3news.co.nz has reported (12/08/2015) on new rules that are coming in to ensure all landlords will have to install home insulation by 2019.
Currently, around 900,000 NZ homes are poorly insulated. Tenants pay the price in so many ways for this. The death of toddler Emma-Lita Bourne was partially blamed by the coroner on the damp, cold state home she lived in. While Soesa Tovo was waiting to get transferred out of his cold state house last year, he died of respiratory issues.
Councils currently demand $700 just for the permit for wall insulation which must put off a lot of landlords and home owners.
If your home was built before 1979 it is very unlikely to have home insulation. If built between 1979 and 1991, insulation was optional and most homes opted for ceiling insulation only.
Ceiling insulation should be a priority as it accounts for a vast amount of heat loss. Next wall insulation should be looked at.
Once walls, windows and doors have been sorted, it is then time to check on underfloor insulation. Follow up with ventilation options, and then heating.
