The introduction of the 42 VI network in the coming years gives opportunities to new technologies: Heated Coated Windshield, based on the Iris anti-solar on glass coating, will be a leading technology. Using the metallic layers of the coating, 42 VI power supply enables the windshield to dissipate more than 1000 W/m2, through Joule effect. This leads to an efficient defrosting and demisting. A description of the product structure is provided, including its heating performances, and all aesthetic and safety characteristics. Relations between windshield dimensions, coating resistance and dissipated power is explained. A special feature is discussed: how to combine tollgate windows and the heating function, in order to achieve homogeneous defrosting speed.
