Fire-Rated Windows in March: what's included
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.
- Boundary-wall and escape-route windows
- Fixed fire-rated windows
- External-grade fire glass in sealed units
- Matching sightlines to adjacent non-rated windows
How we work in March
England rules applied
Designs follow the building and fire safety rules that apply in England, not a one-size-fits-all approach.
Evidence you can file
You receive the classification references, glass marks and installation photographs for your fire safety records.
Honest about unknowns
If an existing frame in a March building has no traceable evidence, we say so and price the options rather than guess.
Before you order fire-rated windows: what matters
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.
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.
