Healthy homes and energy efficiency
Insulation correctly installed is a key part in achieving compliance with the New Zealand Building Code and ensuring that houses can be efficiently heated to provide warm, dry, and healthy living.
NZS 4246:2006 provides guidance to insulation installers to help achieve the design thermal performance and durability of building elements, and to minimise the risk to installers and home owners. The Standard covers:
- methods of installing common insulation products in common residential construction types
- both the installing of insulation in new buildings during construction and the retrofitting of insulation in existing buildings.
Users of the Standard include insulation installers and homeowners who retrofit insulation. The Standard is also the compliance document for the Energy Efficiency and Conservation Authority’s Warm Up New Zealand: Heat Smart programme.
