ISBI is a leading brand of transparent armor. Our new technology AIR-CHAMBER glass ages very well in hot weather. We give a against delamination.
RETURN FIRE GLASS: A 9mm bullet fired from the inside of the vehicle goes out. The round fired from the inside of the vehicle first hits the polycarbonate. This plastic is very soft and does not deform the bullet. The bullet then continues and completely penetrates the glass.
This shoot out capability is ideal for Police Officers. We have molds for Ford Interceptor, Tahoe, Charger, Impala.
This type of system is called One way (return fire or air chamber). ISBIs patent was awarded because our system uses bent glass. So our glass has the exact curvature of the OEM. This is why the windows roll up and down.
This same glass was turned around and stopped 20 9mm incoming rounds. This is a IIIA sample.
Independently certified by Chesapeake Testing Lab in Belcamp, Maryland.
The air gap between the outer laminated glass and the inner laminated polycarbonate prevents this armor from delaminating. It is also a lot lighter (up to 35%) and cooler (up to 50%) than regular glass.
Regular ballistic glass does not have a gap. The polycarbonate tends to delaminate over time, as seen in the picture below
