Insulated Fire Glass (EI): an overview for Warwickshire

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
  • Matched glazing systems and seals
  • Handling and installation of heavy panes

Key checks for Warwickshire 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.

Optical quality

Modern EI glass is clear in normal use, with high light transmission at lower ratings.

Storage on site

Insulating fire glass should be stored dry, upright and away from direct sun before fitting.

England rules for fire glazing

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.
