Environmental Statement
Earthwool® insulation is a high performance product with environmental and sustainability credentials. Earthwool® insulation is manufactured using the latest state-of-the-art technology, industry leading innovation and certified manufacturing processes to deliver one of the most sustainable and environmentally friendly glasswool products available in Australia.
OUR SUSTAINABILITY CREDENTIALS
Environmental Product Declarations (EPD)
Earthwool® insulation supports environmental claims with market leading Environmental Product Declarations (EPDs). The EPDs supporting Earthwool® insulation are one of the most comprehensive evaluations of any insulation product in Australia. The five separate, independently certified EPDs provide clarity and transparency about the life-cycle and environmental impact, a declaration making Knauf Insulation market leaders in product declaration.
CodeMark™ Certification
Earthwool® insulation also maintains CodeMark™ certification. This is the highest level of Building Code compliance in Australia. The Australia Building Code requires insulation to have 50 years durability. The CodeMark™ certification is an independent certification that supports the performance and durability of the products for at least 50 years.
Eurofins Gold Certification
Earthwool® insulation is supported by Eurofins Indoor Air Comfort Gold as an “outstanding material” according to VOC and Indoor Air Quality Emissions certification.
The ECOSE® Technology that is used to manufacture our products replaces the phenol formaldehyde that is used by other Australian manufacturers. Phenol formaldehyde is a known carcinogen and even low levels are considered unacceptable by leading air quality certification organisations. This places Earthwool® insulation in a unique position and makes it impossible for our competitors to currently match this level of certification.
GreenTag Certification
Earthwool® insulation is supported by GreenTag Level A certification. GreenTag is one of the leading independent eco certification organisations. Not only does it demonstrate Earthwool® insulation's environmental credentials, it also helps achieve Green Star building certification.
EUCEB Certification
Earthwool® is manufactured using EUCEB certified glasswool. Products bearing the EUCEB trademark are continually monitored and independently classified as being bio-soluble. Specifiers, installers, building owners and the public can have complete confidence in glasswool products that carry the EUCEB trademark.
Recycled Raw Material
Earthwool® insulation is manufactured using up to 80% recycled glass that is made up of post-consumer glass bottles rather than plate glass from the window industry. This process removes glass bottles from landfill, turning them into high performance, energy saving Earthwool® insulation products.
Zero Waste to Landfill
The plants that manufacture Earthwool® wall and ceiling insulation send zero waste to landfill. This achievement marks a significant milestone in Knauf Insulation's sustainability journey, in which they are constantly developing their products and processes to contribute towards greener and more energy efficient environments.
