You could use the stiff dryer duct you have linked to your last post. If you do, you will need clamps.
I use flexible duct that looks like it is wrapped in foil, uninsulated. I use the insulated kind outside the room to reduce noise from the fan. I utilize zip ties instead of clamps. They are much cheaper and easier too. Just dont get the ducting that is transparent, I used this at one of my penetrations into the room and found that when the lights were off the sun was shinning right through it. I ended up wrapping it with foil tape.
