Warm, dry, homes

What is insulation?

This is the material that goes in your walls, underfloor and in your ceiling. Good quality insulation helps keep the heat in during winter and out during summer. This makes your house easier and cheaper to heat properly and more comfortable and healthy to live in.

Sustainability Options was set up by two brothers, Nik and Phil Gregg, who challenge themselves to help make the world better by providing sustainable housing advice to create heathier homes for families.
The altruistic business has been providing support to whānau in Western Bay of Plenty, Kawerau, Ōpotiki and parts of Waikato, and is now expanding to the Rotorua Lakes District.

Whether you’re a tenant or homeowner, you can now ask for a home assessment to see how safe and healthy your home is and find out how to make your home better, warmer, drier and cheaper to heat. 

Nik and Phil are both certified Home Performance Advisors and have extensive knowledge about home performance and creating healthier homes. 

They have also enlisted the expertise of Jo Wills, who’s been involved in the Home Performance Advisor programme since its inception and affordable housing projects in Western Bay of  Plenty. 

Jo will be working alongside community leaders and running local information workshops to tell people about Sustainability Options and how to access the service.
