Safety and visibility
Glass in doors also has to meet safety glazing rules, so the fire-rated glass chosen needs to be suitable for impact as well. For schools and care settings we also consider where the panel sits so that children or wheelchair users can see through it.
The regulations behind fire doors in County Londonderry
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.

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.

Questions
Do you provide glazed fire doors across County Londonderry?
Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
What happens if the glass in a fire door breaks?
It should be re-glazed with the same fire-rated glass and glazing system as the original. A temporary board or standard glass leaves the door non-compliant.
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.
