Can you use duct tape on heat vents?
The adhesive used in general purpose duct tape is not built to withstand the conditions that HVAC-specific tapes are tested to perform in.

What kind of tape do you use for air ducts?
Foil-backed tape: This is the best tape for heating ducts. It uses a large amount of acrylic or butyl adhesive to resist drying out and becoming brittle. The metal foil backing also withstands temperature changes without shrinking and failing the way cloth-backed duct tape does.
Is duct work tape heat resistant?
Duct-Tape is heat resistant due to the industry standards regarding the type of adhesive it has to have. The adhesive makes it much more difficult for the tape to catch on fire or melt, and it will stop being effective much earlier than it burns.
What temperature can duct tape handle?
