The order of priority for insulating your home should be:
  1. Ceiling
  2. Under the floor
  3. Walls (or if not possible to insulate walls, make sure the curtains are thermal and touch the floor)

Whanganui Regional Health Network, in collaboration with the Whanganui District Health Board and the Energy Efficiency and Conservation Authority (EECA) and other community groups, have supported the insulation of homes in the Whanganui region since 2007, and the government has since become involved in providing home insulation nationally. Whanganui Regional Health Network is helping to coordinate referrals in our region, with one of the criteria being high needs health conditions. The government criteria for receiving help with insulation is found at

One dollar spent in insulation is five dollars saved in health and social security.
