ABSTRACT:
The present invention is directed toward fire-rated wall construction components for use in building construction. The invention provides wall components and systems which have fire-retardant characteristics, as well as wall components which allow for needed ventilation in a building throughout times when no fire is present. Embodiments include tracks for holding studs which incorporate various geometries capable of receiving intumescent material. When the intumescent material becomes hot, it expands rapidly and fills its surrounding area, blocking fire, heat, and smoke from traveling to other areas of a building.
