SUSPENSION CEILING SYSTEM COMBINING SNAP-UP PANS AND LAY-IN PANELS ABSTRACT OF THE DISCLOSURE A suspension ceiling system is disclosed which combines snap-up pans and lay-in panels. Such system includes runners formed with channels at the lower edges thereof formed by opposed lateral flanges, depending side walls, and inturned lips. The inturned lips terminate at inner edges which are spaced apart to provide a longi- tudinal opening on the lower side of the channel. Lay-in panels are positioned in some of the grid openings, and provide peripheral edges supported by the flanges. Snap-up panels formed of sheet metal are provided with peripheral flanges having inwardly directed ribs extend- ing lengthwise of the flanges and spaced from the lower pan surface. The flanges are positioned in the openings between the runner lips with the ribs snapped over the associated lip to secure the snap-up panels in position. The lips provide a delineation between the lay-in panels and the adjacent flanges of adjacent snap-up panels are spaced by substantially the same distance to provide a similar delineation. When sound absorption is required, A snap-up pan is installed in the same opening as a lay- in panel to define a chamber therebetween. Such snap-up pan is provided with apertures open to such chamber.
