What's involved with fire-rated windows in Barnet
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
- Fire-stopping to the wall opening
- Tested opening fire-rated windows where available
- Boundary-wall and escape-route windows

Key checks for Barnet projects
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.
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.
Ventilation
If a fire-rated window cannot open, ventilation may need another route. We coordinate with the designer.
Which rules apply to fire-rated windows in Barnet?
England Which rules apply?
