About

The patented Aeroseal sealing process is the most effective, affordable and viable method of sealing the
central heating & cooling and ventilation ductwork in residential homes and commercial buildings.

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.

The Aeroseal duct sealing system effectively seals the leaky ductwork from the inside by using a UL
tested and approved sealing material. It’s clean, safe, and guaranteed for 10 years in residential
application.

Sealing the air duct system in a residential home typically takes only 4-8 hours. You’ll immediately
receive energy savings and a noticeable improvement in home comfort. Sealing process in commercial
building depends on the leakage in the duct work and specific air flow or ventilation problem.

The Aeroseal process won the “Best of What’s New” award from Popular Science magazine, and the
“Energy 100″ award from the U.S. Department of Energy (DOE). The DOE also rated the Aeroseal duct
sealing process as one of the 23 most beneficial technologies available to American consumers that has
come out since the agency was created.
