When selecting safety glass for buildings, two common options are security laminated glass and tempered glass. While both improve safety, they offer different advantages.
Verre trempé
Tempered glass is heat-treated to increase strength. It is 4–5 times stronger than regular glass and breaks into small, blunt pieces.
Advantages:
- High strength
- Thermal resistance
- Safety break pattern
However, tempered glass shatters completely when broken, which may leave openings in the building envelope.
Security Laminated Glass
Security laminated glass consists of multiple glass layers bonded with strong interlayers.
Advantages include:
- Resistance to forced entry
- Glass remains in place after impact
- Higher security performance
- Better sound insulation
Best Choice for Security
For buildings where security and intrusion resistance are critical, laminated glass is typically the better option.
Many projects even combine tempered glass with laminated construction to achieve both strength and security.
