This is good news but we are concerned that the Australian Government's focus on insulation:
1. will lead to more low quality installation of insulating materials (greatly reducing its cost effectiveness), and
2. ignores the enormous potential offered by simultaneously targeting air leakage control.
- 5% gaps in insulation reduce effectiveness by 50%
- air leakage can account for 30% of a home’s heating and cooling costs
- insulation does not stop air leakage
