Aeroseal Technology

The Power of Aeroseal

Homeowners and commercial businesses looking to have their ducts properly sealed often do not know how the different methods compare. Traditional sealant technologies, such as tape and mastic adhesive, may help cover up obvious damages but tend to be ineffective against leaks that are hidden behind walls or other hard to reach places. That is why our duct sealing team chooses to use Aeroseal, the most cost-effective solution to fixing leaky ducts.

How it Works

Aeroseal technology is a fast, safe, and effective way to seal duct leaks. Invented and developed at Lawrence Berkeley National Laboratory in 1994, Aeroseal internally seals leaks by injecting aerosolized vinyl polymer sealant particles into a pressurized duct system. The ductwork is pressurized using a calibrated-flow fan, which keeps the aerosol moving through the ducts without collecting on the surface; the particles remain suspended in the air flow until the change in pressure around leaks and holes forces the aerosol adhesive through the cracks, where it collects on the edge and builds a seal to effectively block air flow.

Many benefits come with using Aeroseal technology; aside from lower energy bills, Aeroseal works to eliminate excessive humidity and dust, car exhaust, musty odors, and other harmful fumes that circulate through the home. Aeroseal helps to make you considerably more comfortable by delivering air more efficiently, consistently, quicker, and evenly. The savings you get from aerosealing your home pay for itself in three to five years in perfect conditions, and is much more effective than installing new windows or insulating walls. When the average American household spends $2000 in energy bills, you can’t afford to lose any of it to duct leakage. Using Aeroseal technology, Duct Diagnostics can help keep your ducts healthy at a price you can afford.
