Is thicker tempered glass safer? What's the key?
Many people believe that thicker tempered glass is safer, but in reality, thickness is not the only safety standard. The key also depends on the tempering process, stress distribution, and application scenarios. Here are the core points to note when purchasing:
1. Misconception: The thicker the tempered glass, the stronger the impact resistance
Truth: The impact resistance of glass depends not only on its thickness but also on the quality of tempering and the uniformity of stress. If the tempering process is not up to standard, even thick glass may easily break due to uneven stress.
2. Misconception: All tempered glass is explosion-proof and shatter-proof
Truth: The safety of tempered glass comes from the pre-stressed layer under uniform stress, but if the tempering process is not in place, even thick glass may spontaneously explode due to localized stress concentration. High-quality tempered glass should undergo heat soak testing (HST) to reduce the risk of spontaneous explosion.
3. Misconception: Thicker glass is suitable for all scenarios
Truth: Glass thickness should be selected according to the actual Applications. For example:
- Indoor doors and windows: 5mm~8mm tempered glass is sufficient;
- Glass curtain walls: 10mm or more is required, and laminated processing should be considered to enhance safety;
- Skylights/high-rise glass: It is recommended to use laminated tempered glass, which can adhere to the interlayer even if it breaks, preventing it from falling and injuring people.
Suggestions to avoid pitfalls:
- Check the tempering quality of the glass to ensure that the surface is free of obvious ripples, bubbles, and other defects.
- Choose tempered glass that has undergone heat soak testing (HST) to reduce the risk of spontaneous explosion.
- Choose the appropriate thickness according to the application scenario and consider laminated glass to improve safety.
Conclusion: Thickness is not the only standard for measuring safety; tempering quality, stress uniformity, heat soak testing, and application scenarios are the key!
