Insulated Fire Glass (EI): what you get in Dunbartonshire
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

What to check before ordering in Dunbartonshire
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
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.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
Which rules apply in Scotland?
Scotland Which rules apply?
In Scotland, building work needs a building warrant under the Building (Scotland) Regulations 2004, with fire guidance in Section 2 of the Building Standards Technical Handbooks rather than Approved Documents.
For relevant premises, the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006 place duties on the duty holder to maintain fire safety measures, which include fire-resisting glazing.
Scottish guidance has its own approach to escape routes and compartmentation, so glazing designs are checked against the Technical Handbooks and the warrant drawings.
Questions from Dunbartonshire clients
What does EI 60 mean?
The glazing system kept fire on one side (integrity) and limited the temperature rise on the other side (insulation) for at least 60 minutes in a standard fire test.
Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
Do you cover all of Dunbartonshire?
Yes. We take enquiries from across Dunbartonshire, including Bearsden and Clydebank, Vale of Leven, Bishopbriggs, and arrange surveys to suit your programme.
