Key checks for Clwyd projects
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
Wales rules for fire glazing
Wales Which rules apply?
Building regulations are devolved in Wales, so fire safety design follows the Welsh Ministers' version of Approved Document B rather than the English one, alongside impact safety guidance for glazing.
The Regulatory Reform (Fire Safety) Order 2005 applies in Wales, so the responsible person must maintain fire-resisting glazing as part of the premises' fire safety measures. The Fire Safety Act 2021 confirmed this extends to the structure, external walls and flat entrance doors of multi-occupied residential buildings.
Questions from Clwyd clients
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.
What does EI 60 mean?
The glazing system kept fire on one side (integrity) and limited the temperature rise on the other side (insulation) for at least 60 minutes in a standard fire test.
Do you cover all of Clwyd?
