Multi-layer fire-rated joint component

A fire-rated head-of-wall assembly, comprising:

• a header track configured to be coupled to a ceiling surface, the header track having a web and first and second flanges extending from the web in a first direction, wherein each of the first and second flanges is substantially planar such that the header track defines a substantially U-shaped cross section;
• at least one stud coupled with the header track, an upper end of the stud located between the first and second flanges;
• a wallboard coupled to the stud, an upper end of the wallboard overlapping the first flange of the header track;
• a deflection gap formed between the upper end of the wallboard and the ceiling surface, the deflection gap being variable between a closed position and an open position;
• a fire-blocking gasket comprising:
• a first layer comprising a vinyl profile, the vinyl profile having a vertical portion and a horizontal portion at least partially defining an air gap, the horizontal portion including an upper flange;
• and
• a second layer comprising an intumescent material;
• wherein the vertical portion of the vinyl profile is coupled to the first flange of the header track and positioned between the first flange and the wallboard, the upper flange contacts the ceiling surface and is positioned at least partially within the deflection gap in the open position, the upper flange slidingly engages with the first flange of the header track, and the upper flange and the horizontal portion fold towards the vertical portion of the first layer and collapse the air gap as the deflection gap narrows towards the closed position;
• wherein the vinyl profile is configured to at least partially melt and the intumescent material is configured to at least partially expand to seal the deflection gap above a first temperature.

A fire-rated head-of-wall assembly, comprising:

• a header track having a web and first and second flanges extending therefrom, the header track coupled with a ceiling surface;
• at least one stud coupled with the header track;
• a wallboard coupled to the stud, an upper end of the wallboard overlapping the first flange of the header track;
• a deflection gap formed between the upper end of the wallboard and the ceiling surface, the deflection gap being variable between a closed position and an open position;
• a fire-blocking gasket comprising:
• a first layer comprising a profile including an upper flange, the upper flange slidingly engaged with the header track and at least partially defining an air gap;
• and
• a second layer comprising an intumescent material;
• wherein the profile is coupled to the first flange of the header track and the upper flange contacts the ceiling surface to provide a seal across the deflection gap;
• and
• wherein the upper flange is configured to fold towards a vertical portion of the profile to collapse the air gap as the deflection gap transitions towards the closed position.
