What's involved with insulated fire glass in Highbury

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.

  • Insulating glass in sealed double-glazed units
  • Internal and external-grade build-ups
  • Impact-classified insulating glass

Key checks for Highbury projects

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.

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.

Fire glazing rules in England

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.
