One way Transparent Armor
Transparent armor polycarbonate
  • 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: In the left side you can see how a 9mm bullet fired from the inside of the vehicle goes out and strikes the watermelon. This 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 (then strikes the watermelon, or person attacking you).
  • This shoot out capability is ideal for Police Officers. We have molds for Ford Interceptor, Tahoe, Charger, Impala.
  • The exit area marked with the arrow is compromised by the outgoing round. 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
Delamination   one way armored
Made with a combination of laminated glass, spall protection, air gap and polycarbonate. It is the strongest, yet the lightest glass in the market.
Our patented system of an air chamber technology permits the passengers to shoot through the glass from inside of the vehicle (return fire).  The air chamber also allows the interior of the vehicle to be 50% cooler (less heat transferred) and quieter than the traditional laminated windows.

We export glass kits for all types of vehicles. Our patented glass weighs 35% less than traditional glass clad polycarbonate. 10 year ballistic Warranty.
