An elongate sheet metal body for attachment to the web of a grid tee, the body having a substantially right angle cross-section formed by legs that in use are vertical and horizontal, respectively, the vertical leg having a width adapted to fit against the web between a reinforcing bulb and lower flange of the tee, the horizontal leg having a width at least that of the width of a portion of the flange portion extending from the web to a free edge of the flange, the horizontal leg having at a free edge a plurality of depending lugs spaced uniformly from one another with a common center to center distance, the lugs having a horizontal width sized to fit into U-shaped baffles such that said baffles carried on said lugs have the same center to center distance as the lugs.

An isolating hanger and method of making is disclosed for mounting a ceiling from an upper support. The isolating hanger comprises a one piece bendable wire having a spring shape defined between a first and a second wire end. The spring shaped is tempered for transforming said spring shape into a resilient spring. The remaining bendable wire ends affix the upper support to the ceiling for isolating vibration between the ceiling and the upper support.

A ceiling system, comprising at least two elongate carriers, configured to support at least one ceiling panel; at least one elongate beam; and at least two connecting brackets; wherein each elongate carrier is supported at one or more suspension locations; each elongate beam is coupled to at least two elongate carriers by a respective connecting bracket; and the connecting brackets are coupled to the elongate carriers by a push-fit connection.

A folded architectural panel folded from a flat sheet, the panel having opposite longitudinal ends extending in a width direction, opposite lateral sides extending in a length direction and a depth perpendicular to the width and length directions. The panel includes a first downward fold adjacent one longitudinal end, extending in the width direction, and having opposite fold ends at the respective lateral sides of the panel; a second downward fold adjacent the other longitudinal end, extending in the width direction, and having opposite fold ends at the respective lateral sides of the panel; and a central upward fold at a central portion of the panel between the first and second downward folds; the first downward fold, the second downward fold and the central upward fold enable contraction of the opposite end folds towards each other to cause folding of the first and second end folds and an increase in the depth of the panel at the central portion. The panel further includes two pairs of respective side upward folds extending from the four opposite fold ends of the first and second end folds to the central upward fold such that, with contraction of the opposite end folds towards each other, a respective section of each respective lateral side between two respective fold ends contracts inwardly towards the opposite lateral side and a respective sidewall is formed on each respective lateral side of the panel extending from the respective pair of side upward folds in the depth direction.

A suspension system for a suspended ceiling includes, in an installed state, a primary profile which substantially extends in a first horizontal direction, one or more suspension elements for the suspension of the primary profile, a secondary profile which extends in a substantially second horizontal direction and which is configured to support ceiling plates, a coupling bracket for the coupling of the primary profile to the secondary profile. The coupling bracket includes a main body which couples to the primary profile; two coupling legs which extend from the main body and which connect to the secondary profile; and a positioning element which is configured to work with the primary profile to position the coupling bracket in relation to the primary profile.
