What our insulated fire glass service includes in Purley
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
- Impact-classified insulating glass
- Handling and installation of heavy panes
- Internal and external-grade build-ups
Before you order insulated fire glass: what matters
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.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
