Laminated glass consists of two layers of annealed glass bonded together by a tough, pliable and invisible layer of polyvinylbutyral (PVB). This type of glass construction offers important safety & other benefits in automotive applications:

· Objects striking the glass are much less likely to penetrate and enter the vehicle cabin. Laminated glass provides enhanced barrier qualities to outside object intrusion.

· In the event of an accident, laminated glass assists in maintaining the occupants within the vehicle's safer environment.

· In the event of glass breakage, the damage is normally confined to a localized area, thereby preserving visibility in other parts of the window.

· Should glass breakage occur, broken pieces tend to remain intact, even in the area of impact, adhered to the PVB interlayer. This quality of laminated glass protects vehicle occupants by retaining broken glass fragments.

· Made with highly weather-resistant materials, LAMISAFE brand products are virtually unaffected by harmful UV rays and severe temperature variation. They offer clear visibility even after many years of service.


Tempered glass is created by heating annealed float glass to near melting point, rapidly cooling its surface and allowing the inner core to cool naturally. The glass is cut to size prior to heating, shaping and quenching.

Tempered glass is at least five times stronger than ordinary flat glass resisting impact, shock, thermal and mechanical stress. It also can flex more without breaking. Tempered glass is well suited for automotive applications due to its unique fracture characteristic. If broken, it fragments into small and less harmful pieces providing a safer environment in case of accidents.

Looks like the windshield is laminated, the other windows are tempered. So at that point I have no clue what the identifiers might be for acoustic-dampening glass vs non.
