In short, YES. A non-ballistic application of ACE 200 Series or 300 Series laminates can help retain the structural integrity of a window or entranceway even if penetrated by gunfire and provide resistance against an intruder thereby giving occupants time to move to safety and buying time for law enforcement to arrive.
As always, ACE cautions that no window security laminate (and in fact, no building product) can be considered break-proof, bullet-proof or bomb-proof. A breach may ultimately occur depending on the method and violence of the attack. However, ACE 300 Series laminates have been tested to the UL-S332 standard test method for Burglary Resistant Glazing Material and shown to be effective at reinforcing glass.
