Forced Entry Protection

 Citadel Storefront solutions offering forced entry protection eliminate the “smash and grab” threat without resorting to unsightly roll down barriers or bars.  And because forced entry protection is inherent in the storefront design, it offers 24/7 protection.

At the heart of the Citadel Storefront is Saf-Glas╩╝s GlasSteel glazing. GlasSteel’s 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. 

That's how our design can take the punishment it does without yielding—even when it breaks, it remains intact and locked in the frame. This protects your assets in the first moments of an attempted entry before law enforcement arrives on the scene (first responders can gain entry using diamond-tipped chainsaws if required).
