Conducting a more detailed inspection of the building’s twenty-plus air handling units, the Aeroseal team identified seven systems where sealing would provide the highest ROI. Working over summer break, the seal team tackled each system individually, at times, dividing some of the larger duct systems into smaller sections.

The Aeroseal process used to seal the ductwork is highly effective, it eliminates the costly and highly disruptive demolition and rebuilding typically required with traditional duct sealing methods. The aerosolized sealant is blown into the duct interior, where it has easy access to the entire duct system. Once the sealant particles encounters a leak, it forms a tight bond around the hole, sealing it tight. The computerized sealing system measures the leakage rate as it seals, providing operators with an accurate account of the process.
