Research has shown that more than a million New Zealand homes (New Zealand 2005 House
Condition Survey) have either no, or at best inadequate, underfloor insulation. In
some homes, especially those with ill-fitting tongue and groove floorboards, heat
loss through the floor is particularly high. Why? Well, cold air is driven through
gaps in the floorboards, forcing the warm air in your room towards the ceiling. And
the result? A cold, clammy, unhealthy living space.
Our solutions to this problem Generally speaking, there are two types of underfloor
insulation – bulk fill and reflective - and we offer both types. They both work in
slightly different ways though. Most bulk insulators (we use Expol) work by trapping
air within a ‘mesh’ of material. As air itself is poor at conducting heat, when it
is held in position like this it makes a good insulator. Generally speaking, the
thicker these bulk insulators are, the better their insulation properties.
Reflective forms of insulation work by reflecting radiant heat. They come as foils
and the more sophisticated forms - such as Air-cell, the product we use - also have
an air gap between the foil coatings. Foils need an airgap to work and the minimum
requirement is usually 40mm.
