Fanlights, Side Panels & Borrowed Lights: what you get in County Down
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.
- Glass, beads and seals to the frame evidence
- Complete replacement frames where needed
- Fire-rated fanlights above fire doors
Key checks for County Down projects
Borrowed lights
Internal windows between rooms and corridors are a frequent survey finding in older offices and schools.
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.
Upgrade or replace?
If the existing frame can be shown to be suitable, new glass and seals may be enough; otherwise a complete rated frame is the reliable answer.

Fanlights, Side Panels & Borrowed Lights in County Down: questions
Can you just replace the glass?
Sometimes, if the existing frame is suitable. We check the frame before recommending glass-only replacement.
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.
Do you cover all of County Down?
Yes. We take enquiries from across County Down, including Bangor and Newtownards, Newry, and arrange surveys to suit your programme.
