What our insulated fire glass service includes in Rutland
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.
- Handling and installation of heavy panes
- Insulating glass in sealed double-glazed units
- Internal and external-grade build-ups
Before you order in Rutland
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.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Places we cover in Rutland
