Fanlights, Side Panels & Borrowed Lights: an overview for West Glamorgan
Fanlights, side panels and borrowed lights are the glazed panels above and beside doors, or set into internal walls to share daylight between rooms. Where the wall or door around them is fire-resisting, the glazing must be fire-rated too, or it becomes the weak point.

Flat entrance doors
In blocks of flats, the glazing around flat entrance doors forms part of the protection of the common parts and needs to match the door's performance.

Regulations for West 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.
Wales is introducing its own building safety regime for occupied residential buildings, so check current Welsh requirements before planning major works to blocks of flats.
FAQs for West Glamorgan
Does the glass above a fire door need to be fire-rated?
If the wall or door assembly is fire-resisting, yes. Ordinary glass above or beside a fire door creates a weak point.
What is a borrowed light?
An internal window that shares daylight between rooms or with a corridor. In a fire-resisting wall it must be fire-rated.
Do side panels need safety glass too?
Yes. Glass within 300mm of a door edge and below 1500mm is a critical location for impact safety.
