Does fire-resistant glass fail to meet the required fire-resistance duration? A Guide for Contractors on Quality Control and Integrity Management
Release time：
Nov 11,2025
Construction projects often encounter issues when purchasing fire-resistant glass, such as insufficient fire endurance, cracking under high temperatures, and the lack of 3C certification, leading to failure in fire safety inspections.
Fire-resistant glass relies on its fire rating (GB 15763.1) and laminated structure; Class A offers 1.5 hours of fire resistance, while Class B provides 1 hour.
Key procurement controls: First, verify 3C certification—absolutely avoid selecting products without it. Second, test fire-resistance integrity, ensuring the product remains intact and free from flame penetration for at least 30 minutes under high-temperature conditions. Third, confirm compatibility: choose single-pane fire-resistant glass for partitions, and opt for fire-rated laminated glass for doors and windows.
Suitable scenarios: Choose Class A firewalls, and select Class B for stairwells.
Attention: Installation must be paired with fire-rated profiles and sealant. The manufacturer is required to provide a fire safety inspection report to ensure system compatibility.
