Fire-Rated Windows: an overview for Cornwall
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
- Matching sightlines to adjacent non-rated windows
- External-grade fire glass in sealed units
Before you order in Cornwall
Ventilation
If a fire-rated window cannot open, ventilation may need another route. We coordinate with the designer.
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.

FAQs for Cornwall
Can fire-rated windows open?
Some can, if the opening version has been tested. Fixed fire-rated windows are more common.
When do I need a fire-rated window?
Usually when a wall is close to a boundary, when a window overlooks a protected escape route, or when part of a building faces another part at close range. Your designer or building control will confirm.
Do fire-rated windows look different?
Frames can be slightly heavier, but most can be finished to match surrounding windows.
