Why choose Earthwool®?
Whatever your insulation needs, there are plenty of reasons why Earthwool is your ideal solution.
Knauf Insulation’s patented ECOSE® Technology binder results in a much softer, lower carbon and lower VOCs product compared to traditional Glasswool products made using formaldehyde.
The Earthwool® Sound Shield Insulation Difference
The Earthwool® Sound Shield batt range includes a selection densities for metal and timber frame construction, providing options for your individual requirements. This specialist acoustic range of insulation products is available in Basic Performance (11 kg/m³), Ultra Performance (14 kg/m³), High Density (17 kg/m³, 20 kg/m³ and 27 kg/m³) sound absorbing performance levels. Earthwool® Sound Shield batts will also absorb the transfer of unwanted sound from outside to inside the home. Soft to handle and install, Earthwool® is made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.
The Earthwool® Ceiling Insulation Difference
Earthwool® Ceiling batts are available in a range of R-Values to provide good energy saving properties to superior energy performance, enabling you to keep your home cool in summer and warm in winter. It’s made using recycled glass, a sustainable binder called ECOSE® Technology with no added formaldehyde and it comes in pre-cut rectangles at either 430mm or 580mm widths to suit most ceiling joist centres. Plus, installation is quick and easy as Earthwool® Ceiling insulation is soft and less itchy to handle and install.
The Earthwool® Underfloor Insulation Difference
Earthwool® Underfloor insulation with a wind-wash barrier provides a superior solution for improving the thermal performance of timber frame floors. The wind-wash barrier provides protection from air movement under the floor. Adding to the already easy to handle and install qualities of Earthwool®, the insulation can be stapled in place. Earthwool® Underfloor insulation will improve the thermal comfort and energy efficiency of the building in which it has been installed thus keeping it cool in summer and warm in winter. Soft to handle and install, Earthwool® is made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.
The Earthwool® Wall Batt Difference
The Earthwool® External and Internal Wall batt range includes a selection of R-Values providing an opportunity to choose the best thermal performance for your project. Earthwool® External and Internal Wall batts will also absorb the transfer of unwanted sound from outside to inside the home. In addition to sound absorption, Earthwool® External and Internal Wall insulation will improve the thermal comfort and energy efficiency of the building in which they have been installed thus keeping it cool in summer and warm in winter. Soft to handle and install, Earthwool® is made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.

Frequently Asked Questions
What is the fire performance of Earthwool® insulation?
Earthwool® insulation is non-combustible and complies with the requirements of the Australian Standard AS1530.1 1994.
What is the acoustic performance of Earthwool® Ceiling insulation?
All Earthwool® products will provide some acoustic performance, as glasswool insulation comes with inherent sound absorbing properties.
Are vermin or insects attracted to Earthwool®?
No. Earthwool® insulation has been tested to show that it will not sustain vermin or attract insects.
Can I use Earthwool® Ceiling batts in my walls?
No. Earthwool® Ceiling batts are not designed to be used in walls and should not be compressed (squashed). Compressing Earthwool® insulation will reduce the thermal performance (R-Value) of the product and could potentially cause future issues, as the products are designed to recover to their specified thickness.
What product should I use to provide high acoustic performance in my walls?
The Earthwool® Wall products come in a range of R-Values and densities. The range starts at R-1.5, which provides economical energy saving and acoustic performance, and goes right up to R-2.7, which provides ultra-acoustic performance and energy saving.
Why is Earthwool® softer and less itchy than traditional glasswool?
Earthwool® uses a combination of new technologies, which make the product more comfortable to handle. Firstly, Knauf Insulation’s proprietary fiberisation process creates longer strands resulting in less ‘ends’, to reduce mechanical irritation. Secondly, Knauf Insulation’s patented ECOSE® Technology results in a much softer, less ‘crunchy’ and less dusty insulation product compared to traditional glasswool products made using formaldehyde.
Why is Earthwool® brown?
The distinctive brown colour of Earthwool® results from ECOSE® Technology. This natural binding process leads to a natural shade of earthy brown – free from dye or colourants. This is a result of five years of intensive research and development, as part of our commitment to being at the forefront of sustainability. In some cases, if Earthwool® is exposed to UV radiation, it may result in a white bleaching effect, however product performance is not diminished.
How does the use of ECOSE® Technology make Earthwool® more sustainable than traditional glasswool products with formaldehyde?
ECOSE® Technology is more sustainable because it uses a natural resin, which is less energy intensive than traditional formaldehyde binders. With ECOSE® Technology, rapidly renewable, organic materials replace the traditional petro-based chemicals used in standard insulation binders to create more advanced and sustainable products. ECOSE® Technology is formaldehyde free.
What testing has Earthwool® with ECOSE® Technology gone through?
Earthwool® products have undergone a comprehensive and rigorous evaluation to determine their environmental effects and acceptability in use, and indicate that products with ECOSE® Technology improve on the already excellent performance of conventional glasswool products. As with all Knauf Insulation products, Earthwool® has been independently appraised with BRANZ to comply with Australian Standards. Also, Earthwool® insulation is certified by Eurofins Gold as an ‘outstanding material’, according to the VOC (Volatile Organic Compounds) Indoor Air Quality emissions regulations. Earthwool® was awarded Eurofins Scientific’s first Indoor Air Comfort Gold Standard certificate as part of the Eurofins Air Comfort Gold standard testing and certification programme.
Why does the Earthwool® insulation packaging look different in store?
We’re currently in the process of updating some of our packaging, so you may find that the images shown here on our website vary slightly from what you see in store. The products within the packaging are of the same high quality though, so be sure you check the specs on the outside to make sure you’re buying the right insulation for your needs.
