ArmourShield is specially designed and constructed to remain resistant under attack. This attribute causes attack weapons to simply bounce off the ArmourShield window, making penetration all but impossible. Even when broken, the tough inner-core of the thick poly-composite will lock the exterior glass layers to enable greater attack resistance.

ArmourShield comes in a number of thicknesses geared to provide a variety of security levels, resulting in protection from physical attack from five to thirty minutes (as detailed under AS3555.1 level 2 when used in an approved framing system).
