aluminum tape

I think it's the adhesive that isn't rated for high temps.

It amazes me that people seek folkloric explanations instead of the obvious. It also amazes me that there are people willing to explain things they don't know. Luckily we have writers willing to obfuscate instead of clarify and use words like elision. {

Traditional "Duct" tape is not approved for ducts in my understanding..

I was referring to those kind of exhaust. When I wrote furnace duct I was referring to the warm air delivery ducts that bring the heated air to the rooms. The Dryer duct is a little different as it does include the exhaust, but it is mixed with a lot of excess room air so it is far cooler than a typical furnace exhaust.

You do need the even more expensive tape for a furnace or water heater exhaust.

It is not the aluminum that is a problem, but the adhesive that will be damaged and fail.

Bingo! Ironically, sacks for picking cotton were made from cotton ducking.

Damn, well I guess I'll go do some more research then.

It seems to me that high temperature vents from gas appliances should be secure and air tight enough to not need any taping. There are codes for these things and I don't think taping is a permissible method of securing or stopping leaks.
