Mainly because the other window is glass, too. The side windows are laminate (and pretty crazed).
You miss understand scuba . 6mm lam ,is glass . go see you local glazier. Just give him a pattern and they should be able to cut the laminated glass for you on the spot .
Its classed as safety glass . It won't shatter ,just cracks ,but stays in tact .
Its ts two layers of float glass glued together ....... Good stuff .
It's really 6.38 mm The .38 is the glue / film that bonds it together ....
