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.
"Aeroseal worked perfectly. All the shafts were quickly sealed to levels well within the code requirements. It was a real project saver and I would definitely use Aeroseal again."
