Didn’t insulation requirements already change?
You’re spot on, nice catch! Ceiling and underfloor insulation has been compulsory in all rentals since 1 July 2019.
To meet the healthy homes standards some existing insulation may need to be topped up or replaced.
Insulation needs to meet the R-values for your area
So, what are R-values? The “R” stands for thermal resistance. R-value is a measure of how well insulation resists heat flow. The higher the R-value, the better the insulation. Living in Hokianga is a bit different from renting a house in Invercargill. That’s why the minimum standards for insulation are different across New Zealand’s three key climate zones.
- Zone 1 - ceiling R 2.9
- Zone 2 - ceiling R 2.9
- Zone 3 - ceiling R 3.3
- Nationwide - underfloor R 1.3
