Before you order fire-rated windows: what matters
Escape windows are different
Windows used for escape from rooms have their own size and opening rules, and should not be confused with fire-resisting windows.
Why fixed lights are common
An opening sash introduces gaps and hardware that all need testing. Fixed fire-rated windows are simpler and more widely available.
Matching appearance
Rated windows can usually be finished to match the rest of the elevation.
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.

Questions about fire-rated windows in Hertford
When do I need a fire-rated window?
Usually when a wall is close to a boundary, when a window overlooks a protected escape route, or when part of a building faces another part at close range. Your designer or building control will confirm.
Do fire-rated windows look different?
Frames can be slightly heavier, but most can be finished to match surrounding windows.
How quickly can you survey in Hertford?
Survey timing in Hertford 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 Hertford?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
