Ductwork insulation application?

I am preparing to add insulation to my hot air/air-conditioning and would like to know if the aluminum face attaches to the ductwork or whether it is installed with the aluminum on the outside?
Thank you

Flexible or rigid ? What does the manufacturer say?

Seal the ducts completely first. Then the aluminum foil goes on the outside, taped with foil tape.
