Hi,
Is there something like temperature stable putty I can use instead of
duct tape to seal small air leaks on the duct? (screw holds, joints, etc.)

Aluminum tape is better

And I have to ask...is it a Canadian duck or Mallard?

Hi,
I used Al tape. But for some cases tape is not much help.
Mallard is more colorful. Lots of water fowls in front of my house.
Bow river flows past my house. One of the best trout fishing ater.

There is a product called Thumb Gum....but really don't recommend for
ductwork. The AL tape is nothing like the Duct Tape. Duct tape is a fiber
material and the Al tape is thin metal substance...very sticky

Use duct mastic "DP1010". But it is approved for use on metal only, not
flexible ducting. Around the plenum areas' you'll find start collars that
leak tremendously more than some minor joint connections. Try locating this
area, and sealing with duct mastic. Comes in a one gallon container and you
can paint it on using a paint brush. Keep in mind the material is thick
from the factory. Do not thin with water.

Aluminum tape is approved for use on duct board and such. UL181 approved
tape is a better choice for flexible ducting. Come 120 yards to a roll. Do
not use rubber backed duct tape without using mechanical bands. Home depot
I believe does not sell UL181 tape. They sell a product they "call duct
tape."
