Insulation Tips
An Overview of Earthwool Insulation
Dec
If you have researched insulation in Australia in recent years, you have probably come across the brand “Earthwool”. You may have been curious about the name, and wondered whether it was made of sheep’s wool. In fact, Earthwool is a glasswool insulation just like a number of other brands of insulation. However, it does have characteristics that differ from other glasswool insulation. Below is some information on Earthwool which may be helpful when deciding which brand of insulation to use.
Where Does Earthwool Come From?
Earthwool is a trademark of Knauf Insulation, a global company which originated in Germany. It is manufactured from recycled glass bottles and contains no added formaldehyde. Earthwool is imported into Australia from overseas.
What are the Characteristics of Earthwool?
Earthwool is sold as batts or rolls (blankets) with a range of R-values. The insulation is a natural brown colour (no added dyes) and is practically odourless. It is non-combustible and does not absorb atmospheric moisture. It also doesn’t sustain vermin such as rats or mice or encourage mould.
The proprietary technology used to manufacture Earthwool makes it much softer than traditional glasswool, and it is less dusty. This practically removes the “itch” that is associated with installing glasswool insulation. For this reason it is reported to be the most comfortable glasswool insulation to install. Earthwool is supplied in a highly compressed form, which reduces the amount of storage space required.
What Can Earthwool be Used For?
Knauf supplies both thermal and acoustic Earthwool insulation. Thermal insulation reduces heat transfer in and out of your home, making it easier to keep it at a comfortable temperature and reducing energy bills. Earthwool thermal insulation can be used in ceilings, walls and under floors. Insulating the ceiling is one of the best ways of reducing heat loss and gain in your home. Being odourless, Earthwool will not make the roof space smell bad. Earthwool wall batts are pre-cut to fit the most common sizes of wall spaces used in Australian houses. They are also easy to cut with a sharp knife to fit if needed.
Acoustic insulation is used in external walls to reduce sound levels coming into the home, and in internal walls between rooms. As with the thermal wall batts, Earthwall acoustic wall batts fit in most common sizes of wall frames.
What are the Benefits of Using Earthwool?
If you have decided to insulate your home, Earthwool has a number of benefits. It is environmentally friendly due to not containing artificial dyes or formaldehyde. It is soft and comfortable to install. Earthwool comes with a 50-year warranty, meaning it is highly durable. It is highly compressed, meaning you will be able to insulate a greater area with one bag.
Insulating your home can benefit you by lowering energy consumption and unwanted noise levels. Earthwool is a modern brand of glasswool insulation which is comfortable to install.

Would this be suitable for insulating a van?
Hi Summar,
We generally recommend using polyester insulation or Pirmax rigid boards for vans.
Cheers!
Could you use this in/on a boundary fence to stop some of the noise entering the neighbours yard? If not what would be best for outside weather please?
Hi TJ,
Thank you for your question. We would not recommend using Earthwool Insulation in any area that is subject to high levels of moisture, such as outside or underfloor areas near the sea. For these applications we recommend an acousticpolyester insulation product such as Bradford Polymax Acoustic Insulation, as these batts do not absorb any water. It’s hard to know how much it would help to reduce sound in an open area, but you can give it a try. Feel free to contact our team on 1300 729 639 if you have any questions.
Hi Summary, Could I use Earthwool on the inside of my metal small shed and cover it with plasterboard.?
Hi Glenn, thanks for your question. You will need to install a product such as Kingspan Insulshed and allow space for appropriate air gaps before installing the Earthwool Insulation and plasterboard. Feel free to give our team a call on 1300 729 639 if you have any questions.
Cheers,
Christa
Hi,
are rats and vermin known to be attracted to nesting in earthwool insulation? The material is so soft and fluffy, seems ideal for them to nest in. Ceiling is on 2nd level, never had rats on ceiling before, but I want to be sure that rats are not attracted after earthwool installation.
Hi Hok,
Thanks for your question. Earthwool Insulation in particular does not attract rodents or vermin.
Rodents and vermin are not fussy tenants and will nest anywhere that is warm or dry. What we recommend to customers who have a rodent problem, is to engage a pest control specialist to deal with the problem prior to installing insulation and to focus on keeping them away in first place. You can install Earthwool Insulation with confidence that the insulation will not attract rodents.
Feel free to give our team a call on 1300 729 639 if you have any further questions.
Kind regards,
Paul
