Also called athermic windshields, metalized windshields have a transparent reflective coating that helps to deflect most solar (infrared) rays of the sun. The coating is applied during the manufacturing process during the laminating stage. Metalized windshields may interrupt or block radar detectors, tollroad passes, and even some remote garage door openers. Newer versions typically have untreated areas to prevent device blockage, though the areas on the windshield vary from one car model or windshield manufacturer to the next.
