What our fire-rated windows service includes in Welwyn Garden City
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.
- Fixed fire-rated windows
- Boundary-wall and escape-route windows
- Matching sightlines to adjacent non-rated windows
- External-grade fire glass in sealed units
What to check before ordering fire-rated windows in Welwyn Garden City
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.
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.
