CASE STUDY
Cox Science Building
TYPE: Education
The University of Miami’s Cox science building was undergoing a partial renovation. After testing dozens of fume hoods located in laboratories throughout the four-story building, the school’s environmental health and safety group found many of the hoods were not providing sufficient exhaust. The reason: leaks in the connecting ducts and ventilation shafts.
Traditional duct sealing methods would have required a near demolition of the 50-year-old building. Instead, the duct sealing crew at AirMax Service Corporation used Aeroseal duct sealing to successfully seal all nine targeted duct systems in less than two weeks. No demolition. No interruptions. 100% code compliance.
“Research showed Aeroseal has been successfully used at a number of other universities, science laboratories, and hospitals. It was great to watch the computer monitor as it tracked the sealing process. You can actually see the graph go down as the leaks are being filled. We were pleased with the results and I wouldn’t hesitate to recommend it to others.”

We could have completely demolished and replaced the existing duct system… or used Aeroseal. The choice was a no-brainer. In the end, Aeroseal proved to be a highly effective – and cost-effective – means of sealing the leaks and getting the fume hoods under safety compliance.
The complex intertwining of internal duct systems and surrounding construction made locating and accessing leaks specific to targeted hoods impossible for traditional duct sealing methods. Short of demolition and rebuilding, the only viable option was an Aeroseal duct sealing. This system, proven safe and effective, uses a mist of aerosolized sealant to find and seals leaks from the inside of the pressurized ductwork.
The 20 fume hoods were connected to rooftop exhaust fans via nine separate duct and ventilation shaft systems. One at a time, each duct system was blocked on both ends so that incoming air could only escape through leaks in the duct walls. The Aeroseal system was attached to each shaft until the leaks were completely sealed. A retesting by a third party TAB company confirmed what Aeroseal indicated: all nine shafts were properly and effectively sealed.
