Integrity Fire Glass (E & EW) in Portsmouth: what's included
We supply and fit integrity glass in screens, doors, vision panels and windows where the fire strategy allows it, and upgrade to EW or EI where it does not. Choosing correctly between E, EW and EI is where most of the cost on a project is decided.
- Modified toughened integrity glass
- EW laminated glass with radiation control
- Matched beads and seals
- Polished wired glass where still appropriate
What to check before ordering integrity fire glass in Portsmouth
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.
Cost advantage
Integrity glass costs a fraction of insulated glass and fits slimmer frames, which is why specifying it correctly matters.
Where integrity glass fits
Integrity-only glass may be acceptable in some fire-resisting partitions, screens and doors, often at high level, within the limits national guidance sets. Compartment walls normally need insulating (EI) glazing.
Which rules apply to integrity fire glass in Portsmouth?
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.
