Tempered glass is a highly durable, treated material often chosen for safety, as it crumbles into blunt fragments upon breakage. Commonly applied in vehicles, shower enclosures, and glass furniture, it’s ideal in areas where human safety is prioritized due to its reduced injury risk.
How Tempered Glass Works
The tempering process involves heating glass to extreme temperatures before cooling it rapidly, creating tension within and compressing its outer layers. This increases its durability four to five times over standard glass. Although stronger, it remains vulnerable to intentional impact, shattering in a safer, predictable manner upon breakage.
Why Tempered Glass is Not Suitable for Security Applications
While tougher than annealed glass, tempered glass is unsuitable for security purposes because it’s designed to break safely rather than withstand force. Security-focused locations, such as retail storefronts or entryways, should avoid tempered glass due to its limited resistance to intrusion.
Recommended Alternatives to Tempered Glass for Enhanced Security
- Security Window Film: Applied to glass, it holds broken shards in place, slowing entry attempts and minimizing hazards from flying fragments.
- Polycarbonate Security Glazing: Offering near-unbreakable strength, this is a superior option for locations prone to break-ins or extreme weather.
When to Use Tempered Glass
Tempered glass excels for interior applications, like office partitions or non-load-bearing walls. It’s valuable for ensuring safety where potential breakage doesn’t compromise security but mitigates injury risks.
Conclusion
Tempered glass is a versatile, safety-oriented solution but lacks security resilience. For comprehensive protection, consider security film or polycarbonate glazing where necessary.
