Suspended ceiling, a ceiling tile and an associated installation method

Abstract

In accordance with the present inventive concept, there is provided a suspended ceiling comprising a ceiling tile ( 500 ) and a grid of profiles forming a frame which supports the ceiling tile ( 500 ). The ceiling tile ( 500 ) has a first and a second pair of non-adjacent side-edge portions, wherein the grid of profiles engages from below with the first pair of side-edge portions, and wherein the grid of profiles engages from above with the second pair of side-edge portions. The grid of profiles engages with said first and second pair of side-edge portions such that a clamping action that counteracts lateral displacement of the ceiling tile ( 500 ) is provided. There is also provided a method for mounting the suspended ceiling. Furthermore, the present inventive concept also relates to an improved ceiling tile ( 500 ) for a suspended ceiling.
