Fanlights, Side Panels & Borrowed Lights

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.

What does our fire-rated fanlights and side panels service include?

These panels are common in flat entrance doors, communal corridors, schools and older buildings, and they are often found glazed with ordinary glass. We survey them, replace unsuitable glass, correct beads and seals, and supply complete rated frames where the existing frame cannot be upgraded.

  • Fire-rated fanlights above fire doors
  • Glazed side panels beside fire doors
  • Borrowed lights in fire-resisting walls
  • Glass, beads and seals to the frame evidence
  • Complete replacement frames where needed
  • Records for your fire safety file

What should you check before ordering?

Often overlooked

Fanlights and side panels can be missed when fire doors are upgraded, leaving ordinary glass beside a new fire door.

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.

Impact safety

Side panels near doors fall in critical locations for impact safety, so the fire glass must also have the right impact classification.

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.

What evidence do you get?

  • Glass type and marks recorded
  • Frame assessment or replacement frame evidence
  • Before and after photographs
  • Completion schedule

Frequently asked questions

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.

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.
