Universal Life-Safety through Invisible, High-Level Protection
BallisticDefendTM achieves human-centered design (HCD) across all sectors by providing protection that is functionally invisible. By eliminating the psychological distress and institutional aesthetics traditionally associated with bullet-resistant barriers, BallisticDefendTM allows occupants to live, work, and heal without the constant reminder of potential violence.
BallisticDefendTM is multi-ply glass-clad polycarbonate security glazing with glass on the attack-side and abrasion resistant polycarbonate on the safe-side, and is produced in three strength levels that meet UL 752 Levels 1 – 8.
Remember, no glass is bulletproof – but BallisticDefendTM security glazing is tested to meet the full range of UL 752 ballistic levels with a result of no spall; no bullet penetration.

UL 752 Certified Protection (Levels 1-8)
Rigorous independent testing ensures that every glass make-up provides a certified shield against specific firearm threats, ranging from 9 mm handguns to high-power 7.62 mm rifles.
Integrated No-Spall Safety
The advanced interior laminate prevents dangerous glass fragments (spall) from breaking off and injuring occupants during a ballistic event, maintaining a safe environment even under fire.
Multi-Threat Performance Capability
This glazing can be customized to include fire-rated, forced-entry, and vision-blocking capabilities, allowing a single unit to meet multiple life-safety and security codes across any sector simultaneously.
Thinner, Lighter Glass-Clad Polycarbonate (GCP)
Our advanced GCP makeups provide maximum ballistic stopping power in a significantly thinner and lighter profile than traditional all-glass laminates, reducing the load on your building’s structural framing.
One-Way Privacy with DotViewTM Compatibility
This feature allows staff or security personnel to monitor the exterior with full situational awareness while preventing outside threats from seeing into sensitive areas or identifying targets.
Safety and Environmental Comfort
Insulating Glass Units (IGUs) combine high-level security with thermal efficiency, providing a robust barrier against ballistic threats without sacrificing building performance.
Customize Your Security Solutions
Our BallisticDefendTM Security Glazing can be combined with fire-rated protection, decorative and one-way-film options, or a customized combination for comprehensive solutions across multiple sectors.
