Fanlights, Side Panels & Borrowed Lights: what you get in Berkshire
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.
- Glazed side panels beside fire doors
- Borrowed lights in fire-resisting walls
- Glass, beads and seals to the frame evidence
Before you order in Berkshire
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.
Ventilation grilles
Grilles or openings in fanlights must be fire-rated or removed if the wall is fire-resisting.
Often overlooked
Fanlights and side panels can be missed when fire doors are upgraded, leaving ordinary glass beside a new fire door.

Questions from Berkshire clients
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.
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.
Which parts of Berkshire do you cover?
