Regulatory Compliance Support

When correctly specified and installed, FD120 steel fire doors support compliance with:

• BS EN 1634-1
• Approved Document B
• The building’s fire risk assessment

FD120 steel fire doors offer a practical combination of certified fire protection, durability, and optional security, making them suitable for commercial, industrial, and multi-occupancy residential applications where 120 minute fire resistance is required.

FD120 steel fire doors are regulated life safety products and must comply with fire testing standards, Building Regulations, and hardware certification requirements. The declared 120 minute fire resistance is only valid when the door is supplied and installed as a complete certified door set.

Fire Resistance Testing – BS EN 1634-1

FD120 steel fire doors must be tested to BS EN 1634-1, confirming:

• Integrity (E) – Resistance to flame and hot gas passage
• Insulation (EI) – Heat transfer limitation (where specified)

Minimum 120 minutes fire resistance

The complete assembly — leaf, frame, seals, hinges, hardware, glazing, and louvres — must match the tested configuration.

Smoke Control (FD120S)

Where smoke protection is required, doors must include certified smoke seals and meet smoke leakage performance in accordance with relevant standards (often linked to BS 1634-3). These are classified as FD120S.

Building Regulations – Approved Document B

FD120 steel fire doors must align with Approved Document B (Fire Safety) and the building’s fire strategy, including:

• Correct fire resistance period
• Installation within designated compartment lines
• Protection of escape routes and stairwells

Specification should be based on the fire risk assessment.

Emergency Exit Hardware Standards (If Applicable)

Where forming part of an escape route, hardware must comply with:

• BS EN 1125 – Panic exit devices (public access areas)
• BS EN 179 – Emergency exit devices (staff-only areas)

All ironmongery must be approved for use within the certified fire door set.

CE / UKCA Marking (Where Applicable)

If supplied as an external fire door set, compliance may also require:

• EN 16034 – Fire resisting characteristics
• BS EN 14351-1 – External pedestrian doorsets
• CE and/or UKCA marking with Declaration of Performance

Security Standards (If Specified)

Where enhanced security is required, doors may also be tested to standards such as:

• LPS 1175Security upgrades must not compromise the fire certification.

Installation to Certified Detail

Installation must follow the manufacturer’s tested specification, including:

• Approved fixing methods
• Correct gap tolerances
• Compatible seals and hardware
• Certified glazing or louvre systems

Unauthorised modifications can invalidate the FD120 rating.

Ongoing Inspection and Maintenance

FD120 steel fire doors must be:

• Included in routine fire door inspections
• Checked for correct self-closing and latching
• Inspected for seal integrity and hardware condition
• Maintained in accordance with fire safety management procedures

When correctly specified, installed, and maintained, FD120 steel fire doors provide compliant 120-minute fire compartmentation in line with BS EN 1634-1, Building Regulations, and the building’s fire risk assessment.

FD120 steel fire doors must be installed and maintained in strict accordance with their certified test evidence. The 120 minute fire rating is only valid when the door is supplied, installed, and maintained as a complete approved door set.

Installation Requirements

Install as a Complete Certified Doorset

An FD120 steel fire door must include:

• Door leaf
• Frame
• Intumescent seals (and smoke seals if FD120S)
• HingesLatch/lock
• Door closer

Glazing or louvre system (if specified)

All components must match the configuration tested to BS EN 1634-1.

Structural Fixing

The frame must be securely fixed into a suitable fire rated wall construction using:

• Approved fixings
• Correct fixing centres
• Appropriate packing materials
• Gaps between frame and wall must be fire stopped with approved materials.

Correct Gap Tolerances

Clearances between the leaf and frame must comply with manufacturer guidance. Excessive gaps can compromise fire and smoke performance.

Self Closing Device

Most FD120 doors require a compliant door closer to ensure the door fully closes and latches after each use. The closer must be correctly adjusted at commissioning.

Glazing and Louvre Installation

If fitted, glazing panels or fire rated louvres must:

• Be installed using certified glazing systems
• Match the tested configuration
• Not exceed approved size limits

Retrofitting non-certified components invalidates the fire rating.

Hardware Compliance

All ironmongery must be fire rated and compatible with the certified door set. Emergency hardware must comply with:

• BS EN 1125 (panic bars)
• BS EN 179 (emergency push pads)

Supply Only Considerations

FD120 steel fire doors can be supplied for installation by competent contractors; however:

• Installation must follow certified instructions precisely
• Incorrect fitting may invalidate fire certification
• Compliance responsibility rests with the installer and building operator

Professional installation is strongly recommended for commercial and multi-occupancy buildings.

Maintenance Requirements

FD120 fire doors must form part of the building’s fire safety management plan.

Routine Inspection

Regular checks should confirm:

• Door self closes fully
• Latch engages correctly
• Intumescent and smoke seals are intact
• Hinges are secure
• No distortion or damage to leaf or frame

Hardware Inspection

• Door closer functioning correctly
• Panic or emergency hardware operating smoothly
• Locks and latches secure

Repairs and Adjustments

Any repairs must use approved components that match the original certified specification. Unauthorised alterations can invalidate the FD120 rating.

Inspection Frequency

In commercial and multi occupancy buildings, fire doors should be inspected at regular intervals (often annually as a minimum, or more frequently in high use environments).

When correctly installed and maintained in accordance with BS EN 1634-1 and Building Regulations, FD120 steel fire doors provide reliable 120-minute fire compartmentation and support safe evacuation strategies.
