GreenStuf FAQs

What is polyester?

Polyester is a synthetic fibre, made from polyethylene terephthalate (PET), the same material used to make plastic drink bottles. GreenStuf contains a minimum of 45% recycled polyester fibre from previously used PET drink bottles, keeping them out of landfills. GreenStuf acoustic products can contain up to 85% recycled polyester fibre.
 

Are there any chemicals used in the manufacture of GreenStuf?

No, heat is used to bind the fibres that form the structure of GreenStuf. Some manufacturers of fibreglass insulation still use formaldehyde based binders. Formaldehyde is a known and classified human carcinogen.
 

What does ‘R-Value’ mean?

The R-Value of insulation is the industry standard measurement of thermal resistance. The higher the R-Value the greater the performance, meaning your home stays cooler in summer and warmer in winter.
 

Why is GreenStuf more expensive than fibreglass?

Put simply - you get what you pay for. The raw material, chemicals and processes used to manufacture fibreglass are reflected in the price. However that cheaper material comes at a big cost to performance, health and the environment. The raw materials and manufacturing process used to produce GreenStuf considers much more than just price. GreenStuf is about quality and value. GreenStuf will not deteriorate or break down over time and is backed by a 50 Year Product Durability Warranty. GreenStuf is also completely safe for you, your family and our environment.
 

Can I install insulation myself?

Yes, installing GreenStuf is easy. Installation instructions are included with all of the products. Easy to follow ceiling and underfloor installation videos are also available here.
 

Is there an installation service for Autex Insulation?

Yes, Elite Insulation install GreenStuf insulation in 4 houses every working day of the year! 
 

Why should I choose to use GreenStuf?

Quite simply because it is the best choice. GreenStuf is safe for you and our environment. GreenStuf does not contain chemical additives and will never pose a future health risk to you or our planet. All Autex Insulation products contain already recycled fibre, and remain fully recyclable. GreenStuf is non-irritant, non-toxic and nonallergenic and the fibres are not of a respirable size (i.e. cannot be breathed into your lungs) so they are safe for people living with asthma. GreenStuf will never break down or reduce its performance over time. We think that if you’re insulating, do it once and do it right. GreenStuf is manufactured in New Zealand by Autex, a 100% New Zealand owned and operated family company.
