Thermal insulation work can save several degrees in the middle of winter without having to raise the boiler temperature. Improving insulation brings comfort and reduces the energy bill. Cavity wall insulation, for example, is a good choice when you decide to insulate your house from the outside. It is an effective and above all practical way to limit the work inside your house. No need to redo all the decoration or, outside, to redo the entire facade.
