Insulgard Security Products lineup of ballistic windows and architectural aluminum framing systems are engineered to deliver a full spectrum of ballistic protection for justice, civic, and high‑security environments. Designed for applications ranging from punched openings to full storefronts, each system pairs with Insulgard’s BULLETBLOCK glazing to meet specific project requirements.
All BULLETBLOCK window systems are tested and listed by Underwriters Laboratories to UL 752 Levels 1 through 8, ensuring verified ballistic performance. Systems can be shipped fully assembled for rapid installation or broken down to simplify transport and staging.
Insulgard emphasizes that ballistic performance begins with the frame itself. The company’s aluminum framing meets UL 752 standards—the most widely recognized benchmark for bullet‑resistant assemblies in the United States—providing a dependable foundation for secure window, wall, and door configurations.
When combined with BULLETBLOCK glazing, the systems are designed to:
- Protect people and property in settings such as courthouses, medical clinics, and other indoor or outdoor public environments
- Deter criminal activity, including violent incidents and theft
- Reinforce a sense of safety that supports positive public interaction
The product line’s flexibility allows architects, glazing contractors, and builders to configure secure openings in a wide range of sizes and dimensions.
