What our fire-resistant glass service includes in Gainsborough
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.
- Impact-classified build-ups for critical locations
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Intumescent glazing seals, tapes and gaskets to the tested specification
- Insulating (EI) intumescent-interlayer and gel-filled glass
Before you order fire-resistant glass: what matters
Can any fire glass go in any fire-rated frame?
No. A frame is only rated with the glass types and pane sizes it was tested or assessed with. We check the frame's evidence before quoting, and if the existing frame is unknown we say so and price the options.
Marking and records
Most fire glass is permanently marked with its product and classification. We record the marks, pane sizes and evidence references on handover so whoever is responsible for fire safety can show what is installed.
Weight and handling
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.

England regulations that shape the job
England Which rules apply?
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.

Fire-Resistant Glass: Gainsborough questions
What is the difference between E, EW and EI fire glass?
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.
How thick is fire-resistant glass?
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.
Can you price fire-resistant glass in Gainsborough from photos?
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.
Do you carry out fire-resistant glass in Gainsborough?
Yes. We survey and install in Gainsborough and across Lincolnshire, including the DN21 district and nearby Retford.
