Broadly speaking, thermal insulation consists in keeping heat transfers between a hot and a cold environment to a minimum. For a building, the aim is to maintain a comfortable inside temperature whatever the weather outside. There are many ways of insulating a building, from both the outside and the inside. Good thermal insulation has many advantages :
- reduced energy consumption, and hence lower costs, by reducing the need for heating or air-conditioning,
- greater user comfort,
- a reduced environmental footprint,
- enhancement of the building's energy performance and hence of its value as a property asset.
