Insulated Fire Glass (EI): what you get in Bedfordshire
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.
- Impact-classified insulating glass
- Internal and external-grade build-ups
- EI 30, EI 60, EI 90 and EI 120 glass
Before you order in Bedfordshire
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
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.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.

Questions from Bedfordshire clients
Why is insulated fire glass so much more expensive?
It is a multi-layer product with specialist interlayers, and the frame and installation must suit its weight.
What does EI 60 mean?
The glazing system kept fire on one side (integrity) and limited the temperature rise on the other side (insulation) for at least 60 minutes in a standard fire test.
Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.
Do you cover all of Bedfordshire?
Yes. We take enquiries from across Bedfordshire, including Luton and Bedford, Dunstable, Leighton Buzzard, Ampthill, and arrange surveys to suit your programme.
