I've heard people mention using aluminum tape instead of duck tape on
exhaust vents. Trouble is, does it really make a difference over duck tape.
I notice that duck tape doesn't do squat for exhaust vents - it just
wrinkles up and shrivels away.
Also, what does this stuff look like and is it available from the Borgs?
Last time I looked, somewhat half-assed, I only saw duck tape.
Is it actual tape, or something that I'll have to carefully clean the vent
before using and then apply an epoxy to cure it? (yes I'm being hyperbolic
but just to make a point)?
One of the nice things about duck tape is that you can practically apply it
underwater and it will stick just fine.
If it's really exhaust vents you're doing, there's some high temp stuff
(a bit harder to find) you should use. I didn't read carefully the
first time. All this stuff has a range of temperatures to which it's

There are a zillion kinds with a zillion certifications. Covalence
Adhesives makes the popular Polyken, Nashua and others.
I'm not one to push Wally World but if you want some really sticky-ass
foil tape, they have it. I doubt it is certified for anything except for
sale at WM.
That might be why they recommend something else.
Duck tape was never meant for ducts, aiui. I'm not even sure it was
named after ducts. Maybe ducks. Sort of like Gorilla Glue.
I'm sure they have more at the Borg than duck tape. Unless you went
to Just Duck Tape, or Duck Tape 'R' Us.
I don't know what point you are making. If it is dirty enough,
nothing will stick. If it is only a little dirty, everything will
stick. Everything else falls somewhere in between. What are you
going to do, use something that doesn't work, that shrivels up, just
because it sticks well at first? I would dust the places about to be
taped, and then I would tape the worst one or two joints and see how
well it sticks over the next month or two. If it doesn't stick, I'd
clean the others before I taped them. But I have a feeling you're
just trying to goof on us with your reference to steel wool and
alcohol. I think things will go better here if you show you are
trying to be funny instead of just putting us on.
I wonder about posts like these. It sounds legit, but then there's an
aspect that is so boneheaded as to raise suspicion. If indeed the
poster is wondering about stickiness, then we should advise him to
properly prep the area first.
Aside from that, aluminum tape is the correct stuff for ductwork that
requires insulation. Good old duct (not duck) tape is the correct
stuff for ductwork that does not require insulation. You can use
aluminum tape in place of duct tape, but not the other way around.
Duct tape is ok for temporary uses but for long term use you need the
real thing. You will usually find it in the heating and air conditioning
section, not with the regular tape. It will be more expensive and you will
need to peal off a layer off the adhesive as you use it.
As noted if you are working with the vent from a fuel burning heating
device (not like a dryer or furnace duct), you may need a different
Naw, its just for the furnace exhaust and the hot water heater exhaust
Just out of curiosity, what kind of device would be burning too hot for
aluminum tape? Fireplace insert or something similar?
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
It is not the aluminum that is a problem, but the adhesive that will be
damaged and fail.
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
