The suspended ceiling further comprising paint applied to the edge sections of the ceiling plates whereby the air flow resistance through the edge sections is increased. The suspended ceiling further comprising means for forming tight connections with a high air flow resistance between either, the ceiling plates and the grid profiles, or, between two adjacent ceiling plates.
