Thermal insulation
Insulation is the first lever for an effective energy renovation. Insulating the walls, roof, loft and floors limits heat loss, removes thermal bridges and improves comfort in both summer and winter. It's often the most cost-effective work, with a fast return on investment.
Window renovation
Old windows or single glazing are a major source of heat loss. Switching to double, or even triple, glazing, combined with high-performance frames, improves the home's thermal and acoustic insulation while boosting security and looks.
Heating system
Replacing an ageing boiler with a high-performance system (heat pump, condensing boiler) sharply cuts consumption. Combined with good insulation and suitable controls, a modern heating system lowers bills and carbon footprint. Many grants (MaPrimeRénov', CEE, éco-PTZ) help fund this work.
