Duct tape be used for insulation

Duct tape be used for insulation - “1001 Uses for Duct Tape - And Ducts Are Not One of Them”? Being a licensed contractor, if it is a minor repair, then “knocking” it back in MIGHT be OK. BUT, are we talking about a metal duct or a flexible duct?

Either way, DO NOT USE DUCT TAPE! You want to use Metal Tape, or Aluminium Tape. This is tape that you should be able to find at any hardware store. This is more ideal.

Why?

Duct tape has oil that the manufacturers use when making the tape, which gives it that extra adhesiveness. However, over time, when the duct system is warmed and cooled, it will dry out the duct tape, which will render the tape useless.

As contractors, we strive for energy efficiency. By sealing the duct system with a metal tape and Teflon mastic seal, we eliminate any inefficiency by way of duct leakage. Think about it this way, just 10% duct leakage can increase your energy costs almost 30%.

You said the ductwork was in the attic, so the last thing we want is any duct leakage in an attic. You do not want your air conditioning leaking into a hot attic, or vice versa during the winter.

When doing this repair, make sure that you seal up the duct with metal tape, then double check the duct after the system is turned on to test if there is any air leakage
