What our insulated fire glass service includes in Renfrew
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.
- EI 30, EI 60, EI 90 and EI 120 glass
- Internal and external-grade build-ups
- Matched glazing systems and seals
- Insulating glass in sealed double-glazed units
Before you order insulated fire glass: what matters
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.
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.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
Fire glazing rules 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 about insulated fire glass in Renfrew
Can EI glass be used outside?
Only products approved for external use, usually in a sealed unit with UV protection.
Why is insulated fire glass so much more expensive?
It is a multi-layer product with specialist interlayers, and the frame and installation must suit its weight.
How quickly can you survey in Renfrew?
Survey timing in Renfrew depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
Do you work on occupied buildings in Renfrew?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
