AEROSEAL® INDUSTRY-LEADING DUCT & AIR SEALING TECHNOLOGY
Improving the lives of Australians by delivering comfort, healthy air, and substantial energy savings.
Aeroseal® Duct Sealing
Reduce Energy Consumption
The Department of Energy ranks duct sealing as one of the most effective ways to reduce energy costs.
Improve Indoor Air Quality
Leaky ductwork is a key contributor to poor indoor air quality, directly impacting the health and well being of a building’s occupants.
Optimise Building Ventilation
Ventilation issues can be serious. They waste energy, cost money, and greatly reduce indoor air quality.
Pass Code Compliance
Building and energy codes change frequently, but with Aeroseal projects they pass inspection — every time.
Aeroseal® Seals Leaks
From the Inside
The patented Aeroseal® technology allow us to pressurise the duct system with an aerosolised Vinyl Acetate Polymer which finds the leaks due to pressure differential between inside and outside. It then seals any holes up to 15 mm. On completion we supply a Test Certificate which shows the Pre-Seal and Post-Seal Leakage rates.

Aeroseal® duct sealing were able to reduce the leakages to around less than 95%
Why should ducts in commercial buildings be sealed?
Duct sealing in commercial buildings cost-effectively saves energy, improves air balance and thermal distribution (comfort and ventilation), helps comply with building codes and reduces cross contamination between different zones in the building (i.e., smoking vs. non-smoking, bio-aerosols, localised indoor air pollutants).
How much energy does the sealing process save?
Energy savings are different for light commercial vs. large commercial buildings and obviously depend upon the initial duct leakage level. The Aeroseal Energy Savings Excel spreadsheet can be used to estimate the savings for both types of buildings. For ducts above an insulated ceiling in a light commercial building, energy savings should be 10–30% of HVAC energy use, and peak electricity-demand reduction is generally a higher percentage. In a large commercial office building with a VAV system, energy savings and demand reduction should be 20–40% of fan-system energy use and 5–10% of cooling energy use. As a rough estimate, excluding any of the non-energy benefits of duct sealing, simple payback times typically range from 1 to 4 years, and return on investment between 30% and 70%.
How do I know if the ducts in my building need to be sealed?
The existence of duct leaks in your building can be uncovered several ways. One way is to examine Test and Balance reports, comparing the total flow through the grilles with the total flow through the air handler, or by looking for systematically low flows at grilles that are far from the fan. Another way is to test a sample of duct sections for leakage, a test that Aeroseal technicians perform on a regular basis.
