Aeroseal Case Study - Toronto Museum House

Improving Air Flow in Newly Built MuseumHouse Required Major Teardown and Rebuild Work - Until Aeroseal Provided a Way to Seal Duct Leaks from the Inside

 
Location:Toronto, Ontario
Type:19-story ultra-luxury condominium, 27 units
Goal:Meet air handling specifications.
Before Aeroseal:
300+ CFM of leakage.
After Aeroseal:
6.5CFM of duct leakage.
Results:
Reduced leakage by 90%.
 

The MuseumHouse is a centerpiece of luxury living located on Toronto’s prestigious Bloor Street West. At $2 million to $12 million apiece, each condo apartment offers residents a stunning panoramic view of the city, a private elevator, a grand terrace, and sparkling glass walls. Until recently, it also came with excessively leaky ductwork. In order to pass its performance audit and meet air handling specifications, owners of this newly constructed high rise had a choice: either tear down the interior drywalls and manually seal each of the building’s 25 individual duct systems, or use Aeroseal. Aeroseal was used to quickly seal the leaks and get the HVAC system working to specification. No costly renovation required.


Aeroseal works from the inside of the ductwork to seal leaks. The furniture, artwork and other valuables in the occupied apartments were first covered in plastic and filtration fans were used to catch any errant sealant particles, minimizing cleanup requirements. Then the Aeroseal sealant was sprayed throughout the inside of the ductwork. Average time required to seal an apartment from beginning to end – including cleanup: one day. Average results: 90% of leakage eliminated, reduced air loss from 300 CFM (cubic feet per minute) to 6.5 CFM. Armed with Aeroseal expertise, the HVAC contractors have become an increasingly popular group as word of their unique capabilities spreads.

Aeroseal was the only viable option there was. Our only other alternative was to tear down the walls inside each apartment and seal the individual duct systems manually. From a purely monetary standpoint, this approach saved us hundreds of thousands of dollars in renovation costs. Aeroseal works – and works very well, reducing average leakage from about 300 CFM down to around 6 CFM.

Even if we were able to access the ductwork to manually seal the leaks, the design of the building itself would have made the work impossible. The space between the duct system and the surrounding structures left no room to get sealant on all sides of each joint. The unique supply grill left little space to reach the leaks typically found there as well. By sealing from inside the ductwork, Aeroseal made us heroes. It allowed us to access all the leaks while leaving the walls and all the beautiful detailing intact.

Aeroseal saved The MuseumHouse thousands of dollars in project costs while proving minimally disruptive to its residents. It allowed the building engineers to easily get the HVAC system well under legal specifications and is about to save condo owners hundreds of dollars each year in utility costs.
