1. A wall assembly comprising:
(a) a horizontal support structure comprising a lower surface;
(b) a header track attached to the horizontal support structure, wherein the header track comprises a web;
(c) a stud comprising an upper end received within the header track;
(d) a wallboard panel comprising a width, a top edge and an outer vertical surface, wherein the wallboard panel is positioned such that there is a gap between the top edge of the wallboard panel and the lower surface of the horizontal support structure, wherein the gap comprises a gap width that is equal to the width of the wallboard panel; and
(e) a framing accessory comprising
(i) a first leg comprising a fixed end and a free end, wherein the free end of the first leg is closer to the stud than the fixed end of the first leg,
(ii) a second leg oriented substantially perpendicular relative to the first leg, and
(iii) a strip comprising an upper surface, a bottom surface opposite the upper surface of the strip, an interior side surface that extends between the bottom surface of the strip and the upper surface of the strip, and an outer side surface opposite the interior side surface of the strip, wherein the bottom surface extends from the interior side surface to the outer side surface, wherein the entire bottom surface is attached to the first leg, wherein the strip comprises a material selected from the group consisting of open cell foam and closed cell foam,
wherein the first leg and the strip of the framing accessory are positioned in the gap between the top edge of the wallboard panel and the lower surface of the horizontal support structure such that the first leg is positioned vertically below the web of the header track, the gap is substantially filled by the first leg and the strip, the upper surface of the strip contacts the lower surface of the horizontal support structure thereby creating a seal between the strip and the horizontal support structure, and the second leg of the framing accessory is positioned along the outer vertical surface of the wallboard panel.
