We seal all types of ventilation ducts. Sheet metal, flex duct, duct board, supply and return, exhaust risers, horizontal branches, toilet exhausts.... anywhere air can go, Aeroseal can go to find and fix air leaks. Using an aerosolized sealant, Aeroseal seals ducts from the inside. And it has been proven to be up to 95% effective.
All ventilation ducts leak. It’s just a matter of how much. Even ducting installed to a very high standard will have some air loss and we can remedy this quickly and effectively. The sealing progress is live graphed as we work, so you can watch the leaks disappearing.
We can seal ducts within hours to improve a building's energy performance, balancing between zones, thermal comfort and indoor air quality. And save you money on your power bills and HVAC operating costs.
Aeroseal technology has been used in the US for over 20 years [read US case studies] and is successful in Europe [read European case studies] and Australia.
