Heat images can help spot where your house leaks warmth-and money. Red colors signify higher temperatures: While most of the house is well insulated, warmth is escaping along a badly isolated roof beam and the windows. (Photo: Christoph Lehner)
Again, most of the house is well insulated, but heat is lost at the basement level. Sometimes, basement walls are badly insulated in order to reduce construction costs. (Photo: Christoph Lehner)

Cold air enters the house next to the rafters cooling the inner walls of the house. A high difference between a room's air temperature and the surface temperature of its inner walls makes it less comfortable for its inhabitants. (Photo: Christoph Lehner)
