What's involved with fire-rated windows in Windsor
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.
- External-grade fire glass in sealed units
- Boundary-wall and escape-route windows
- Matching sightlines to adjacent non-rated windows
- Tested opening fire-rated windows where available
Before you order fire-rated windows: what matters
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.
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.
Which rules apply to fire-rated windows in Windsor?
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.

Fixed written quotes
After survey you get a fixed written quote for the agreed scope, so Windsor budgets are not open-ended.

FAQs for Windsor
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 Windsor 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 Windsor?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
