- Handling and installation of heavy panes
- EI 30, EI 60, EI 90 and EI 120 glass
- Insulating glass in sealed double-glazed units
- Impact-classified insulating glass
Before you order insulated fire glass: what matters
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
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.
