University Hospital Uses Aeroseal for Safe, Unobtrusive SealingBilly Pell
UOHI turned to new duct sealing technology to solve one problem and wound up solving two.
Hospital monitors detected that an isotope created in one of the institute’s laboratories had
somehow migrated to an adjacent wing of the building. By using aeroseal technology to seal
possible leaks in one of the ventilation shafts, the hospital could ensure that the isotope wasn’t
spreading from one shaft to the other. Once the shaft was aerosealed, the hospital immediately
noticed another significant benefit – dramatically improved ventilation efficiency and lower
There was only one way to ensure the migrating isotope wasn’t being spread through
leaks in the ventilation system – and that was to seal those leaks. Using traditional duct
sealing methods would have been extremely disruptive and expensive. Entire wings
would have had to been shut down as workers tore down walls to access the ductwork.
Fortunately, the hospital’s duct specialists, AWS Remediation Technologies, had heard
about Aeroseal, a breakthrough technology that works from inside the duct system. With
Aeroseal, the actual sealing process took less than a day. Regular hospital operations
“Luckily, Aeroseal offered a safe and unobtrusive way to seal the entire ventilation shaft – without disrupting regular hospital operations.”

With the vents sealed, UOHI’s engineers were able to locate the problem – laboratory
equipment leakage. They also discovered an unintended benefit of the duct sealing. The
institute’s ventilation system – which was previously running at full capacity – could be
turned down while maintaining better ventilation. Air quality was improved. Energy
usage was reduced. The hospital is now planning to use Aeroseal on other ductwork
throughout the institute. Download a PDF of this case.
