Advancing Healthcare Healing through Compassionate, High-Security Design

DefendMedTM by McGrory Glass represents a paradigm shift in healthcare and behavioral health security, moving away from restrictive, institutional barriers toward a human-centered design (HCD) philosophy. Purpose-built for the rigorous requirements of acute care and psychiatric facilities, DefendMedTM achieves the critical goal of normalization by replacing punitive features like heavy metal screens or bars with clear, attack-resistant glazing. These systems are primarily installed in patient room windows, secure nurse stations, observation partitions, and high-traffic corridors to create spaces that feel more like residential or hospitality environments. This innovative approach prioritizes healing-centered design, utilizing full-vision glass to eliminate the psychological stressors of traditional security, thereby supporting patient de-escalation and providing staff with essential passive surveillance capabilities. By ensuring patients have unobstructed biophilic views and access to circadian lighting, DefendMedTM leverages design elements clinically proven to reduce agitation and improve recovery times.

The material construction of DefendMedTM utilizes advanced proprietary interlayers and laminated safety glass, specifically engineered to provide a durable humane finish that resists both physical assault and self-harm attempts. These units undergo stringent third-party testing to meet ASTM F1233 standards, ensuring they can withstand sustained force for 15 to 60 minutes. A critical benefit for clinical settings is the non-spall performance, which ensures the interior side remains free of dangerous glass fragments during an impact. Furthermore, DefendMedTM is designed for Holistic hygiene, featuring non-porous surfaces compatible with hospital-grade disinfectants and anti-microbial coatings. The system also provides significant acoustic dampening (STC 38+), creating the calming, light-filled, and quiet atmosphere necessary for a patient’s mental and physical rehabilitation without compromising life safety.
