Insulated Fire Glass (EI): an overview for Suffolk
Insulated fire glass, classified EI, is glazing that maintains integrity and keeps the temperature rise on the non-fire side within set limits for the rated time. It is usually made of several glass panes bonded with interlayers that foam into an insulating barrier when heated, or with a clear gel that absorbs heat.

- EI 30, EI 60, EI 90 and EI 120 glass

What to check before ordering in Suffolk
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
Thickness and weight
Each step up in rating adds layers, so EI 120 is far thicker and heavier than EI 30. The frame has to be designed for it.
The temperature rule
EI testing limits the average temperature rise on the unexposed face to 140°C and any single point to 180°C, which is why people can pass it.
