RESULTS

Eliminated duct leakage in a 127,000 CFM system including all HVAC, exhaust and smoke extract systems

When the leakage was first discovered, walls of the two five-story building structures were already constructed around the ductwork, making the leaks seemingly impossible to access without significant demolition. Engineers had even tried lowering workers down the risers in an effort to find and manually seal the multitude of leaks, but this proved to be hazardous and ineffective.

An Internet search for a better solution led the engineering team to Aeroseal – a duct sealing technology that works from the inside to seal leaks. After the technology passed rigorous safety criteria, an Aeroseal team was brought in from the U.S. to demonstrate the technology on several leaking risers. Test results were so impressive that the building engineers decided to use Aeroseal throughout the complex, including the HVAC exhaust, the HVAC supply, the HVAC return, the lab exhaust, the kitchen exhaust, and the structure’s entire smoke extract system – a 127,000 CFM system in all. Work was completed in two weeks.
