1. The two glass types are radicaly different

Tempered glass, usually used on side windows, breaks into small fairly regular little pieces. You see these ont eh road side when some one has broken a window to get in. Most house patio windows are tempered. the glass won't cut you if you bash into it and it brakes.

Laminated has a sheet of plastic between 2 layers of glass. That makes it hard to go trhough it on impacpt. If used on side windows those glass breaking devices will not destroy the layer of plastic enough to get through. Why you also don't want to use it on patio window or house windo glass. You can sustain major cuts from the large shards left over.

Using laminated on car side windows is not a good thing.
