What our insulated fire glass service includes in Seaford
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
- EI 30, EI 60, EI 90 and EI 120 glass
- Impact-classified insulating glass
- Matched glazing systems and seals

Before you order insulated fire glass: what matters
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.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.

FAQs for Seaford
Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.
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.
Do you carry out insulated fire glass in Seaford?
Yes. We survey and install in Seaford and across East Sussex, including the BN25 district and nearby Eastbourne.
How quickly can you survey in Seaford?
Survey timing in Seaford depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
