Insulated Fire Glass (EI) in Finchley: what's included
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.
- Insulating glass in sealed double-glazed units
- Matched glazing systems and seals
- Internal and external-grade build-ups
- Impact-classified insulating glass

Key checks for Finchley projects
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
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.
