Green principles are a big part of Natural Insulation’s mission statement. We’re thrilled to be involved in a home insulation company built on natural principles that contributes to reduced health and energy costs, helping in the long run to save our planet and our families.

From the company’s humble beginnings in 1980 as a producer of one of New Zealand’s first recyclable insulation products, Superfill, to its current position as one of the big home insulation companies in New Zealand, Natural Insulation is proud to offer its customers a comprehensive range of recycled insulation products or products based on green principles.

The company’s own product, GreenChoice has the highest component of recycled product of any home insulation product available today. It is composed of 80% recycled, macerated newsprint. Not only is it green, but it’s also highly efficient in insulating your home.

Researchers at the University of Colorado in Denver compared the energy efficiency of cellulose and fibreglass insulation in a study in the winter of 1989-90. Their findings concluded, “The research suggests that the performance of cellulose versus fibreglass is as much as 38% better. Cellulose achieves a tighter building cavity, allowing less heat loss due to air infiltration.” The report is entitled: The Colorado Study (

The company also offers Terra Lana, an insulation product made from recycled and virgin sheep’s wool at a large manufacturing plant in Christchurch. According to Terra Lana, their product takes seven times less energy to manufacture than fibreglass insulation. That’s got to be good for the planet.

Other home insulation products like GreenStuf and QuietStuf are made from recycled PET plastic, including plastic bottles and bags.

Not only are many of Natural Insulation’s insulation products made according to green principles but they also lead to considerable energy savings in homes and other buildings.

Heating and cooling account for 50 to 70% of the energy used in your home and a leading cause of heat loss is poor insulation. Efficient insulation means less of a drain on heating-related energy resources like electricity, gas, wood and goal.

Managing Director of Natural Insulation, Greg Silvester says NI staff are proud of their commitment to green principles: “We are proud of the company’s commitment to New Zealanders, their health and the health of our planet. We are making a difference.
