Thermal insulation is now a major issue for the housing of tomorrow, and is positioned as a real key economic sector of the 21st century.

The measures set by the Grenelle Environment and the European agreements for the reduction of greenhouse gas emissions, with the government objective of dividing greenhouse gas emissions by 4 by 2050 have made the housing energy renovation a major challenge. In fact, 44% of energy consumption in France is due to buildings. The FFB (French Building Federation) mentions at least 27 million homes (including 6 million in fuel poverty) that will require renovation by 2050.

France validated its new energy model with the energy transition law for green growth promulgated on August 17, 2015. This law sets the medium and long-term objectives of energy production and consumption for the country.
