Rear windows in cars differ significantly from front windshields. Unlike laminated glass used for windshields, rear windows are typically tempered glass. This tempered glass shatters into small, rounded fragments when broken, reducing the risk of sharp edges. Additionally, rear windows have electrical defrosters consisting of a metal grid bonded to the glass, which generates heat to clear ice or condensation.
