What to check before ordering in County Londonderry
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.

Questions from County Londonderry clients
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
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.

Yes. We take enquiries from across County Londonderry, including Derry / Londonderry and Coleraine, and arrange surveys to suit your programme.
