What our fire-rated fanlights and side panels service includes in Windsor

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.

  • Borrowed lights in fire-resisting walls
  • Glass, beads and seals to the frame evidence
  • Records for your fire safety file
  • Complete replacement frames where needed

Key checks for Windsor projects

Impact safety

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

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.

Fire glazing rules in England

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.

Sectors we cover in Windsor

We can survey and quote for industrial units, blocks of flats and other building types in Windsor.
