Fire-Resistant Glass in Market Harborough: what's included
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.
- Integrity with radiation control (EW) laminated glass
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Intumescent glazing seals, tapes and gaskets to the tested specification
- Glazing beads and fixings to the frame manufacturer's details
What to check before ordering fire-resistant glass in Market Harborough
Inside or outside?
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.
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.
Impact safety still applies
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.
Fire glazing rules in England
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.
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.

Fire-Resistant Glass: Market Harborough 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.
Is toughened glass fire-resistant?
Ordinary toughened safety glass is not. It can shatter early in a fire. Fire-resistant integrity glass is specially processed or formulated and only gains a rating when fitted in a tested frame and glazing system.
Can you price fire-resistant glass in Market Harborough 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 Market Harborough?
Yes. We survey and install in Market Harborough and across Leicestershire, including the LE16 district and nearby Corby.
