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.
Claims21
A wall assembly comprising:
- a. a horizontal support structure comprising a lower surface;
- b. 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;
- and
- c. a framing accessory comprising
- (i) a first leg comprising a first leg width, wherein the first leg width is greater than or equal to the width of the wallboard panel,
- (ii) a second leg oriented substantially perpendicular relative to the first leg, and
- (iii) a strip 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 framing accessory is positioned within the wall assembly such that the first leg is above the top edge of the wallboard panel and vertically spaced apart from the lower surface of the horizontal support structure, 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.

A wall assembly comprising:
- (a) a horizontal support structure comprising a lower surface;
- (b) 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
- (c) a framing accessory comprising
- (i) a 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 framing accessory is positioned within the wall assembly such that the first leg is vertically spaced apart from the lower surface of the horizontal support structure resulting in a portion of the gap extending from an exterior surface of the first leg to the lower surface of the horizontal support structure, the portion of the gap extending from the exterior surface of the first leg to the lower surface of the horizontal support structure is substantially filled by the strip, 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.
