How to identify fire-rated glass grades? How to meet safety standards?
1. Understanding fire-rated glass grades (classified by fire resistance time)
- C-class (heat-insulating type)🔥🔥🔥: High temperature resistance + heat insulation + smoke blocking, commonly used in Class A fire doors and partitions.
- B-class (partially heat-insulating type)🔥🔥: Can block flames and high-temperature radiation, suitable for fire windows and curtain walls.
- A-class (non-heat-insulating type)🔥: Only fire-resistant, not heat-insulating, suitable for fire doors and windows, and escape routes.
2. How to identify the quality of fire-rated glass when purchasing?
Check for national certification: Must comply with GB 15763.1-2009《Building safety glass fire-rated glass》standard.
Check the test report: Ensure that it has passed fire resistance tests and impact resistance tests, and that a formal manufacturer has issued a test report.
Observe the glass edges & interlayer: High-quality fire-rated glass has flat edges, no bubbles, and a uniform interlayer.
3. How to choose the right fire-rated glass?
- Ordinary building use → A-class non-heat-insulating type, fire-resistant but not heat-insulating, high cost-effectiveness.
- High-security fire doors and windows → B-class partially heat-insulating type, fire-resistant + radiation blocking.
- Key fire partitions → C-class heat-insulating type, triple protection, highest safety level.
Purchase suggestions:
Check certification (national standard GB 15763.1), choose qualified manufacturers.
Check needs (fire-resistant or heat-insulating + fire-resistant), choose the right level.
Check the test report to ensure real fire resistance performance.
