If you have the ceiling height, consider installing a new ceiling frame-work. Attach the center areas of the ceilign frame-work, to the actual ceiling joists, for proper support.
Install sheetrock to that. You could use wood, you could use steel for the process...again, if
you have the ceiling height.
Example: This is a room that had the existing tiled (acoustic ceiling) removed, the new ceiling was then framed, and new sheetrock installed -(with new recessed lighting and horse-hair plaster walls overlaid with new 3/8" S/R) - (rental property)
