What our insulated fire glass service includes in Thamesmead
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
- Insulating glass in sealed double-glazed units
- Impact-classified insulating glass
- Handling and installation of heavy panes
How we work in Thamesmead

Every quote in Thamesmead identifies the tested system: frame, glass, beads, seals and fixings, within its pane-size limits.

Honest about unknowns
If an existing frame in a Thamesmead building has no traceable evidence, we say so and price the options rather than guess.
Key checks for Thamesmead projects
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
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.
