What our insulated fire glass service includes in Hatfield
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
- Handling and installation of heavy panes
- Impact-classified insulating glass
- Internal and external-grade build-ups
What to check before ordering insulated fire glass in Hatfield
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
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.
