Installation Video and Downloads

Nothing can quite match Earthwool^® Ceiling batts when it comes toease of installation. The Glasswool batts are of consistent high quality and are super-soft to handle. The ceiling batts are pre-cut to handy widths of either 430mm or 580mm – built to suit most ceiling joist centres. The batts can also be installed from either below ceiling joists (from within the room) or above ceiling joists (from within the ceiling). Detailed instructions come with each pack, ensuring that even the most inexperienced of installers will be able to work productively.

Frequently Asked Questions

ExpandWhat is the fire performance of Earthwool^® insulation?
Earthwool^® insulation is non-combustible and complies with the requirements of the Australian Standard AS1530.1 1994.
ExpandWhat warranty does Earthwool^® have?
Most Earthwool^® products come with a 50-year warranty. Check the product packaging for more details.
ExpandWhat 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.
ExpandAre vermin or insects attracted to Earthwool^®?
No. Earthwool^® insulation has been tested to show that it will not sustain vermin or attract insects.
ExpandCan 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.
ExpandWhat 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.

How drywall and insulation work together
ExpandWhy 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.
ExpandWhy 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.
ExpandHow 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.
ExpandWhat 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.
ExpandWhy 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.
