Innovative Approach To Duct Sealing Takes Home Gold Medal In Ventilation Category

There is finally a viable solution to poor ventilation plaguing most U.S. buildings today.

Aeroseal duct sealing technology won top honors in the “ventilation” category of the 2016 AHR Expo Innovation Awards competition. The technology was singled out as the gold medal winner by a panel of industry experts who evaluated dozens of entries based upon their application, innovation, value and market impact. Aeroseal will be presented with the first place award at a special ceremony to be held Tuesday, January 26th at the 2016 AHR Expo in Orlando, Florida.

“Winning a gold medal in the ventilation category is a significant and noteworthy honor,” said Neal Walsh, senior vice president, Aeroseal strategy and commercial sales. “It recognizes the fact that there is finally a viable solution to poor ventilation issues that plague most buildings in the U.S. today. Aeroseal’s unique approach to duct sealing makes it possible, for the first time, to easily find and seal leaks throughout the entire ventilation system of a building – without having to tear into existing structures.”

Aeroseal technology works from the inside of the ducts to seal ventilation shafts. Applied as an aerosol mist that is blown into the interior of the shaft, the sealant does not coat the inside surface, but instead, accumulates primarily in and around holes and gaps in the shaft, bonding to other sealant particles until the leaks are completely sealed. By finding and sealing leaks from the inside of the ductwork, the aeroseal technology can quickly and easily locate and seal even the most inaccessible leaks without having to demolish walls, rip open ceilings or disrupt existing structures – a requirement of other duct sealing methods that have, for decades, made ventilation repair unfeasible in many cases.

Aeroseal technology has been used to repair ventilation shafts in hundreds of building around the globe – from skyscrapers in Dubai to hospitals and medical laboratories in New York, Boston and San Francisco.

“It’s estimated that around 80% of existing buildings in the U.S. today have ventilation shafts that leak 20% to 40% or more,” said Mark Modera, professor at the University of California, Davis and inventor of aeroseal technology. “This is having a significant impact on energy usage and can lead to a variety of indoor comfort and health-related indoor air quality concerns. While building engineers have been well aware of the problem for decades, there has been no practical solution – until now.”

The Innovation Awards competition is jointly sponsored by the AHR Expo, ASHRAE and AHRI. For more information, or to request an invitation to the award ceremony, contact Aeroseal at (937) 428-9300. To learn more about aeroseal technology, visit
