In 2020 the government updated the thermal performance requirements for insulation, with an aim of making our buildings warmer, drier, and up to 40% more energy efficient. For designers, builders, and installers, this means changes to the way insulation is specified and installed. As a result of the change in requirements, the three climate zones have been replaced with six entirely new zones, allowing for a more accurate representation of the temperatures in different parts of New Zealand.
This is great news for overall home health in Aotearoa and with the right insulation system in place, like Bradford’s R7.3 solution, there’s a simple, straightforward process to keep your insulation compliant.
