thin duct?

I was wondering if there is such a thing as a thin duct? I am hoping to finnish my basement that has a low ceiling and the issue is that there is a full size duct running the length of the room thus causing the occasional head bump but more importantly I would like to close the exposed ceiling with drywall. Can anyone help me on suggestions?

There are insulated flexible ducts available and may be an option. Check with local building inspector re: codes and permits. Codes vary from area to area. I believe there are codes re: finished ceiling height in basements and changes in ductwork.

Stop and think about it. Yes some time we go down to a 6" deep duct in the basement. But you have to keep the same sq " in this new duct.Then they get so wide that the metal goes bang a lot when the blower comes on. Like said is there a code there . Have ran 5/8 drywall tight to it. If span is not to big. Best is a drop ceiling that takes about 3/4" under the duct.
