Worldwide leader in light and sustainable construction, Saint-Gobain designs, manufactures and distributes materials and services for the construction and industrial markets. Its integrated solutions for the renovation of public and private buildings, light construction and the decarbonization of construction and industry are developed through a continuous innovation process and provide sustainability and performance. To answer these challenges, we must provide materials with complex structures. E.g., new functions are given to the glass by the deposition of thin films like in electrochromic glasses and in thermally insulating glasses. These solutions allow to reduce the energy consumption in buildings and vehicles thanks to saving in air conditioning and heating.
