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 started to be used commercially in January of 1997.

The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory. The University of California was granted patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology. 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.

In 2012 the Aeroseal technology finally arrived in Canada. Worldwide over 100,000 homes and buildings have been sealed using this technology and this number grows every day.
