The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, including but not limited to intumescent material. The fire-retardant material can be attached to the tracks such that the fire-retardant material expands and seals gaps and/or areas between the tracks and wall components such as ceilings, floors, and drywall.

1. A fire-retardant wall system, comprising: a horizontal ceiling element;a plurality of vertical wall studs;a header track for receiving the wall studs, the track connected to the horizontal ceiling element, the track comprising a web and at least one flange constructed from a unitary piece of metal, the flange extending from the web and having a first planar portion proximal the web and a second planar portion distal the web, the first planar portion having a first surface defined by the unitary piece of metal;at least one surface on the web for accepting a fire-retardant material strip thereon;at least a first fire-retardant material strip attached to the at least one surface on the web and configured to expand when exposed to elevated heat, the first fire-retardant material strip positioned between and contacting both the web and the horizontal ceiling element to create at least a substantial seal inhibiting the passage of air from one side of the track to the other side of the track through a gap between the horizontal ceiling element and the web when the fire-retardant material strip is in an unexpanded state;at least one piece of wallboard supported by the wall studs, wherein the at least one piece of wallboard supported by the wall studs is in direct contact with the first surface of the first planar portion of the flange, and wherein the second planar portion of the flange is recessed inwardly from the first portion, such that the at least one piece of wallboard supported by the wall studs is not in direct contact with the second portion. 2. The wall system of claim 1, wherein the first fire-retardant material strip is positioned at a corner between the web and the at least one flange. 3. The wall system of claim 2, wherein the first fire-retardant material strip extends outwardly beyond the corner such that an outermost edge of the first fire-retardant material strip is spaced outwardly of the first planar portion of the at least one flange. 4. The wall system of claim 1, wherein the web defines a recess and the first fire-retardant material strip is positioned in the recess. 5. The wall system of claim 1, further comprising a plurality of fasteners, wherein each one of the plurality of fasteners attach one of the plurality of studs to the track, wherein the plurality of fasteners are located within the second planar portion of the at least one flange. 6. The wall system of claim 5, further comprising a plurality of vertical slots formed within the second planar portion and spaced along a length of the track, wherein each one of the plurality of fasteners is passed through one of the plurality of vertical slots. 7. The wall system of claim 1, further comprising a second fire-retardant material strip positioned on an interior surface of the first planar portion. 8. A fire retardant wall system, comprising: a horizontal ceiling element;a plurality of vertical wall studs;a header track for receiving upper ends of the wall studs, the track connected to the horizontal ceiling element, the track comprising a web portion, a first flange and a second flange extending in the same direction from opposing side edges of the web portion the web portion and the flanges constructed from a unitary piece of metal, the header track defining an exterior surface and an interior surface, each of the first flange and the second flange having a planar proximal portion and a planar distal portion, the proximal portion being closer to the web than the distal portion and the distal portion containing a free end of a respective one of the first and second flanges, the proximal portion further having a first surface defined by the unitary piece of metal wherein a first distance is defined between the proximal portions of the first and second flanges and a second distance is defined between the distal portions of the first and second flanges, wherein the first and second distances are taken in a direction substantially parallel to the web and perpendicular to the side edges of the web, wherein the first distance is greater than the second distance, wherein the free ends of each of the first and second flanges define an opening that is equal to the second distance, at least one fire-retardant material strip secured to a surface of the header track;at least one piece of wallboard supported by the wall studs, wherein the at least one piece of wallboard supported by the wall studs is in direct contact with the first surface of the proximal portion of one of the first and second flanges, and wherein the distal portion of the one of the first and second flanges is recessed inwardly from the proximal portion such that the at least one piece of wallboard supported by the studs is not in direct contact with the distal portion. 9. The wall system of claim 8, wherein the at least one fire-retardant material strip is secured to an interior surface of the proximal portion of one of the first and second flanges. 10. The wall system of claim 8, wherein the at least one fire-retardant material strip is secured to the web portion. 11. The wall system of claim 8, wherein the at least one fire-retardant material strip comprises a first strip and a second strip, wherein the first strip is secured to an interior surface of the proximal portion of one of the first and second flanges and the second strip is secured to the web portion. 12. A track adapted for use in a fire-retardant wall system, comprising a web portion, a first flange and a second flange extending in the same direction from opposing side edges of the web portion and spaced from one another a sufficient distance to receive an end of a wall stud therebetween, the track defining an exterior surface and an interior surface, at least one of the web portion, first flange and second flange comprising a plurality of openings extending therethrough, at least one fire-retardant material strip secured to the interior surface of the track such that it covers at least a portion of each of the plurality of openings. 13. The track of claim 12, wherein the at least one fire-retardant material strip covers an entirety of each of the plurality of openings. 14. The track of claim 12, wherein the plurality of openings and the at least one fire-retardant material strip are provided on one of the first and second flanges. 15. The track of claim 12 wherein at least one of the web portion, the first flange and the second flange further comprise a plurality of fastener slots extending therethrough such that the at least one fire-retardant material strip does not cover the fastener slots.
