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

The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it.

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

The Aeroseal sealant has been in use for over eighteen years. It is a vinyl material that is suspended in a water solution. Once atomized, the sealant is air dried and is deposited principally at the leaks without coating the inside of the ducts.

In 2000, The Department of Energy and its Citizen Judges selected the 100 best scientific and technological accomplishments to come out of the 23 years of DOE's existence. The citizen judges narrowed down the field to the 23 technologies that have the largest potential to save consumers money and improve their quality of life.

Aeroseal's duct sealing technology was selected to receive both awards.
