Before you order in County Down
Doorset, not just a door
The safest route is a complete doorset with frame and hardware tested together. Mixing a leaf from one source with a frame from another needs evidence that covers the combination.
Accessibility
Opening forces, vision panel zones and contrast need to work with accessibility guidance as well as fire.
Glazed area limits
Each door design allows a maximum glazed area and aperture positions. Bigger glass needs a door tested for it.
Regulations for County Down projects
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.
FAQs for County Down
Can you add glass to my existing fire door?
Cutting new apertures into a fire door is only acceptable when done under the door manufacturer's or certification scheme's instructions. Often a new doorset is the safer answer.
Do glazed fire doors need special glass?
Yes. They need fire-resistant glass of the type and thickness tested, fitted with the specified beads and seals.
What does FD30 mean on a glazed door?
FD30 is a UK shorthand for a door providing 30 minutes' fire resistance. Under European classification the same door would be described with an E or EI rating, with S added where smoke control is tested.
