The 17 Things

Insulation can significantly reduce the amount of energy needed to maintain a comfortable temperature inside a home. It is most often installed under roofs, above ceilings, in wall cavities and below suspended floors.

No 6: Insulation

The 17 Things

What Is It?

Insulation is the material installed in a home to control heat entering or leaving the building. It creates a barrier to the transfer of heat that is calculated as an R-value. Insulation is often installed under roofs, above ceilings, in wall cavities and below suspended floors. The most fundamental of these is ceiling insulation.

How will it help me reduce my running costs and increase my comfort?

Installing insulation is the simplest way to improve home comfort and reduce household heating and cooling bills. It substantially improves comfort levels inside homes particularly when the weather outside is extreme. Some insulation materials also reduce levels of unwanted noise adding more peace and comfort to indoor living spaces.

Insulation can significantly reduce the amount of energy needed to maintain a comfortable temperature inside a home. Using less energy means lower energy bills and improved home comfort levels.

There are two main categories of insulation – bulk and reflective.

Reflective insulation reflects heat back to where it has come and needs to be installed correctly to be effective. Bulk insulation resists the transfer of heat from one side to the other, relying on air pockets trapped within the insulation. Having both of these features in the roof and ceiling space will significantly reduce the amount of energy needed to maintain a consistent temperature inside a home. Using less energy means lower energy bills and improved home comfort levels.

What professional should I talk to about this?

The Centre for Liveability Real Estate always recommends you consult further with any relevant specialist design or building consultants or assessors before making any decision regarding your specific property based on the Liveability Property Marketing Features™.

Most architects, building designers and builders will understand how insulation works and how it can be added to your home during the planning stage. They include HIA GreenSmart builders and designersMaster Builders Green Living buildersBDA and BDAV (VIC only) building designers.

Supply and fit contractors

Many people prefer to have a professional installer supply and install insulation in their home. Contact an installer who can demonstrate an established history of installing and ensure the contracting company is prepared to offer long term warranties on performance of the insulation and on the installation of the product. Established installation contractors can be found in the Yellow Pages. Established insulation manufacturers will also recommend experienced installation contractors.

Insulation can also be easily installed in the ceiling and under the floor once the home is built as a do-it-yourself project or through a professional installer.

Do-it-yourself

There are many home hardware outlets that stock insulation products. Installation instructions are given on the packaging and added information and video clips are available from most reputable suppliers.

Ask your local supplier about which type of insulation is best suited for your needs (bulk, reflective or a combination).

Is there anything I need to know before I meet with them?

Do-it-yourself

If you’re planning to install the insulation yourself, you’ll need to find a hardware outlet that stocks insulation. To purchase insulation you will need to:

  • Know the measurements of the area to be insulated.
  • Be aware of the timber spacing between which the insulation is to be installed.
  • Decide on the performance level (R-value) to be installed.

What is the price range I can expect?

You should check if the insulation you want to purchase and install is eligible for a government rebate or incentives from your retailer. Check out our list of Current Energy Rebates.

Prices will vary depending on the size of the area to be insulated and the R-value of the product purchased. The below prices are approximate for purchasing R3.5 batts for 150m2 (average ceiling area).

Do-it-yourself

Local major home hardware – $650

For supply and install

Installation costs will also depend on location (metropolitan or regional) and the house design and ceiling accessibility. As a broad estimate – to install 150m2 of R3.5 batts in a metropolitan single storey home with no major obstructions in the attic space would cost in the vicinity of $1,350. If in doubt obtain more than one quote before committing to proceed.

Where can I find more information?

For product information about insulation and its application, contact an established insulation manufacturer either personally or by referencing their website. There is a great deal of useful information and many video clips available on websites.

The Insulation Council of Australia and New Zealand also has useful information available on its website.

You can also check Sustainability Victoria’s Smarter Renovation, which includes tips for choosing the right insulation, steps on how to check your ceiling insulation and easy ways to draught seal your home.

If I already have this feature, is there anything I need to know about using it effectively?

By addressing potential leakage problems, insulation will perform better and less energy will be required for heating and cooling to keep the house comfortable.

Similar to zoning, consider draught sealing and door snakes to close off any leakages in the home. Gaps can be found around external floors, between the floor and skirting boards, around window frames and between the ceiling and cornice.

You can also close windows on colder days to retain the heat gained by insulation or open the windows on warmer days for cross-ventilation to distribute the heat around the home. Check that the right shading or sun control measures are in place.

Does this work better when combined with any of the other 17 Things™

Insulation will perform better with No. 8 Windows like double-glazed windows or WERS rated windows. These reduce the amount of heat loss and heat gain from the wall areas of your home which aren’t insulated – the windows. Insulation is also an important asset to No. 7 Density of Building Materials as it can be added to light or heavy building materials to make them more effective to store and release heating and cool air when needed.

Will this feature be recognised when I sell my property?

Yes; Liveability Real Estate Specialist sales agents and property managers have been upskilled to identify an additional 17 Things™ on top of a standard property appraisal. So if you have invested in any of the 17 Things™ this means your property will be appraised and marketed with real skill and with the best marketing resources for online and print media.

You can book a free property appraisal with a Liveability Real Estate Specialist any time you’re ready to sell or even if you’re not planning to sell for a couple of years. Each of the 17 Things™ has appraisal benchmarks (relevant to existing and new homes) which have been set by relevant industry partners to make sure we deliver a high standard of property marketing. So your Liveability Real Estate Specialist will work through this appraisal checklist with you as they move through your home. It’s a great chance for you to let them know about all the property features you have invested in.

There are two main categories of insulation – bulk and reflective. In tropical climates, reflective foil under roofing material and bulk insulation in the ceiling are the best choices for insulation.

Reflective insulation reflects heat back to where it has come and needs to be installed correctly to be effective. Bulk insulation resists the transfer of heat from one side to the other, relying on air pockets trapped within the insulation.
