Key checks for Bushey projects
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
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.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Bushey coverage and nearby towns
Survey visits can be arranged anywhere in Bushey, including the WD23, WD17, WD18, WD19, WD24, WD25 districts, and in nearby Watford, Borehamwood, Harrow. Bushey is about 3 km from Watford, the largest town in our Hertfordshire coverage.

Insulated Fire Glass (EI): Bushey questions
Can EI glass be used outside?
Only products approved for external use, usually in a sealed unit with UV protection.
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 carry out insulated fire glass in Bushey?
Yes. We survey and install in Bushey and across Hertfordshire, including the WD23 district and nearby Watford.
Do you work on occupied buildings in Bushey?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
