Aeroseal® Duct Sealing Technology
The Aeroseal® advanced sealing method for HVAC ducting, seals from the inside. The process has minimal disruption to the occupied space, avoids system reconfiguration whilst delivering cost savings on energy bills, improved comfort, enhanced Indoor Air Quality and increased HVAC performance

Early Australian adopters including Design Consultants, EEC and commissioning consultants advocate for this test and seal service because it works. Using Aeroseal in Australian conditions is the cost effective solution to optimising Building HVAC Energy Efficiency and Comfort. Aeroseal ROI dramatically improves BMS performance. Measurements taken in pre-sealing tests in Australian buildings shows that duct leakage averages from 15% to 40%. AS4254.2 2012 states that rigid ductwork should not leak more than 5% at an airflow of 3000l/s and above. We will continue to lead this “tight building” specialty practice and technology.

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.


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.
