Short answer. E60 means the glass keeps flames and hot gases out for 60 minutes. EI60 means it does that and also limits how hot the far side gets for 60 minutes. EI60 is the stricter class.
The letter shows what the glass is tested to hold back. The number is the time in minutes.
E is integrity: no flames or hot gases pass through.
I is insulation: the temperature rise on the unexposed side stays within set limits.
60 is the duration in minutes.
E60 | EI60 | |
|---|---|---|
Stops flames and hot gases | Yes, 60 minutes | Yes, 60 minutes |
Limits heat on the far side | No | Yes, 60 minutes |
Far side can be touched safely | Not guaranteed | Surface temperature rise is limited |
Typical use | Where people will not be close to the glass, or with other protection | Escape routes, corridors and stairwells where people pass close to the glass |
E60 is common where the glass is a barrier but nobody is close to it during a fire. EI60 is usually required where people may pass close to the glass, such as escape corridors and stairwells. The requirement comes from your building code and the rating of the wall or door, so confirm it with the authority having jurisdiction.
State the rating (E or EI) and the duration, the standard, the glass size, and the frame or fixing system. A rated glass only counts when the frame, seals and fixings are part of the tested assembly.
See our single-layer E-class glass and EI-class glass, and send your requirements for a written confirmation of the specification.
Results relate to the tested specimen/assembly only; the specification of each order is confirmed in writing.
