Key checks for Crowthorne projects
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
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.
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.

Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.

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.
How quickly can you survey in Crowthorne?
