Isotherm vs Fabufill

Lately, there have been quite a few polyester insulation products emerging on the South African market. Not all polyester products have been created the same. Take a look at the difference between isotherm vs fabufill aka Platinum Fiber Insulation.

Isotherm vs Fabufill Insulation R-value and density

When selecting an insulation product to install in your roof, you should always check the r-value. The higher the r-value the more thermal and acoustic properties it will have. You will also need to take the density of the product into account. The 10kg density has a much lower insulating effect than the 11.5kg density. Therefore you should get the 10kg density for much cheaper than the 11.5kg.

Let’s take a look at the difference between the two products.

isotherm vs fabufill insulation think greenIsotherm Insulation

40mm = 0.82 (10kg density)
50mm = 1.02 (10kg density)
75mm = 1.53 (10kg density)
100mm = 2.33 (10kg density)
135mm = 3.14 (11.5kg density)
145mm = 3.37 (11.5kg density)

Fabufill (Platinum Fiber Insulation)

40mm – 0.94 (10kg density)
50mm – 1.15 (10kg density)
75mm – 1.69 (10kg density)
100mm – 2.20 (10kg density)
135mm – 2.70 (10kg density)

Notice how the top of the range isotherm products have a much higher r-value and density than the fabufill products. Most homeowners don’t not enquire about density and select a product based on price. Remember to also use an insulation specialist to install for you.

It is difficult to put fabufill in the same class as isotherm because it has a much lower density. Therefore the price to get you roof insulated with Platinum Fiber should be much lower than isotherm. Read more on how a homeowner can think green with insulation.

Very rarely is cheaper better. If you get the right product installed the first time you won’t have a problem in the end. Do some research beforehand and only install the best insulation products.
