In modern building safety, fire-rated glass stands as a critical line of defense, designed to compartmentalize flames and smoke, protect escape routes, and provide crucial time for evacuation and emergency response. However, the performance of this specialized glass is entirely dependent on a seemingly minor yet utterly indispensable component: the fire-rated gasket.

Significant differences exist in key performance parameters between Nano-Silicon composite fireproof glass and traditional fireproof glass (such as laminated fireproof glass and grout-filled fireproof glass). The following comparison table and selection advice aim to provide a clear understanding for informed decision-making.

Shanghai, August 2, 2025 – The Xuhui Aerospace R&D Complex has successfully completed installation of Pyronano’s advanced fire-resistant glazing systems, marking a milestone in both project execution and technical collaboration. The seamless integration of custom-shaped A-Class partitions, curved fire barriers, and multi-category fire doors across mission-critical zones demonstrated Pyronano’s engineering rigor, earning recognition from architects and safety auditors alike.

Building emergency exits serve as the lifelines of any structure during fires, transforming chaotic evacuations into orderly escapes. The integration of fire-resistant glass in these critical pathways—stairwells, corridors, and exit doors—is not merely a compliance measure but a scientific survival strategy. Here’s how this technology redefines safety in modern architecture.

In high-rise buildings, stairwells serve as critical evacuation arteries during fires. Unlike horizontal exits, these vertical pathways face unique dangers: chimney effects that accelerate smoke spread, thermal shock from firefighting water, and structural compromise risks. Fire-resistant glass transforms stairwell enclosures from passive passages into actively shielded lifelines, merging safety engineering with architectural necessity. Here’s how this technology redefines survival in multi-story emergencies.

Fire-rated glass acts as an intelligent barrier, maintaining structural integrity even at temperatures exceeding 1000°C. Unlike ordinary glass (which shatters within minutes at ~700°C), specialized laminated or ceramic fire glass uses intumescent interlayers that expand under heat, sealing gaps and blocking flames, smoke, and toxic gases for 60–120 minutes (certified as EI60/EI120). This containment prevents "flashover" scenarios in stairwells—a leading cause of evacuation failures.

Intumescent glazing seals—often overlooked as mere accessories—are in fact the linchpin of fire-resistant glass systems. These specialized components transform passive glazing into active fire barriers by expanding up to 10× their original volume when exposed to heat, sealing critical gaps between glass edges and framing. This dynamic response is fundamental to containing flames, smoke, and toxic gases during building fires. Here, we examine their engineering principles, performance standards, and transformative impact on fire safety.

In the face of a fire, every second counts. Traditional glass shatters within minutes under extreme heat, allowing flames and toxic smoke to spread rapidly. Pronano Fire-Resistant Glass transforms this vulnerability into an impenetrable shield, thanks to its revolutionary imported rigid fire-resistant interlayer—a technological marvel engineered to save lives and property.

Self-closing fire-rated glass doors exemplify passive fire protection engineered for reliability. By autonomously sealing off flames and smoke, syncing with alarm systems, and resisting tampering, they transform ordinary thresholds into life-saving barriers. As high-rise construction surges globally, these systems will remain non-negotiable in fire-resilient architecture.

Fire-rated glass serves as a vital engineered solution for compartmentalizing structures into distinct fire zones. When strategically installed in vertical shafts and critical pathways, these transparent barriers dramatically slow fire progression while maintaining crucial evacuation routes. This systematic approach to fire containment relies on three fundamental principles: integrity (preventing flame passage), insulation (blocking radiant heat), and structural stability (maintaining barrier function under extreme conditions).
