Ballistics Protection

Citadel Storefront solutions with ballistics protection resist bullet penetration while protecting against spalling. Bullet-resistant glazing products are available to address three ballistic threat levels.

The internal polycarbonate layer is bonded to the glass with a patented adhesive process to ensure that even if the glazing breaks, every piece of glass—no matter how small—remains locked in place. Testing at Quantico Marine Base in Virginia demonstrated that the 9/16th-inch glazing offered in the Citadel solution stands up to .22 and 9 mm bullets, hand grenades detonated at three feet, and Claymore mines detonated at 75 feet.
