A: If a suspended ceiling system is being installed in conjunction with an Accordion Door, the use of a recessed hat channel will simplify the job. If the ceiling is already in place, the most common practice is to place a finished 1” x 6” board on the underside, or room-side, of the ceiling and another board on the topside of the ceiling. Fastened together, these will form a sandwich of sorts, with the acoustic material in between. Drop wires or rods installed from above will support the door and plates, and the track can then be attached to the underside board. It’s important to note that finished opening dimensions will be affected, so measure from the surface that the track will attach to, to the finished floor.
