Fire-Rated Windows: an overview for Mid Glamorgan
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.
- External-grade fire glass in sealed units
- Fire-stopping to the wall opening
- Fixed fire-rated windows
Before you order in Mid Glamorgan
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.
Ventilation
If a fire-rated window cannot open, ventilation may need another route. We coordinate with the designer.

Regulations for Mid Glamorgan projects
Wales Which rules apply?
Building regulations are devolved in Wales, so fire safety design follows the Welsh Ministers' version of Approved Document B rather than the English one, alongside impact safety guidance for glazing.
The Regulatory Reform (Fire Safety) Order 2005 applies in Wales, so the responsible person must maintain fire-resisting glazing as part of the premises' fire safety measures. The Fire Safety Act 2021 confirmed this extends to the structure, external walls and flat entrance doors of multi-occupied residential buildings.
FAQs for Mid Glamorgan
Can fire-rated windows open?

Do fire-rated windows look different?
Frames can be slightly heavier, but most can be finished to match surrounding windows.
