Insulation makes it much easier to keep your home warm in winter and cool in summer, and helps to keep your energy costs down. Ceiling insulation is particularly important as the highest proportion of heat transfer occurs through the ceiling and roof, but you can also insulate walls, floors and water pipes.
It is usually easier to install insulation—especially for floors and walls—when you're building or renovating, although it is possible to retrofit at any time.

- Review our information on insulation requirements.
- Find out if you already have any insulation in your home. If you don't know, check your building report if you have one or have an expert check your home for you.

- If you're building or renovating, talk to your builder, insulation expert or local council about minimum insulation requirements and recommendations for your area.
It is important to install insulation correctly. Before going ahead make sure you:
- Talk to different installers and suppliers about your options and get several written quotes which include specified R-values to ensure you get the right insulation for the best price.
- Check that your installer is qualified to do the job. Qualified installers will be aware of insulation safety issues and will ensure building standards are met as well as giving you the most energy efficient outcome for your home. It's always advisable to seek advice from your state or territory government or building bodies—see Resources below.
- Find the best qualified installer for your particular circumstances. Ask for personal recommendations from friends and colleagues, or check with people in the building industry you trust. You can also ask your local building industry association for a list of names if they have one.
- Seek advice from another provider if an installer cannot adequately address your queries—especially in relation to the relevant building and safety standards.
- Ask suppliers about any additional costs that may not be included in the quote such as covers to keep insulation away from down lights and other safety enclosures for electrical and fire safety.
- Arrange a time for installation. Talk to your installer about how long it will take and what preparations you may need to do like moving or covering furniture.
- Confirm that all safety checks have been completed and safety requirements have been met.
- Talk to your installer about removing rubbish responsibly.
- Enjoy your increased comfort and energy savings.
