AGC Pyrobel^® Vision Line

Seamless butt-glazed fire-resistive safety glass solutions: achieve virtually uninterrupted transparency with UL-Certified 60-120 Minute Temperature-Rise Wall Systems, fabricated in North America

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^® Vision line represents a commitment to delivering high-performance, fire-resistive solutions that act as a total thermal shield. By utilizing advanced butt-glazed technology with a narrow 4mm silicone joint, we empower architects to meet stringent ASTM E119 and UL 263 thermal barrier requirements while achieving expansive, nearly seamless glass walls.

Pyrobel^® Vision Line successfully passes rigorous hose-stream testing, proving its structural integrity under extreme conditions. This innovative system eliminates the need for vertical mullions, offering a clear, uninterrupted field of vision that matches the aesthetics of modern float glass. Its low-iron, high-transparency composition ensures exceptional optical clarity and color neutrality, creating daylight-filled environments that remain cool and safe for evacuation.

Available through our in-house fabrication, the AGC Pyrobel^® Vision line satisfies both ANSI Z97.1 and CPSC 16 CFR 1201 impact safety standards, making it ideal for high-visibility partitions in high-traffic areas. Whether you are designing a contemporary healthcare facility or a sustainable corporate campus, McGrory Glass delivers the precision-engineered, butt-glazed solutions required for modern, eco-conscious developments. We combine the reliability of a national leader with the customized service of a dedicated fabrication partner, ensuring your next project achieves maximum protection with a sleek, minimalist 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
Expansive Office Partitions	Barrier to Radiant Heat (ASTM E119): Blocks thermal transfer to keep egress corridors safe for 45-120 minutes.	Seamless Transparency: Narrow 4mm vertical joints eliminate bulky mullions for an uninterrupted, “all-glass” look.
High-Traffic Medical Corridors	Impact & Sound Safety: Meets CPSC Cat II impact standards while providing superior acoustic insulation for patient privacy.	Daylight Integration: Maximizes natural light flow through large, butt-glazed spans to support healing and wellness.
University Lobby Hubs	Multi-Hazard Protection: Extensively tested for heat-barrier performance, impact resistance, and hose-stream endurance to withstand extreme thermal shock.	Minimalist Aesthetics: Low-iron glass composition ensures clear, color-neutral views that match non-rated surrounding glazing.
Secure Government Facilities	Thermal Separation: Prevents fire and heat spread between secure zones without compromising visibility.	Unobstructed Sightlines: High optical quality allows for 360-degree situational awareness and clear monitoring.

Why AGC Pyrobel^® Vision Line Butt-Glazing?

Seamless Panoramic Transparency

The Pyrobel^® Vision Line system utilizes advanced butt-glazing technology with narrow 4mm vertical joints to eliminate the need for bulky vertical mullions. This design allows for the creation of continuous glass walls with an unlimited number of panels, providing a sleek, “all-glass” aesthetic that maximizes transparency.

Advanced Radiant Heat Shield

Engineered as a high-performance fire-resistive barrier, this system is certified to limit temperature rise to just 250°F above ambient on the non-fire side. By blocking radiant and conductive heat transfer for up to 120 minutes, it ensures that egress corridors remain safe and habitable for emergency evacuation.

Unrivaled Light Transmission

Manufactured with premium low-iron glass, this multi-ply laminated glazing offers up to 88% visible light transmission, ensuring spaces are flooded with natural daylight. The color-neutral composition removes the greenish tint found in standard glass, allowing for a perfect visual match with non-rated architectural glazing.

Robust Acoustic and Impact Safety

Beyond fire protection, Pyrobel^® Vision Line provides a high sound-reduction index of up to 49 STC, making it ideal for private healthcare and corporate environments. The system is fully impact-resistant, meeting stringent safety standards to withstand the rigors of high-traffic commercial settings.

Rigorous Life-Safety Certification

This UL-certified product line has successfully passed rigorous hose-stream and impact testing to ensure structural integrity under extreme conditions. Offering reliable 60-to-120-minute fire ratings, it acts as a high-performance barrier to radiant heat that provides a formidable defense against the spread of fire, smoke, and hot gases.
