Abstract
Fire or sound blocking components are configured to resist the transmission of fire, heat or sound through a gap in a wall assembly. The components can be elongate and have a profile of a consistent cross-sectional shape along the length of the component. In some arrangements, the component is configured to provide fire or sound blocking to a dynamic head-of-wall joint of a wall assembly. In other arrangements, the component is configured to provide fire or sound blocking to a reveal gap within or along an edge of a wall assembly.
Claims23
A fire-blocking element, comprising:
- a profile, comprising:
- a first leg;
- a second leg comprising a terminal free edge and an inner end, the first leg connected with the inner end of the second leg to form a generally L-shaped structure in cross-section, the first leg is configured to extend along an outward-facing surface of wall board of a wall in use, the second leg is configured to extend along an upper end surface of the wall board in use, the first leg comprises an array of openings configured to receive joint compound;
- a gasket element having an apex surface configured to contact an overhead structure associated with the wall in use, wherein the gasket element is compressible to conform to an irregular surface of the overhead structure;
- a fire-blocking material strip located on the second leg of the profile, the fire-blocking material strip directly attached to an upper surface of the second leg of the profile;
- wherein the gasket element is located along the profile between the fire-blocking material strip and the first leg.

A fire-blocking element, comprising:
- a profile comprising a first leg having an inner end and terminating in a free edge and a second leg having an inner end and terminating in a second free edge, the inner end of the first leg fixed with the inner end of the second leg to form a generally L-shaped structure when viewed from the end or in cross-section, the first leg is configured to extend along an outward-facing or exposed surface of wall board of a wall in use, the second leg is configured to contact and extend along a free upper edge of the wall board in use, and the first leg is configured to be covered by joint compound;
- a gasket element disposed on an exterior surface of the second leg and configured to contact a ceiling or other overhead structure associated with the wall, wherein a wall of the gasket element is compressible so that the gasket element can conform to the ceiling or other overhead structure;
- wherein the second free edge of the second leg defines an upturned kickout that has a free end and is more flexible than a remainder of the second leg such that the upturned kickout is configured to create a seal with an adjacent structure of the wall, the upturned kickout extending away from the first leg and in the same direction as the gasket element.
A fire-blocking element, comprising:
- a profile, comprising:
- a first leg;
- a second leg comprising a terminal free edge and an inner end, the first leg connected with the inner end of the second leg to form a generally L-shaped structure in cross-section, the first leg is configured to extend along an outward-facing surface of wall board of a wall in use, the second leg is configured to extend along an upper end surface of the wall board in use, the first leg comprises an array of openings configured to receive joint compound;
- a gasket element having an apex surface configured to contact an overhead structure associated with the wall in use, wherein the gasket element is compressible to conform to an irregular surface of the overhead structure;
- a fire-blocking material strip located on the second leg of the profile, the fire-blocking material strip defining an exposed surface opposite a surface attached to an upper surface of the second leg of the profile, wherein the apex surface of the gasket element is spaced further from the second leg of the profile than the exposed surface of the fire-blocking material strip such that the exposed surface is configured not to contact the overhead structure in use;
- wherein the gasket element is located along the profile between the fire-blocking material strip and the first leg.
