What's involved with integrity fire glass in Harlow
Integrity fire glass, classified E, stops flames and hot gases passing for the rated time but does not limit the heat coming through. EW glass adds a cap on the heat radiated through the glass. Both are thinner, lighter and cheaper than fully insulated glass.
- Polished wired glass where still appropriate
- EW laminated glass with radiation control
- Modified toughened integrity glass
- Matched beads and seals
Before you order integrity fire glass: what matters
What EW adds
EW glass limits radiation to 15 kW/m² measured one metre from the glass, reducing the risk of igniting materials or harming people nearby.
Impact safety
Modern integrity glass is usually available with an impact classification, unlike plain wired glass.
Cost advantage
Integrity glass costs a fraction of insulated glass and fits slimmer frames, which is why specifying it correctly matters.
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.

Integrity Fire Glass (E & EW): Harlow questions
Is integrity glass allowed on escape routes?
In limited amounts and positions. Building guidance sets the rules; insulating glass is used where those limits are exceeded.
What is the difference between E and EW glass?
EW glass also limits heat radiation through the glass, which reduces the risk to people and materials near it.
Can you price integrity fire glass in Harlow 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 work on occupied buildings in Harlow?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
