1. Home Insulation: Why Should I Care?

Australia: a land scorched by heat, sunshine, and desert.

This sizzling image has embedded itself so deeply into global culture that many don’t realize that it’s not quite true.

To be fair, we do have burning summers. And our winters are indeed milder than American and European winters.

But indoors – where we spend 90% of our lives – we actually feel the winter cold more than Americans and Europeans. (Not to mention the blistering summer heat.)

How did we end up literally paying for harsher indoor seasons?

And, more importantly, how can we stop paying for them while enjoying more comfortable homes?

The answer to the first question: Australia’s epidemic of inadequate (or nonexistent) home insulation.

The answer to the second: improved home insulation.

While this practice is almost universal in America and Europe, Australian homeowners are often surprised to learn that a well-insulated home is the key to lower electricity bills – or that their home is poorly insulated in the first place.

Some are even scared off of the entire industry by the poorly implemented Home Insulation program a decade ago.

So they accept more extreme indoor temperatures and higher electricity bills.

Fortunately, improving your home’s insulation is simpler and more affordable than most people think. In fact, the typical home recoups the insulation costs within 5-6 years, in the form of 40-50% lower heating and cooling bills. 

But the home insulation scheme did prove one thing: you have to be a well-informed consumer to be able to choose an experienced and qualified installer.

So it’s essential to know

  • The basics of insulation
  • How to find a reliable, trustworthy installer
  • The right questions to ask your installer

That’s why we created this complete resource for Australian homeowners.

This clear, reader-friendly guide provides everything you need to know about how to easily and affordably improve

  • your home’s heating and cooling efficiency
  • your family’s year-round comfort
  • your (lower) electricity bills
