Duct cleaners use it to block off vents during the cleaning procedure. Duct sealing contractors use it to seal registers while doing pressurized duct sealing and diagnostics such asAeroseal.

Installers use it to temporaily block contaminants from getting into new ducting during construction. Some folks even use it as a temporary floor covering on stairs and new carpeting.
