Insulate your ceiling, walls and floors

Approvals Needed Owners Corporation iconLandlord icon


Insulation is generally the single most effective investment that can be made to improve a home’s energy efficiency. It acts as a barrier to heat loss and heat gain, particularly in roofs and ceilings, walls and floors.

It’s really only an option if you live in a top floor unit with a cavity between your ceiling and the roof.

The Australian Government’s Your Energy Savings site has comprehensive information on insulation that covers:

  • Insulation standards & requirements
  • Types of insulation
  • R-values
  • Safety with insulation

The cavity space above your ceiling is most likely to be common property (check your strata plan to make sure). You’ll need a resolution of the owners corporation at a general meeting. The owners corporation will also require a by-law to ensure you’re responsible for ongoing maintenance.
