The thermal rating of insulation is referred to as the R-value and the higher the R-value the greater the thermal performance. Rockwool is said to have an R-value of 3-4 per inch, whilst Earthwool insulation is 2.2 – 2.7 per inch. This means that Rockwool has slightly higher insulating capabilities than Earthwool.
What is the difference between rockwool and mineral wool insulation?

Does Rockwool need a vapor barrier?
Note that rock-wool insulation only comes un-faced, meaning there’s no kraft-paper or foil barrier. Depending on the situation, you may need to install an independent permeable membrane to serve as a vapor barrier.Is mineral wool insulation itchy?

Article first time published onIs Rockwool cheaper than kingspan?
Pros – Cheaper – less than half the price of the kingspan (this price includes fitting), easier to fit, less likely to get gaps.
Can kingspan be used as loft insulation?
Using rigid insulation board as loft insulation Some people may prefer to use rigid insulation board to insulate the loft space – for example Celotex or Kingspan – the process is pretty similar to above, although you will need less depth to achieve the same insulation levels (than mineral wool).
Is ROCKWOOL a termite proof?
The products also provide a multitude of advantages including excellent thermal performance and sound dampening, high vapor permeability and drying potential for moisture management, as well as resistance to mold and mildew. ROCKWOOL stone wool products are also resistant to termites.
What are the advantages and disadvantages of mineral wool?
It’s hydrophobic, so it won’t absorb water or encourage the growth of mold and mildew. Mineral wool is also very fire resistant and can act as a fire stop. However, like many building materials, mineral wool also has its drawbacks. It tends to be more expensive than fiberglass, often between 25-50% higher in cost .
Is ROCKWOOL a basalt?
Although it can be spun out of a variety of rock types, mineral wool spun out of basaltic rock is recommended for grow rooms. Note: While the trademarked product “Rockwool®” is made out of basalt rock and often used in grow rooms, it’s not a synonym for “basalt mineral wool” in general.

What type of insulation has the highest R-value?
In the construction industry, how well a particular type of insulation resists the flow of heat is represented by a value called “R.” Among insulation types, rigid foam panels have the highest R-value per inch.
Does Rockwool need air gap?
As mineral wool insulation is breathable it does not require an air gap. Although if it is possible to have an air gap, then it is advised that one should be left.
What is the difference between roxul and Rockwool insulation?
