DefendEd^TM for the Education Sector

Fostering Secure Learning Environments through Natural, Student-Centric Design

A normalized environment is critical for maintaining a student’s focus on academics rather than threats. DefendEd^TM systems utilize invisible hardening—advanced multi-ply glazing that mimics standard architectural glass. This removes the visual cues of danger, such as bars or heavy mesh, which is a cornerstone of trauma-informed design. By using durable humane finishes and narrow-profile Forster® Steel Framing, schools can secure entry vestibules and corridors while maintaining the welcoming, residential feel that supports student comfort.

DefendEd^TM by McGrory Glass is engineered for high-traffic educational environments, with primary usage cases focusing on critical “first-point-of-contact” locations and interior transition zones. In K-12 and Higher Education campuses, these systems are strategically installed in entry vestibules, main office partitions, and ground-floor perimeter windows to prevent unauthorized breach. Beyond the building envelope, DefendEd™ is increasingly utilized in interior stairwell enclosures and “safe room” corridors to create secure zones that maintain the human-centered design goal of transparency. By replacing traditional, opaque barriers with clear, attack-resistant glazing, schools can achieve full-vision design, allowing staff to maintain passive surveillance and students to benefit from daylighting and biophilic views without sacrificing life safety.

DefendEd^TM undergoes rigorous third-party testing to meet ASTM F1233 and other forced-entry standards, specifically engineered to withstand sustained physical attacks from tools like hammers, bats, and crowbars for almost 15 minutes. This material construction offers a significant tactical advantage by providing the “gift of time” necessary for lockdown protocols to be successfully initiated. Unlike standard glass, DefendEd^TM maintains its structural integrity even when severely fractured, ensuring that the school’s security remains a modernized, invisible layer of protection that supports both the physical and psychological wellness of the campus community.
