Bit of a change in mind set!
NZ'ers are really behind the times when it comes to insulation -- we
tend to have terribly badly insulated houses, resulting in homes that
are below WHO guidelines for internal temperature and a lot of
unnecessary illness from cold and damp.
Also, they cost a hell of a lot to heat.
