Toughened vs Laminated Glass: What's the Difference?

Toughened and laminated glass are both safety glass products — but they behave very differently when they break, and the rules about which one is required in which location are specific. Here is what you need to know.

What This Guide Covers

• Toughened glass breaks into small, blunt pieces — safer for doors and low-level glazing
• Laminated glass holds together when broken — required for overhead glazing and walk-on floors
• Building Regulations require safety glass in critical locations (within 800mm of floor or door)
• Laminated glass provides better acoustic insulation — popular in London's busiest streets
• Structural applications (balustrades, walk-on floors) always require laminated glass
