Sustainable insulation products are not only environmentally friendly, they can dramatically boost your home’s energy rating.
The most eco-friendly insulation materials are Glasswool, Polyester, Sheep’s wool, Cellulose and Earthwool.
Glasswool
Glasswool, also known as fibreglass, is the most cost-effective option. It is naturally fire retardant, does not rot or attract vermin, and is made from recycled glass bottles and sand.
Polyester Insulation
Polyester Insulation can be misleading as it doesn’t sound like a sustainable solution. However, it can be continually recycled because it is polyester. In addition, this product is generally made from recycled plastic bottles and does not have any dust particles or breathable fibres, making it suitable for people with respiratory issues.
Sheep’s Wool
Sheep’s wool is the ultimate in sustainability, being both natural and infinitely renewable. As an insulator, it has some unique properties: it is particularly good at regulating humidity and acts as a natural air filter, absorbing harmful substances from the atmosphere. Its fibres trap air to provide an excellent thermal barrier and sound insulator.
Cellulose Insulation
Made from recycled newspapers, cellulose insulation is an affordable option with resistance to air leaks. However, it can burn quickly, even if treated with a fire-retardant chemical.
Earthwool insulation
Earthwool is free of chemicals, such as phenol, formaldehyde, acrylics and artificial colours. It is fire resistant and made from renewable, bio-based materials. It is relatively new to the Australian market but already very popular.
