What Is Aeroseal Duct Sealing?

The ductwork in a ventilation system must retain an airtight seal along its length or else it will cause a drop in air pressure from the heater and air conditioner. If your home experiences a decline in comfort due to low airflow from the vents, or if you notice a rise in heating and cooling costs for which you cannot account, the culprit may be a loss of integrity in the ductwork. Fixing leaking and damaged ducts requires indoor air quality specialists armed with the best technology—such as Aeroseal Sealant.

How the Aeroseal Process Works to Repair Your Ducts

The Aeroseal process is different from most standard duct sealing methods, such as using mastic sealant or metallic tapes. Where other techniques approach the ducts from the outside, applying the sealant to the holes, Aeroseal uses an approach from the inside. This process is faster, more thorough, and can reach difficult to access ducts such as those in the attic or underneath flat roofs.

What happens during the Aeroseal process is that polymer particles are released into the ventilation system after the air inside the ducts is pressurized. The pressurized air escapes through any available opening, and the polymer particles are drawn toward these holes, where they adhere to them and build up until the leak is completely sealed. To make sure the process works, a computer monitors the internal pressure of the ducts until it detects that the leakage had been sealed. This will eliminate all leaks, including many you may not have known about.

Although Aeroseal is an efficient and effective method for duct sealing, not all ductwork or types of damage will benefit from it. The process works best for smaller leaks. If you have more extensive damage in your ventilation system, technicians will use hand-sealing with mastic or metallic tapes to take care of the problem. As long as you rely on experienced indoor air quality professionals for the work, you can rest assured that your ducts will receive the type of sealing they need.
