ABSTRACT:
A suspended grid subceiling and panel units therefor having the appearance of a continuous expanse of decorative light-transmitting block masonry. In a preferred embodiment, the panels units are assemblies of an opaque subgrid of rails and cross rails and translucent subpanels simulating the mortar lines and faces of glass block. The undersides of the grid main runners and cross runners are similar in shape to the subgrid rails and cross rails and have a surface finish matching the color and texture of the subgrid undersides.
