Fire-Rated Windows in Sudbury: what's included
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
- Boundary-wall and escape-route windows
- Tested opening fire-rated windows where available
- Matching sightlines to adjacent non-rated windows
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.
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.
Ventilation
If a fire-rated window cannot open, ventilation may need another route. We coordinate with the designer.

Fire glazing rules in England
England Which rules apply?
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
Sudbury building types
We can survey and quote for blocks of flats, public buildings and other building types in Sudbury.
Questions about fire-rated windows in Sudbury
Do fire-rated windows look different?
Frames can be slightly heavier, but most can be finished to match surrounding windows.
Can fire-rated windows open?
Some can, if the opening version has been tested. Fixed fire-rated windows are more common.
Do you work on occupied buildings in Sudbury?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
How quickly can you survey in Sudbury?
Survey timing in Sudbury depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
