The new building laws in South Africa stating that all new homes need to be insulated with the appropriate insulation R-value depending on your climatic region. There has been a huge increase in people searching for more eco-friendly insulation products in South Africa.

Think green insulation is another polyester ceiling insulation made in Johannesburg. It is also made out of recycled PET bottles like isotherm. Basically made the same way as isotherm, but a lower quality version.

Think green insulation takes plastic bottles and transforms them into an eco-friendly budget polyester insulation. You can see the thickness of the top of the range 130mm think green in the photo below.

Please Note: Think green insulation is mainly used for low cost housing in South Africa. Its a budget insulation product and is not the preferred option for home use. The density and thickness of the material is not consistent like that of isotherm or aerolite.

Aerolite vs isotherm vs think green

Think pink aerolite is still the most tried and test insulation on the market, with isotherm insulation becoming more popular in recent years. More and more people have been turning to the eco-friendly green polyester insulation nowadays.

Aerolite vs isotherm vs think green? Aerolite and Isotherm have very similar r-values, while think green is quite a bit lower in comparison to the two leading insulation products in South Africa.

  • Isotherm made by Brits, a well-known and recognised insulation manufacturer in South Africa
  • Aerolite is made by Isover who is also a well-known company worldwide
  • Think green insulation is made only in Johannesburg

Think green insulation price is quite a bit cheaper when compared to isotherm and aerolite. This may be due to the fact that the product is of a low quality and does not meet the requirements of the Sans building laws. When you measure the thickness of think green insulation, you will often find that the 130mm is actually around 70mm – 80mm thick.

Think green insulation price

We would advise that if you were to select think green insulation based on price that you go with the 130mm. Think green insulation price per m2 for the 130mm is between:

R58m2 – R64m2 (supplied and installed professionally)

The price does vary a bit between expert insulation installers of the product. The think green price per m2 given here is supplied and installed all inclusive.

To sum it up, if you working on a small budget, think green insulation will work just fine for you. If you want the best of the best insulation, we would advise using isotherm insulation but remember isotherm does come with a price tag so expect to pay a higher price.
