About Aeroseal Technology

Aeroseal Duct Sealing is a patented breakthrough technology that tackles leaks from the inside out. By isolating the ducts and using computer based software, our technicians are able to accurately measure the original duct leakage and improvement achieved with the Aeroseal process in your system. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is closed.


The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it. The research was funded by US Environmental protection agency, US dept. of Energy, Electric Power Research Institute and California Institute of Energy and Environment. The University of California was granted initial patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology.
