What are the new Building Code changes?

The NZ Building code has recently changed to:

  1. replace the existing climate zones from 3 to 6 so new homes can be better designed and built based on the climate they're in, and
  2. increase the minimum R-value of ceiling, underfloor and wall insulation.

What does this mean for Wall Insulation?

There is almost no change to the current R2.0 that is currently called for. Read more about the Building Code changes here.
