At a time when France is engaged in a period of energy transition and has set ambitious targets for the growth of renewable energy, the use of solar roof panels is a real solution for the future. In effect, the installation of solar panels on flat/pitched roofs adds value to the building’s outer structure and is one of the levers accelerating the energy performance of buildings. A long-term, fit-for-purpose response to the requirements of current regulations: RT 2012, France’s law on energy transition for green growth, Biodiversity law and Climate Energy law. In this context, AXTER has launched a full range of solar waterproofing processes.
