Fire-Rated Windows in Potters Bar: 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.
- Fixed fire-rated windows
- External-grade fire glass in sealed units
- Matching sightlines to adjacent non-rated windows
- Boundary-wall and escape-route windows
Key checks for Potters Bar projects
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.
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.
