Fire-Rated Glazed Doors

A fire-rated glazed door is a fire door with substantial glass in it, from a large vision panel to a fully glazed leaf, supplied as a tested doorset or to a certificated specification. The glass, beads, seals, frame, hinges, closer and lock all form part of the rating.

What does our fire-rated glazed doors service include?

We supply and install glazed fire doorsets in timber, steel and aluminium, single and double, as stand-alone doors or within glazed screens. We match the door to the rating and duty of its position, and fit it to the manufacturer's installation instructions.

  • Certificated glazed fire doorsets
  • Fully glazed steel and aluminium doors within screens
  • Timber doors with large vision panels
  • Matching side panels and fanlights
  • Ironmongery compatible with the door evidence
  • Hold-open devices linked to the alarm where specified

What should you check before ordering?

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.

Glazed area limits

Each door design allows a maximum glazed area and aperture positions. Bigger glass needs a door tested for it.

Escape route doors

Doors that subdivide corridors and doors that swing both ways normally need vision panels, and integrity-only glass in doors may be limited by building guidance on escape routes.

Closers and gaps

Self-closing devices and correct gaps are part of the performance. We set them at installation and record them.

Accessibility

Opening forces, vision panel zones and contrast need to work with accessibility guidance as well as fire.

Ongoing checks

Residential blocks in England over 11 metres need regular fire door checks under the Fire Safety (England) Regulations 2022; glazed doors are included.

What evidence do you get?

  • Doorset certificate or test evidence
  • Ironmongery schedule
  • Gap and closer settings at handover
  • Installer's completion record

Frequently asked questions

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.

Can a fire door be fully glazed?

Yes, some steel, aluminium and timber doorsets are tested with large or full-height glazing. The glass must be the type and size in the evidence.

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.
