Key checks for Hertford projects
Impact safety
Modern integrity glass is usually available with an impact classification, unlike plain wired glass.
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.
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.
Which rules apply to integrity fire glass in Hertford?
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.
