Fire-Rated Windows in Westminster: what's included
Fire-rated windows are windows tested as complete units to resist fire, needed where an external wall must protect a neighbouring property, where a window looks onto a protected stair or escape route, or where two parts of a building face each other at close range.
- Tested opening fire-rated windows where available
- External-grade fire glass in sealed units
- Fixed fire-rated windows
- Matching sightlines to adjacent non-rated windows
What to check before ordering fire-rated windows in Westminster
Ventilation
If a fire-rated window cannot open, ventilation may need another route. We coordinate with the designer.
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.
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.
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.
