Rigorously Tested for Maximum Fire-Resistive Transparency
As a premier fabricator and national supplier, McGrory Glass provides the technical expertise and manufacturing scale necessary to secure complex architectural projects. Our specialized fabrication of the AGC Pyrobel® line represents a commitment to delivering high-performance, fire-resistive solutions that act as a total thermal shield. By blocking radiant and conductive heat transfer, we empower architects to meet stringent ASTM E119 and UL 263 thermal barrier requirements, ensuring exit corridors and stairwells remain cool and safe for evacuation.
Providing 45 to 120 minutes of fire resistance, Pyrobel® successfully passes rigorous UL 10C positive pressure and critical hose-stream tests to effectively contain fire, smoke, and hot gases. Unlike standard fire-rated options, its low-iron, high-transparency composition delivers exceptional optical clarity and color neutrality. This provides a clear, distortion-free solution for both interior and exterior applications that seamlessly matches the aesthetics of modern float glass.
Available through our in-house fabrication in stock or cut-to-size formats, AGC Pyrobel® satisfies both ANSI Z97.1 and CPSC 16 CFR 1201 impact safety standards for high-traffic areas. Whether you are designing a healthcare facility or a sustainable corporate campus, McGrory Glass delivers the precision-engineered glazing required for modern, eco-conscious developments. We provide the reliability of a national leader with the customized service of a dedicated fabrication partner, ensuring your next project achieves maximum protection without compromising on design.
Note: AGC Pyrobel® is a fire-resistive glazing solution fabricated by McGrory Glass. Unlike fire-protective glass, Pyrobel® acts as a total thermal barrier, meeting the stringent Temperature-Rise requirements of ASTM E119 and UL 263 for applications where radiant heat must be blocked to allow for safe evacuation.
 Target Environment |
 Key Threat Mitigation |
 Visual Goal |
|---|---|---|
Exit Corridors and Stairwells | ASTM E119 / UL 263: Blocks radiant heat transfer to keep egress routes below 250°F rise. | Safe Passage: Large, transparent spans that prevent panic by visually connecting exit routes. |
Healthcare Fire Barriers | Multi-Hazard Protection: 60-120 minute fire-resistance combined with high-level acoustic insulation (up to 49dB). | Patient Comfort: Maintains quiet, healing environments with maximum natural light and visibility. |
Educational Separation Walls | Impact & Thermal Shielding: CPSC Cat II impact safety + full thermal barrier to protect students from radiant heat. | Open Learning: Replaces restrictive opaque walls with clear glass for better campus supervision. |
Server Rooms & Data Hubs | Heat Sensitive Protection: Prevents external fire heat from damaging sensitive electronics and hardware. | Sleek Protection: High-quality, distortion-free glass that complements modern tech-driven interiors. |

Why AGC Pyrobel® Fire-Resistant Safety Glass?
Ultimate Barrier to Radiant Heat
As a high-performance fire-resistive product, AGC Pyrobel® acts as a total thermal shield that blocks the transfer of radiant heat. This allows it to meet stringent ASTM E119 and UL 263 standards, ensuring that one side of the glass remains cool enough for safe passage even during a 120-minute fire.
Superior Optical Clarity
Manufactured with low-iron glass, Pyrobel® provides exceptional visual clarity and color neutrality without the greenish tint common in standard glazing. This ensures that safety does not come at the expense of aesthetics, providing architects with a clear, distortion-free solution for both interior and exterior views.
Human-Impact Safety and Rigorous Durability
Engineered to meet ANSI Z97.1 and CPSC 16CFR1201 (Category I and II) impact safety ratings. It is an ideal choice for high-traffic areas such as doors and sidelites, where it provides robust protection against accidental impact while maintaining its fire-resistive integrity.
Eco-Conscious and Sustainable Design
Pyrobel® supports green building initiatives and LEED certification goals by being Red List free and a low-emitting material with no VOCs. With an Environmental Product Declaration (EPD) available and a Cradle to CradleTM Silver certification, it is a sustainable choice for environmentally responsible construction.
Versatile Architectural Integration
Approved for use in any standard fire-rated framing system with the same rating, this glazing offers seamless integration into a wide variety of architectural designs. McGrory Glass provides the product in both stock sheets and custom cut-to-size formats, including configurations for both interior partitions and exterior building envelopes.
Third-Party-Certified Performance Standards
AGC Pyrobel® is fully certified to pass the UL 10C positive pressure test and the rigorous hose-stream test, ensuring it remains intact under extreme thermal shock and pressure. This provides 45 to 120 minutes of reliable life-safety protection, effectively containing fire, smoke, and hot gases within the area of origin.
