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

Insulated Fire Glass (EI) in Dorset: questions
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
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 Dorset?
Yes. We can arrange surveys anywhere in Dorset, including Bournemouth and Poole, Weymouth, Christchurch.
