wall stud via a wall stud attachment element. The main body can also have a furring attachment element configured to attach a furring to the main body. When the main body is attached to the wall stud and the furring, and the wall covering is attached to the furring via a wall covering attachment element, the main body flange is configured to absorb, via deformation, at least a portion of the movement of the wall stud due to heat-based expansion of the wall stud.

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.
