What's involved with insulated fire glass in March
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.
- EI 30, EI 60, EI 90 and EI 120 glass
- Insulating glass in sealed double-glazed units
- Matched glazing systems and seals
- Handling and installation of heavy panes
Key checks for March projects
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
