R-Value is the measure of thermal resistance, or ability to resist heat to transfer from hot areas to cold areas. The higher the R-Value, the better your insulation will perform.
A step up from Earthwool® R-1.5, Earthwool® R-2.0 Wall insulation is still an economical choice with improved acoustic and energy saving properties, creating a peaceful environment in your home by absorbing sound and keeping it where it should be. It’s super-soft, made using up to 80% recycled glass, and available in thicknesses to suit 75mm and 90mm timber frames. Plus, installation is quick and easy. As well as providing an efficient result, this product is extremely durable and comes with a 50-year warranty, so will stand the test of time.
Nothing can quite match Earthwool® Wall batts when it comes to ease of installation. The Glasswool batts are of consistent high quality and are super-soft to handle. Detailed instructions come with each pack, ensuring that even the most inexperienced of installers will be able to work productively.
If you’re planning to install Earthwool® Wall insulation yourself, that’s great. We love it when people get into a bit of DIY, and we try to help as much as possible. But before you begin, please download and read the instructions from the link above, check out the short video and tips below, and always make sure you have the right tools on hand.
Below you’ll find a range of handy resources, including Earthwool® Wall insulation product specifications and technical data, installation guide and warranty details. There’s also some more general information covering the ECOSE® Technology behind your Earthwool® insulation and what makes it so superior, as well as useful safety information. Download each resource and take a look.
Earthwool® insulation is non-combustible and complies with the requirements of the Australian Standard AS1530.1 1994.
Most Earthwool® products come with a 50-year warranty. Check the product packaging for more details.
All Earthwool® products will provide some acoustic performance, as glasswool insulation comes with inherent sound absorbing properties.
No. Earthwool® insulation has been tested to show that it will not sustain vermin or attract insects.
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.
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.
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.
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.
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.
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.
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.
