Abstract: A panel assembly includes a resiliently deflectable panel and a plurality of retainer clips. The panel includes a relatively thick rectangular base section and a relatively thin rectangular lip section which extends outwardly from the periphery of the base section.

Each panel is placed in its desired mounted position with its mounting edge member in contact with the adjacent gasket so that the edge of the sheet is spaced to the side of the central rib which ends between the sheet outer surface and the support member. Resilient clips are engaged at intervals along each sheet between the sheet's recess and the corresponding shoulder to pull the sheet into sealing contact with its gasket via its mounting edge member.

Abstract: A suspended ceiling system having tiles and fixtures with interspersed hooks resting on runners. The hooks from adjacent ceiling components rest on the top of the same runners, but not upon each other.

When used on the opposite side for a neighboring tile, the hooks from either tile land in the space between the hooks on the other tile. Although resting on top of the same runner, they do not lie on top of each other, permitting the removal of one tile without disturbing any others.
