What Is Earthwool Made Of? Material, Performance & Why Perth Buyers Choose It
Share
If you’ve been asking what Earthwool is made of, you’re probably trying to work out whether it’s a good insulation material, how it compares to other products, and whether it’s worth using in a Perth home or shed.
Earthwool is one of the most searched insulation brands in Australia, but many buyers still are not clear on what the material actually is.
This guide breaks it down in simple terms.
What is Earthwool made of?
Earthwool is a type of glasswool insulation. That means it is made from glass-based fibres formed into insulation batts or rolls designed to slow heat transfer.
In practical use, Earthwool is commonly chosen for:
- ceiling insulation
- wall insulation
- underfloor insulation in selected products
- some acoustic applications
So if you’re asking what Earthwool is made of, the short answer is: it’s a glasswool insulation product designed for residential and commercial thermal performance.
Why the material matters
The material matters because it affects how the product performs in real projects.
For most buyers, the important questions are:
- does it insulate well?
- is it suitable for ceilings or walls?
- does it come in the R-value I need?
- is it a good option for Perth conditions?
That’s where Earthwool tends to perform strongly, especially in common ceiling and wall applications.
Where Earthwool is most commonly used
In Perth and WA homes, Earthwool is most often used in ceiling insulation because that’s where the biggest comfort gains usually come from.
Popular options include:
You can also compare broader ceiling options in the thermal ceiling batts collection.
Is Earthwool good insulation?
For many buyers, the more practical question is not just what it’s made of, but whether it’s actually good.

In general, Earthwool is popular because it offers:
- strong thermal performance across common R-values
- wide use in ceilings and walls
- a familiar and well-supported product range
- good fit for Perth residential insulation projects
How Earthwool compares with other insulation options
Earthwool is often compared against:
- Bradford products
- other glasswool batts
- specialty foil-faced products
- blow-in insulation systems

What Earthwool is not
Earthwool is not the same as reflective foil wrap, thermal break sheet products, or rigid board insulation.
That means it is not always the right answer for:
- metal shed heat control on its own
- wall wrap and vapour-management applications
- all commercial roof or cladding assemblies
It’s important to match the product to the application rather than assume one insulation material suits everything.
Why Perth buyers choose Earthwool
Perth buyers often choose Earthwool because it aligns well with the most common home insulation priorities:
- better summer comfort
- improved ceiling thermal performance
- clear R-value options
- practical use in standard residential builds

Final word
If you’ve been asking what Earthwool is made of, the key takeaway is that it’s a glasswool insulation product widely used in ceilings and walls across Australian homes.
For many Perth buyers, the more important next step is choosing the right Earthwool product and R-value for the project. If you need help with that, you can contact Perth Insulation Centre and compare the right options before you buy.
