A suspended ceiling comprising SUSPENDED metal runners in a horizontal plane, the runners each having a horizontal flange having an effective vertical thickness, a plurality of rectangular drywall sheets aligned crosswise to the runners and screwed to the flanges with ends of the drywall sheets forming butt joints midway between adjacent runners, boards overlying butt joints and adjacent flanges, the boards being substantially stiffer than the drywall sheets, whereby the drywall sheet ends are drawn up towards an upper level of the flanges when screwed against the overlying board so that a pseudo taper is formed on the drywall sheet ends.

A interior partition includes a suspended wall track system that includes suspended wall track frame that aligns and receives an interior wall material to create a non-load bearing wall structure. The suspended wall track system may further include a suspended wall track frame that is fitted within a suspended ceiling track hanging from a ceiling floor with an unobstructed interstitial spacing between the suspended ceiling track and the ceiling floor.

In a dropped ceiling assembly system elements are provided which include an elongate planar shelf held below an elongate spine. The shelf has lateral edges which can support edges of a ceiling tile resting thereon. This spine is configured to be held in position either adjacent to spines of other elements within a dropped ceiling or from above, such as by suspension wires passing through suspension holes in the spine. A compartment is provided on an underside of the shelf which is sized and shaped to receive and hold at least a portion of a loudspeaker therein. The loudspeaker mounting system is thus integrated into the shelf which also acts to hold ceiling tiles within a dropped ceiling.

The invention relates to a profiled section (10) for temperature-control of a room, said section having a receiving portion (20) for a piping system positioning aid (60), a sealing surface (15), formed at least at the side of the receiving portion (20), and at least one first support (30) for a sealing panel (200), the first support (30) being formed at the side of the receiving portion (20) and pointing in the opposite direction to the sealing surface (15). The invention also relates to a building element assembly (100) comprising a profiled section (10) of this type and to an associated use.

A lighting assembly is provided that includes a light fixture in combination with a support grid such as a drop ceiling t-bar. The light fixture can be configured to use a t-bar as the main form of support. The light fixture can be push-fit onto a t-bar or use a clip to join two or more portions of the light fixture to an installed t-bar. Once attached to the T-bar, the light fixture itself can provides support for a ceiling tile. Various embodiments are provided which achieve a variety of light distributions useful in typical illumination applications. Both recessed and suspended fixture types are achieved in various embodiments which are particularly well suited for LED lighting.

In accordance with certain embodiments, systems of lighting components feature multiple illumination panels each having a backing support and, secured thereto, multiple illumination elements. The illumination elements have shapes defined by arrangements of illumination unit cells may be assembled to illuminate an arbitrary two-dimensional area.

A manufactured interior wall finish system and a manufactured ceiling finish system are described.

A ceiling module and method of constructing the same, the ceiling module mountable on a suspended ceiling grid structure and including a plurality of elongate blade members, at least a part of faces of at least two blade members being substantially mutually opposed, at least one elongate cross member extending at least between at least two blade members such that the plurality of blade members are connected to form an arrangement; and at least one support member, releasably engageable with the suspended grid ceiling structure and associated with at least one of the blade members to support the plurality of blade members from the suspended ceiling grid structure.

Described herein is a coated building panel that comprises a side surface that is textured and exhibits a white and/or color. The building panel comprising an upper surface opposite a lower surface and a side surface extending between the upper surface and the lower surface, a coating applied to the side surface, the coating comprising an inorganic particle having a disk shape and an ionic dispersant comprising an ionic group that are present on a repeating unit and the ionic dispersant comprising at least two of the repeating units.

An acoustic insulation product includes a panel made of porous material, based on foam or fibres, including a first face, referred to as back face, intended to face towards a wall, and a second face, referred to as front face, situated on the opposite side to the back face, and a layer, referred to as backing layer, which adheres to or is linked or coupled at least in part to the back face of the panel made of porous material, the backing layer having an airflow resistance of between 5 kPa.Math.s/m and 20 kPa.Math.s/m.
