Aeroseal offers a proven duct sealing technology that tests and seals air ducts from the inside. The technology was developed at Lawrence Berkeley National Laboratory in 1994 with funding from the U.S. Department of Energy, the EPA and others. Their computer-controlled process internally seals leaks in air distribution and ventilation ductwork by injecting a fog of aerosolized sealant particles.
"The [Aeroseal] technology worked. If you have an existing mechanical [HVAC] system that is ten or twenty years old, you can make it like new again – give it new life – by using Aeroseal technology…We are planning to convert a number of buildings into doctor suites and I can see Aeroseal technology being a viable solution when it comes time to rehabilitate the existing ductwork. In new construction, it can be used to seal the entire air duct system once it’s been installed."
