Specially engineered glazing designed to resist forced entry, ballistic impact, or blast forces while maintaining visibility and light transmission.

Security glass is specially engineered glazing designed to resist forced entry, ballistic impact, or blast forces while maintaining visibility and light transmission, providing enhanced protection for buildings and occupants against various security threats. This advanced glazing technology combines multiple layers of glass, plastic interlayers, and specialized coatings to create transparent barriers that can withstand deliberate attacks, accidental impacts, or explosive forces while maintaining the aesthetic and functional benefits of conventional glazing. Security glass is fundamental in high-risk applications where it serves as the first line of defense against security threats while preserving natural lighting and visual connections, making it essential for government buildings, financial institutions, schools, retail establishments, and other facilities where occupant safety and asset protection are critical concerns requiring specialized glazing solutions.

Security glass is utilized in various protection applications including government and military facilities where classified information and personnel require protection from espionage, terrorism, and other security threats, financial institutions such as banks and credit unions where cash, valuables, and customer safety require protection from robbery and forced entry, schools and educational facilities where student and staff safety requires protection from external threats and violence, retail establishments including jewelry stores, pharmacies, and high-end retailers where valuable merchandise requires protection from theft and break-ins, corporate headquarters and executive offices where sensitive information and key personnel require enhanced security measures, and residential applications including safe rooms, panic rooms, and high-security homes where personal safety and privacy are paramount. Each application requires specific security glass types and performance levels based on threat assessment and protection requirements.

The types and performance levels of security glass include bullet-resistant glass that provides protection against various caliber firearms and ammunition types, classified by Underwriters Laboratories (UL) standards from Level 1 through Level 8 based on ballistic resistance, blast-resistant glass designed to withstand explosive forces and prevent glass fragmentation during bomb attacks or accidental explosions, forced-entry resistant glass that resists manual attacks using tools such as hammers, axes, and crowbars, hurricane and impact-resistant glass that protects against windborne debris and extreme weather conditions, fire-resistant security glass that combines security features with fire protection requirements, and multi-threat glass that provides protection against multiple types of attacks including ballistic, blast, and forced entry. Performance classification depends on testing standards and specific threat scenarios.

Fun Fact: The first security glass was developed in the 1930s for bank teller windows, and modern security glass can now stop rifle rounds while remaining optically clear, with some systems capable of withstanding multiple impacts in the same location.
