New Zealand Standard for Installing Home Insulation

NZ Standard NZS 4246:2006 - Energy Efficiency - Installing Insulation in Residential Buildings

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.
