What's involved with fire-rated windows in Derry / Londonderry
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.
- Fire-stopping to the wall opening
- External-grade fire glass in sealed units
- Tested opening fire-rated windows where available
- Boundary-wall and escape-route windows
What to check before ordering fire-rated windows in Derry / Londonderry
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.
Matching appearance
Rated windows can usually be finished to match the rest of the elevation.
Which rules apply to fire-rated windows in Derry / Londonderry?
Northern Ireland Which rules apply?
In Northern Ireland, building work follows the Building Regulations (Northern Ireland) 2012, with fire safety guidance in Technical Booklet E, approved by the district council's building control.
Once in use, the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 require the appropriate person to maintain fire safety measures, including fire-resisting glazing.
Technical Booklet E sets its own provisions for glazing on escape routes, so designs are checked against the Northern Ireland guidance rather than English documents.
