Homes in New Zealand must have adequate insulation, so you need to make sure
they have the correct level of thermal resistance (R-value) for their location.
All buildings constructed at Frontier Estate are required by clause 4.5(i) of the
building covenants to have no less than 150% of thermal insulation required by
H1 of the New Zealand Building Code for the Te Awamutu region.
Besides providing year-round comfort, a well insulated home costs less to heat
and cool. With the added benefit of exterior noise control.
A fully insulated home needs about half the heating an uninsulated home requires.
It provides a healthier environment and also helps reduce condensation, damp and
mould. Insulation reduces the rate heat is lost through ceilings, walls and floors. It
traps air in small pockets and provides a barrier to stop heat from escaping.
In poorly insulated homes, 30–35% of heat is lost through the roof, 21–31% through
the windows and 18–25% through the walls. The floor and air leakage account for
the remaining heat loss.
