When it comes to protecting lives and property, not all glass is created equal. Fire-rated glass screens are a critical component in passive fire protection — but what exactly do terms like Integrity and Insulation mean? And why should you trust
Clear Divide Glass Partitions for your fire screen solutions?
What Do We Mean by Integrity and Insulation?
In the world of fire-rated glazing,
Integrity (E) and
Insulation (I) are two essential performance measures used to classify how fire-resistant a glass system truly is.
✅ Integrity (E): Containment of Flames and Smoke
This measures how long the glass can withstand fire exposure without allowing flames or hot gases to pass through.
- Prevents the spread of fire from one space to another
- Maintains a physical barrier during a fire
- Remains intact under high temperatures for the specified fire-resistance period
✅ Insulation (I): Heat Transfer Resistance
Insulation takes fire protection a step further. It refers to how long the glass can reduce heat transfer from one side to the other.
- Helps prevent injury from radiant heat
- Protects nearby materials and people on the safe side
- Can be vital in corridors and escape routes
Examples of Fire Ratings
E30 - 30 minutes of integrity – prevents flames/smoke, but not heat.
EI30 - 30 minutes of integrity and insulation – prevents flames and heat transfer.
EI60 - 60 minutes of fire-rated protection (integrity + insulation).
Note: Fire rating requirements should always be confirmed by your local building control authority. Clear Divide does not provide regulatory advice.
