4. Why Polyester?

Performance / Compliance and Safety

• breathe easy
• non-irritant
• non-toxic
• non-allergenic

Polyester is the name of the fibre extruded from polyethylene terephthalate (PET), a widely used synthetic fibre traditionally used in clothing and bedding. Most of the polyester we use has been recycled from various sources such as plastic bags and packaging.

Polyester does not “leach” any chemicals and is food safe. The polyester fibre we use is the same as that found in clothing and bedding. Polyester is also used extensively in medical applications due to its safe nature.

Polyester fibres do not contain nor produce any ozone depleting substances or gases. They are also odourless and contain negligible volatile organic chemicals(VOCs).

Polyester is classified as “no more toxic than wood”

Its thermal insulation performance has been proven in Polar Fleece® and similar clothing during expeditions to the coldest places on earth.

All of our insulation is thermally bonded and will continue to loft over time, unlike other forms of insulation that use chemical binders that can break down over time resulting in a loss of performance. This also ensures that the insulation in your walls won’t slump down and become ineffective.

It’s also fire safe – Autex polyester insulation exceeds the requirements of the Building Code of Australia, as tested in compliance with AS1530 P3.

Autex polyester insulation is incredibly easy to install. No protective clothing or equipment is required and it comes in widths to suit over 90% of all standard house framing.

Small pieces don’t need to be cut as GreenStuf will easily rip in a straight line across the Batt.

Finally, Polyester is resistant to attack by insects, vermin and other pests and is unaffected by moisture.

Healthy

There are no health concerns associated with polyester fibre: they are non-irritant, non-toxic and non-allergenic. There is no need to use protective clothing during installation and your family’s ongoing health will not be compromised.

Autex polyester insulation contains no formaldehyde based chemical binders which are used in some other insulations. Formaldehyde is a known carcinogen.

As well as being a known carcinogen formaldehyde is also a major asthma trigger. It also has many other health concerns.

Our insulation has no airborne fibres of a respirable size. Absolutely no precautions or protective equipment are needed during installation.
