Abstract: A ceiling system which includes a plurality of grid elements which form a grid framework and a plurality of downwardly accessible ceiling panels. The ceiling panels include a substrate and at least two mounting members. Each mounting member cooperates with the substrate to provide strength and rigidity characteristics to the substrate and to form a grid receiving cavity. Each mounting member further cooperates with a grid element to accurately position the panel relative to the grid framework. When installed, the system provides no visual indications on how the ceiling panel can be removed.
