Abstract
A framing accessory includes a bead and a backing strip. The bead may comprise a first leg, a second leg, and a lip. The second leg may comprise a plurality of openings. The strip may be attached to the upper surface of the first leg. In some embodiments, the strip may comprise a single layer of material, while in other embodiments, the strip may comprise two or more layers of material. The strip may comprise material having fire resistant, intumescent, and/or sound insulating properties. The finishing accessory may be configured to be installed in a gap at a head of wall joint by positioning the first leg and strip along the top edge of a wallboard panel and the second leg extending vertically downward along the outer surface of the wallboard panel.
Claims26
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 an exterior surface, an interior surface opposite the exterior surface, a fixed end, and a free end opposite the fixed end of the first leg,
- (ii) a second leg oriented substantially perpendicular relative to the first leg, wherein the second leg comprises a plurality of openings defined therein, and
- (iii) a strip comprising a material selected from the group consisting of open cell foam and closed cell foam, wherein the strip comprises
- 1. a bottom surface, wherein the entire bottom surface is attached to the exterior surface of the first leg,
- 2. an upper surface opposite the bottom surface of the strip,
- 3. an interior side surface that extends between the bottom surface of the strip and the upper surface of the strip, and
- 4. an outer side surface opposite the interior side surface of the strip, wherein the strip extends at least to the free end of the first leg, wherein the framing accessory comprises a first height that extends from the interior surface of the first leg to the upper surface of the strip, wherein the first height of the framing accessory is at least 0.375 inches, wherein the bottom surface extends from the interior side surface to the outer side surface,
- wherein the framing accessory extends longitudinally between a first end and a second end, wherein the first leg is solid adjacent to the first end of the framing accessory,
- 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.
