What our insulated fire glass service includes in Warrington
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.
- Matched glazing systems and seals
- EI 30, EI 60, EI 90 and EI 120 glass
- Internal and external-grade build-ups
- Insulating glass in sealed double-glazed units
Key checks for Warrington projects
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.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
