A louvered ceiling construction especially suited for parabolic louvers is claimed. Runners, of the same hollow channel shape as the louver members, are provided with openings into which extensions carried by the louver members are secured. The extensions are entirely concealed within the channels so that a smooth and uniform appearance is presented from below.
An improved louvered ceiling construction is disclosed in which louver channel members are suspended from runner channel members by means of outwardly bent tabs on the ends of the channel members. The tabs are inserted behind widened slots in the runner. The runner slots are overlapped entirely by the tabs and louver channel interior so that leakage of light is prevented.
