Fire Doors Save Lives

A fire door is a certified passive fire protection system designed to prevent the spread of fire and smoke between compartments within a building. Fire doors are tested as a complete doorset, including the door leaf, frame, seals and hardware, and are typically rated for 30 minutes (FD30) or 60 minutes (FD60) fire resistance.

Fire doors are a critical part of building fire strategies across commercial, residential and public sector buildings.

Fire doors play a key role in maintaining fire compartmentation, which helps control the spread of fire and smoke.

Correctly installed fire doors help to:

• Protect escape routes and stair cores
• Contain fire within designated compartments
• Reduce smoke spread through corridors and communal areas
• Provide additional time for safe evacuation
• Protect building structure and assets
• Support compliance with fire safety regulations

This is particularly important in high-occupancy buildings such as offices, residential blocks, student accommodation and retail spaces.

Fire doors are required in most modern buildings as part of the fire safety design.

They are commonly installed in:

• Office buildings
• Retail and commercial premises
• Residential apartment blocks
• High-rise developments
• Student accommodation
• Industrial and warehouse facilities
• New build developments
• Public sector buildings

Many government and regulated environments, including Ministry of Defence (MOD) and Ministry of Justice (MOJ) facilities, require strict compliance with fire door standards.

For a fire door to perform correctly, it must be installed as a complete certified system.

This typically includes:

• Fire-rated door leaf
• Fire-rated door frame or lining
• Intumescent and smoke seals
• Approved hinges
• Certified door closers
• Fire-rated locks, latches and handles
• Fire-rated glazing systems where required

Using uncertified or incompatible components can compromise the door’s fire resistance.

Correct clearances are essential to ensure fire doors perform as tested.

Typical installation tolerances include:

• 2–4mm gaps at the sides and top of the door
• Controlled clearance at the bottom depending on smoke seal requirements

If gaps are too large, fire and smoke can pass through before the intumescent seals activate, compromising the door’s ability to contain the fire.

Yes. In most commercial and multi-occupancy residential buildings, fire doors must be fitted with self-closing devices.

These ensure the door closes and latches automatically, maintaining fire compartmentation and preventing smoke and flames from spreading through escape routes.

Fire doors can only be modified within the manufacturer’s specified tolerances.

Excessive trimming, incorrect hardware installation or alterations to the door structure can:

• Invalidate certification
• Reduce fire resistance
• Cause compliance issues during inspections

Installation and modification should always be carried out by competent fire door specialists.

Fire doors should be regularly inspected and maintained as part of a building’s fire safety management plan.

Routine inspections typically check:

• Door alignment and closing action
• Operation of closers and latches
• Condition of hinges and ironmongery
• Integrity of intumescent seals
• Correct door gaps
• Damage to door leaves or frames

Regular inspections are particularly important in high-traffic buildings such as offices, retail spaces and student accommodation.

If a fire door fails during a fire:

• Fire can spread rapidly between compartments
• Smoke can fill escape routes
• Evacuation routes may become unsafe
• Damage to the building can increase significantly
• Liability may fall on those responsible for installation or maintenance

For this reason, correct installation and ongoing maintenance are essential.
