WHAT IS R-VALUE?

 

The insulation R-value is very important. The higher the insulation R-value, the better product will be able to restrict thermal heat from entering or exiting your home through the ceiling. But don’t be fooled, it is not only about the r-value when trying to determine the best insulation materials. R-value does play an important role but should not be the sole purpose of selecting a product.

 

BEST INSULATION MATERIALS AND PRODUCTS

 

All of the above insulating products have a very similar R-value, so now we need to start looking at the other factors that answer the question of what are the best insulation products. Let’s break it down so you can decide for yourself what product suits you best.

 

KNAUF EARTHWOOL WITH ECOSE TECHNOLOGY

 

Knauf is a brown earthwool insulation product that is manufactured in Germany. They have created a mineral wool product that has all the advantages of traditional fibreglass insulation products and enhanced it with ECOSE technology.

 

THINK PINK AEROLITE

 

As mentioned above, think pink aerolite insulation is the most tried and tested product on the market around the world. Additionally, it has excellent acoustic properties that help with noise levels and soundproofing. Think pink aerolite has a good r-value the same as polyester insulation and cellulose. The downside to it is that it is made of fibreglass and although it has no harmful chemical additives to make it acceptable insulation, you don’t want to breathe in the fibres.

 

ISOTHERM RECYCLED POLYESTER

 

Isotherm is a reasonably new product in comparison to think pink aerolite and cellulose fibre. It has been taking the South African market by storm. Additionally, the isotherm r-value is the same as the other two products. Having said that, the benefits you get from polyester insulation outrank the other two insulations.

Firstly, it is the most eco-friendly insulation we have in SA. It is made from recycled PET bottles and is good for the environment. Furthermore, it has absolutely NO CHEMICAL additives to make it an acceptable insulating material. In fact, it is people-friendly insulation. It’s pleasant to the touch. You could actually sleep with it as a duvet on a cold night! For people with allergies, isotherm is definitely the way to go.



CELLULOSE FIBRE

 

Ok now to cellulose. Again the r-value is around about the same as aerolite and isotherm. It is produced from recycled newspapers. If you take a closer look at it you will realize that recycle newspapers don’t have a fire retardant status. Therefore cellulose fibre insulation must be treated with chemicals. As a matter of fact, this is done to pass the fire testing stages. These chemicals include boric acid, borax, lime, ammonium sulphate, aluminium sulphate, ammonium phosphate, mono – and diammonium phosphate, aluminium hydrate, aluminium trihydrate, zinc chloride.
