Abstract
A fire-rated component for a fire-rated joint, such as a head-of-wall assembly, includes an elongate body having at least a first layer, which can be in the form of a polymer profile. A second layer can be or include a foil lining and a third layer can be or include an intumescent material. The elongate body, such as the first layer, defines an air gap. The foil lining and/or the intumescent material can be positioned within the air gap. A planar lower portion of the first layer of the elongate body is positioned between a header track and a wallboard in the fire-rated joint. A non-planar upper portion of the first layer of the elongate body is positioned at least partially within a deflection gap of the wall assembly and sealingly engages the ceiling.
