Insulated Fire Glass (EI) in Mitcham: what's included
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
- Impact-classified insulating glass
- Handling and installation of heavy panes
- EI 30, EI 60, EI 90 and EI 120 glass
Before you order insulated fire glass: what matters
Thickness and weight
Each step up in rating adds layers, so EI 120 is far thicker and heavier than EI 30. The frame has to be designed for it.
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.
