Have you ever heard the saying “The road to hell is paved with good intentions”? Well, apparently this is the case with the government rebate on insulation. The good intentions were to help millions of Australians save up to 40% off their cooling and heating bills. The road to hell is all the trouble the demand for insulation had caused.

If you, too, consider using the free insulation offer, here is what you need to be aware of: the material used for insulation matters. Even though the company you employ to insulate your roof should be using only the approved materials that comply with Australian standards, there could be mess-ups. Two words that should be a red-light warning signal for you are Formaldehyde and Foil.

The dangers of Formaldehyde

Here Nelson Larrosa from The Demand Group explains why Formaldehyde – a toxic chemical – is especially dangerous: “FORMALDEHYDE is the next dirty word that should be on everyone’s lips and if you care anything about your health, your families health and our environment, you’ll say NO to this chemical!

What does that actually mean? In Australia, there are lots of products that will contain formaldehyde in very minute quantities. Our standards only allow for products to contain very small quantities of this very harsh substance. Bodies are embalmed using this fluid, it is a known carcinogen and detrimental to the health of those who are exposed to it. The level and length of exposure will determined the severity of the illness.

So why am I telling you this? Because there are lots of imported insulation products coming into the country that contain high levels of Formaldehyde and whilst we haven’t tested any samples, there are reports of installers being violently ill whilst installing imported batts. The Formaldehyde gives off a very strong odour and this is exacerbated in a confined space, like a roof cavity.

There are many countries, like the US and Canada that have banned certain products due to them containing Formaldehyde. We have Australian Standards and all imported products should meet these standards, however this is somewhat questionable give the products we’ve seen on shelves and being installed.

Again when choosing an installer for your insulation and the product that you’re about to purchase, beware! Choose an Australian made product, preferably one that doesn’t use formaldehyde in the process to manufacture or that is used as a bonding substance. Polyester batts manufactured in Australia do not contain formaldehyde and are by far the healthiest option available.

I hope you can use this information. I have never really worried about formaldehyde until the rush of imports and the distinct odour that is associated with it. However, I would just use my nose to let me be the judge. Formaldehyde is a silent killer and I don’t want to find out that my not so keen nose missed something.”

The dangers of foil insulation

And now let’s move on to another dangerous kind of insulation – foil insulation. According to Archicentre, use of foil insulation over ceiling joists or beneath rafters in homes can conceal structural faults and make it almost impossible for inspectors to find potential electrical, plumbing or termite problems.

While it is true that in new homes foil installed in the roof contributes to energy efficiency, we must know that retro-fitting it inside existing homes creates a whole set of issues with locating and fixing faults, and with safety.
