What's involved with fire-rated windows in Derby
Most fire-rated windows are fixed lights, because opening windows need the opening sash, hinges and locks to be tested too. We supply and install fixed and, where tested, opening fire-rated windows in steel, aluminium and timber, matched to the surrounding windows where possible.
- Matching sightlines to adjacent non-rated windows
- Fixed fire-rated windows
- External-grade fire glass in sealed units
- Boundary-wall and escape-route windows

Key checks for Derby projects
Boundary distance
The closer a wall is to a boundary, the less unprotected area it can have. Fixed windows that meet the wall's full fire-resistance requirement, including insulation where required, are not counted as unprotected area; integrity-only glazing generally still is.
Retrofits
Replacing a non-rated window near a boundary is often triggered by an extension or change of use. We survey the opening before quoting.
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.

Which rules apply to fire-rated windows in Derby?
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.

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.
Can fire-rated windows open?
Some can, if the opening version has been tested. Fixed fire-rated windows are more common.
Can you price fire-rated windows in Derby from photos?
We can give a guide range from photos and sizes, including a clear photo of any marks on the glass. A fixed price follows a survey.
Do you work on occupied buildings in Derby?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
