A Fire Door Framework:

Why Every Component Counts

PASSIVE FIRE protection and fire door hardware are intrinsically linked. Fire doors are tested as a complete assembly of certified hardware components, with performance relying on the coordination of each individual ironmongery product.

This crucial partnership is designed to contain fire and smoke when it matters most. However, even a seemingly minor fault- whether a loose hinge, damaged seal or an incorrectly adjusted door closer- can compromise the performance of an entire fire door assembly. If one element fails, the safety of a building and its occupants is put at risk.

Iain Banks of Allegion UK provides a detailed guide on the functional hardware behind fire doors, exploring how each component plays a vital role in protecting people, property and compliance.

Door Furniture

“ An appropriate handle is fundamental to the safe operation of a fire door. Where decorative hardware may suit an aesthetically driven application, fire doors are functional, and as such, door furniture should prioritise durability, practicality and ease of operation. There are two common handle types found on fire doors. Lever handles are typically fixed to latched fire doors, providing intuitive operation from either side of the door. Pull handles on the other hand, are generally used on unlatched doors and are particularly useful on larger, heavier fire doors where they are often paired with push plates.

“ Specification aside, door furniture must always remain securely fixed, with handles operating smoothly and returning freely to a horizontal position after use. Loose, damaged or missing handles can prevent the latch from engaging correctly, compromising the door’ s ability to provide effective compartmentalisation. To improve the durability of handles, bolt-through fixings are recommended as they secure the furniture through the door and the lock or latch case, reducing the likelihood of screws moving or loosening over time. Always remember, by securing installations this way, the door leaf is penetrated, and so, each fixing and component must be suitably fire-rated and compatible with the certified door assembly to maintain performance.”

Hinges

“ Fire door hinges perform one of the most demanding roles within the assembly by facilitating the necessary pivot action that provides movement to the door. To support the height and weight of a standard fire door, most timber assemblies require the installation of at least three certified hinges, with each positioned on the vertical edge of the door leaf and frame. For larger, heavier doors standing over 2.2 metres tall, a fourth hinge may be necessary.

“ In order to withstand frequent opening and closing cycles, accurate installation and regular maintenance is essential here. Each hinge must be present with all fixings secured using the correct screws supplied or specified by the manufacturer. Should a fire door become difficult to operate, it’ s important to check hinges for loose screws, signs of metal fragments or excessive oil leakage, all of which may indicate signs of wear. When damaged hinges are identified, they must be replaced with like-for-like certified products, with CE, UKCA or BS EN 1935 marks present and installed in accordance with the manufacturer’ s instructions.”

Door Closers

“ Door closers also play a central role in the movement of fire doors and are often regarded as one of most critical life-saving

devices in passive fire protection. Typically fixed to the top face of the door leaf, concealed inside a mortised pocket or built into the floor beneath the door pivot point, door closers provide the controlled closing action that ensures a fire door has reliably closed after every use. Controlled opening speeds also help to minimise a fire door’ s misuse by reducing impact damage. Such is their importance to fire door safety, closers are required on all flat entrance doors and fire doors located on escape routes.

“ Should a fire door fail to close and engage with the latch successfully, it may be that the closer has been incorrectly installed or damaged and, therefore, needs correcting or replacing. In some cases, a door closer may have been inappropriately adjusted or even mistakenly- or purposely- disconnected, completely invalidating the reliability and fire rating of the door assembly. Routine inspections should confirm that the door closer is present, is securely fixed and shows no signs of damage that may be stopping the door from closing from any open position. When checking the condition of a door closer, the door should close and engage the latch as intended when released from an approximate angle of 5 ° or 75mm.”
