What to check before ordering in Wiltshire

Fanlights and side panels can be missed when fire doors are upgraded, leaving ordinary glass beside a new fire door.
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.
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.
Fanlights, Side Panels & Borrowed Lights in Wiltshire: questions
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.
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.
Do you cover all of Wiltshire?
Yes. We take enquiries from across Wiltshire, including Swindon and Salisbury, Trowbridge, Chippenham, and arrange surveys to suit your programme.
