Fanlights, Side Panels & Borrowed Lights: an overview for Gwynedd
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.

Before you order in Gwynedd
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.
Impact safety
Side panels near doors fall in critical locations for impact safety, so the fire glass must also have the right impact classification.
Ventilation grilles
Grilles or openings in fanlights must be fire-rated or removed if the wall is fire-resisting.
Regulations for Gwynedd 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.
Questions from Gwynedd clients
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.
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.
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.
Do you cover all of Gwynedd?
Yes. We take enquiries from across Gwynedd, including Bangor and Caernarfon, Holyhead, Pwllheli, Llangefni, and arrange surveys to suit your programme.
