Insulated Fire Glass (EI): what you get in County Armagh
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.
- Internal and external-grade build-ups
- Handling and installation of heavy panes
- Impact-classified insulating glass
Before you order in County Armagh
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.
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.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
Northern Ireland rules for fire glazing
Northern Ireland Which rules apply?
In Northern Ireland, building work follows the Building Regulations (Northern Ireland) 2012, with fire safety guidance in Technical Booklet E, approved by the district council's building control.
Once in use, the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 require the appropriate person to maintain fire safety measures, including fire-resisting glazing.
Technical Booklet E sets its own provisions for glazing on escape routes, so designs are checked against the Northern Ireland guidance rather than English documents.

FAQs for County Armagh
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.
Can you survey anywhere in County Armagh?
Yes. We can arrange surveys anywhere in County Armagh, including Craigavon and Portadown.
