SentryGlas is superior to tempered glass. Tempered glass is stronger than traditional
glass. It is manufactured with built-in stress which gives it added strength.
It's designed to shatter predictably into small pieces. |
Applications. SentryGlas is ideal for fleets, especially
delivery and emergency vehicles. During 1994, the New York City Fire Department
began installing SentryGlas on its new trucks. Other fire and police departments
are expected to begin testing SentryGlas in some of their vehicles. |
| However, these small pieces can become airborne and cause injury to vehicle occupants. When SentryGlas is laminated to tempered glass, it combines the strength of tempered glass with outstanding penetration resistance, preventing broken glass pieces from entering the vehicle. |  |
SentryGlas is available as aftermarket replacement glass. It is a "drop-in replacement," done easily and quickly by pulling out the existing glass and dropping in the SentryGlas. For original equipment applications, no existing designs are necessary |
|
Double protection. While offering protection from flying
glass caused by the impact of an airborne object or an automobile collision,
DuPont SentryGlas also provides a viable deterrent to theft and vandalism.
Due to its high penetration resistance, SentryGlas makes it difficult for
burglars and carjackers to gain entry to a vehicle by breaking the glass.

to accommodate SentryGlas. Automobile manufacturers, aware that security and safety issues are among the top reasons for vehicle choice, are presently considering its use as original equipment for side and rear windows. |
|
To accommodate various application requirements, four types of SentryGlas are available:
