Insulated Fire Glass (EI)
EI 30 to EI 120 glass that blocks heat as well as flames.
Learn more →From the GL5 district outwards, we arrange fire-resistant glass for buildings across Stroud, matching glass, frames and seals to tested evidence rather than guesswork.

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.
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.
Glass in doors, side panels and low-level positions has to meet impact safety rules as well as the fire rating. Most modern fire glass carries an impact classification; old wired glass usually does not.
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.
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.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.
Survey visits can be arranged anywhere in Stroud, including the GL5, GL6 districts, and in nearby Gloucester, Cirencester, Cheltenham. Gloucester, around 13 km from Stroud, is the largest town in the same coverage area.
You receive the classification references, glass marks and installation photographs for your fire safety records.
If an existing frame in a Stroud building has no traceable evidence, we say so and price the options rather than guess.
We can phase work in Stroud around residents, staff or pupils, with out-of-hours options.
We can survey and quote for public buildings, blocks of flats and other building types in Stroud.
Often, yes. We read the marks on the existing panes and check them against the frame evidence. Where the original product is discontinued we look for an alternative covered by the same evidence or a formal assessment.
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.
Yes. We survey and install in Stroud and across Gloucestershire, including the GL5 district and nearby Gloucester.
We can give a guide range from photos and sizes, including a clear photo of any marks on the glass. A fixed price follows a survey.

A survey in Stroud confirms sizes, access, existing evidence and fixing conditions.
Your quote lists each item with its classification and the evidence it relies on.
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.
