Forster fuego® light: Expansive glass and slim steel profiles for up to 120 minutes of limitless, fire-resistive safety.
The Forster fuego® light system provides high-performance fire-resistive protection for North American commercial and institutional architecture, carrying Intertek listings for 60- to 120-minute durations. As a UL 263 and ASTM E119 listed wall assembly, the system is not subject to standard opening-protective size restrictions, allowing for expansive, safe glazed surfaces. This slim-steel framing utilizes ultra-clear AGC Pyrobel® glazing to maintain optimal clarity within narrow sight lines while meeting rigorous hose-stream and positive-pressure safety standards. Architects can achieve a high-end aesthetic through concealed hardware options—including hinges and closers—and the AGC Pyrobel Vision Line butt-glazed system that features an ultra-slim 4 mm joint. Each system is supplied as a fully fabricated K/D assembly with factory-installed hardware packages, ensuring precise integration and reliable multi-hazard protection in demanding environments.
 Target Environment |
 Key Threat Mitigation |
 Visual Goal |
|---|---|---|
Main Entrances & Public Lobbies | 60-120 minute fire-resistive protection (ASTM E119/UL 263). | Welcoming, transparent first impression with slim steel framing and large low-iron glass panes. |
Interior Stairwells & Exit Corridors | Fire-resistive wall assembly certification that blocks radiant heat transfer. | High natural light for occupant wellness and safety via narrow-profile sightlines. |
University Hubs & Atriums | Multi-hazard protection (Fire, Positive Pressure, and Hose-Stream) for high-occupancy zones. | Modern, open architectural aesthetics using “Vision Line” butt-glazed joints for seamless views. |
Healthcare & Lab Partitions | Full wall-assembly listing (UL 263) allowing for expansive glazed surfaces without typical size restrictions. | Clear views for patient/staff awareness through ultra-clear AGC Pyrobel® glazing. |
Secure Access Points | Integration with access-control systems via electrified hardware and tubular exit devices. | Sleek, high-end finish with concealed hinges and closers for a professional atmosphere. |

Why choose Forster fuego® light steel fire-rated framing by McGrory Glass?
Superior Fire-Resistive Performance
This system is Intertek-listed for 60- to 120-minute fire ratings and is classified as a fire-resistive wall assembly under UL 263 and ASTM E119. Unlike fire-protective systems, it blocks the transfer of radiant heat, ensuring that temperature rises on the non-fire side remain below strict safety limits. Because it is listed as a wall assembly, it is not subject to the same opening-protective size restrictions as standard fire-rated windows.
Expansive Glass with Narrow Sight Lines
Forster fuego®light is engineered to support large individual panes of AGC Pyrobel® Fire-Resistive Glazing while maintaining slim steel profiles. This allows architects to design floor-to-ceiling glass walls that maximize natural light and maintain modern, open architectural aesthetics. The combination of ultra-clear, low-iron glazing and narrow sight lines provides an institutional-grade safety barrier that looks virtually invisible.
Seamless Hardware Integration
McGrory Glass provides factory-installed hardware packages that include high-end, concealed options to preserve the system’s clean lines. Features include concealed hinges, concealed closers, and tubular exit devices with ladder pulls. These integrated components are designed to work together perfectly, meeting both aesthetic demands and rigorous fire-safety standards.
Fully Fabricated Assembly for Precision
To simplify the construction process, the frames are supplied as fully fabricated K/D (knock-down) assemblies. This factory-controlled fabrication ensures that every component meets the precise tolerances required for fire-rated certification while reducing labor time on the job site. It provides a reliable, “plug-and-play” solution for contractors handling complex safety installations.
Versatile Design and Finishes
The system is available in a stock range of TGIC-free powder-coat colors, custom colors, and brushed or polished stainless steel for door applications. This allows the fire-rated system to blend perfectly with other non-rated architectural elements within a building. Its multi-hazard protection capabilities—including hose-stream and positive-pressure resistance—ensure it performs in the most demanding North American environments.
Advanced Butt-Glazed Vision Line Option
The system offers an AGC Pyrobel® Vision Line butt-glazed option, which features an ultra-slim 4-mm vertical joint. This eliminates the need for vertical mullions between glass panes, creating a continuous glass ribbon effect for a seamless visual experience. This specialized design is ideal for high-end corridors and university hubs where transparency is a primary design goal.
