Abstract: A privacy wall for joining a floor and ceiling, which wall includes a lower panel projecting upwardly from the floor, and a privacy panel extending vertically between the ceiling and the upper edge of the lower panel. The privacy panel has upper and lower edges supported within retainers confined within recesses defined by support tracks. The upper and lower retainers are identical but reversely vertically oriented relative to the respective recesses. Each retainer includes a central base wall and pairs of first and second legs projecting outwardly in opposite directions to define first and second oppositely oriented channels which accommodate the edge of the privacy panel therein. The first legs are short and inclined inwardly so that the lower edge of the panel can be sealingly accommodated therebetween. The second legs are of greater length and have sideward flanges adjacent the ends thereof.
