What's involved with integrity fire glass in Hounslow
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
- EW laminated glass with radiation control
- Impact-classified integrity options
- Matched beads and seals

Key checks for Hounslow projects
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.
Limits on escape routes
Building guidance restricts how much integrity-only glass can be used on protected escape routes and where it can sit. Check the route before choosing E glass.
Not insulating
E glass gets hot in a fire. Furniture or stored materials beside it can ignite from radiated heat.

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 Hounslow
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.
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.
How quickly can you survey in Hounslow?
Survey timing in Hounslow depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
Do you work on occupied buildings in Hounslow?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
