Heat loss and air conditioning losses can be highly significant. Roof insulation in homes makes a considerable difference in winter avoiding heat loss and can contribute to keeping homes cooler in summer.
Roof insulation are relatively cheap to install with a reasonable payback time on expenditure, it is one area of energy efficiency that should be a priority in saving energy and money.
A number of different materials are available, including fibreglass matting, spun mica as well as eco-friendly recycled material.

Cool coating paints that contain pigments to reflect sunlight can also make a sizeable savings contribution to reducing air conditioning needs in summer.
Double-glazing of windows makes a significant difference to both noise pollution and heat loss. Extremely popular in colder climates, in South Africa the payback time on expenditure will be longer, and extensive research needs to be undertaken to find the right solution for your home.
