Key checks for County Londonderry 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.

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.

Northern Ireland rules for fire glazing

Northern Ireland Which rules apply?

In Northern Ireland, building work follows the Building Regulations (Northern Ireland) 2012, with fire safety guidance in Technical Booklet E, approved by the district council's building control.

Once in use, the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 require the appropriate person to maintain fire safety measures, including fire-resisting glazing.

Questions from County Londonderry 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.

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.

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 County Londonderry do you cover?

All of it: Derry / Londonderry, Coleraine and every district in the BT postcode areas.
