What double fire doors in County Londonderry should include

Double doors on wards, school corridors and lobbies in County Londonderry take heavy use, so closing sequence and meeting-edge seals get extra attention. Leaf-and-a-half doors are a practical option for County Londonderry care homes and schools that need occasional wide access.
Managing agents, landlords, schools, care providers, businesses and homeowners in County Londonderry can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
Hold-opens and escape
Pairs on corridors are often held open in daily use, with hold-open devices releasing both leaves when the alarm sounds. Where a pair is on an escape route used by the public, the escape hardware and the direction of opening also need to suit the fire strategy.
Fire door law for County Londonderry properties
County Londonderry is in Northern Ireland, where fire doors are covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E on fire safety. Duties in non-domestic premises come from the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010.
The English regulation 10 checking regime does not apply here, so the fire risk assessment sets how often doors in County Londonderry are checked. We hand over evidence that supports it.

Double fire doors questions
Do you provide double fire doors across County Londonderry?
Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
Why does the gap between the two leaves matter?
The meeting edges are where flame and smoke can pass most easily. The gap and the seals there must match the certification for the pair to perform as tested.
Can double fire doors be held open?
Yes, with hold-open devices that release on the fire alarm, or with free-swing closers. Wedges and hooks are not acceptable.
