Insulated Fire Glass (EI)
EI 30 to EI 120 glass that blocks heat as well as flames.
Learn more →For Feltham buildings, we supply, replace and check fire-resistant glass wherever the fire strategy depends on it, working to the tested system rather than the glass alone.

Fire-resistant glass is glazing that has been tested, as part of a complete glazed system, to hold back fire for a set time. It is classified by what it stops: E (integrity) keeps flames and hot gases on the fire side, EW also limits the heat radiated through the glass, and EI (integrity and insulation) also limits the temperature rise on the protected side, so people can pass it more safely.
Many insulating fire glasses use interlayers that need protecting from UV and moisture, so external positions need a product approved for exterior use, with the right edge seal and glazing system.
The fire strategy or building control drawings set the rating for each element. Integrity-only glass is cheaper and thinner, but its use on escape routes is restricted; insulating glass carries far fewer restrictions because people can pass it safely during a fire.
Insulating fire glass gets thicker and heavier as the rating rises. Large EI 60 and EI 120 panes often need lifting equipment and a frame designed for the load, which we plan before the delivery date.
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
Our Greater London coverage takes in Feltham (TW13, TW14, TW15, TW6, TW5, TW3) and the neighbouring towns of Hanworth, Ashford, Hounslow. Feltham is one of the Greater London districts we cover.
Designs follow the building and fire safety rules that apply in England, not a one-size-fits-all approach.
You receive the classification references, glass marks and installation photographs for your fire safety records.
We can phase work in Feltham around residents, staff or pupils, with out-of-hours options.
Sector guides below cover blocks of flats, public buildings and other buildings in Feltham.
E is integrity only: it stops flames and hot gases passing for the rated time. EW adds a limit on radiated heat through the glass. EI adds insulation, keeping the unexposed face below set temperature rises so people can pass it safely. The number after the letters is the time in minutes.
Integrity glass can be similar in thickness to standard glass. Insulating glass is laminated from several layers, so it gets markedly thicker and heavier as the rating increases from EI 30 to EI 120.
Building work in Feltham follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.

We visit Feltham to measure, record existing marks and check the frames and substrate.
You receive a written quote naming the tested system and classification.
We install, photograph seals and fixings before closing up, and hand over the schedule.
Send sizes, photos of any glass marks or your inspection report and we will come back with the right tested system.
