New Zealand Standard for installing insulation (NZS 4246:2006)

This Standard is intended to provide clear and sound guidance to installers of insulation to ensure that the design thermal performance and thermal durability of the building element is achieved.

New Zealand has become very aware of the importance of healthy homes and conservation of energy as part of the move to sustainable building.  Insulation correctly installed plays a large part in ensuring efficient use of energy and a healthy internal environment in New Zealand buildings.

If insulation is installed incorrectly, e.g. with gaps, tucking in, or folds, is compressed, bent or becomes wet, the thermal resistance and the durability of insulation will be reduced.
