Glazed fire doors in Derry: what's involved
Our glazed fire doors service covers Derry and the wider County Londonderry area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
In and around Derry, fire door work covers everything from care homes to houses with integral garages. We plan each job around the people who use the building.
We check glazed doors in Derry for both fire performance and safety glazing before recommending repair or replacement. Schools, offices and care settings in Derry often need vision panels, and each one has to use fire-rated glass in a tested system.
Why glazing is a common failure point
Vision panels are useful on corridors, classrooms and wards, but they are also where many fire doors go wrong. Ordinary glass gets swapped in after a breakage, beads are fixed with the wrong pins, glazing seals are missing, or an aperture has been cut on site with no evidence behind it. Each of these can undermine the whole door. Our fire door glazing guide covers the details.
Each installation includes:
- Re-glazing of damaged vision panels to the original system
- Fire-rated glass suited to the rating and location
- Evidence of the glazing system fitted
- Tested beads, glazing seals and fixings
Fire door law for Derry properties
Derry 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 Derry are checked. We hand over evidence that supports it.

Common questions
Is Derry within your coverage area?
It is. We cover Derry in County Londonderry and neighbouring towns such as Coleraine. There is no charge for the survey.
What happens on a survey in Derry?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
Are wired glass fire doors still acceptable?
Some older doors use wired glass. Whether it is acceptable depends on its fire rating and whether it meets safety glazing rules for that location. We advise case by case.
Can any toughened glass go in a fire door?
No. Fire doors need fire-rated glass of the type and size covered by the door's test evidence, fitted with the matching beads and seals. Standard toughened glass is not fire resisting.
