They sell foil covered fiberglass insulation in rolls just for that
use. You DO NOT want to use anything that is not made for this
purpose as a fire could start, at least nearest the furnace. You
apply this stuff with a special aluminum duct tape.
To make for easy cleaning, leave a few gaps where you open the ducts.
Maybe cover them with something easy to remove. A piece of this same
insul. held in place with steel wire would be one way.
