What's involved with integrity fire glass in Chesham
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.
- Glass-ceramic and borosilicate integrity glass
- Modified toughened integrity glass
- Polished wired glass where still appropriate
- EW laminated glass with radiation control
Key checks for Chesham projects
Not insulating
E glass gets hot in a fire. Furniture or stored materials beside it can ignite from radiated heat.
Cost advantage
Integrity glass costs a fraction of insulated glass and fits slimmer frames, which is why specifying it correctly 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.
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.
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.

FAQs for Chesham
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.
Do you work on occupied buildings in Chesham?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
Do you carry out integrity fire glass in Chesham?
Yes. We survey and install in Chesham and across Buckinghamshire, including the HP5 district and nearby Amersham.
