Fanlights, Side Panels & Borrowed Lights: what you get in Hertfordshire
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.

Key checks for Hertfordshire projects
Borrowed lights
Internal windows between rooms and corridors are a frequent survey finding in older offices and schools.
Ventilation grilles
Grilles or openings in fanlights must be fire-rated or removed if the wall is fire-resisting.
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.

FAQs for Hertfordshire
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.
