The History of Aeroseal

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.


?Sealing the air duct system in a residential home typically takes only 4-8 hours.? Sealing process in commercial building depends on the leakage in the duct work and specific air flow or ventilation problem.

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.?You?ll immediately receive energy savings and a noticeable improvement in home comfort.
