Fire-Rated Glass: The Vital Fire Barrier

Fire-rated glass is a critical building safety component that effectively blocks fire and smoke while maintaining visibility.

Core Technology:

• Composite Type: Multiple glass layers with transparent intumescent interlayers that expand into an insulating barrier when exposed to heat

• Monolithic Type: Chemically strengthened glass (e.g., cesium-potassium) with exceptional thermal shock resistance

Key Performance:

• Fire Integrity: Maintains integrity for 30-180 minutes in standard tests, preventing flame and smoke spread

• Heat Insulation: Keeps the non-fire side temperature significantly below safety limits

• High Strength: 6-8 times stronger than regular glass

• Excellent Light Transmission: Provides natural lighting while ensuring safety

Main Applications:

• Commercial Buildings: Fire partitions in shopping malls, observation windows in escape routes

• Healthcare Facilities: Observation windows in hospital operating rooms and ICUs

• Transportation Hubs: Fire barriers in subway stations and airport terminals

• Industrial Plants: Control room windows in power plants and chemical facilities

Standards & Certification:
Products must pass national standard testing, with key parameters including:

• Fire resistance duration (30/60/90/120 minutes)

• Maximum temperature rise on the non-fire side (≤140°C)

• Light transmittance (≥75%)

Fire-rated glass serves as an invisible but critical barrier, successfully balancing architectural aesthetics with life safety requirements in modern construction. Through continuous technological advancement, it provides reliable protection while meeting design needs.
