Fanlights, Side Panels & Borrowed Lights: an overview for Dorset
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 Dorset
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.
England rules for fire glazing
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.
Fanlights, Side Panels & Borrowed Lights in Dorset: questions
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.
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.
Which parts of Dorset do you cover?
