Reduce your household’s carbon footprint with home insulation!
A well insulated home uses less energy to maintain a comfortable indoor temperature. Lower energy consumption means less fossil fuel is burned and less pollutants are produced into the atmosphere such as sulfur dioxide and carbon dioxide.
To maximise the environmental benefits of insulation, it’s important to insulate the entire home including the ceiling and roof, internal and external walls, under the floors and between floors of a multi-storey home.
If you are installing insulation, consider upgrading to a higher R-Value. The higher the R-Value, the more effective the material is at slowing down heat loss and gain. With higher R-Values, your home will stay more comfortable temperature year round and using heating and cooling appliances will be much more efficient.
Insulation materials – Are they good for the environment?
Insulation products are made from a wide range of different materials including:
- Glasswool (recycled glass materials)
- Polyester (recycled plastic materials)
- Rockwool (crushed rock materials)
Glasswool is predominantly made from recycled glass materials such as flat glass sheets and glass bottles. The rest of the glass is sourced from sand which is an abundant resource. The glass is crushed and spun into fibres which are bound together to form glasswool batts or rolls. If glasswool products are left intact, they can be recycled at the end of their life.
Polyester batts are made mostly from recycled plastic materials such as plastic bottles. Like glasswool, polyester can be recycled at the end of its life. Polyester insulation has no breathable particles, making it an excellent choice for people with asthma or allergies.
Rockwool is made from crushed rock particles and stone dust, sometimes containing up to 95% recycled materials. Rockwool insulation has extremely high fire ratings and will help slow down the spread of fire.
Manufacturing processes for insulation – Are they sustainable?
If you want to choose more sustainable insulation products for your home, consider the manufacturing processes and the strategies that insulation brands have in place for minimising their environmental impact.
The good news is, many insulation companies have revised their manufacturing processes and set targets to reduce energy and resource waste. Look out for zero carbon initiatives and long term strategies when researching the environmental responsibility of insulation manufacturing companies.
One of the leaders when it comes to hitting sustainability targets is Knauf. At Pricewise Insulation, Knauf Earthwool is one of our most popular products for people who want environmentally friendly insulation in Australia.
