Why FireDefendTM
Exceptional Optical Clarity & High Light Transmission
Manufactured with premium low-iron glass, FireDefend™ provides superior visual clarity. Delivering up to 89% visible light transmission (VLT), this high-performance safety glass ensures safety does not come at the expense of aesthetics, providing architects with a clear, distortion-free solution for both interior partitions and exterior building envelopes.
Combined Fire & Security Protection
Engineered to resist both fire and physical attack, FireDefend Security combines industry-leading fire-rated glazing with forced-entry-resistant performance in a single system. Solutions are tested to meet recognized fire-rated and security glazing standards, providing comprehensive life-safety protection without sacrificing visibility.
Seamless Steel Framing Integration
Designed for full compatibility with high-performance framing systems—such as Forster steel fire-rated framing profiles—FireDefend™ eliminates the need for heavy, industrial sightlines. By replacing traditional, bulky profiles with precision-engineered slim steel framing, it allows architects to create unified, narrow-profile doors, sidelites, and curtain walls that maintain structural strength, fire safety, and attack resistance in one cohesive assembly.
Versatile & Flexible Configurations
Offered in a wide array of glass constructions, nominal thicknesses ranging from 1.451″ up to 3.119″, and framing options, FireDefend™ can be tailored for doors, sidelites, storefronts, and interior partitions. This incredible design versatility allows the system to integrate seamlessly into both new construction and retrofit projects across commercial, educational, healthcare, and government facilities
Sustainable Energy Efficiency & Durability
Built for long-term performance, FireDefendTM fire-rated security solutions support sustainable building goals and can be configured as Insulated Glazing Units (IGUs). By incorporating IGUs, the system improves overall building thermal performance and energy efficiency, helping projects meet green building initiatives while delivering heavy-duty durability that never compromises safety.
Customizable Without Compromise
FireDefend Security Glass can be combined with decorative glass, one-way vision, privacy options, ballistic protection, and other specialty glazing solutions. Compatible with fire-rated framing systems and customizable for virtually any project, these systems maintain certified fire and security performance while meeting architectural design goals.

As a premier fabricator and national supplier, McGrory Glass delivers the technical expertise, manufacturing capabilities, and project support required for today’s most demanding life-safety applications. FireDefendTM combines fire-rated and forced-entry-resistant glazing into a single solution, providing protection against physical attack while maintaining certified fire performance.
Available in configurations offering 10–60 minutes of forced-entry resistance and 45–120 minutes of fire-resistive, heat-barrier (temperature-rise) protection, FireDefendTM helps architects and building owners achieve both security and code compliance without compromising visibility or design.
To provide a complete opening solution, McGrory Glass also supplies Forster® fire-rated steel framing systems, along with compatible fire-rated doors and hardware. Our in-house print division further enhances each project with custom decorative graphics, privacy glazing, and one-way vision options—allowing every installation to balance life safety, security, and architectural design.
