What's involved with insulated fire glass in Northolt

- Matched glazing systems and seals
- Internal and external-grade build-ups
- EI 30, EI 60, EI 90 and EI 120 glass

Key checks for Northolt projects
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.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
