Sheets ahead
Malcolm Wheatley reports on how advanced production processes have enabled automotive glass to be augmented with added-value technologiesFor the most part, glass alone does not provide the capabilities that a driver most values in a vehicle’s glass components. Instead, from road noise reduction to heat-reflective capabilities, and from built-in antennae ...
