The issue is confusing, because it wasn't used for ducts until long after it
was invented.

Not so confusing now, as apparently there's a manufacturer of the stuff
with "Duck" in its name, putting out a product called
"'Duck Tape' brand of duct tape." Obviously in their interest to have

And what is worse is that the stuff commonly called "duct tape" - fabric

ducts but the common "duct" tape is not one of them.

I am surprised that no one has mentioned gaffers tape.

Duck tape and duct tape are TWO DIFFERENT THINGS!!!!

Duck tape is made from cloth and is a REALLY bad choice for using on ducts.
It was designed originally to repair tarps and withstand the weather.

Duct tape is made from metal foil and is designed for use on metal ductwork.

Wrong. Again.

The original DUCT tape had and still has NO metal foil.

Metal tape with adhesive is known as "flashing tape", used to seal the

roofing material or between walls that are built hard up against each other.
Flashing used to be done with lead foil sealed/glued with pitch, now it
is done with adhesive metal [usually aluminium] tape, hence "flashing tape".

I never came across using aluminum foil tape as flashing. I have used
it for ducts, for hot exaust pipes, and other uses. Flexible sticky flashing
is now usually done with mineral based sheeting with polyethelene
backing. Most auto parts stores sell metal tape. I used some stainless
tape for covering chrome or chrome like parts. I just recently came across
the cloth tape with mild stick, or gaffers tape. New to me. There are
different backings for duck tape. I like using the remants of the not
available anymore, 100 MPH tape from Sprotsman Guide, orginally used
to repair aircraft wings. It has a stretch unlike most, and really
holds up and sticks well.

The 'gaffer' is the charge hand electrician on a film etc crew. And only
really one per unit. With a large crew on a big rig he is more likely to
delegate the jobs needed to be done than do them himself - like any good
crew chief. Organise the work among his crew to prevent two doing the same
job - or the lazy ones doing nothing.
Perhaps the primary use of gaffer tape these days is fixing filters to
window frames etc. But I dunno if that was the original intended use -
although old I'm not *that* old. ;-)
But the same tape is equally used by other crafts within the trade - even
although others also have their own tape, like camera tape, fairly
similar to gaffer in construction in that it's fabric reinforced but 1"
wide and white and originally used to seal film tins.

I wonder on what sort of construction?

In the UK where buildings pretty well all have stone walls, the lead
flashing is bent into a 'chase' created in the masonry, usually the mortar
between coarses, secured with lead wedges and mortar applied afterwards to
seal. A lime based mortar is best to accommodate some movement. Down the
edge of a roof where it meets the brickwork it will be cut into a step
shape to follow the line of the horizontal bricks. And it's still very
much in use today - despite the cost.

An aluminum metal tape is also used to seal the seams between the
metal-backed foam insulation on homes. The adhesive is permanent, and
the tape is pretty expensive as such things go, but it keeps out the
wind (and water) well.

Ironically, NOT for ducts. I suspect some fly-by-night heating and air

According to :

It is simply because the crap they sell at Wal-Mart is not GI grade
(AKA 100 MPH duct tape). I had some I used on dive gear that held up
for many years and regularly used under water.
You can still buy it at some military type stores but it costs over
$10 a roll.

While perhaps not _quite_ Mil-Spec, you can get a very close equivalent
at other places. Lee Valley carries it for example.

Because just like a lot of stuff there is a quality version and a cheepo
version designed to be sold in big box stores.

If you go to a real supply house you can buy quality duct tape.

I'm not sure who you were asking, but the tape does not and can not be what

If ducts are made properly, they should be locked together by a folded
seam by which the ends of the ducts slide together and an edge is then
folded over to lock it all together.
Look up "pittsburgh seam" or "pittsburgh seaming" and "ducting" on Google.

duct tape was originally developed during World War II in 1942 as a
waterproof sealing tape for ammunition cases
then why does it fail so rapidly when exposed to water or high humidity?

just curious,

The biggest failure is drying out.

Where in world did you come up with duck?? One doesn't tape ducks; one
tapes ducts. except it isn't very good for that.....

Some american hardware stores stock duct tape with the trade name
Duck.
