Wall joint or sound block component and wall assemblies

A method of making a component for placement in a wall gap, comprising:

• forming an elongate profile comprising a first leg and a second leg that cooperate to form an L-shape in cross-section and a flexible enclosure defining an interior space, wherein the flexible enclosure comprises a pair of flexible legs;
• positioning a blocking member within the interior space of the flexible enclosure;
• and
• separating the flexible legs and inserting the blocking member into the interior space between the flexible legs.

An elongate component for placement within a deflection gap between an upper surface and an edge of a wallboard in a head of wall assembly, the component comprising:

• a wall-face leg configured to extend along an outer face of the wallboard;
• a wall-end leg configured to extend along the edge of the wallboard, the wall-end leg being oriented perpendicular to the wall-face leg;
• a flexible gap portion configured to be positioned within and extend along the deflection gap, the flexible gap portion extending in an opposite direction from the wall-face leg on an opposite side of the wall-end leg relative to the wall-face leg, the flexible gap portion configured to flex to vary a vertical dimension as a height of the deflection gap varies between an open position and a closed position;
• a blocking element located in a space defined by the wall-end leg and the flexible gap portion, the blocking element configured to block fire and/or sound within the deflection gap;
• wherein at least a portion of the flexible gap portion is located on an exterior side of the blocking.
