Location and climate are very big factors when it comes to home insulation. The South African Highveld for example has an extremely mild climate. My house has no insulation in the ceilings, single pane windows, double brick walls with no insulation and air vents all over the place to the outside. The house was built in the 70s I think, using construction methods appropriate for that time. So ot very modern. I have no climate control in my house. And I don't need any. At the moment I'm considering some ceiling insulation, because in the middle of summer things can get toasty in the evening when the hot roof radiates back into the cool house.
