Lately there have been quite a few polyester insulation products emerging on the South African market. Not all the 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.
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. This usually backfires on them and they realise this shortly after getting the product installed. 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 before hand and only install the best insulation products.
