Ceiling Tile with Integrated Baffle

Ceiling tiles for drop ceilings are disclosed. The ceiling tiles have a main portion that is sized and adapted to fit within a grid of the drop ceiling, and a baffle that hangs down from the main portion. The ceiling tiles may be arranged such that they can be made, shipped, and sold in a flat configuration and folded into a three-dimensional configuration with the down-hanging baffle for installation. For example, a sheet of tile material may have a plurality of fold lines defined in it that allow the sheet to fold in such a way as to define the main portion and the baffle. In the flat configuration, the sheet of tile material may have the dimensions of a standard drop ceiling tile; in the folded configuration, the ceiling tiles may also have standard ceiling-tile dimensions. A single ceiling tile may have two or more baffles, and those baffles may be staggered in position with respect to one another.
