What's involved with fire-rated windows in Stevenage
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
- Fire-stopping to the wall opening
- External-grade fire glass in sealed units
Key checks for Stevenage projects
Matching appearance
Rated windows can usually be finished to match the rest of the elevation.
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.
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.

England regulations that shape the job
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.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.
