The Duct Tape Story

Disconnected crawlspace and attic heating and cooling ducts are a common observation for The House Whisperer inspectors.

Why is this?

Could it be that standard gray duct tape was used?

It does says ‘Duct Tape’ on the tape roll… it must be the right tape for heating ducts…Right?

Wrong! During World War II, before it was called duct tape, the U.S. military bought a cloth-backed, rubber-adhesive tape for making emergency repairs on the battlefield.

Sometime after the war, heating and cooling contractors begin to use the tape to seal the joints in heating, ventilation, and air conditioning (HVAC) ducts. This tape was manufactured in the same way, though to match the metal ducts, it was colored grey rather than the green color of the Army version... and because of this use, it became known informally as 'duct tape'.

The problem is that the standard grey duct tape does not adequately seal duct joints and has a short lifespan. Hot air flowing through heating ducts and hot attics can soften the tape adhesive. Eventually, the tape slowly unravels itself… causing heating and cooling duct connections to separate or have air leaks.
