Aerolite VS Isotherm (R-Value)
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 vs 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 determine 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.
