At 1,365 metres above sea level, Thredbo is Australia’s highest ski resort village — attracting thousands of winter visitors every day. In peak season, hospitality venues here need to perform at their best to keep guests comfortable after a long day on the slopes.
Our team recently completed an Aeroseal duct sealing project on an exhaust riser. The challenge? Working in cold conditions, we adapted our approach to maintain the right environment for a smooth, effective seal.
The results:
🔴 Before: 2.6 L/s leakage (4.0% of system capacity)
🟢 After: 1.1 L/s leakage (1.7% of system capacity)
📉 Reduction: 58% duct leakage reduction – well below our 3% target
That’s like shrinking an opening from the size of a snowball to smaller than a snowflake — all without dismantling any ductwork or interrupting operations.
Better sealing means better ventilation, improved comfort, and reduced energy waste — even in the snow-covered heart of the Snowy Mountains. ❄️
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.
