Aeroseal’s History

Aeroseal’s patented technology seals cracks and holes in new and existing air duct systems. Dr. Mark Modera, a scientist at the University of California, invented the technology in 1994. Aeroseal began doing business in January, 1997.

The technology was developed and tested by Indoor Air Quality scientists at the Indoor Environment Program at Lawrence Berkeley National Laboratory.

The University of California was granted patents in 1996 and 1999.  Aeroseal holds an exclusive license to this technology.

Aeroseal sealing research and development was funded by the:

The Aeroseal sealant has used for more than 18 years. This vinyl material is suspended in a water solution that, once atomized, is air dried and deposited principally at air duct leaks — without coating the inside of the ducts.

In 2000, The Department of Energy and its panel of citizen judges selected the 100 best scientific and technological accomplishments to be developed during out of the 23 years of the agency’s existence. The panel narrowed the field to the 23 technologies that have the largest potential to save American consumers money and improve their quality of life.

Aeroseal’s duct sealing technology was included in both award categories.
