Abstract (en)

[origin: WO2019150024A1] The invention relates to a flexible layer (2) intended for the production of a suspended ceiling in a room, said layer (2) being made up of two sheets (3, 4) stacked and assembled together at the peripheral edge thereof, one of the sheets (3, 4) being solid, the other being perforated. The sheet arranged on the top, which is perforated, has a higher grammage than the solid sheet (4) arranged on the bottom, so that the perforated sheet (3) is kept attached to the solid sheet (4) when the layer (2) is fastened to the stringer.
