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.

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.

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).

Fire-resistant glass, a vital safety component in numerous applications, demands meticulous handling during packaging and shipping to ensure its integrity and prevent damage.

Building professionals well appreciate the essential nature of glass in today's architecture. It's ability to allow natural illumination, define space, give visual transparency and satisfy aesthetics while combining multi-funtional qualities and comforts such as safety, security, energy efficiency and solar control.
