For too long New Zealand houses weren’t built with insulation and double glazing.
The original bits of our home are more than 80 years old but several alterations have made better use of the sun and provided better protection from the cold than the original building had.
The last involved fairly radical surgery with good insulation put under the floor, in the walls and roof. All new windows were double-glazed and the old ones retro-fitted.
Now that winter’s here I’m very grateful for all of that.
