E 30 to EI 60
Fire-Rated Windows
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.

What does our fire-rated windows service include?
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.
- Fixed fire-rated windows
- Tested opening fire-rated windows where available
- External-grade fire glass in sealed units
- Boundary-wall and escape-route windows
- Matching sightlines to adjacent non-rated windows
- Fire-stopping to the wall opening
What should you check before ordering?
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.
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.
Ventilation
If a fire-rated window cannot open, ventilation may need another route. We coordinate with the designer.
Matching appearance
Rated windows can usually be finished to match the rest of the elevation.
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.
What evidence do you get?
- Window test or assessment reference
- External glass unit specification
- Opening and fixing details
- Installer's completion record

Frequently asked questions
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.
Is fire-rated glass in a standard window enough?
No. The frame, glazing system and fixings also need to be part of a tested window.
Do fire-rated windows look different?
Frames can be slightly heavier, but most can be finished to match surrounding windows.
