Insulated Fire Glass (EI) in Blackheath: 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
- EI 30, EI 60, EI 90 and EI 120 glass
- Insulating glass in sealed double-glazed units
- Internal and external-grade build-ups

Before you order insulated fire glass: what matters
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
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.
Which rules apply to insulated fire glass in Blackheath?
England Which rules apply?
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.

FAQs for Blackheath
Can EI glass be used outside?
Only products approved for external use, usually in a sealed unit with UV protection.
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
Can you price insulated fire glass in Blackheath from photos?
We can give a guide range from photos and sizes, including a clear photo of any marks on the glass. A fixed price follows a survey.
Do you work on occupied buildings in Blackheath?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
