Eco-friendly Insulation

We have noticed a steady increase in the sales of polyester insulation, namely isotherm insulation. With isotherm being the only 100% eco-friendly insulation product on the market, more and more people are shifting across to this product. Read more on eco-friendly insulation here.

Why is isotherm more eco-friendly than other insulations? 

Well to start off, isotherm is made from a polyester, that has been produced from recycled PET bottles. It does not have any of the chemicals that you find in the cellulose fibre insulation, which you can read more on here. In fact, it is so user-friendly you could use isotherm polyester insulation as a duvet on a cold night and won't have a problem.

Isotherm doesn't have any of the fibres that aerolite insulation is made out of either. The fibreglass is not harmful to you if you have it installed but it is advised to wear a dust mask if you enter your roof to do maintenance. The same with cellulose, it has been chemically treated in order to make it fire retardant so you will need to wear a dust mask when entering your roof.

Having eco-friendly insulation installed in your home

Installing eco-friendly insulation in your home helps you to conserve energy. Insulation acts as a barrier to heat gain and heat loss, especially through the floors, roofs, ceilings and walls. Insulation reduces the exchange of heat through surfaces and orifices such as walls, floors, ceilings and attic.

When a home is properly insulated, less cool air needed to keep the home cool will escape from the house during the hot summer season and less warm air needed to warm up the home will be allowed to escape from the house during the cold, chilly winter season.

Think Green Insulation Johannesburg and Pretoria

There is another eco-friendly product called think green insulation. We have installers of think green insulation in Johannesburg and Pretoria. Think green insulation is a similar product to isotherm insulation except it is made by a smaller company and the r-value of think green insulation is slightly lower than that of isotherm.

If you are working on a budget then think green insulation Johannesburg and Pretoria will work out nicely for you. Isotherm insulation is the Rolls Royce of eco-friendly polyester insulation but it does come with a price tag. 

If you are looking for a think green insulation price or isotherm insulation price, give Home Insulations a call. We can help you choose the right product that suite your budget.

Aerolite vs Isotherm

Aerolite vs Isotherm (R-values)

Take a look at the charts below to see the different between think pink aerolite and isotherm ceiling insulation r-values. People often ask the question “aerolite vs isotherm”. The r-values of the product is very important, it measures the heat flow through the product and how effectively the product with work for you.

The Technical Information on R-values (Aerolite and Isotherm)

R-value – or more commonly known as Thermal Resistance is an indication of the products performance.  A higher R-value will mean a better insulating affect the insulation will have.

• R-value = Thickness of the material
• K-value= Its Thermal Conductivity

The K-value is determined in an accredited laboratory and the thickness of the product is determined by the manufacturer.
A sample of the product will be produced by the manufacturer at a stated density (weight) and will be sent to the laboratory for testing. What needs to be achieved here, is a low K-value (thermal conductivity). The product needs to be a bad conductor of heat flow.
Once the results come back for the k-value, the R-value can measured effectively, example:
A 50mm blanket that has a tested K-value of 0.046:
Thickness 0.05/ K-value 0.046 = 1.08 R-value
As long as the same thickness is used by the manufacturer in his range at the same density as the submitted sample, he can use the same K-value and formula to determin the R-values.
A 100mm blanket example:
Thickness 0.1 / Tested K-value 0.046 = R-value 2.17
The determined R-value’s in the above examples are the product R-value. Remember that the ceiling and roof tiles as well as other roofing materials also have a small insulating affect. So the total R-value of both the insulation materials and the roofing materials must be considered. If you have a 2.17 R-value from the insulation material, and a 0.53 R-value from the roofing materials, you get a total R-value of 2.7.
