“Testing showed after installation, the new ductwork wasn’t even close to meeting New York’s building standards for leakage. The engineers were looking at the real possibility of having to shut down operations at the hospital while they tore into existing walls in order to access and seal the ductwork. Then someone told them about a duct sealing technology that worked from the inside of the ductwork to seal leaks. Aeroseal was absolutely a project saver.” —Jim O’Keefe, Project Manager TechClean Industries Ltd.

Aeroseal Benefits:

  • Reduces up to 90% duct leakage
  • Fixes pressurization issues
  • Decreases fan horsepower
  • Extends equipment life
  • Better IEQ
  • Increases comfort
  • Does not require shutdown or interruption of daily operations to Aeroseal buildings
  • Consumes less energy
  • Saves on heating and cooling costs


Proven Positive Outcomes in Clinical Spaces

A typical hospitals loses 25-40% of heating and cooling energy throughout the ductwork. Aeroseal reduces up to 90% of duct leakage. Our commercial duct sealing system will reduce heating and cooling costs by up to 20%.

Our duct sealing solution covers:

  • Medical clean rooms, central sterile supply and medicine storage areas
  • Patient care areas, hospital rooms, isolation rooms, surgical suites, emergency rooms, waiting rooms, and ambulatory care
  • Professional ancillary areas, laboratories, radiology, and pharmacy
  • Support, operations, data center and mechanical rooms

Case Study

Memorial Sloan Kettering Cancer Center Aeroseal Reduces Ventilation Leakage

Aeroseal Technicians: TechClean Industries Ltd.

Goal: Reduce duct leakage, meet construction guidelines, and reduce energy waste. Duct leakage before Aeroseal: 8,729 CFM (average)

Duct leakage after Aeroseal: 613 CFM (average)                                                    Results: Leakage reduced on average by more than 93%.

“The new construction work led to significant duct leakage that we knew had to be addressed from both a building guideline and energy savings perspective. The aerosol duct sealing process allowed us to seal more than 90% of the leaks with little if any disruption to the day-to-day functioning of the facilities.” —Hospital Administrator, Memorial Sloan Kettering
