I am having a single storey extension built and the builder has used 100mm Knuaf Earthwool insulation in an external cavity wall instead of 100mm Rockwool full-fill cavity insulation as specified in the drawings. I am annoyed at this because I understand rockwool is a better product and has better R value.
Jazz q
I've attached a photo of the insulation that's been used by my builder. Remember it's for an external cavity wall.
John D v2.0
The conductivity for rockwool is 0.37 so you're actually getting a better product. Keep quiet and let the builder carry on using it!
Jazz q
John D so to confirm you think the earthwool product is better than rockwool? I always though rockwool was the better product as the earthwool only has an R rating of 2.25
John D v2.0
earthwool is a brand name, look at the packaging in your photos for the product information

Which is better, mineral wool or glass wool?
If you’re considering installing the insulation yourself, mineral wool is considered much easier to handle. Although heavier than glass wool, mineral wool is much easier to cut, move and fit into place. Glass wool on the other hand is limper, which makes it hard to fit into the spaces required.
Which is better for noise insulation: mineral wool or glass wool?
In terms of sound insulation, mineral wool is often the preferred choice for noisy areas. This is because it is much denser than glass wool, so much less sound travels through the insulation.
What is the best insulation for a building?
When insulating a building it is important to ensure you have the best insulation for the job. Fibreglass and mineral wool are two of the more popular types of insulation used in buildings, but both have their pros and cons. We’ve outlined some of the important factors to consider when deciding if fibreglass or mineral wool will be best ...
Why is glass wool used in insulation?
The glass fibres create pockets of air which act as barriers to prevent heat loss because air is a poor conductor of heat. Glass wool can be found in batts and rolls, loose-fill insulation and also within insulation boards.
What is the R value of glass wool?
R-value. When comparing the two, glass wool has a slightly lower R-value of around 2.2-2.7 compared with 3.0-3.3 of mineral wool, which means it is slightly less effective at preventing heat loss through conduction.
How are raw materials treated?
These raw materials are treated in a similar way to glass, in that they are melted at high temperatures until they melt, and then they are spun to form fibres, similar to wool. This wool is then packaged up into batts, rolls or slabs.
Is mineral wool good for mold?
If you’re looking for a moisture-resistant form of insulation, mineral wool is the clear winner. Mineral wool is resistant to water, so it doesn’t get damp and provide good growing conditions for fungi, mould, mildew or other bacterial growth. Glass wool, on the other hand, can get wet and damp, and as well as promoting the growth of fungi, mildew and rot its insulating properties are severely reduced.
