The aim of the TEGAS project is to develop an innovative technology that, through a process using vacuum plasma, will allow the production of prototype windows covered with transparent conductive layer structures, designed as thermal reflective elements and used as components for niche applications of the economy with important advantages compared to the solutions currently existing on the European and international market. The main objective of the project is to obtain prototypes of infrared (IR) and transparent reflective glass in the visible field (VIS) on a real scale that will be tested and validated under similar operating conditions as the real ones. The construction of these glazings uses the technology of thin and ultra-thin layers (thickness of tens of nanometers up to a maximum of 1000 nm) obtained by physical vapour deposition (PVD) processes (e.g. magnetron cathodic spraying), using various cathode materials
